LRK10L-2 is known to be related to the plant disease response, little information is available about the relationship of LRK10L-2 and fruit ripening. The protein physicochemical properties, conserved domains, gene structures, subcellular locali- zation, expression patterns during grape fruit development and promoter activity of the members of grape LRK10L-2 gene family were explored in this study. A total of 109 LRK10L-2 family gene members were identified, and mainly distributed on chromosome 16. Almost all of them were located in the plasma membrane. Most of the LRK10L-2 genes contain four or five motifs, ranging from 0 to 5 introns and have the cis-acting elements related to hormones in their promoter regions. There were 20 pairs of tandem duplicates and 293 pairs of segmental duplication in LRK10L-2 family genes.?It was proved that the expression of LRK10L-2 gene varied at the different fruit development stages of 'Kyoho' and its early-ripening bud mutant, ‘Fengzao’. The subcellular localization of VIT_16s0098g00160 and VIT_16s0098g00400?were in the plasma membrane, and had a significant enrichment of the GUS signal in N.benthamiana leaves for the promoter. The results lay a solid basis for the further functional researches of the LRK10L-2 genes for grape fruit ripening.
