Source	Description
UniProt	Involved in the positive regulation of tracheary element (TE) differentiation. Involved in a positive feedback loop that maintains or promotes NAC030/VND7 expression that regulates TE differentiation-related genes (PubMed:19088331). Functions in the initiation and emergence of lateral roots, in conjunction with LBD16, downstream of ARF7 and ARF19 (PubMed:19717544, PubMed:23749813). Transcriptional activator that directly regulates EXPA14, a gene encoding a cell wall-loosening factor that promotes lateral root emergence. Activates EXPA14 by directly binding to a specific region of its promoter (PubMed:22974309). Transcriptional activator that directly regulates EXPA17, a gene encoding a cell wall-loosening factor that promotes lateral root emergence (PubMed:23872272). Acts downstream of the auxin influx carriers AUX1 and LAX1 in the regulation of lateral root initiation and development (PubMed:26059335). {ECO:0000269\|PubMed:19088331, ECO:0000269\|PubMed:19717544, ECO:0000269\|PubMed:22974309, ECO:0000269\|PubMed:23749813, ECO:0000269\|PubMed:23872272, ECO:0000269\|PubMed:26059335}.
