(Summary) Soybean seeds and sprouts contain isoflavones, including aglycones, glucosides, and malonylated glucosides, and their contents vary across soybean varieties. During germination and photomorphogenesis, blue light-emitting diode (LED) irradiation suppressed hypocotyl growth and enhanced the expression levels of chalcone synthase 7, isoflavone synthase (IFS), and isoflavone reductase (IFR). Conversely, red LED irradiation enhanced hypocotyl growth and decreased the expression levels of IFS and IFR. The contents of some glycosides or malonylated glycosides in sprouts and young green soybeans were significantly higher under blue LED irradiation than under red LED irradiation. These results imply that blue light more effectively increased the concentrations of some isoflavones during early germination and/or hydroponics cultivation.

Kohei Kawamoto, Yoshiyasu Ishimaru, Sayuri Tomonari, Takahito Watanabe, Sumihare Noji and Taro Mito : Myoglianin is a crucial factor for the transition to the juvenile hormone-dependent phase during hemimetabolous nymphal development., Insect Biochemistry and Molecular Biology, 178, 104274, 2025. (Summary) In hemimetabolous insects, the developmental process of nymphs is divided into three growth phases, i.e., juvenile hormone (JH)-independent, JH-dependent, and JH-free phases. The wing primordium in hemimetabolous insects is formed latently in the JH-independent phase and manifests and grows in the JH-dependent phase. Myoglianin (Myo) is known to be a key factor of metamorphosis in the JH-free phase of nymphs, regulating negatively JH synthesis. Here we find the role of Myo in earlier phases in the cricket Gryllus bimaculatus via gene knockout analysis using CRISPR/Cas9. In the myo knockout (KO) mutants, developmental delay during embryogenesis was observed, and nymphal body size and the timing of molting were affected. The KO nymphs underwent multiple molts, typically around seven, but remained significantly smaller in body size compared to wild-type individuals. The KO nymphs also did not exhibit the expected growth of wing primordia, implying that transition to JH-dependent phase was failed. This failure in phase transition could have been caused by excessive JH because titers of JH I and JH II were remarkably increased in the KO mutants. Our results suggest that Myo plays a crucial role not only in regulating timing of molting but also in the transition to the nymphal growth phases associated with growth of wing primordia and nymphal body size.

(Summary) The DOPA-decarboxylase (DDC) gene is crucial for dopamine synthesis and influences various biological functions in insects, including body coloration, behavior, learning, and sleep. However, its evolutionary impact remains largely unexplored. This study reports on the tandem duplication of two bona fide ddc genes (ddc1 and ddc2) in the Gryllidae cricket family. We herein investigated the function of ddc1 and ddc2 using Gryllus bimaculatus (Gb) as a model. Our results revealed that Gb'ddc1 was expressed systemically, with its expression being higher immediately after molting compared to the stage following melanin pigmentation. In homozygous knockout mutants of Gb'ddc1, generated via CRISPR/Cas9, reduced body color pigmentation and had translucent cuticles, decreased dopamine levels, and over-accumulated DOPA. These mutants died shortly after hatching, likely due to cuticle defects, underscoring the essential role of dopamine, produced by Gb'ddc1, in melanin synthesis. Conversely, Gb'ddc2 expression was confined to the ovary and was not up-regulated after molting. Homozygous knockout mutants of Gb'ddc2 exhibited no body color defects, whereas hatchability and embryonic development rates were significantly reduced. Interestingly, dopamine levels in the ovaries were significantly elevated in Gb'ddc2 mutants. This suggests that normal ovarian dopamine levels, modulated by Gb'ddc2, are vital for fertility maintenance. The function of Gb'ddc2 differs from that of typical ddc, indicating neofunctionalization through evolutionary duplication. Overall, Gb'ddc1 and Gb'ddc2 have distinct functions, and precise regulation of ovarian dopamine levels using these two ddc genes may have enhanced cricket fertility.

