[Subcellular localization and resistance to Botrytis cinerea of a new type lipid transfer protein AtDhyPRP1 from Arabidopsis thaliana].
Genetic transformation was adopted to analyze the subcellular localization and the resistance to fungal pathogens of Arabidopsis lipid transfer protein AtDHyPRP1. The coding sequence of AtDHyPRP1 amplified by PCR from Ws ecotype was used to construct the plant binary expression vector pRI101-AN-AtDHyPRP1 and the fusion expression vector pCAMBIA1302-AtDHyPRP1-GFP. Transgenic tobacco and Arabidopsis plants were produced by leaf disc and floral dip protocols, respectively. AtDHyPRP1 could improve the resistance of tobacco to Botrytis cinerea remarkably and the infection sites on transgenic tobacco leaves accumulated large amounts of H2O2. Observation under laser scanning confocal microscope showed that AtDHyPRP1 was localized to cell surface. It suggested that AtDHyPRP1 might play special function after secretion to outside of the cell and was involved in plant defense system against pathogens.
