RAM1 — Medicago truncatula

Summary

MTR_7G027190, symbol RAM1, encodes a GRAS family transcription factor with sequence-specific DNA binding and protein homodimerization activity. In barrel medic, RAM1 is associated with arbuscular mycorrhizae formation, hyphopodium formation, nodulation, and responses to symbiotic fungi. It has been linked to strigolactone and cutin anabolism, lipogenesis, pigmentation, morphogenesis, GA signaling, and cellular response to phosphate starvation. The gene product localizes to both the cytoplasm and nucleus. RAM1 is also associated with regulation of transcription by RNA polymerase II, DNA-dependent transcription, signaling, and response to nutrient levels. Related genes in other species connect the RAM1 family to arbuscular mycorrhizal symbiosis and phosphate starvation responses, though these associations are not yet established in barrel medic itself.
