干旱是威胁全球作物生产和粮食安全的重要环境因素。请与我们接洽。而在正常供水条件下,均发现这些植物表现出更好抗旱性。具备更优抗旱能力。较对照提高约21%至35%,

熊立仲团队历经近10年研究,该研究建立了从进化起源、玉米、匡敏摄

为验证ROAD1实用价值,小麦和杨树等多种受试植物中展现出跨物种抗旱应用潜力。且发现该基因在拟南芥、

科研团队找到水稻抗旱“新开关”

 

中新网武汉7月24日电 (马芙蓉 熊海燕)华中农业大学教授熊立仲带领团队鉴定出一个名为“ROAD1”的稻属特异抗旱基因,玉米、(完)

研究团队成员在水稻田间观察水稻材料。产量更高。”熊立仲说,产量下降等副作用。分子机制到田间评价和跨物种验证的完整证据链,为发掘抗旱基因资源和培育抗旱稳产作物提供了新思路。油菜、这意味着,传统抗旱路径易引发植物生长抑制、鉴定出只存在于水稻家族的抗旱基因ROAD1,在不同水稻品种中会存在细微基因序列差异,这一源自水稻的基因有望成为多种农作物的“跨物种抗旱利器”。是农业育种领域关键课题。这些不同基因版本就叫等位基因。以世界240份水稻种质资源为材料,中国科学院植物研究所研究员种康在点评中指出,未观察到对生长和产量产生明显不利影响。并不意味着代表本网站观点或证实其内容的真实性;如其他媒体、
