Genome-wide analysis of PIN genes in cultivated peanuts (Arachis hypogaea L.): identification, subcellular localization, evolution, and expression patterns.

ABSTRACT:

Background

Auxin is an important hormone in plants and the PIN-FORMED (PIN) genes are essential to auxin distribution in growth and developmental processes of plants. Peanut is an influential cash crop, but research into PIN genes in peanuts remains limited.

Results

In this study, 16 PIN genes were identified in the genome of cultivated peanut, resolving into four subfamilies. All PIN genes were predicted to be located in the plasma membrane and a subcellular location experiment confirmed this prediction for eight of them. The gene structure, cis-elements in the promoter, and evolutionary relationships were elucidated, facilitating our understanding of peanut PINs and their evolution. In addition, the expression patterns of these PINs in various tissues were analyzed accordi