Yuji Matsuoka, Taro Nakamura, Takahito Watanabe, Austen A Barnett, Sayuri Tomonari, Guillem Ylla, Carrie A Whittle, Sumihare Noji, Taro Mito and Cassandra G Extavour : Establishment of CRISPR/Cas9-based knock-in in a hemimetabolous insect: targeted gene tagging in the cricket Gryllus bimaculatus, Development, 152, 1, dev199746, 2025. (Summary) Studies of traditional model organisms such as the fruit fly Drosophila melanogaster have contributed immensely to our understanding of the genetic basis of developmental processes. However, the generalizability of these findings cannot be confirmed without functional genetic analyses in additional organisms. Direct genome editing using targeted nucleases has the potential to transform hitherto poorly understood organisms into viable laboratory organisms for functional genetic study. To this end, we present a method to induce targeted genome knockout and knock-in of desired sequences in an insect that serves as an informative contrast to Drosophila, the cricket Gryllus bimaculatus. The efficiency of germline transmission of induced mutations is comparable with that reported for other well-studied laboratory organisms, and knock-ins targeting introns yield viable, fertile animals in which knock-in events are directly detectable by visualization of a fluorescent marker in the expression pattern of the targeted gene. Combined with the recently assembled and annotated genome of this cricket, this knock-in/knockout method increases the viability of G. bimaculatus as a tractable system for functional genetics in a basally branching insect.

Takahisa Yamashita, Takahiro Ohde, Taro Nakamura, Yoshiyasu Ishimaru, Takahito Watanabe, Sayuri Tomonari, Yuki Nakamura, Sumihare Noji and Taro Mito : Involvement of the scalloped gene in morphogenesis of the wing margin via regulating cell growth in a hemimetabolous insect Gryllus bimaculatus., Development Growth & Differentiation, 65, 6, 348-359, 2023. (Summary) The acquisition of wings was a key event in insect evolution. As hemimetabolous insects were the first group to acquire functional wings, establishing the mechanisms of wing formation in this group could provide useful insights into their evolution. In this study, we aimed to elucidate the expression and function of the gene scalloped (sd), which is involved in wing formation in Drosophila melanogaster, and in Gryllus bimaculatus mainly during postembryonic development. Expression analysis showed that sd is expressed in the tergal edge, legs, antennae, labrum, and cerci during embryogenesis and in the distal margin of the wing pads from at least the sixth instar in the mid to late stages. Because sd knockout caused early lethality, nymphal RNA interference experiments were performed. Malformations were observed in the wings, ovipositor, and antennae. By analyzing the effects on wing morphology, it was revealed that sd is mainly involved in the formation of the margin, possibly through the regulation of cell proliferation. In conclusion, sd might regulate the local growth of wing pads and influence wing margin morphology in Gryllus.

(Summary) Insect body colors and patterns change markedly during development in some species as they adapt to their surroundings. The contribution of melanin and sclerotin pigments, both of which are synthesized from dopamine, to cuticle tanning has been well studied. Nevertheless, little is known about how insects alter their body color patterns. To investigate this mechanism, the cricket Gryllus bimaculatus, whose body color patterns change during postembryonic development, was used as a model in this study. We focused on the ebony and tan genes, which encode enzymes that catalyze the synthesis and degradation, respectively, of the precursor of yellow sclerotin N-β-alanyl dopamine (NBAD). Expression of the G. bimaculatus (Gb) ebony and tan transcripts tended to be elevated just after hatching and the molting period. We found that dynamic alterations in the combined expression levels of Gb'ebony and Gb'tan correlated with the body color transition from the nymphal stages to the adult. The body color of Gb'ebony knockout mutants generated by CRISPR/Cas9 systemically darkened. Meanwhile, Gb'tan knockout mutants displayed a yellow color in certain areas and stages. The phenotypes of the Gb'ebony and Gb'tan mutants probably result from an over-production of melanin and yellow sclerotin NBAD, respectively. Overall, stage-specific body color patterns in the postembryonic stages of the cricket are governed by the combinatorial expression of Gb'ebony and Gb'tan. Our findings provide insights into the mechanism by which insects evolve adaptive body coloration at each developmental stage.

