Indole-3-acetic acid (IAA) is the most active endogenous auxin and is involved in various physiological processes in higher plants. Concentrations of IAA in plant tissues are regulated at multiple levels including de novo biosynthesis, conjugation/deconjugation, and degradation. In this paper, we report molecular isolation and biochemical characterization of a gene PtIAMT1 from poplar encoding IAA methyltransferase (IAMT), which plays a role in regulating IAA homeostasis. PtIAMT1 was identified… CONTINUE READING
