May act as a negative regulator of hypocotyl cell elongation in the light. Detected in the part of the veins in cotyledons of 6-day-old seedlings and the basal parts of the petioles in older plants. Highly expressed in the vascular tissues of hypocotyl in dark-grown seedlings. Overexpression of DTX52 alters shoot developmental programs leading to a loss of apical dominance phenotype. Belongs to the multi antimicrobial extrusion (MATE) (TC 2.A.66.1) family.
