摘要： Trichome is a specialized structure differentiated during the morphogenesis of plant leaf epidermal cells. In recent years, with the continuous researches on trichome development of Arabidopsis and other plants, more and more genes related to trichome morphogenesis have been discovered, including R2R3-type MYB genes. In this study, we cloned a R2R3-type MYB family gene from grape, VvMYB114, a target gene of vvi-miR828. qRT-PCR showed that VvMYB114 mRNA accumulated during grape fruit ripening, and VvMYB114 protein had transcriptional activation activity. Heterologous overexpression of VvMYB114 in Arabidopsis reduced the number of trichome on leaves and stems. Mutating the miR828-binding site in VvMYB114 without altering amino-acid sequence had no effect on trichome development in Arabidopsis. The results showed a different role of the regulation of miR828 to VvMYB114 in Arabidopsis from in grape, which indicated the functional divergence of miRNA targeting homoeologous genes in different species played an important roles in evolution and useful trait selection.
