摘要

The gene-for-gene relationship of host–pathogen interaction explained by H. H. Flor in mid of the 20th century set a milestone in understanding the biochemical and genetic basis of plant diseases and several components involved in plant–pathogen interactions. It highlighted the importance of accomplishing differential sets and understanding the pathogen population structure, it further led to theidentification and cloning of several resistance ( R ) genes in plants. These R genes have been deployed and altered for fighting against diseases in a large number of crops using various conventional approaches and biotechnological tools. Identification of R genes and their corresponding Avr genes in many cases played a significant role in understanding of R-Avr gene interactions. Rapid cloning of R genes and editing of susceptible R genes are the other avenues that have broadened the horizon of utilizing R genes in crop improvement programmes. Further, combining R genes with quantitative disease resistance genes has paved the way to develop durable resistance in cultivars. Therecent advances in genetics, genomics, bioinformatics and other OMICS tools are now providing greater prospects for deeper understanding of host–pathogen interaction.

H.Flan在20世纪中叶解释的宿主病原体相互作用的基因与基因关系在理解植物疾病的生化和遗传基础和植物病原体相互作用中的几个成分中的一个里程碑。它强调了实现差异集和了解病原体种群结构的重要性,进一步导致了植物中几种阻力(R)基因的identification和克隆。这些R基因已经部署并改变了使用各种传统方法和生物技术工具对大量作物中的疾病进行斗争。许多情况下,R基因的鉴定及其相应的AVR基因在理解R-AVR基因相互作用方面发挥了重要作用。 R基因的快速克隆和对易感R基因的编辑是其他途径,这些途径已经扩大了在农作物改善计划中使用R基因的地平线。此外,将R基因与定量疾病抗性基因组合已经铺平了在栽培品种中发育耐用性的方式。遗传学,基因组学,生物信息化学和其他OMICS工具的遗传学进展现在正在为更深入的了解宿主病原体相互作用提供更大的前景。
