Pan-genome identification and expression analysis of the ARF gene family in potato.

ABSTRACT:

Background

The auxin response factor (ARF) is a key regulator involved in plant growth, development, and stress response. In this study, we systematically identified the ARF gene family using a pan-genomic approach based on 47 high-quality potato genomes.

Results

Among the 28 members of the potato ARF pan-gene family, no core or private genes were identified. Only one gene was classified as near-core, while the remaining genes were considered non-essential. Ka/Ks analysis indicated that a single gene was under positive selection, whereas the rest of the family members were subject to purifying selection. Structural variations across the 21 potato genomes did not significantly alter the expression of ARF pan-gene family members, and no notable expression differences were dete
