Identification of the Auxin Response Factor gene family in kernel consumption apricot and association analysis of related genes regulating fruit size in distant hybridization.

ABSTRACT:

Background

Distant hybridization is pivotal for fruit tree germplasm enhancement. Although successful hybridization has been achieved between kernel consumption apricot and almond, the hybrid progeny exhibits a consistent fruit size diminution compared to the maternal parent. Auxin Response Factor (ARF) is a key regulator of fruit size. However, the role of ARF family in regulating fruit size in kernel consumption apricot × almond distant hybridization remains uncharaterized.

Results

A total of 14 PaARF genes were identified in the kernel consumption apricot genome ('Longwangmao') and phylogenetically classified into five groups. All encoded conserved B3 and Auxin_resp domains, with seven containing an AUX_IAA domain. All PaARF genes exhibit a dispersed distribution pattern
