Plants can re‐programme their transcriptome, proteome and metabolome to deal with environmental and biotic stress. It has been shown that the rhizosphere microbiome has influence on the plant metabolome and on herbivore behaviour. In the present study, Trichoderma gamsii was isolated from Arabidopsis thaliana rhizosphere soil. The inoculation of roots of Arabidopsis thaliana with T. gamsii significantly inhibited the feeding behaviour of Trichoplusia ni and affected the metabolome as well as the content of phytohormones in Arabidopsis leaves. T. gamsii‐treated plant leaves had higher levels of amino acids and lower concentrations of sugars. In addition, T. gamsii‐treated plant leaves had more abscisic acid (ABA) and lower levels of salicylic acid (SA) and indole‐3‐acetic acid (IAA) in comparison with the untreated plants. Furthermore, the inoculation with T. gamsii on different signalling mutants showed that the induction of defences were SA‐dependent. These findings indicate that T. gamsii has potential as a new type of biocontrol agent to promote plant repellence to insect attacks.

甘西木霉通过改变叶子代谢组和植物激素影响草食动物对拟南芥的摄食行为

植物可以重新编程其转录组、蛋白质组和代谢组以应对环境和生物胁迫。研究表明，根际微生物组对植物代谢组和食草动物行为有影响。在本研究中，木霉是从拟南芥根际土壤中分离出来的。拟南芥根部接种T. gamsii可显着抑制粉纹夜蛾的取食行为，并影响拟南芥叶片的代谢组和植物激素含量。 T. gamsii处理的植物叶子具有较高水平的氨基酸和较低浓度的糖。此外，与未处理的植物相比， T. gamsii处理的植物叶子含有更多的脱落酸 (ABA) 和较低水平的水杨酸 (SA) 和吲哚-3-乙酸 (IAA)。此外，在不同的信号突变体上接种T. gamsii表明防御的诱导是 SA 依赖性的。这些发现表明， T. gamsii有潜力作为一种新型生物防治剂，促进植物抵御昆虫侵袭。
