The diverse functions of jasmonates (JAs) in plant cells are reflected by the extensive reprogramming of gene expression after JA perception. Here, we review the transcriptome signatures associated with JA signalling in Arabidopsis thaliana and other plant species. Transcript profiling studies clearly highlight the renowned capacity of JAs to elicit evolutionarily distant metabolic pathways across the plant kingdom. However, JA-related transcriptomes show limited overlap and, for most cellular processes, the context in which the JA signal is perceived is crucial in shaping the response. This emphasizes that JA signal transduction is integrated into an elaborate signalling network.
茉莉酸类物质(JAs)在植物细胞中的多种功能通过JA感知后基因表达的广泛重编程得以体现。在此,我们综述了拟南芥和其他植物物种中与JA信号传导相关的转录组特征。转录谱分析研究清楚地突出了JAs在整个植物界引发进化上距离遥远的代谢途径的显著能力。然而,与JA相关的转录组显示出有限的重叠,并且对于大多数细胞过程而言,感知JA信号的背景在塑造响应中至关重要。这强调了JA信号转导被整合到一个复杂的信号网络中。
