Estimating the term…
The present invention relates to compounds according to general formula (I) with enhanced absorption of UV-B irradiation. The present invention also relates to an UV-B tolerant plant and a method for enhanced production of compounds according to general formula (I) in a plant or plant cell. Furthermore, the invention relates to a nucleic acid sequence SEQ-ID No. 1 encoding FPT2 catalyzing the production of compounds according to general formula (I). The invention further relates to compositions comprising compounds according to general formula (I). Furthermore, the invention relates to a method of conferring UV-B tolerance to a plant as well as an UV-B tolerant plant comprising the nucleic acid sequence SEQ-ID No. 1 encoding FPT2 catalyzing the production of compounds according to general formula (I).
A transgenic UV-B tolerant Arabidopsis plant cell, Arabidopsis plant tissue or Arabidopsis plant comprising an exogenous nucleic acid molecule consisting of the cDNA encoding a flavonol phenylacyltransferase 2 protein having at least 95% sequence identity to SEQ-ID NO:2, wherein said exogenous nucleic acid molecule has been introduced by genetic manipulation into a plant that does not naturally express said nucleic acid molecule, wherein said exogenous nucleic acid molecule is operably linked to a promoter, wherein said transgenic plant cell, plant tissue or plant has enhanced tolerance to UV-B irradiation relative to a native plant cell, plant tissue or plant of the same species that does not naturally express said nucleic acid molecule, and wherein said enhanced UV-B tolerance is assessed after UV-B irradiation treatment for at least 2 hours per day for 28 days with 2000 mW/m2.
