Light participates in the auxin-dependent regulation of plant growth

Bingsheng Lv et al. J Integr Plant Biol. 2021 May.

Abstract

Light is the energy source for plant photosynthesis and influences plant growth and development. Through multiple photoreceptors, plant interprets light signals through various downstream phytohormones such as auxin. Recently, Chen et al. (2020) uncover a new layer of regulation in IPyA pathway of auxin biosynthesis by light. Here we highlight recent studies about how light controls plant growth through regulating auxin biosynthesis and signaling.

Keywords: auxin biosynthesis and signaling; light; plant growth; shade avoidance syndrome.
