Intraspecific Difference in Plant Response to UV-B Radiation and Its Mechanism

Researches on UV-B radiation are generalized,especially those on response of plant to UV-B radiation.Under supplementary UV-B radiation,response diversifies within a certain species of plants.The difference may exist in plant development,morphostructure,physiological biochemistry and ultraviolet B absorbing compounds.The mechanism for formation of the differences is also discussed on DNA basis,which may provide some theoretic bases for future research on plant protection.
