Function
Transcription factor involved in crown root development (PubMed:26307379, PubMed:29740464). Promotes the development of crown roots (both initiation and elongation), main components of the fibrous root system (PubMed:26307379, PubMed:29740464). Regulates the expression of genes required for crown root development, and hormone-responsive genes involved in cytokinin signaling (e.g. RR1, RR2, RR3 and RR4), and auxin signaling (e.g. IAA5, IAA11, IAA23 and IAA31) (PubMed:26307379). Functions dowstream of the auxin biosynthetic genes YUCCA1 in the promotion of crown root development (PubMed:29740464).
