Phytophthora root and stem rot of soybean [Glycine max (L.) Merr.],caused by Phytophthora sojae Kaufmann and Gerdemann,is a destructive disease throughout the soybean planting regions in the world.Here,we report insights into the function and underlying mechanisms of a novel ethylene response factor (ERF) in soybean,namely GmERF5,in host responses to P sojae.GmERF5-overexpressing transgenic soybean exhibited significantly enhanced resistance to P sojae and positively regulated the expression of the PR1 0,PR1-1,and PR1 0-1 genes.

植物受到环境胁迫时,可以迅速合成并积累不同种类的渗透调节物质来维持植物细胞内正常的生理机能,避免植物受到胁迫伤害,棉子糖系列寡糖(RFOs)即为一种小分子渗透调节物质。正常生长条件下,棉子糖系列寡糖在植物体内积累量相对较少,而受到外界的胁迫时,其含量会迅速增加。肌醇半乳糖苷合成酶(Galactinol synthase,GolS)是棉子糖合成过程中的关键酶,是植物应对环境胁迫的关键基因。木薯作为一

稻米垩白形状是受多基因控制的、复杂的数量性状,目前有关垩白性状QTL基因已成功克隆的研究报道不多.为稻米垩白性状QTL精细定位克隆提供新素材,本研究以150个V20B/CPSLO17重组自交家系(RIL)为作图群体,并以8602个SLAF标签构建的全基因高密度分子连锁图谱(总图距为2508.65 cM,标记间平均距离为0.292 cM)为基础,再结合RIL群体的稻米垩白度表型数据,运用MapQTL

Little progress has been made in the genetic analysis of drought tolerance,because it is a complex trait controlled by a number of genes and affected by various environmental factors.In here,we screen
大豆胞囊线虫病是世界性大豆病害，其可对大豆造成严重的产量损失。培育抗性品种是防治该病害的最有效措施之一。本研究的主要目的之一是探索栽培大豆及其农家品种对胞囊线虫病3号和4号生理小种的抗性遗传基础。一共有440份大豆农家品种及育成品种进行表型鉴定，结果表明共有131份新抗源被发现；这440份供试品种通过SLAF-seq测序技术进行SNP分型，在MAF＞5％的条件下共获得的35760个SNP标记。关联
大豆是我国重要的粮食作物，其含丰富的植物蛋白，营养价值丰富，利于人们的身体健康。但把分子辅助育种直接用于育种实践还存在实际难度，尽管已定位的大豆蛋白质含量相关QTL数目比较多，但由于数量性状很容易受到外界环境的影响，很难发掘出多环境下的稳定位点。在大多数研究中，图谱标记较少，密度不够，定位出的QTL标记区间比较大，不能获得真实有效的位点。大豆蛋白质含量是由多基因控制的数量性状，大部分基因都是微效作
外界微生物在侵染植物的时候，能够刺激植物产生过敏性反应(HR)以及其他的生理生化变化.HIR基因能够参与众多的生理生化反应，比如调节离子通道、调节细胞周期等，并与过敏性反应(HR)相关.但是在大豆中HIR基因在根瘤共生过程中的作用尚不明确.为了研究HIR基因在受到根瘤菌侵染时的作用，本研究通过对大豆基因组HIR相关同源基因进行预测，并且进行生物信息学的相关分析.最后，对绥农14接种寒地根瘤菌HD0
Soybean protein concentration is an important trait driver of successful soybean quality.Due to its complex nature,less stable quantitative trait loci were known.The goal of this study was to identify
