Application of 9LOX protein and coding gene thereof in regulation and control of wheat disease resistance

The invention discloses an application of 9LOX protein and a coding gene thereof in regulation and control of wheat disease resistance. According to the application disclosed by the invention, firstly, the stripe rust resistance of 9LOX-4a and 9LOX-4b mutant materials, a 9LOX-4a4b double mutant material and a wild type Kronos material is analyzed to find that 9LOX can regulate and control the stripe rust resistance of wheat. Further, overexpression of 9LOX in a wild type Kronos material finds that overexpression of 9LOX can reduce the resistance of wheat to stripe rust. The 9LOX protein and related biological materials thereof play an important role in cultivating disease-resistant wheat varieties. 本发明公开了9LOX蛋白及其编码基因在调控小麦抗病性中的应用。本发明首先通过对9LOX-4a、9LOX-4b突变体材料及9LOX-4a4b双突变体材料和野生型Kronos材料的抗条锈病能力进行分析发现，9LOX可以调控小麦条锈病抗性。进一步通过在野生型Kronos材料中过表达9LOX发现，过表达9LOX可以降低小麦对条锈病的抗性。9LOX蛋白及其相关生物材料将在培育抗病小麦品种中发挥重要的作用。
