【文献解读】|PBJ--The durable wheat di

背景：

The wheat gene Lr34 provides durable andpartial field resistance against multiple fungal diseases of wheat, includingthree wheat rust pathogens and wheat powdery mildew.The Lr34 resistance is encoded by a rare variant of anATP-binding cassette (ABC) transporterthat evolved after wheat domestication.

Lr34(=Yr18/Sr57/Pm38), Lr67(=Yr46/Sr55/Pm46) and Lr46 (=Yr29/Sr58/Pm39),

hemi-biotrophic fungal disease northerncorn leaf blight (NCLB), also known as Turcicum

leaf blight (Exserohilum turcicum)

maize common rust disease caused by thebiotrophic fungusPuccinia sorghi

leaf tip necrosis (LTN)

玉米大斑病:英文名称:Corn northern leaf blight (northern corn leaf blight (NCLB)), also

known as Turcicum leaf blight (Exserohilum turcicum),又称玉米条斑病、玉米煤纹病、玉米斑病、玉米枯叶病。

Corn southern leaf blight玉米小斑病: 玉米小斑病又称玉米斑点病，是由半知菌亚门丝孢纲丝孢目长蠕孢菌侵染所引起的一种真菌病害.

结果：

Transform the Lr34 resistance gene into themaize hybrid Hi-II. Lr34-expressing maize plants showed increased resistanceagainst the biotrophic fungal disease common rust and the hemi-biotrophicdisease northern corn leaf blight.
