Transcription factor involved in crown root development (PubMed:19258439, PubMed:26307379, PubMed:29740464). Promotes the development of crown roots (both initiation and elongation), main components of the fibrous root system (PubMed:19258439, 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). Recruits the ADA2-GCN5 histone acetyltransferase (HAT) module to regulate crown root cell proliferation and stem cell maintenance of root meristem (PubMed:28487409). Together with the ADA2-GCN5 HAT module targets and regulates a set of root-specific genes involved in carbon metabolism, cell wall biosynthesis, and auxin transport and response (PubMed:28487409). Functions upstream of several genes controlling root development, cytokinin homeostasis/signaling, stress response, and redox metabolic processes (PubMed:28830102). Interacts with ERF3 (PubMed:26307379). Interacts (via N-terminus) with ADA2 (PubMed:28487409). Expressed in crown roots (PubMed:19258439, PubMed:26307379). Expressed in the shoot apical meristem (SAM), leaf primordia, and young leaves (PubMed:26307379). In crown roots, mainly expressed after crown roots emergence but barely in crown root initials. Induced by auxin. Reduced crown root development (PubMed:19258439, PubMed:26307379). Severe growth defects and lethality in adult plants (PubMed:19258439). Overexpression of WOX11 stimulates ectopic crown root development. Belongs to the WUS homeobox family.
