The spectacular yield increases in rice and wheat during the green revolution were partly realized by reduced gibberellin (GA) synthesis or sensitivity, both causing the accumulation of DELLA proteins. Although insights into the regulation of plant growth and development by DELLA proteins advanced rapidly in arabidopsis (Arabidopsis thaliana), DELLA-mediated regulation of downstream responses in cereals has received little attention to date. Furthermore, translating this research from arabidopsis to cereals is challenging given their different growth patterns and our phylogenetic analysis which reveals that DELLA-related DGLLA proteins exist in cereals but not in arabidopsis. Therefore, understanding the molecular basis of DELLA function in cereals holds great potential to improve yield. In this review, we propose to extend the focus of DELLA functional research to cereals, and highlight the appropriate tools that are now available to achieve this.

绿色革命期间水稻和小麦单产显着提高，部分原因是赤霉素（GA）合成或敏感性降低，均导致DELLA蛋白积聚。尽管关于通过DELLA蛋白调节植物生长和发育的见解在拟南芥（拟南芥（Arabidopsis thaliana）），迄今为止，DELLA介导的谷物下游响应的调控鲜为人知。此外，鉴于其不同的生长方式以及我们的系统发育分析，将这项研究从拟南芥转化为谷类食品具有挑战性，这表明在谷物中存在与DELLA相关的DGLLA蛋白，而在拟南芥中不存在。因此，了解DELLA在谷物中功能的分子基础具有提高产量的巨大潜力。在这篇评论中，我们建议将DELLA功能研究的重点扩展到谷类食品，并着重介绍目前可用的适当工具来实现这一目标。
