How does the plant decode self- and non-self-signals to balance immune response and growth?

植物通过检测病原体相关分子模式（PAMP）来感知微生物病原体，这是由细胞表面局部模式识别受体（PRR）介导的。PAMP的感知触发信号网络，其包括促分裂原活化蛋白激酶（MAPK）的活化、防御基因表达的活化，并最终导致PAMP触发的免疫（PTI）。激活的PRRs与下游MAPK之间的联系仍然是难以捉摸的。我们已经确定了潜在的候选磷蛋白，可以弥补我们对PRR信号传导的理解中的差距。在目前的项目中，基于受体的信号事件将与先进的蛋白质组学方法，分子遗传学方法和细胞生物学（使用共聚焦显微镜）进行研究。该项目还将涉及重要的蛋白质生物化学。

Plants sense microbial pathogens through the detection of pathogen associated molecular patterns (PAMP) and this is mediated by cell surface localised pattern recognition receptors (PRR). Perception of PAMPs triggers a signaling network that includes activation of mitogen activated protein kinases (MAPK), activation of defense gene expression and ultimately leads to PAMP triggered immunity (PTI). What connects activated PRRs to downstream MAPKs has remained elusive. We have identified potential candidate phospho-proteins that could bridge the gap in our understanding of PRR signaling. In the current project the receptor based signaling event will be studied with advanced proteomics approaches, molecular genetics approaches and cell biology (using confocal microscopy). The project will also involve significant protein biochemistry.
