摘要: 株高(PH)是植物表型的重要组成部分可以影响植物生物量、产量、抗倒伏能力和机械化水平。由于许多调控植物生长和发育的复杂途径仍然知之甚少,我们仍然无法仅通过育种途径来获得理想的植物株型。植物高度受自身的基因型、植物激素、环境条件与其他植物互作的影响。本文综述了影响植株高度的几个关键因素,包括调控株高的发育过程、控制株高的遗传背景和位点以及激素调控株高的分子机制,并重点讨论了嫁接对植物株高表型以及遗传水平的分子调控机制。最后,我们提出了如何将最新发现更好的应用于株高育种的策略,并提出了植物株高未来研究的潜在方向。

Abstract:

Plant height (PH) is one of the most important components of the plant ideotype, and it affects plant biomass, yield, lodging resistance, and the ability to use mechanized harvesting.  Since many complex pathways controlling plant growth and development remain poorly understood, we are still unable to obtain the most ideal plants solely through breeding efforts.  PH can be influenced by genotype, plant hormonal regulation, environmental conditions, and interactions with other plants.  Here, we comprehensively review the factors influencing PH, including the regulation of PH-related developmental processes, the genetics and QTLs contributing to PH, and the hormone-regulated molecular mechanisms for PH.  Additionally, the symbiotic influence of grafting on PH is discussed, focusing on the molecular regulation of gene expression and genetics.  Finally, we propose strategies for applying recent findings to breeding for better PH, highlight some knowledge gaps, and suggest potential directions for future studies.
