RAM1 — Medicago truncatula

Summary

MTR_4G064160 (RAM1, also known as MtGRAS2) encodes a GRAS family transcription factor with sequence-specific DNA binding and protein homodimerization activity. This nuclear-localized protein is associated with arbuscular mycorrhizae formation, hyphopodium formation, and strigolactone and cutin anabolism. RAM1 has been linked to the regulation of seed dormancy, downregulation of gibberellic acid signaling and seed germination, as well as responses to photooxidative stress, nutrients, and xenobiotic stimuli. The gene is connected to leaf growth and development, leaf senescence, root morphology, and disease tolerance traits. Studies of related genes in other species link the family to xenobiotic and oxidative stress tolerance, and to nematode resistance.