Yuki Nakamura, Sayuri Tomonari, Kohei Kawamoto, Takahisa Yamashita, Takahito Watanabe, Yoshiyasu Ishimaru, Sumihare Noji and Taro Mito : Evolutionarily conserved function of the even-skipped ortholog in insects revealed by gene knock-out analyses in Gryllus bimaculatus., Developmental Biology, 485, 1-8, 2022. (Summary) Comparing the developmental mechanisms of segmentation among insects with different modes of embryogenesis provides insights on how the function of segmentation genes evolved. Functional analysis of eve by genetic mutants shows that the Drosophila pair-rule gene, even-skipped (eve), contributes to initial segmental patterning. However, eve orthologs tends to have diverse functions in other insects. To compare the evolutionary functional divergence of this gene, we evaluated eve function in a phylogenetically basal insect, the cricket Gryllus bimaculatus. To investigate the phenotypic effects of eve gene knock-out, we generated CRISPR/Cas9 system-mediated mutant strains of the cricket. CRISPR/Cas9 mutagenesis of multiple independent sites in the eve coding region revealed that eve null mutant embryos were defective in forming the gnathal, thoracic, and abdominal segments, consequently shortening the anterior-posterior axis. In contrast, the structures of the anterior and posterior ends (e.g., antenna, labrum, and cercus) formed normally. Hox gene expression in the gnathal, thoracic, and abdominal segments was detected in the mutant embryos. Overall, this study showed that Gryllus eve plays an important role in embryonic elongation and the formation of segmental boundaries in the gnathal to abdominal region of crickets. In the light of studies on other species, the eve function shown in Gryllus might be ancestral in insects.

(Summary) Most of our knowledge of insect genomes comes from Holometabolous species, which undergo complete metamorphosis and have genomes typically under 2 Gb with little signs of DNA methylation. In contrast, Hemimetabolous insects undergo the presumed ancestral process of incomplete metamorphosis, and have larger genomes with high levels of DNA methylation. Hemimetabolous species from the Orthopteran order (grasshoppers and crickets) have some of the largest known insect genomes. What drives the evolution of these unusual insect genome sizes, remains unknown. Here we report the sequencing, assembly and annotation of the 1.66-Gb genome of the Mediterranean field cricket Gryllus bimaculatus, and the annotation of the 1.60-Gb genome of the Hawaiian cricket Laupala kohalensis. We compare these two cricket genomes with those of 14 additional insects and find evidence that hemimetabolous genomes expanded due to transposable element activity. Based on the ratio of observed to expected CpG sites, we find higher conservation and stronger purifying selection of methylated genes than non-methylated genes. Finally, our analysis suggests an expansion of the pickpocket class V gene family in crickets, which we speculate might play a role in the evolution of cricket courtship, including their characteristic chirping.

Series B, Biological Sciences, 374, 1783, 20190225, 2019. (Summary) Juvenile hormones and the genetic interaction between the transcription factors Krüppel homologue 1 (Kr-h1) and Broad (Br) regulate the transformation of insects from immature to adult forms in both types of metamorphosis (holometaboly with a pupal stage versus hemimetaboly with no pupal stage); however, knowledge about the exact instar in which this occurs is limited. Using the hemimetabolous cricket Gryllus bimaculatus (Gb), we demonstrate that a genetic interaction occurs among Gb'Kr-h1, Gb'Br and the adult-specifier transcription factor Gb'E93 from the sixth to final (eighth) nymphal instar. Gb'Kr-h1 and Gb'Br mRNAs were strongly expressed in the abdominal tissues of sixth instar nymphs, with precocious adult moults being induced by Gb'Kr-h1 or Gb'Br knockdown in the sixth instar. The depletion of Gb'Kr-h1 or Gb'Br upregulates Gb'E93 in the sixth instar. By contrast, Gb'E93 knockdown at the sixth instar prevents nymphs transitioning to adults, instead producing supernumerary nymphs. Gb'E93 also represses Gb'Kr-h1 and Gb'Br expression in the penultimate nymphal instar, demonstrating its important role in adult differentiation. Our results suggest that the regulatory mechanisms underlying the pupal transition in holometabolous insects are evolutionarily conserved in hemimetabolous G. bimaculatus, with the penultimate and final nymphal periods being equivalent to the pupal stage. This article is part of the theme issue 'The evolution of complete metamorphosis'.

