V. Chesnokov, Renate Manteuffel] Abstract : Low doses of UV-B irradiation applied to mature Nicotiana plumbaginifolia pollen grains stimulated pollen tube growth. The most pronounced effect was achieved after 1.5 min of irradiation. Using transgenic N. plumbaginifolia plants expressing the GFP reporter gene under the control of the seed-specific promoters USP (unknown seed protein) or LegB4 (legumin B4) genes, it was shown that these promoters are also inducible by UV-B irradiation of the pollen grains. The improvement of pollen viability and germination by UV-light is discussed with respect to effects on plant flowering and reproduction.
