Plant architecture, which consists mainly of plant height, tillering, and panicle morphology, contributes greatly to grain yield in rice. Exploring the molecular mechanisms of rice plant architecture will provide theoretical guidance and valuable gene resources for breeding elite rice varieties with ideal plant architecture. In this review, we emphasize recent progress in elucidating the mechanisms that control rice plant architecture, focusing on tiller number, tiller angle, and panicle branching. Environmental factors influence the plasticity of rice plant architecture, and thus we also discuss the roles of environmental factors in regulating rice plant architecture.
