AtIAR1 is a Zn transporter that regulates auxin metabolism in Arabidopsis thaliana.

Journal of experimental botany - 28 Feb 2024

Gate Thomas, Hill Lionel, Miller Anthony J, Sanders Dale

Abstract excerpt

Root growth in Arabidopsis is inhibited by exogenous auxin-amino acid conjugates, and mutants resistant to one such conjugate [indole-3-acetic acid (IAA)-Ala] map to a gene (AtIAR1) that is a member of a metal transporter family. Here, we test the hypothesis that AtIAR1 controls the hydrolysis of stored conjugated auxin to free auxin through zinc transport. AtIAR1 complements a yeast mutant sensitive to zinc, but...
