Abstract

Rice germplasm collections contain vast reserves of genetic diversity but remain understudied. This Commentary highlights the effectiveness of mining genetic resources from germplasm as a means to overcome current yield constraints, using clustered-spikelet rice as an example.

发掘古老水稻种质,照亮改良新途径
这些发现意味着,对激素水平进行空间特异性控制可以有效地解除性状之间的相互依存关系,为未来的水稻品种在产量上实现突破提供了一条新途径。通过比较簇生辣椒和非簇生辣椒以及簇生玫瑰和非簇生玫瑰中的 BR 含量,观察到簇生和非簇生品种之间 BR 含量的波动类似于在水稻中观察到的情况。总之,本研究强调了从种质资源中挖掘基因资源作为克服当前作物产量限制的一种手段的有效性。这项研究范围广泛,从遗传分析到细胞学观察、化学诱变、基因克隆、基因组组装、分子机制分析、育种评估,甚至扩展到其他物种,为未来的种质探索提供了路线图。揭开 CL 的神秘面纱固然令人振奋,但我们期待着更多地利用作物种质资源来发现更多有价值的基因资源。人工智能和大数据时代加速了从野生稻到栽培稻的育种进程。
