MYB2 — Medicago truncatula

Summary

MTR_7G111290, also known as MtMYB50, MYB2, or MYB61, encodes a transcription factor with DNA-binding and chromatin-binding activity, belonging to the MYB and SANT/Myb domain families. In barrel medic, this gene is associated with pigmentation, seed coat development, xylem development, regulation of lignin anabolism, gibberellic acid homeostasis and signaling, regulation of seed dormancy, cold acclimation, the shikimate pathway, regulation of nitrogen utilization, salicylic acid mediated signaling, phloem transport, and green leaf volatile biosynthetic process. It is linked to numerous traits including seed set percent, shoot system elongation rate, whole plant size, plant male sterility, pollen fertility, anthocyanin content, chlorophyll content, flowering time trait, leaf senescence trait, root meristem development, and trichome morphology trait. Studies of related genes in other species associate the family with seed mucilage production, drought tolerance, stomatal regulation, root development, lignification, xylem formation, and gibberellin biosynthesis.
