茉莉酸（JA）信号在植物抵御坏死性病原体和草食性昆虫方面起着核心作用，这些病原体和草食性昆虫同时折磨着植物的根和芽。这一途径也在与有益微生物相互作用后被激活，可能导致诱导的系统性耐药性。茉莉酸甲酯（MeJA）激活茉莉酸甲酯信号通路会改变根释放的含碳化合物的组成，这些化合物是根际微生物群落结构的关键决定因素。本研究利用16S rRNA基因扩增子焦磷酸测序技术，研究了拟南芥JA防御信号通路激活对相关根际细菌群落结构的影响。施用MeJA不直接影响土壤微生物群落，但茉莉酸信号通路激活后，根际微生物群落组成发生显著变化。我们的研究结果表明，JA信号可能介导土壤中植物-细菌相互作用，以应对坏死性病原体和草食性昆虫的攻击。
Jasmonic acid (JA) signalling plays a central role in plant defences against necrotrophic pathogens and herbivorous insects, which afflict both roots and shoots. This pathway is also activated following the interaction with beneficial microbes that may lead to induced systemic resistance. Activation of the JA signalling pathway via application of methyl jasmonate (MeJA) alters the composition of carbon containing compounds released by roots, which are implicated as key determinants of rhizosphere microbial community structure. In this study, we investigated the influence of the JA defence signalling pathway activation in Arabidopsis thaliana on the structure of associated rhizosphere bacterial communities using 16S rRNA gene amplicon pyrosequencing. Application of MeJA did not directly influence bulk soil microbial communities but significant changes in rhizosphere community composition were observed upon activation of the jasmonate signalling pathway. Our results suggest that JA signalling may mediate plant-bacteria interactions in the soil upon necrotrophic pathogen and herbivorous insect attacks.
