VI1 — Zea mays
Summary
ZM00001EB242820 (VI1, also known as ZmCWIN4) on maize chromosome 5 encodes a beta-fructofuranosidase with 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, endosperm cellularization, carbohydrate storage, nectar secretion, and cellular response to gibberellin. Its product localizes to the vacuole, apoplast, plant-type cell wall, pollen tube, and stress granule. VI1 is associated with kernel number per ear, grain moisture content, stay green, starch digestibility, amylose and sucrose content, seed weight, harvest index, heterosis, heat tolerance, photosynthetic rate, grain number and size, and root volume. Studies of related genes in other species connect the family to grain filling, seed development, pollen development, male sterility, yield, and carbon partitioning.
