蜂王和工蜂种姓是发育可塑性的典范系统。我们使用已建立的表达序列标签信息,对种姓发育过程中差异表达的基因进行基于基因本体论的注释。代谢调节成为一个主要主题,氧化还原酶和水解酶的表达因种级不同而不同。对上游区域的Motif搜索揭示了群体特有的基序,为种姓基因的顺式调控网络研究提供了一个切入点。对于被认为与生殖有关的基因,与减数分裂相关的因子被证明是高度保守的,而胚轴的一些决定因素要么没有明确的同源基因(大理石袋、格子、躯干),要么似乎在蜜蜂基因组中缺乏(躯干)。我们的结果是第一个基于基因组的倡议的结果,该倡议为女性种姓分化(代表发育可塑性)和生殖过程中的基因调控趋势提供了一个注解框架。
The honey bee queen and worker castes are a model system for developmental plasticity. We used established expressed sequence tag information for a Gene Ontology based annotation of genes that are differentially expressed during caste development. Metabolic regulation emerged as a major theme, with a caste-specific difference in the expression of oxidoreductases vs. hydrolases. Motif searches in upstream regions revealed group-specific motifs, providing an entry point to cis-regulatory network studies on caste genes. For genes putatively involved in reproduction, meiosis-associated factors came out as highly conserved, whereas some determinants of embryonic axes either do not have clear orthologs (bag of marbles, gurken, torso), or appear to be lacking (trunk) in the bee genome. Our results are the outcome of a first genome-based initiative to provide an annotated framework for trends in gene regulation during female caste differentiation (representing developmental plasticity) and reproduction.
