SAV3 — Arabidopsis thaliana

Summary

AT1G70560, also known as SAV3, TAA1, TIR2, and WEI8, encodes a pyridoxal phosphate-dependent aminotransferase with L-tryptophan:pyruvate transaminase activity (EC 2.6.1.99). The gene is associated with auxin signaling, auxin biosynthesis, and IAA biosynthetic processes. It has been linked to root growth, lateral root elongation, primary root development, and root meristem development. Associations also include responses to water and nitrogen levels, temperature stress, and aluminum. The gene is connected to leaf expansion, leaf shape, leaf thickness, and chlorophyll content. Additional associations involve gynoecium development, floral organ development, seed development, and plant male sterility. The encoded protein localizes to the cytoplasm, nucleus, and ER membrane. Studies of related genes in other species link the family to root branching, fruit shape, and plant height.
