Branching angles in the modulation of plant architecture: Molecular mechanisms, dynamic regulation, and evolution.

ABSTRACT: Plants develop branches to expand areas for assimilation and reproduction. Branching angles coordinate with branching types, creating diverse plant shapes that are adapted to various environments. Two types of branching angle-the angle between shoots and the angle in relation to gravity or the gravitropic set-point angle (GSA) along shoots-determine the spacing between shoots and the shape of the aboveground plant parts. However, it remains unclear how these branching angles are modulated throughout shoot development and how they interact with other factors that contribute to plant architecture. In this review, we systematically focus on the molecular mechanisms that regulate branching angles across various species, including gravitropism, anti-gravitropic offset, phototropism, and other r
