Genome-wide identification and expression analysis of PIN gene family under phytohormone and abiotic stresses in Vitis Vinifera L.

ABSTRACT: The auxin efflux transport proteins PIN-formed (PIN) has wide adaptability to hormone and abiotic stress, but the response mechanism of PINs in grape remains unclear. In this study, 12 members of VvPINs were identified and distributed on 8 chromosomes. The PIN genes of five species were divided into two subgroups, and the similarity of exons/introns and motifs of VvPIN 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 cis-acting elements, which were related to light, abiotic stress, and hormones which are essential for growth and development. Additionally, VvPIN1, VvPIN9, and VvPIN11 proteins simu
