Auxins play an important role in plant growth and development; the auxins responsive gene; auxin/ indole-3-acetic acid (Aux/IAA), small auxin-up RNAs (SAUR) and Gretchen Hagen3 (GH3) control their mechanisms. The GH3 genes function in homeostasis by the catalytic activities in auxin conjugation and bounding free indole-3- acetic acid (IAA) to amino acids. |