Kamenura Norio, Mayumi Sugimoto, Tamehiro Norimasa, Adachi Reiko, Sayuri Tomonari, Takahito Watanabe and Taro Mito : Cross-allergenicity of crustacean and the edible insect Gryllus bimaculatus in patients with shrimp allergy, Molecular Immunology, 106, 127-134, 2019. (Summary) Food scarcity is a serious problem for many developing as well as developed countries. Edible insects have attracted attention recently as a novel food source. Crickets are especially high in nutritional value and easy to breed and harvest. In this study, we evaluated the risk of allergic reactions associated with cricket consumption in individuals with crustacean allergy. We evaluated food allergy risk in the consumption of Gryllus bimaculatus (cricket) in patients with shrimp allergy, using enzyme-linked immunosorbent assay (ELISA) and IgE crosslinking-induced luciferase expression assay (EXiLE). Sera from individuals with shrimp allergy (positive for shrimp-specific IgE by ImmunoCAP (>0.35 UA/mL; n = 9) or without shrimp allergy (negative for shrimp-specific IgE; n = 6) were obtained. There was a strong correlation between shrimp- and Gryllus-specific IgE levels obtained by ELISA (r = 0.99; P < 0.001). The binding of shrimp-specific IgE on shrimp allergen was dose-dependently inhibited by Gryllus allergen (0-1.0 mg/mL). There was a strong correlation between shrimp- and Gryllus-specific IgE responses, as assessed by EXiLE assays (r = 0.89; P < 0.001). We determined that a protein of approximately 40 kDa reacted with the positive, but not negative, sera for shrimp-specific IgE by ImmunoCAP. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis identified the major allergen in shrimp and Gryllus to be tropomyosin. Our data suggest that the cricket allergen has the potential to induce an allergic reaction in individuals with crustacean allergy. Therefore, allergy risk and shrimp-specific IgE levels should be considered before consumption of cricket meal.

(Summary) Parthenocarpy in horticultural crop plants is an important trait with agricultural value for various industrial purposes as well as direct eating quality. Here, we demonstrate a breeding strategy to generate parthenocarpic tomato plants using the CRISPR/Cas9 system. We optimized the CRISPR/Cas9 system to introduce somatic mutations effectively into SlIAA9-a key gene controlling parthenocarpy-with mutation rates of up to 100% in the T0 generation. Furthermore, analysis of off-target mutations using deep sequencing indicated that our customized gRNAs induced no additional mutations in the host genome. Regenerated mutants exhibited morphological changes in leaf shape and seedless fruit-a characteristic of parthenocarpic tomato. And the segregated next generation (T1) also showed a severe phenotype associated with the homozygous mutated genome. The system developed here could be applied to produce parthenocarpic tomato in a wide variety of cultivars, as well as other major horticultural crops, using this precise and rapid breeding technique.

(Summary) Genome editing using the CRISPR/Cas9 system can be used to modify plant genomes, however, improvements in specificity and applicability are still needed in order for the editing technique to be useful in various plant species. Here, using genome editing mediated by a truncated gRNA (tru-gRNA)/Cas9 combination, we generated new alleles for OST2, a proton pump in Arabidopsis, with no off-target effects. By following expression of Cas9 and the tru-gRNAs, newly generated mutations in CRIPSR/Cas9 transgenic plants were detected with high average mutation rates of up to 32.8% and no off-target effects using constitutive promoter. Reducing nuclear localization signals in Cas9 decreased the mutation rate. In contrast, tru-gRNA Cas9 cassettes driven by meristematic- and reproductive-tissue-specific promoters increased the heritable mutation rate in Arabidopsis, showing that high expression in the germ line can produce bi-allelic mutations. Finally, the new mutant alleles obtained for OST2 exhibited altered stomatal closing in response to environmental conditions. These results suggest further applications in molecular breeding to improve plant function using optimized plant CRISPR/Cas9 systems.

(Summary) Although butterflies undergo a dramatic morphological transformation from larva to adult via a pupal stage (holometamorphosis), crickets undergo a metamorphosis from nymph to adult without formation of a pupa (hemimetamorphosis). Despite these differences, both processes are regulated by common mechanisms that involve 20-hydroxyecdysone (20E) and juvenile hormone (JH). JH regulates many aspects of insect physiology, such as development, reproduction, diapause, and metamorphosis. Consequently, strict regulation of JH levels is crucial throughout an insect's life cycle. However, it remains unclear how JH synthesis is regulated. Here, we report that in the corpora allata of the cricket, Gryllus bimaculatus, Myoglianin (Gb'Myo), a homolog of Drosophila Myoglianin/vertebrate GDF8/11, is involved in the down-regulation of JH production by suppressing the expression of a gene encoding JH acid O-methyltransferase, Gb'jhamt In contrast, JH production is up-regulated by Decapentaplegic (Gb'Dpp) and Glass-bottom boat/60A (Gb'Gbb) signaling that occurs as part of the transcriptional activation of Gb'jhamt Gb'Myo defines the nature of each developmental transition by regulating JH titer and the interactions between JH and 20E. When Gb'myo expression is suppressed, the activation of Gb'jhamt expression and secretion of 20E induce molting, thereby leading to the next instar before the last nymphal instar. Conversely, high Gb'myo expression induces metamorphosis during the last nymphal instar through the cessation of JH synthesis. Gb'myo also regulates final insect size. Because Myo/GDF8/11 and Dpp/bone morphogenetic protein (BMP)2/4-Gbb/BMP5-8 are conserved in both invertebrates and vertebrates, the present findings provide common regulatory mechanisms for endocrine control of animal development.

