MIPS1 — Glycine max

Summary

GmMIPS1 (GLYMA_05G180600V4) on soybean chromosome 5 encodes a myo-inositol-1-phosphate synthase, an enzyme with inositol-3-phosphate synthase activity. This gene is associated with inositol, phytate, phospholipid, oligosaccharide, and amino acid biosynthesis, as well as sucrose metabolism, cell cycle modulation, anther dehiscence, stomatal closure, seed development, and the cellular response to phosphate starvation. It has been linked to net photosynthetic rate, sucrose content, nitrate uptake, germination rate, pollen fertility restoration, stomatal resistance, and seedling growth. Associations also include embryo development, myo-inositol homeostasis, programmed cell death, oxidative stress tolerance, root growth, auxin transport, and pathogen response. The encoded protein localizes to the cytosol, nucleus, mitochondria, Golgi complex, and plant-type vacuole. Studies of related genes in other species link the family to salt tolerance, organ size, and female germline development.
