- 摘要:
- 植物茎尖（SAM）和根尖分生组织（RAM）分别是调控植物地上与地下部分发育的核心。SAM负责形成叶、枝、花、果等地上器官，直接影响作物产量；而RAM参与根系构建与水分养分吸收，决定作物抗逆性和生物量积累。研究顶端分生组织的发育对作物品质改良和产量提升具有重要意义。该研究对二者的结构与功能、调控机制和影响因素等方面进行了综述，总结现阶段存在的问题，并对未来研究方向进行展望，以期为深入解析植物发育的核心调控机制，并指导高产、抗逆作物新品种的选育实践提供参考依据。
- Abstract:
- The shoot apical meristem (SAM) and root apical meristem (RAM) are central regulators of aerial and underground plant development,respectively.SAM drives the formation of leaves,branches,flowers,and fruits,directly affecting crop yield.RAM supports root system architecture and nutrient uptake,influencing stress tolerance and biomass.Thus,studying SAM and RAM development is crucial for crop improvement.This study outlined their structure and function,regulatory mechanisms,influencing factors,current challenges,and future research directions，with the aim of providing insights into the core regulatory mechanisms of plant development and offering guidance for the breeding of high-yield,stress-resistant crop varieties.
