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.
