Data from: Key molecular processes of the diapause to post‐diapause quiescence transition in the alfalfa leafcutting bee Megachile rotundata identified by comparative transcriptome analysis

Insect diapause (dormancy) synchronizes an insect's life cycle to seasonal changes in the abiotic and biotic resources required for development and reproduction. Transcription analysis of diapause to post‐diapause quiescent transition in the alfalfa leafcutting bee Megachile rotundata Fabricius identifies 643 post‐diapause up‐regulated gene transcripts and 242 post‐diapause down‐regulated transcripts. The log2 fold change in gene expression levels ranges from −5 to 7. Transcripts from several pivotal diapause‐related processes, including chromatin remodelling, cellular signalling pathways, microRNA processing, anaerobic glycolysis, cell cycle arrest and neuroendocrine control, are identified as being differentially expressed during the diapause to post‐diapause transition. In conjunction with studies from other insect species, the data indicate that there are several common mechanisms of diapause control and maintenance.

昆虫滞育（休眠）可使其生命周期与生长发育及繁殖所需的非生物和生物资源的季节性变化同步。对苜蓿切叶蜂（Megachile rotundata Fabricius）滞育向滞育后静止期转变过程的转录分析显示，存在643个滞育后上调的基因转录本和242个滞育后下调的转录本。基因表达水平的log2倍变化范围为-5至7。在滞育向滞育后转变过程中，多个关键滞育相关过程（包括染色质重塑、细胞信号通路、microRNA加工、无氧糖酵解、细胞周期停滞及神经内分泌调控）的转录本被鉴定为差异表达。结合对其他昆虫物种的研究，这些数据表明滞育调控与维持存在若干共同机制。
