RAM1 — Medicago truncatula

Summary

MTR_2G097380 (symbol RAM1, also known as MtGRAS2) encodes a GRAS family transcription factor with sequence-specific DNA binding and protein homodimerization activity. In barrel medic, this gene is associated with hyphopodium formation, strigolactone and cutin anabolism, pigmentation, isoflavonoid biosynthesis, and regulation of seed dormancy and germination. It is linked to responses to photooxidative stress, xenobiotic stimuli, nutrients, and phosphate detection, as well as salicylic acid-mediated systemic acquired resistance and downregulation of gibberellic acid signaling. The protein localizes to the nucleus, cytosol, and cytoplasm. Associations with plant height, leaf size, leaf senescence, petiole length, root morphology, and disease tolerance have been recorded. Related genes in other species are linked to oxidative stress tolerance, detoxification responses, and defense against necrotrophic pathogens.
