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.
