Transcriptome analysis of S. glabra in response to MeJA

We studied the MeJA response processes at four time points in Sindora glabra, which accumulates abundant sesquiterpenes in the tree trunk. Across the time course, differentially expressed genes involved in terpenoid backbone biosynthesis were significantly enriched, while JAZ genes involved in jasmonic acid pathway and TGA genes involved in salicylic acid pathway were significantly enriched at later time point after treatment. Overall design: 12 samples were analyzed after MeJA treatment, each treatment contained three replicates

本研究以树干中富含倍半萜（sesquiterpenes）的油楠（Sindora glabra）为材料，解析其在茉莉酸甲酯（MeJA）处理后的四个时间点的响应过程。在整个处理时间进程中，参与萜类骨架生物合成途径的差异表达基因显著富集；而参与茉莉酸信号通路的JAZ基因以及参与水杨酸信号通路的TGA基因，则在处理后的后期时间点呈现显著富集特征。实验设计：共对茉莉酸甲酯处理后的12个样本进行分析，每个处理组设置3次生物学重复。
