Involvement of the Light Signalling Components HY5 and BIC1,2 and SPA1 in Plant Responses to Elevated Daytime UV-B Doses.

Abstract excerpt

Plants respond to ultraviolet B radiation (280-320 nm) with an integrated reaction that includes the reception of the acting stress factor, followed by the generation of reactive oxygen species and damage to macromolecules and membrane structures, as well as changes in cellular metabolism and the formation of protective systems. However, the involvement of key UV-B-related signalling components such as HY5, SPA1...
