The T2T Genome of the Domesticated Silkworm .

Genome sequences contain the fundamental genetic information that largely determines the biology of a species. Over the past 20 years, advancements in high-throughput sequencing technologies and bioinformatics tools have matured, facilitating genome assembly and ushering in the telomere-to-telomere (T2T) era. is renowned as a silk-producing insect and serves as an important model organism extensively studied across various fields of biology.

Leading with purpose: Unraveling the impact of responsible leadership on employee green behavior in the workplace.

Although sustainability has been a priority for organizations, there is still a lack of research on how leaders with a stakeholder perspective can motivate employees to adopt green behavior for sustainability in a complex and changing environment. This paper introduced social cognitive theory to describe two mechanisms by which responsible leadership predicts employee green behavior. Our research considers felt obligation for constructive change and stakeholder value as mediations with cognitive perspective in this process.

Lepidopteran wing scales contain abundant cross-linked film-forming histidine-rich cuticular proteins.

Scales are symbolic characteristic of Lepidoptera; however, nothing is known about the contribution of cuticular proteins (CPs) to the complex patterning of lepidopteran scales. This is because scales are resistant to solubilization, thus hindering molecular studies. Here we succeeded in dissolving developing wing scales from Bombyx mori, allowing analysis of their protein composition.

Circadian regulation of night feeding and daytime detoxification in a formidable Asian pest Spodoptera litura.

Voracious feeding, trans-continental migration and insecticide resistance make Spodoptera litura among the most difficult Asian agricultural pests to control. Larvae exhibit strong circadian behavior, feeding actively at night and hiding in soil during daytime. The daily pattern of larval metabolism was reversed, with higher transcription levels of genes for digestion (amylase, protease, lipase) and detoxification (CYP450s, GSTs, COEs) in daytime than at night.

The POU Transcription Factor POU-M2 Regulates Gene Expression in the Silkworm, .

Vitellogenin receptors (VgRs) play critical roles in egg formation by transporting vitellogenin (Vg) into oocytes in insects. Although the function of VgR in insects is well studied, the transcriptional regulation of this gene is still unclear. Here, we cloned the promoter of the gene from (), and predicted many POU cis-response elements (CREs) in its promoter.

Genome-wide annotation and comparative analysis of cuticular protein genes in the noctuid pest Spodoptera litura.

Insect cuticle is considered an adaptable and versatile building material with roles in the construction and function of exoskeleton. Its physical properties are varied, as the biological requirements differ among diverse structures and change during the life cycle of the insect. Although the bulk of cuticle consists basically of cuticular proteins (CPs) associated with chitin, the degree of cuticular sclerotization is an important factor in determining its physical properties.
