AUR3 — Oryza sativa Japonica

Summary

OsAUR3 (also known as OsGH3.11, OsGH3.12, VAS2, and FIN219) on rice chromosome 5 encodes a protein containing a KIB1-4_b-propeller domain. The gene is associated with regulation of hormone anabolism, auxin metabolism, jasmonic acid anabolism, and JA signaling. It is linked to appressorium formation, secretion, systemic acquired resistance, NO storage, response to insect, photomorphogenesis, embryogenesis, seed development, seed germination, leaf development, and blue light response. Agronomically, the gene is associated with tiller angle, tiller number, plant height, harvest index, grain yield, seed viability, seed dormancy, chlorophyll content, sugar content, heat tolerance, and salt tolerance.
