热胁迫下大岩桐花的转录组分析
Journal: Agricultural Science DOI: 10.12238/as.v5i3.2154
Abstract
试验以常温培养(WT)和高温胁迫(mut)的大岩桐花蕾为材料进行转录组学测序分析,WT组和mut组共有1885个差异表达基因,在胁迫响应、多生物过程以及温度响应等方面存在显著差异；与通路相关的差异表达基因主要富集在植物信号转导和内质网蛋白加工等方面；转录因子预测分析发现AP2/ERF类、bHLH、MYB-related、C2H2和NAC等转录因子在大岩桐响应高温胁迫时表达量较高,这些转录因子与植物激素信息转导和内质网蛋白加工有关的基因成为大岩桐响应高温胁迫的重要候选基因。
