Improvement of plant tolerance to drought stress by cotton tubby-like protein 30 through stomatal movement regulation
棉花 气孔运动 GhTULP30 干旱胁迫
font style='font-size:12px;'>
2024/4/16
棉花是一种重要的工业作物，逐渐转向在干旱地区种植。然而，参与植物响应各种胁迫的Tubby-like protein，TULP在棉花中很少被报道。本研究通过调节气孔运动，展示了GhTULP30对植物耐受干旱胁迫的改进。GhTULP30在酵母中的异源表达显著提高了其抗盐和干旱耐受性。GhTULP30的过表达使得拟南芥种子在种子萌发期间更加抵御干旱和盐胁迫，并且在干旱胁迫条件下提高了该植物的气孔关闭速度...

该研究发现棉花种植环节的环境影响取决于灌溉、农药和化肥用量。全球约有一半的棉田使用地下水灌溉，农药平均施用量为 1.57 kg/ha，氮磷肥平均投入量为150 kg/ha。全球各棉区灌溉、农药、氮肥施用量差异较大，经济发展水平高的地区施用量较高，而经济水平和水资源有限的棉区施用量较少，亟需因地制宜提高灌溉用水、化肥、农药利用效率，减少生产环节的环境影响。研究还发现，除了棉花种植环节对环境的影响外，...

栽培陆地棉 纤维品质 优异位点 分子育种
font style='font-size:12px;'>
2024/4/16
栽培陆地棉广泛种植于世界各地，是最重要的天然纤维来源，纤维品质直接决定了其经济价值。国内外棉花育种家开展了广泛的远缘杂交工作，将许多稀有的重要基因转移到栽培陆地棉中提高纤维品质，但并未对这些基因进行深入研究。本研究分析了超过3000份棉花种质资源，总计调查了近80000个纤维品质数据，全面剖析和评估了现存陆地棉种质资源中纤维品质相关的优异位点，并从远缘杂交渐渗系中鉴定到两个新的与纤维品质密切关联的...
