顶端分生组织分裂成两个独立起作用的轴被定义为二分枝。这种类型的分枝通常发生在非维管束和非种子维管束植物中，而在种子植物中，它只在几个分类群中呈现初级生长形式。二分法是一个复杂的过程，它需要重新组织分生组织结构，并导致顶端几何形状和活性的变化。然而，控制重复顶端分裂的机制几乎不为人所知。在这里，我们概述了二叉分枝，发生在系统发育上遥远的植物的结构不同的顶端，以及不同的器官(例如，芽、根、根柄)。此外，还对二分法的形态发生效应进行了综述，包括它对器官发生和机械约束的影响。最后，讨论了二叉分枝的激素和遗传调控。
The division of the apical meristem into two independently functioning axes is defined as dichotomous branching. This type of branching typically occurs in non-vascular and non-seed vascular plants, whereas in seed plants it presents a primary growth form only in several taxa. Dichotomy is a complex process, which requires a re-organization of the meristem structure and causes changes in the apex geometry and activity. However, the mechanisms governing the repetitive apex divisions are hardly known. Here, an overview of dichotomous branching is presented, occurring in structurally different apices of phylogenetically distant plants, and in various organs (e.g., shoots, roots, rhizophores). Additionally, morphogenetic effects of dichotomy are reviewed, including its impact on organogenesis and mechanical constraints. At the end, the hormonal and genetic regulation of the dichotomous branching is discussed.
