Flowers contain the male and female sexual organs that are critical for plant reproduction and survival. Each individual flower is produced from a floral meristem that arises on the flank of the shoot apical meristem and consists of four organ types: sepals, petals, stamens, and carpels. Because floral meristems contain a transient stem-cell pool that generates a small number of organs composed of a limited number of cell types, they are excellent model systems for studying stem-cell maintenance and termination, cell fate specification, organ morphogenesis, and pattern formation.
花包含对植物繁殖和生存至关重要的雄性和雌性生殖器官。每一朵花都是由一个花分生组织产生的，该花分生组织出现在茎尖分生组织的侧面，由四种器官类型组成：萼片、花瓣、雄蕊和心皮。由于花分生组织包含一个短暂的干细胞库，该干细胞库产生少量由有限数量的细胞类型组成的器官，因此它们是研究干细胞维持和终止、细胞命运特化、器官形态发生和模式形成的优秀模型系统。
