Abstract
NPR1 is a key transcriptional coregulator in plant defense responses. In this issue, Spoel et al. (2009) demonstrate that proteasome-mediated degradation of NPR1 in the nucleus promotes efficient expression of defense response genes following infection and prevents spurious activation of defensive responses in the absence of infection.
摘要
NPR1是植物防御反应中的关键转录共调节因子。在本期中，斯波尔等人（2009年）证明，蛋白酶体介导的细胞核内NPR1降解促进感染后防御反应基因的有效表达，并防止在未感染时防御反应的错误激活。
