Abstract
UV-B induces gene expression in plants, which is a vital protective response. However, little is known about the mechanisms of UV-B perception and signal transduction, in contrast to other organisms. We have studied in detail the UV-B induction of the gene encoding chalcone synthase in Arabidopsis cells and gained initial information of the novel UV-B signal transduction pathway involved. The aim is to test the hypotheses we have developed. We will: (1) Identify directly plasma membrane processes initiated by UV-B; (2) determine whether an NADPH oxidase is involved in UV-B signal transduction; (3) investigate the involvement of particular cellular calcium pools in UV-B signal transduction using targeted aequorin fusions; and (4) test whether a calmodulin stimulated Ca2+ ATPase is involved in the UV-B signalling pathway.
