RAD1 — Medicago truncatula

Summary

MTR_8G442410 (symbol RAD1) in barrel medic (Medicago truncatula) chromosome 8 encodes a GRAS family transcription factor with sequence-specific DNA binding and protein homodimerization activity. The gene is associated with arbuscular mycorrhizae formation, hyphopodium formation, cutin anabolism, and response to symbiotic fungi. It is linked to phosphate ion detection, cellular response to phosphate starvation, and response to nutrient levels. RAD1 is associated with regulation of seed dormancy, downregulation of seed germination, and downregulation of gibberellic acid mediated signaling, as well as GA-signaling and response to abscisic acid. The product localizes to both the nucleus and cytoplasm and is associated with root development and positive regulation of transcription by RNA polymerase II. Related genes in other species link the family to DELLA and GAI proteins.
