Floral patterning is a complex task. Various organs and tissues must be formed to fulfill reproductive functions. Flower development has been studied, mainly looking for master regulators. However, downstream changes such as the cell wall composition are relevant since they allow cells to divide, differentiate, and grow. In this review, we focus on the main components of the primary cell wall-cellulose, hemicellulose, and pectins-to describe how enzymes involved in the biosynthesis, modifications, and degradation of cell wall components are related to the formation of the floral organs. Additionally, internal and external stimuli participate in the genetic regulation that modulates the activity of cell wall remodeling proteins.
花部形态建成是一项复杂的任务。为了完成生殖功能，各种器官和组织必须形成。花的发育一直是研究的主要对象，主要是寻找主控因子。然而，细胞壁组成等下游变化也很重要，因为它们使细胞能够分裂、分化和生长。在这篇综述中，我们重点介绍初生细胞壁的主要成分——纤维素、半纤维素和果胶，描述参与细胞壁成分生物合成、修饰和降解的酶与花器官形成的关系。此外，内部和外部刺激参与调节细胞壁重塑蛋白活性的遗传调控。
