[Abstract]  

Phytophthora infestans is a hemibiotroph oomycete that primarily infects potato and tomato. It infects stems, leaves, and tubers and fruits of potato and tomato. High throughput and reproducible infection assays are prerequisites to find sources of resistance in any crop. In this protocol, we describe a detached leaf assay (DLA) for conducting the virulence assay of P. infestans in potato leaves. A late blight infection assay using a potato detached leaf is a semi-high throughput assay in which hundreds of plants can be screened in a laboratory setting.

[摘要]  [摘要]疫霉菌是一种主要感染马铃薯和番茄的半生营养菌卵菌。它感染马铃薯和番茄的茎,叶,块茎和果实。高通量和可重复的感染测定是寻找任何农作物抗药性来源的先决条件。在此协议中,我们描述了分离叶分析(DLA),用于进行马铃薯叶中致病疫霉的毒力测定。使用马铃薯离体叶的晚疫病感染测定是一种半高通量测定,其中可以在实验室环境中筛选数百种植物。

[背景]就食品和营养价值而言,马铃薯(Solanum tuberosum L.)是最重要的非谷物粮食作物之一(Zhang等人,2017)。晚疫病引起卵菌病原体马铃薯的晚疫病菌是世界上最具破坏性的马铃薯的疾病之一,是在马铃薯生产中最重要的产量限制因素(Haverkort等人,2008和2016 ;费舍尔等人, 2012 )。后期抗白叶枯病的育种被认为是抗击这种疾病的重要因素。为此,在可用种质中鉴定新的抗性来源是至关重要的一步。已经开发了几种测试方法,例如田间测试,整株植物测定和离体叶片测定(DLA)。DLA提供的感染增加,并且马铃薯叶表现出对疫病菌的敏感性高于田间和整个植物的检测方法(Stewart ,1990 ;Vleeshouwers等,1999 ...
