Ornamental plants can generate higher economic value per unit area compared with traditional crops. Enhancing market share in the flower industry relies on cultivating varieties with exceptional ornamental traits. Petal size, a critical factor influencing flower shape and ornamental appeal, is a primary focus for horticultural breeding selection. In this article, we review recent advances in understanding the regulation of petal size in ornamental plants through analyzing various patterns of cell division and expansion underlying petal growth and the genes involved in the related regulatory paradigms. We further highlight the intricate network of petal size control affected by multiple phytohormones and discuss several open questions and strategies for breeding ornamental plants with desired petal size traits based on current findings.
与传统作物相比，观赏植物每单位面积能产生更高的经济价值。提高花卉产业的市场份额依赖于培育具有卓越观赏特性的品种。花瓣大小是影响花形和观赏吸引力的关键因素，是园艺育种选择的主要关注点。在本文中，我们通过分析花瓣生长过程中细胞分裂和扩展的各种模式以及相关调控范式中涉及的基因，综述了观赏植物花瓣大小调控研究的最新进展。我们进一步强调了多种植物激素影响下的花瓣大小控制复杂网络，并根据当前研究结果讨论了几个开放性问题以及培育具有理想花瓣大小性状观赏植物的策略。
