Abstract

Insects display an immense diversity in melanin pigmentation, which is generated by the interplay between the regulatory genes (that provide general patterning information) and effector genes (that provide coloration of the pattern). However, recent studies encompassing several different orders (Hemiptera, Blattodea, Coleoptera, and Lepidoptera) have shown that knockdowns of melanin producing genes alone can generate distinct region-specific patterns. This review surveys the most recent studies to further document the regional patterning of effector genes, and highlights the new advances and their implications for future research.

摘要

昆虫的黑色素沉着表现出极大的多样性，这种多样性是由调节基因（提供一般的图案信息）和效应基因（提供图案的颜色）相互作用产生的。然而，最近涵盖几个不同目的（半翅目、直翅目、鞘翅目和鳞翅目）的研究表明，仅敲低黑色素生成基因就可以产生独特的区域特异性图案。这篇综述调查了最近的研究，以进一步记录效应基因的区域性模式，并强调了新的进展及其对未来研究的意义。
