目前模式植物病原菌Pseudomonasanderingae与植物宿主相互作用的研究中,转化植株的产生过程冗长是一个限制。在这里,我们提出了一个简单的方法称为农单胞菌,其中我们quantifyP。利用抗生素混合物选择P.古印度的盘子。作为概念证明,我们证明PAMP受体的瞬时表达减少了细菌生长,宿主免疫基因的瞬时消耗和III型效应子的瞬时表达增加了细菌生长。农单胞菌测定中的细菌生长。我们表明,我们可以快速实现免疫组分的结构-功能分析,并测试免疫水解酶的功能。农单胞菌属方法是简单,快速和强大的常规疾病检测与各种pseudomonasstrains没有转化植物或细菌。农单胞菌检测为进一步全面分析植物免疫提供了可靠的方法。
The lengthy process to generate transformed plants is a limitation in current research on the interactions of the model plant pathogenPseudomonas syringaewith plant hosts. Here we present an easy method called agromonas, where we quantifyP. syringaegrowth in agroinfiltrated leaves ofNicotiana benthamianausing a cocktail of antibiotics to selectP. syringaeon plates. As a proof of concept, we demonstrate that transient expression of PAMP receptors reduces bacterial growth, and that transient depletion of a host immune gene and transient expression of a type‐III effector increaseP. syringaegrowth in agromonas assays. We show that we can rapidly achieve structure−function analysis of immune components and test the function of immune hydrolases. The agromonas method is easy, fast and robust for routine disease assays with variousPseudomonasstrains without transforming plants or bacteria. The agromonas assay offers a reliable approach for further comprehensive analysis of plant immunity.
