Coordinated Shoot and Root Responses to Light Signaling in Arabidopsis

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 Arabidopsis. 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.
