Welcome to SAURs !

Auxin, widely distributed in higher plants, plays important roles in plant physiological processes such as apical dominance, leaf formation, embryo development, phototropism, tissue and organ patterning, fruit development, and root initiation and development. Most early auxin-response genes are classified into three large families: AUX/indole-3-acetic acids (IAAs), GRETCHEN HAGEN3s (GH3s), and small auxin-up RNA (SAUR). The SAUR domain mainly contains hydrophobic amino acids, short, highly conserved, charged patches and a nearly invariant cysteine residue. Surrounding the SAUR domain, SAUR proteins have lowly conserved N- and C-terminal extensions.
