MYB306 — Medicago truncatula

Summary

MTR_3G039990 (MYB306) in barrel medic (Medicago truncatula) encodes a Myb-domain transcription factor with sequence-specific DNA binding and transcription cis-regulatory region binding activity. The gene is associated with pigment accumulation in tissues, including phlobaphene biosynthetic and proanthocyanidin anabolic processes, as well as flavonoid anabolism. MYB306 is associated with seed development, seed coat color, nodulation, stomatal movement, and responses to auxin, salinity, and drought tolerance. It is also linked to the upregulation of phytoalexin biosynthesis, defense response to insects, regulation of lignin anabolism, and green leaf volatile biosynthetic processes. The encoded protein localizes to the nucleus. Studies of related genes in other species connect the MYB306 family to pigment and defense pathways.
