Light effects on plants

Light effects on plants is a research topic within Plant Science. Science Explorer counts 25k research works in it since 1950. 9.9% of them reached the world's top 10% most cited for their field and year.

This cluster of papers focuses on the mechanisms and pathways involved in light signal transduction in plants, including the roles of photoreceptors such as phytochromes and cryptochromes, the regulation of plant development and growth by light, responses to UV-B radiation, and the application of optogenetics in studying plant signaling. Additionally, it explores the involvement of flavonoids and chloroplast movement in light-mediated processes.
