一项在国内外从没报导过的、在水稻栽培历史上从没出现的技术—乳苗抛秧,在黑龙江省海林市由高级农艺师田宗丰研究、试验脱颖而出,去秋经有关专家考察,乳苗抛秧每公顷产量达
粒形对水稻产量形成具有重要决定作用,同时粒形还会影响稻米品质尤其是研磨与外观品质。本研究将粒形基因GS9与其它粒形基因GS3、GW5、GW7在同一遗传背景下进行两两聚合,研究GS9与其他粒形基因的聚合效应。同时在多个水稻高产品种中导入gs9等位基因,以探究gs9基因改良现有水稻品种粒形的育种价值。基于前期构建的日本晴背景的近等基因系NIL(gs9)、NIL(gs3)、NIL(GW5)、ML(GW7
水稻是世界上最重要的粮食作物之一,其产量的高低与其花的发育过程密切相关,因此,研究水稻颖花发育的分子机理已成为现代生命科学研究的重点和热点之一。近年来,随着对双子叶植物拟南芥花发育研究的深入,其成花诱导、花器官形成以及分化的分子遗传学机制有了较好的认识。但是,对单子叶植物水稻的花发育过程的分子机制认识还相对滞后。转录中介体复合物(Mediator complex, MED)是一种大分子蛋白复合物,
