Light is one of the most important environmental signals and regulates many biological processes in plants. Studies on light-regulated development have mainly focused on aspects of shoot growth, such as de-etiolation, cotyledon opening, inhibition of hypocotyl elongation, flowering, and anthocyanin accumulation. However, recent studies have demonstrated that light is also involved in regulating root growth and development in . In this review, we summarize the progress in understanding how shoots and roots coordinate their responses to light through different light-signaling components and pathways, including the COP1 (CONSTITUTIVELY PHOTOMORPHOGENIC 1), HY5 (ELONGATED HYPOCOTYL 5), and MYB73/MYB77 (MYB DOMAIN PROTEIN 73/77) pathways.
光是最重要的环境信号之一，调节着植物中的许多生物过程。对光调控发育的研究主要集中在芽生长的各个方面，如脱黄化、子叶张开、抑制下胚轴伸长、开花和花色素苷积累。然而，最近的研究表明，光也参与调节在 中的根生长和发育。在这篇综述中，我们总结了如何通过不同的光信号成分和途径（包括 COP1（CONSTITUTIVELY PHOTOMORPHOGENIC 1）、HY5（ELONGATED HYPOCOTYL 5）和 MYB73/MYB77（MYB DOMAIN PROTEIN 73/77）途径）理解茎和根如何协调对光的反应。
