RAM2 — Medicago truncatula

Summary

MTR_3G048330 (RAM2, MtGPAT1) on barrel medic chromosome 3 encodes a protein with glycerol-3-phosphate 2-O-acyltransferase activity and phosphatase activity, placing it in the phospholipid/glycerol acyltransferase family. The gene is associated with glycerolipid metabolism, strigolactone and cutin anabolism, lipogenesis, fatty acid anabolism, and lipid transport. It is also associated with signaling, defense response, arbuscular mycorrhizae formation, response to symbiotic fungi, and pollen sperm cell differentiation. The product localizes to the membrane and mitochondria. Associations with plant height, seed oil biosynthesis, seed yield, microspore release, stamen filament elongation, plant growth, and embryonic development have been noted. Related genes in other species are linked to male fertility, tapetum differentiation, pollen development, and fatty acid composition.
