Salicylic acid (SA) is one of the key signal molecules in regulating plant resistance to diverse pathogens.The effect of SA on the defense efficiency of wheat against fusarium head blight (FHB) and its causal agent, Fusarium graminearum (Fg), are still poorly understood.

小麦赤霉病是小麦的一种真菌病害,严重威胁着小麦的产量和品质.本研究利用GeneCalling技术,在小麦赤霉病抗性品种宁7840中克隆到一个与小麦赤霉病抗性相关的基因,定名为TaRGA5.该基因ORF全长2781bp,编码929个氨基酸,含有一个NB-ARC-LRR功能域.
小麦赤霉病(Fusarium Head Blight,FHB)是由禾谷镰刀菌(F.graminearum,F.g)引起的小麦的一种主要穗部病害,主要发生在湿润和半湿润地区.赤霉病不仅造成产量降低,而且其分泌的真菌毒素在小麦籽粒中积累导致品质下降,严重的可引发人畜中毒.
Circadian clock has been found to play important roles in plant growth and development.Wheat (Triticum astivum L.) circadian clock genes, TaTOC1-A, TaTOC1-B, TaTOC1-D, were cloned and mapped in wheat

α-醇溶蛋白是小麦种子中含量最高的醇溶蛋白,同时也是引起人体乳糜泻病的主要蛋白.本实验以来源于小麦近缘种栽培一粒小麦(AA)、拟斯卑尔脱山羊草(SS)、粗山羊草(DD)材料DNA为模板,用小麦种子醇溶蛋白保守引物进行PCR扩增,共获得23个α-醇溶蛋白基因,GenBank登录号分别为:KC421073-KC421095,编码279-318个氨基酸.
Salicylic acid (SA) plays a critical role in defense against pathogens.SA is predominantly associated with resistance against biotrophic and hemibiotrophic pathogens, and with triggering systemic acqu
