Different plant hormones contribute to maize reproductive success. Maize is a major crop species and significantly contributes directly and indirectly to human calorie uptake. Its success can be mainly attributed to its unisexual inflorescences, the tassel and the ear, whose formation is regulated by complex genetic and hormonal networks, and is influenced by environmental cues such as temperature, and nutrient and water availability. Traditional genetic analysis of classic developmental mutants, together with new molecular approaches, have shed light on many crucial aspects of maize reproductive development including the influence that phytohormones exert on key developmental steps leading to successful reproduction and seed yield. Here we will review both historical and recent findings concerning the main roles that phytohormones play in maize reproductive development, from the commitment to reproductive development to sexual reproduction.
不同的植物激素有助于玉米的生殖成功。玉米是一种主要的作物物种，直接和间接地对人类卡路里的摄取有显著贡献。它的成功主要归因于其单性花序，即雄穗和果穗，其形成受复杂的遗传和激素网络调控，并受到环境线索如温度、养分和水分供应的影响。对经典发育突变体的传统遗传分析，以及新的分子方法，揭示了许多关于玉米生殖发育的关键方面，包括植物激素对导致成功繁殖和种子产量的关键发育步骤的影响。在这里，我们将回顾植物激素在玉米生殖发育中所起的主要作用的历史和最新发现，从生殖发育的决定到有性生殖。
