Summary
Evidence is presented that there is a signalling pathway for UV-B (ultraviolet-B radiation) effects on gene activity that differs from that of the UV-A/blue light signalling pathway. Evidence is also presented for a specific UV-B receptor pigment, with peak sensitivity near 290 nm, which is active in growth regulation and induction of UV-protecting pigmentation. A possible chromophore in this photoreceptor is a tetrahydropterin derivative. There are many interactions between this UV-B photoreceptor and other photoreceptors in plants, and some of the effects mediated by the UV-B receptor may not take place via gene regulation. UV-B regulation of genes may also proceed via photon absorption in DNA. Various types of radiation-induced changes in DNA are discussed, and the conclusion drawn that the most important one is formation of (6-4) photoproducts of pyrimidine bases in DNA. Calculations show that stratospheric ozone depletion of realistic magnitude does not cause significant increase in excitation of the 290 nm UV-B photoreceptor, in contrast to photon absorption in DNA.
