VI1 — Zea mays
Summary
ZM00001EB083790 (VI1, also known as ZmCWIN4, ZmFRUCT5, and other synonyms) on maize chromosome 2 encodes a protein with beta-fructofuranosidase, fructan exohydrolase, inulase, and sucrose alpha-glucosidase activities, placing it in the Glyco_hydro_32 family. The gene is associated with phloem unloading and loading, carbohydrate storage, endosperm cellularization, hexose metabolism, and fructose uptake. It is linked to numerous agronomic traits including seed weight, width, length, and shape, kernel number per row, grain number and size, starch and amylose content, forage yield, stem thickness and diameter, seedling vigor, net photosynthetic rate, transpiration rate, heat tolerance, and cytoplasmic male sterility. The protein localizes to the vacuole, apoplast, cell wall, pollen tube, and stress granules. Studies of related genes in other species link the family to grain filling, seed development, yield, and stress tolerance.
