FL1 — Zea mays

Summary

ZM00001EB028720 (FL1, also known as ZmFL1, FKD1, or ZmFKD1) on maize chromosome 1 encodes a protein with GTPase activator (GAP) activity and phosphoinositide-binding capacity, containing VAN3-binding-like and PH domains. This gene is associated with diverse biological processes including endosperm development, leaf vascular tissue pattern formation, 5S rRNA transcription, post-Golgi transport, DNA imprinting, phospholipid metabolism, ER stress response, and fermentation. FL1 localizes to the plasma membrane, nucleus, and trans-Golgi network transport vesicles. It is linked to starch digestibility, protein content, seed maturation, leaf vein morphology, and vascular tissue morphology. Phenotypic associations include endosperm vitreousness, leaf vein patterning, auxin transport and response, and endocytosis. Related genes in other species are linked to vascular patterning and continuity.
