【文献解读】|NG-- A gene encoding maiz

背景:
multiple disease resistance (MDR)
A quantitative trait locus, qMdr9.02
SLB (causal agent Cochliobolusheterostrophus), GLS (causal agent Cercospora zeae-maydis) and NLB (causalagent Setosphaeria turcica)
结果:
ZmCCoAOMT2, which encodes a caffeoyl-CoAO-methyltransferase associated with the phenylpropanoid pathway and ligninproduction,conferring quantitative resistance to both southern leaf blight andgray leaf spot.
qMdr9.02位点对抗病性起作用的基因是ZmCCoAOMT2(GRMZM2G099363)。ZmCCoAOMT2基因编码咖啡酰辅酶A-O-甲基转移酶,该酶参与类苯基丙烷和脂氧合酶代谢途径,对木质素的合成有重要作用。ZmCCoAOMT2通过强化植物细胞壁,抑制植物细胞编程性死亡来实现抗病的效果。该基因氨基酸序列的差异导致了表达水平的多样性,最终造成了该位点在玉米品种中抗病性状的遗传多态性。

Fungal diseases are a major constraint tothe production of maize (Zea mays. L), one of the world’s most widely usedcrops.
