The plant ovule is a fundamentally important organ that is the direct progenitor of the seed. It is one of the last structures to form in the flower and contains relatively few tissues, but undergoes complex developmental transitions that are essential for reproduction. Ovule number and flower fertility are important factors influencing yield, yet studies have identified challenges in trying to increase one without compromising the other. Recent findings in Arabidopsis and cereal crops highlight regulatory pathways that contribute to this yield constraint. Here, we consider the basis for variation in ovule number and development, with a particular focus on hormones and transcriptional regulators that constitute promising targets for the optimisation of reproductive traits and yield.

建立植物发育过程中胚珠数量和功能的监管蓝图。

植物胚珠是基本重要的器官,是种子的直接祖先。它是花中最后形成的结构之一,包含相对较少的组织,但经历了对繁殖至关重要的复杂发育转变。胚珠数和花朵生育力是影响产量的重要因素,但研究已经确定了在不影响另一个的情况下试图增加其中一个的挑战。最近在拟南芥和谷类作物中的发现突出了导致这种产量限制的调控途径。在这里,我们考虑了胚珠数量和发育变异的基础,特别关注激素和转录调节因子,它们构成了优化生殖性状和产量的有希望的目标。
