摘要/Abstract

摘要： 木霉菌是广泛应用于植物病害生物防治的微生物,具有多重植物病害生物防治机制,其中关于诱导抗性的研究取得明显进展。木霉菌能产生20余种微生物相关分子模式/损伤相关分子模式(MAMPs/DAMPs)分子,植物根系有相对应的大约30种受体或响应基因。木霉菌通过定殖植物根系使MAMPs/DAMPs与植物根系受体或响应基因互作,触发水杨酸、苿莉酸/乙烯等防御反应信号长距离传导至植物叶片,诱导植物叶片防御反应基因表达。将木霉菌诱导的植物转录组、蛋白质组、代谢组变化的信息相结合,能全面反映木霉菌?植物有益互作所激发的诱导抗病性的分子机理。

Abstract: Trichoderma spp. are widely used biocontol microbe against plant disease with multiple antagonistic mechanism. The significant advances in induced resistance mechanism have been made in recent years. Trichoderma can produce over 20 MAMPs or DAMPs, correspondingly plant roots have about 30 receptors or response genes. The Trichoderma colonization on roots is able to initiate interaction of MAMPs/DAMPs-root receptor or response gene, which then triggers long distance transduction of signals including salicylic acid and jasmonic acid/E tresponsible for induced expression of leaf defense genes against plant disease. Integration of information based on the changes of plant trancriptome, proteome and metabolome after Trichoderma colonization on roots can provide more comprehensive understanding to Trichoderma-plant beneficial interaction associated with the induced resistance against plant disease.

Key words: Trichodema, biological control, induced resistance, MAMPs, metabolome
