Abstract Adult fireflies exhibit unique flashing courtship signals, emitted by specialized light organs, which develop mostly independently from larval organs during the pupal stage. The mechanisms of adult organ development have not been thoroughly studied until now. Here we show that key homeobox transcription factors AlABD-B and AlUNC-4 regulate bioluminescence in firefly Aquatica leii . Interference with expression AlAbd-B AlUnc-4 genes results undeveloped or non-luminescent organs. regulates , they interact each other. activate luciferase gene AlLuc1 some peroxins. Four peroxins are involved import AlLUC1 into peroxisomes. Our study provides insights flash signal control fireflies.

Appendage regeneration relies on the formation of blastema, a heterogeneous cellular structure formed at injury site. However, little is known about early injury-activated signaling pathways that trigger blastema during appendage regeneration. Here, we provide compelling evidence extracellular signal-regulated kinase (ERK)-activated casein 2 (CK-2), which has not been previously implicated in regeneration, triggers leg American cockroach,

Genetic changes that enabled the evolution of eusociality have long captivated biologists. More recently, attention has focussed on consequences genome evolution. Studies reported higher molecular evolutionary rates in eusocial hymenopteran insects compared with their solitary relatives. To investigate genomic termites, we analysed nine genomes, including newly sequenced genomes from three non-eusocial cockroaches. Using a phylogenomic approach, found termite experienced lower synonymous substitutions than those cockroaches, possibly as result longer generation times. We identified non-synonymous cockroach and pervasive relaxed selection former (24–31% genes analysed) latter (2–4%). infer this is due to reductions effective population size, rather gene-specific effects (e.g. indirect caste-biased genes). no obvious signature increased genetic load postulate efficient purging deleterious alleles at colony level. Additionally, adaptations may underpin caste differentiation, such involved post-translational modifications. Our results provide insights into termites more broadly.

Thanks to the fast development of sequencing techniques and bioinformatics tools, genome an insect species for specific research purposes has become increasingly popular practice. Insect genomes not only provide sets gene sequences but also represent a change in focus from reductionism systemic biology field entomology. Using genomes, researchers are able identify study functions all members family, pathway, or network associated with trait interest. Comparative genomics studies new insights into evolution, addressing long-lasting controversies taxonomy. It is now feasible uncover genetic basis important traits by identifying variants using resequencing data individual insects, followed genome-wide association analysis. Here, we review current progress projects application uncovering phylogenetic relationships between insects unraveling mechanisms life-history traits. We summarize challenges sharing possible solutions. Finally, guidance fully deeply mining data.
