RAM1 — Medicago truncatula

Summary

MTR_1G086970 (RAM1) on barrel medic chromosome 1 encodes a GRAS family transcription factor with sequence-specific DNA binding, protein homodimerization activity, and DNA binding transcription factor activity. It is associated with arbuscular mycorrhizae formation, hyphopodium formation, and response to symbiotic fungi. The gene is linked to strigolactone and cutin anabolism, lipogenesis, pigmentation, and morphogenesis. It has been connected to regulation of seed dormancy, downregulation of seed germination, and downregulation of gibberellic acid-mediated signaling. RAM1 is associated with cellular response to phosphate starvation, phosphate ion detection, and response to nutrient levels. The protein localizes to both the cytoplasm and nucleus. Related genes in other species, such as DELLA proteins and RGA1, link the family to gibberellin signaling and growth regulation.
