Salinity is a major abiotic stress that threatens crop yield and food supply in saline soil areas. Wheat (Triticum aestivum L.) is the most important cereal crop in arid and semiarid land areas, which ...

这项研究对六倍体小麦属(Triticum)不同基因组组成的重组事件进行了精妙比较。通过分析普通小麦(T. aestivum)与斯佩尔特小麦(T. spelta)、人工合成种T. kiharae的杂交后代，发现B基因组染色体(特别是4B和7B)上，斯佩尔特小麦的染色体片段通常比人工合成种更长。

推荐 为解决小麦种植密度增加导致的倒伏和光照利用效率低等问题，英国洛桑研究所等机构研究人员利用EMS诱变和正向遗传学筛选，获得了BRI1基因功能减弱或丧失的小麦突变体。结果显示，这些突变体具有更直立的叶片角度和半矮化特性，有助于提高高密度种植条件下的产量潜力。该研究为小麦遗传改良提供了新的基因资源，对作物育种具有重要意义。

Wheat (Triticum aestivum) is one of the most cultivated cereal crops worldwide and is a major source of protein and carbohydrates to humans. Nevertheless, like all the crops, it is faced with various ...

小麦能够成为早期酿酒的主角，主要在于它是由淀粉、蛋白质、酶类等成分构成，这是发酵的原料基础；原料中的淀粉质不能直接被酵母利用、代谢生成酒精，这时则需要经过糊化、糖化后，依赖酶的核心作用，将淀粉高效转化为可发酵糖；蛋白质虽不直接参与酒精发酵，但却是培育 ...
