Abstract

In social insects, interactions among colony members trigger caste differentiation with morphological modifications. During caste differentiation in termites, body parts and caste-specific morphologies are modified during postembryonic development under endocrine controls such as juvenile hormone (JH) and ecdysone. In addition to endocrine factors, developmental toolkit genes such as Hox- and appendage-patterning genes also contribute to the caste-specific body part modifications. These toolkits are thought to provide spatial information for specific morphogenesis. During social evolution, the complex crosstalks between physiological and developmental mechanisms should be established, leading to the sophisticated caste systems. This article reviews recent studies on these mechanisms underlying the termite caste differentiation and addresses implications for the evolution of caste systems in termites.

白蚁种姓分化过程中身体部位的特异性发育：激素作用与发育工具包基因之间的串扰。

在社会性昆虫中，群体成员之间的相互作用会引发种姓分化和形态改变。在白蚁的种姓分化过程中，身体部位和种姓特异性形态在胚后发育过程中受内分泌（如幼虫激素和蜕皮激素）的控制而发生改变。除内分泌因素外，Hox 基因和附肢形态基因等发育工具包基因也有助于白蚁种姓特异性身体部位的改变。这些工具箱被认为为特定的形态发生提供了空间信息。在社会进化过程中，生理和发育机制之间应建立起复杂的联系，从而形成复杂的种姓系统。本文回顾了白蚁种姓分化机制的最新研究，并探讨了白蚁种姓系统进化的意义。

期刊介绍： Current Opinion in Insect Science is a new systematic review journal that aims to provide specialists with a unique and educational platform to keep up–to–date with the expanding volume of information published in the field of Insect Science. As this is such a broad discipline, we have determined themed sections each of which is reviewed once a year. The following 11 areas are covered by Current Opinion in Insect Science. -Ecology -Insect genomics -Global Change Biology -Molecular Physiology (Including Immunity) -Pests and Resistance -Parasites, Parasitoids and Biological Control -Behavioural Ecology -Development and Regulation -Social Insects -Neuroscience -Vectors and Medical and Veterinary Entomology There is also a section that changes every year to reflect hot topics in the field. Section Editors, who are major authorities in their area, are appointed by the Editors of the journal. They divide their section into a number of topics, ensuring that the field is comprehensively covered and that all issues of current importance are emphasized. Section Editors commission articles from leading scientists on each topic that they have selected and the commissioned authors write short review articles in which they present recent developments in their subject, emphasizing the aspects that, in their opinion, are most important. In addition, they provide short annotations to the papers that they consider to be most interesting from all those published in their topic over the previous year.
