Genome-Wide Identification of <i>GmARF9b</i>/<i>GmARF2a</i> Negatively Regulate Root Growth in Soybean.

ABSTRACT: Auxin is the most important phytohormone, regulating root growth and development in plants. ARFs function as central regulators in auxin signaling in model plants, and the functions of ARF activators have been widely investigated, while the functions of ARF repressors remain elusive. In this study, we investigated the family of GmARFs in soybean through a genome-wide expression pattern and functional study of roots highly expressing ARFs. In total, we identified 59 GmARF members in the soybean genome. GmARFs harbor canonical B3 DNA-binding (B3), ARF (Aux rep), and PB1 functional protein domains. We identified two potential repressor genes, GmARF9b (Glyma.03G070500) and GmARF2a (Glyma.05G200800), which are specifically or highly expressed in
