Abstract:

The mitochondrial phosphate transporter (MPT) gene family is an important functional protein located on the innner membrane of the nitochondria, transferring important metabolic substrate inorganic phosphate from the cytoplasm to the mitochondrial matrix through mitochondrial inner membrane and playing a key physiological role in maintaining the normal function of cells. Using bioinformatics tools, the phylogenetic evolution, structure, protein physicochemical properties and conserved motifs of grape MPT gene family members were systematically analyzed, as well as the tissue-specific expression and association of homologous gene. The results showed that sixty-four possible MPT family genes were identified in the whole genome of grapes, which could be divided into 7 groups according to the phylogenetic tree, distributed on 19 chromosomes, and two pairs of genes had a tandem replication phenomenon. Conservative motif analysis showed that all MPT family members contained the conserved domain of Mito_carr. Tissue-specific expression showed that VvMPT gene was highly expressed in peels, flowers and leaves. Homologous gene analysis showed that the VvMPT gene family of grapes might play an important role in the development of floral organs and maintenance of ion concentration.
