In this study, 12 members of <i>VvPINs</i> were identified and distributed on 8 chromosomes. The <i>PIN</i> genes of five species were divided into two subgroups, and the similarity of exons/introns and motifs of <i>VvPIN</i> genes were found in the same subgroup. Meanwhile, according to the examination of conserved motifs, the motif 3 included the conserved structure NPNTY. The promoter region of VvPIN gene family contained various <i>cis</i>-acting elements, which were related to light, abiotic stress, and hormones which are essential for growth and development. Additionally, VvPIN1, VvPIN9, and VvPIN11 proteins simuPhysiology and molecular biology of plants : an international journal of functional plant biologyGenome-wide identification and expression analysis of <i>PIN</i> gene family under phytohormone and abiotic stresses in <i>Vitis Vinifera</i> L.PMC9723067No. Ganfx-03J022018LYQN01Nai GLu SGou HChen BMa WMao JfalseGenome-wide identification and expression analysis of <i>PIN</i> gene family under phytohormone and abiotic stresses in <i>Vitis Vinifera</i> L.The auxin efflux transport proteins PIN-formed (PIN) has wide adaptability to hormone and abiotic stress, but the response mechanism of <i>PINs</i> in grape remains unclear.
