INO1 — Zea mays

Summary

ZM00001EB008360 (INO1, also known as ZmINO1, MIPS1, MIPS2 or MIPS3) on maize chromosome 1 encodes myo-inositol-1-phosphate synthase (EC 5.5.1.4). The gene is associated with inositol and phytate biosynthesis, phosphate and sulfate homeostasis, and phospholipid, polyamine and proline metabolism. It has been linked to seed viability, grain size, grain yield, starch and protein content, seedling vigour, plant height, leaf angle, tassel branch number, and responses to water, drought, cold and salinity. Localisation evidence places the product in the cytosol, nucleus, mitochondria, Golgi and vacuole. Related genes in other species have been linked to histone H3K27 monomethylation, transposon silencing and genome stability, as well as phytic acid content and salt tolerance.
