Wheat is one of the most important cereal crops, and it is essential for worldwide food security. However, wheat production is threatened by various diseases, including wheat stripe rust caused by the fungus Puccinia striiformis f. sp. tritici (Pst). The development of plant resistance against disease is usually challenged by potential reduction in crop yield due to the enhancement of plant immunity. In a recent article, Wang et al. found that TaPsIPK1 is a susceptibility gene targeted by rust effectors. Editing of TaPsIPK1 increases resistance to stripe rust without any developmental effects or yield penalty, providing an exceptional resource for developing disease resistance in wheat.
小麦是最重要的谷类作物之一，对全球粮食安全至关重要。然而，小麦生产受到各种病害的威胁，包括由真菌条形柄锈菌小麦专化型（Pst）引起的小麦条锈病。植物抗病性的发展通常受到挑战，因为植物免疫力增强可能导致作物产量下降。在最近的一篇文章中，王等人发现TaPsIPK1是锈菌效应子靶向的感病基因。编辑TaPsIPK1可增强对条锈病的抗性，且无任何发育影响或产量损失，为培育小麦抗病性提供了独特资源。
