IP5 — Glycine max

Summary

GmIP5 (GLYMA_14G072200V4) encodes an inositol pentakisphosphate 2-kinase, an enzyme with inositol-1,4,5,6-tetrakisphosphate 2-kinase activity that also binds ATP and metal ions. In soybean, this gene is associated with phytate biosynthesis, inositol phosphate anabolism, intracellular Pi homeostasis, and sulfur amino acid anabolism. It is linked to seed development, protein storage, sucrose metabolism, lateral root development, and responses to heat, cold, bacteria, and fungi. Associations with agronomic traits include days to maturity, seed weight, protein content, sucrose content, seed coat color, plant height, and flowering time. The gene is also connected to root architecture, root hair elongation, phosphate sensing, osmotic stress tolerance, and phytic acid content. Studies of related genes in other species link the family to seed phosphate and phytic acid content, arsenate tolerance, and plant growth.
