Maize plants respond by triggering defense signaling, changes in gene expression, and biosynthesis of specialized metabolites. Leaves of maize inbred line B73, which has an available genome sequence, were infested with S. exigua for 1 to 24 h, followed by comparisons of the transcript and metabolite profiles with those of uninfested controls. The most extensive gene expression responses occurred rapidly, within 4 to 6 h after caterpillar infestation. However, both gene expression and metabolite profiles were altered within 1 h and continued to change during the entire 24 h experiment

玉米植株可通过启动防御信号转导、调控基因表达改变以及合成特化代谢物产生应激响应。本研究选取已完成全基因组测序的玉米近交系B73的叶片，用甜菜夜蛾（S. exigua）侵染处理1至24小时，随后将处理组的转录组与代谢组图谱与未接虫对照组进行对比分析。结果显示，虫害侵染后4至6小时内，基因表达的响应最为迅速且显著；但无论基因表达还是代谢组图谱，在侵染1小时内即发生改变，并在整个24小时实验周期中持续发生动态变化。
