Abstract
In the present work, UV-B-repressible and UV-B-inducible genes were identified in the pea, Pisum sativum L., by rapid amplification of 3′ cDNA ends through use of the polymerase chain reaction. Of the UV-B-repressible clones, psUVRub and psUVDeh represent genes encoding Rubisco activase and dehydrin, respectively. A third clone, psUVZinc, did not correspond closely in overall nucleotide sequence to any gene registered in GenBank; however, a short deduced peptide shared similarity with the photosystem-II reaction center X protein of the chlorophyll a+c-containing alga, Odontella sinensis. The UV-B-inducible clones, psUVGluc, psUVAux and psUVRib, were related to genes encoding β-1, 3-glucanase, auxin-repressed protein, and a 40S ribosomal protein, respectively. The modulation of these pea genes indicates how UV-B, through its actions as a physical stressor, affects several important physiological processes in plants.
