(Pst) is a devastating biotrophic fungal pathogen that causes wheat stripe rust. It usually loves cool and moist places and can cause 100% crop yield losses in a single field when ideal conditions for disease incidence prevails. Billions of dollars are lost due to fungicide application to reduce stripe rust damage worldwide. is a macrocyclic, heteroecious fungus that requires primary (wheat or grasses) as well as secondary host ( or spp.) for completion of life cycle. In this review, we have summarized the knowledge about pathogen life cycle, genes responsible for stripe rust resistance, and susceptibility in wheat. In the end, we discussed the importance of conventional and modern breeding tools for the development of -resistant wheat varieties. According to our findings, genetic engineering and genome editing are less explored tools for the development of -resistant wheat varieties; hence, we highlighted the putative use of advanced genome-modifying tools, i.e., base editing and prime editing, for the development of -resistant wheat.
条锈菌(Pst)是一种具有毁灭性的活体营养型真菌病原体,可引发小麦条锈病。它通常喜好凉爽潮湿的环境,当病害发生的理想条件具备时,在单个田块中可导致作物产量损失达100%。在全球范围内,为减少条锈病危害而施用杀真菌剂造成了数十亿美元的损失。条锈菌是一种大型异宗寄生真菌,其生命周期的完成需要初级寄主(小麦或禾本科植物)以及次级寄主(小檗属或十大功劳属物种)。在本综述中,我们总结了有关该病原体生命周期、小麦中负责抗条锈病和感病性的基因的知识。最后,我们讨论了传统和现代育种工具在培育抗条锈菌小麦品种方面的重要性。根据我们的研究结果,基因工程和基因组编辑在培育抗条锈菌小麦品种方面是较少被探索的工具;因此,我们强调了先进的基因组修饰工具,即碱基编辑和引导编辑在培育抗条锈菌小麦方面的潜在用途。
