Tomato leaf mold is a common disease in tomato production and severely impacts the growth, fruit quality and yield of tomato plants. Research on tomato leaf mold has a long history and has focused mainly on the differentiation of pathogen races, the structure and function of pathogen Avr gene products, the cloning of Cf resistance genes and the analysis of disease resistance mechanisms. Interactions between Cf and Avr are in accordance with the "gene-for-gene" hypothesis and typical Cf/Avr interactions are part of effector-triggered immunity (ETI). However, an increasing number of studies have proven that pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) is involved in the disease resistance response system mediated by Cf genes. In addition, different Cf genes have both similar and different roles in the disease resistance response, indicating that the disease resistance mechanism of Cf genes is complex. In this paper, progress in tomato leaf mold research was reviewed, and the regulatory mechanism underlying the Cf-mediated disease resistance response was thoroughly explored. We hope this summary will lay a foundation for research on tomato leaf mold disease resistance mechanisms and is applicable to breeding for disease resistance.

了解番茄叶霉病的抗性机制:综述

番茄叶霉病是番茄生产中的常见病害,严重影响番茄植株的生长发育、果实品质和产量。番茄叶霉病的研究历史悠久,主要集中在病原菌种群的分化、病原菌Avr基因产物的结构与功能、Cf抗性基因的克隆和抗病机制分析等方面。CfA​​vr之间的相互作用符合“基因对基因”假设和典型的Cf / Avr相互作用是效应物触发免疫 (ETI) 的一部分。然而,越来越多的研究证明,病原体相关分子模式(PAMP)触发的免疫(PTI)参与了Cf基因介导的抗病反应系统。此外,不同的Cf基因在抗病反应中的作用既相似又不同,说明Cf基因的抗病机制复杂。本文综述了番茄叶霉病的研究进展,并对Cf的调控机制进行了综述。介导的抗病反应得到了彻底的探索。希望本综述能为番茄叶霉病抗病机制研究奠定基础,并应用于抗病育种。
