May be involved in the regulation of ethylene receptor signaling. Promotes cell expansion and plant growth (Probable). Involved in the regulation of cell elongation (PubMed:24312429). Expressed in cotyledons, hypocotyls and roots of young seedlings. Expressed in emerging lateral root, leaves, flowers, stamens and filaments. Induced by ethylene in roots (PubMed:23134674, PubMed:24312429). Induced by auxin in roots. Down-regulated by abscisic acid (ABA) and paclobutrazol (PubMed:24312429). No visible phenotype under normal growth conditions. Plants over-expressing SAUR76 display increased root growth and reduced number of cells in leaves leading to reduced leaf area (PubMed:24312429). Plants silencing SAUR76 exhibit increased sensitivity to ethylene, while plants over-expressing SAUR76 display reduced ethylene sensitivity. Plants over-expressing SAUR76 exhibit increased rosette diameters (PubMed:26207341). Belongs to the ARG7 family. The article by Li et al was retracted by the editors after publication. Concerns were raised regarding a number of figure panels, such as partial overlap between the panels and duplication of protein gel analysis.
