Molecular aspects of Arabidopsis nonhost resistance to Phakopsora pachyrhizi

, 2014
Arabidopsis expresses nonhost resistance (NHR) to Phakopsora pachyrhizi, the causal agent of Asian soybean rust disease that threatens worldwide soybean cultivation. Nonhost resistance is durable and effective to a broad spectrum of pathogens. Understanding nonhost immunity at the molecular level would likely provide knowledge one could use to make ...
