RAM2 — Medicago truncatula

Summary

MTR_5G091660 (RAM2, MtGPAT1) on barrel medic chromosome 5 encodes a glycerol-3-phosphate 2-O-acyltransferase with phosphatase activity, belonging to the HAD_RAM2/GPAT1-8 family. This gene is associated with glycerolipid metabolism, cutin and strigolactone anabolism, lipogenesis, fatty acid anabolism, and arbuscular mycorrhizae formation. It is linked to signaling, defense response, lipid transport, pollen sperm cell differentiation, and response to symbiotic fungi. The product localizes to membranes and mitochondria. Associations include plant height, seed oil biosynthesis, seed yield, microspore release, stamen filament elongation, plant growth, and embryonic development. Studies of related genes in other species link the family to male fertility, pollen development, tapetum differentiation, and fatty acid composition.