(Summary) Elucidation of reinforcement mechanisms in associative learning is an important subject in neuroscience. In mammals, dopamine neurons are thought to play critical roles in mediating both appetitive and aversive reinforcement. Our pharmacological studies suggested that octopamine and dopamine neurons mediate reward and punishment, respectively, in crickets, but recent studies in fruit-flies concluded that dopamine neurons mediates both reward and punishment, via the type 1 dopamine receptor Dop1. To resolve the discrepancy between studies in different insect species, we produced Dop1 knockout crickets using the CRISPR/Cas9 system and found that they are defective in aversive learning with sodium chloride punishment but not appetitive learning with water or sucrose reward. The results suggest that dopamine and octopamine neurons mediate aversive and appetitive reinforcement, respectively, in crickets. We suggest unexpected diversity in neurotransmitters mediating appetitive reinforcement between crickets and fruit-flies, although the neurotransmitter mediating aversive reinforcement is conserved. This study demonstrates usefulness of the CRISPR/Cas9 system for producing knockout animals for the study of learning and memory.

(Summary) In insect species that undergo long germ segmentation, such as Drosophila, all segments are specified simultaneously at the early blastoderm stage. As embryogenesis progresses, the expression boundaries of Hox genes are established by repression of gap genes, which is subsequently replaced by Polycomb group (PcG) silencing. At present, however, it is not known whether patterning occurs this way in a more ancestral (short germ) mode of embryogenesis, where segments are added gradually during posterior elongation. In this study, two members of the PcG family, Enhancer of zeste (E(z)) and Suppressor of zeste 12 (Su(z)12), were analyzed in the short germ cricket, Gryllus bimaculatus. Results suggest that although stepwise negative regulation by gap and PcG genes is present in anterior members of the Hox cluster, it does not account for regulation of two posterior Hox genes, abdominal-A (abd-A) and Abdominal-B (Abd-B). Instead, abd-A and Abd-B are predominantly regulated by PcG genes, which is the mode present in vertebrates. These findings suggest that an intriguing transition of the PcG-mediated silencing of Hox genes may have occurred during animal evolution. The ancestral bilaterian state may have resembled the current vertebrate mode of regulation, where PcG-mediated silencing of Hox genes occurs before their expression is initiated and is responsible for the establishment of individual expression domains. Then, during insect evolution, the repression by transcription factors may have been acquired in anterior Hox genes of short germ insects, while PcG silencing was maintained in posterior Hox genes.

(Summary) Hemimetabolous, or incompletely metamorphosing, insects are phylogenetically basal. These insects include many deleterious species. The cricket, Gryllus bimaculatus, is an emerging model for hemimetabolous insects, based on the success of RNA interference (RNAi)-based gene-functional analyses and transgenic technology. Taking advantage of genome-editing technologies in this species would greatly promote functional genomics studies. Genome editing using transcription activator-like effector nucleases (TALENs) has proven to be an effective method for site-specific genome manipulation in various species. TALENs are artificial nucleases that are capable of inducing DNA double-strand breaks into specified target sequences. Here, we describe a protocol for TALEN-based gene knockout in G. bimaculatus, including a mutant selection scheme via mutation detection assays, for generating homozygous knockout organisms.

(Summary) Many researchers are using crickets to conduct research on various topics related to development and regeneration in addition to brain function, behavior, and biological clocks, using advanced functional and perturbational technologies such as genome editing. Recently, crickets have also been attracting attention as a food source for the next generation of humans. In addition, crickets are increasingly being used as disease models and biological factories for pharmaceuticals. Cricket research has thus evolved over the last century from use primarily in highly important basic research, to use in a variety of applications and practical uses. These insects are now a state-of-the-art model animal that can be obtained and maintained in large quantities at low cost. We therefore suggest that crickets are useful as a third domesticated insect for scientific research, after honeybees and silkworms, contributing to the achievement of global sustainable development goals.
