Genome-Wide Characterization and Identification of Auxin Response Factor (<i>ARF</i>) Gene Family Reveals the Regulation of RrARF5 in AsA Metabolism in <i>Rosa roxburghii</i> Tratt. Fruits.

ABSTRACT: Rosa roxburghii Tratt., a fruit crop known for its high Vitamin C content and other nutritional compounds, has not yet been studied for its auxin response factor (ARF) family members. ARFs are important proteins in auxin-mediated pathways, playing a vital role in plant physiological and biochemical processes such as plant development, and flower and fruit maturation. In the present study, we identified 14 ARF genes (designated as RrARFs) in R. roxburghii, which are distributed across seven chromosomes and grouped into four subfamilies. An analysis of cis-acting elements revealed that these genes might be involved in various biological processes, including plant development, flower development, light responses, cell cycle regulation, phytohormone re
