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:英文名稱:Corn northern leaf blight (northern corn leaf blight (NCLB)), also
known as Turcicum leaf blight (Exserohilum turcicum),又稱玉米條斑病、玉米煤紋病烘浦、玉米斑病抖坪、玉米枯葉病。
Corn southern leaf blight玉米小斑病: 玉米小斑病又稱玉米斑點病闷叉，是由半知菌亞門絲孢綱絲孢目長蠕孢菌侵染所引起的一種真菌病害.
結(jié)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.
