Much progress has been made in understanding the environmental and hormonal systems regulating winter diapause. However, transcriptional regulation of summer diapause is still largely unknown, making it difficult to understand an all-around regulation profile of seasonal adaptation. To bridge this gap, comparison RNA-seq to profile the transcriptome and to examine differential gene expression profiles between non-diapause, summer diapause, and winter diapause groups were performed. A total number of 113 million reads were generated and assembled into 79,117 unigenes, with 37,492 unigenes categorized into 58 functional gene ontology groups, 25 clusters of orthologous group categories, and 256 Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. KEGG analysis mapped 2108 differentially expressed genes to 48 and 67 pathways for summer and winter diapauses, respectively. Enrichment statistics showed that 11 identical pathways similarly overlapped in the top 20 enriched functional groups both related to summer and winter diapauses. We also identified 35 key candidate genes for universal and differential functions related to summer and winter diapause preparation. Furthermore, we identified some genes involved in the signaling and metabolic pathways that may be the key drivers to integrate environmental signals into the summer and winter diapause preparation. The current study provided valuable insights into global molecular mechanisms underpinning diapause preparation.

参与准备夏季和冬季滞育的普遍和差异转录调控途径在 Pieris melete

在了解调节冬季滞育的环境和荷尔蒙系统方面取得了很大进展。然而,夏季滞育的转录调控在很大程度上仍然是未知的,因此很难理解季节性适应的全方位调控概况。为了弥补这一差距,进行了比较 RNA-seq 以分析转录组并检查非滞育、夏季滞育和冬季滞育组之间的差异基因表达谱。总共生成了 1.13 亿条 reads 并组装成 79,117 个 unigenes,其中 37,492 个 unigenes 分为 58 个功能基因本体组、25 个直系同源组类别和 256 个京都基因和基因组百科全书 (KEGG) 途径。KEGG 分析将 2108 个差异表达基因分别映射到夏季和冬季滞育的 48 和 67 条途径。富集统计显示,在与夏季和冬季滞育相关的前 20 个富集功能组中,有 11 条相同的途径类似地重叠。我们还确定了与夏季和冬季滞育准备相关的通用和差异功能的 35 个关键候选基因。此外,我们确定了一些参与信号和代谢途径的基因,这些基因可能是将环境信号整合到夏季和冬季滞育准备中的关键驱动因素。目前的研究为支持滞育准备的全球分子机制提供了有价值的见解。富集统计显示,在与夏季和冬季滞育相关的前 20 个富集功能组中,有 11 条相同的途径类似地重叠。我们还确定了与夏季和冬季滞育准备相关的通用和差异功能的 35 个关键候选基因。此外,我们确定了一些参与信号和代谢途径的基因,这些基因可能是将环境信号整合到夏季和冬季滞育准备中的关键驱动因素。目前的研究为支持滞育准备的全球分子机制提供了有价值的见解。富集统计显示,在与夏季和冬季滞育相关的前 20 个富集功能组中,有 11 条相同的途径类似地重叠。我们还确定了与夏季和冬季滞育准备相关的通用和差异功能的 35 个关键候选基因。此外,我们确定了一些参与信号和代谢途径的基因,这些基因可能是将环境信号整合到夏季和冬季滞育准备中的关键驱动因素。目前的研究为支持滞育准备的全球分子机制提供了有价值的见解。我们确定了一些参与信号和代谢途径的基因,这些基因可能是将环境信号整合到夏季和冬季滞育准备中的关键驱动因素。目前的研究为支持滞育准备的全球分子机制提供了有价值的见解。我们确定了一些参与信号和代谢途径的基因,这些基因可能是将环境信号整合到夏季和冬季滞育准备中的关键驱动因素。目前的研究为支持滞育准备的全球分子机制提供了有价值的见解。
