Pathogen perception in plant roots is under-explored compared to that in shoots. In this issue of Cell Host & Microbe, Wang et al. characterize the phosphorylation-mediated signaling pathway that positively and negatively regulates plant resistance to bacterial wilt disease upon perception of a metabolite from the soil-borne vascular pathogen Ralstonia solanacearum.

沿着磷酸化路径走向根系免疫

与芽相比，植物根部的病原体感知尚未得到充分研究。在本期《细胞宿主与微生物》中，Wang 等人。描述了磷酸化介导的信号通路，该通路在感知土传维管病原体青枯菌的代谢物后，正向和负向调节植物对青枯病的抗性。
