IP5 — Glycine max

Summary

GmIP5 (GLYMA_06G030100V4) encodes an inositol pentakisphosphate 2-kinase and is also annotated with RNA helicase activity. In soybean, this gene is associated with inositol phosphate anabolism, intracellular Pi homeostasis, and phytate biosynthesis. It has been linked to seed development, lateral root development, and responses to abiotic stresses including heat, cold, and osmotic stress. Associations with sucrose content, flowering time, root architecture, and root hair elongation have also been observed. The gene product localizes to the nucleus, nuclear envelope, and cytosol. Studies of related genes in other species link the family to seed phosphate and phytic acid content, arsenate tolerance, and defense responses, while work in tomato connects it to salicylic acid-dependent immunity and basal resistance to Pseudomonas syringae.
