AP1 — Brachypodium distachyon

Summary

BRADI_2G36862V3 (BdAP1) on chromosome 2 of Brachypodium distachyon encodes an aspartic endopeptidase belonging to the phytepsin family, with saposin-like domains. The gene is associated with flower formation, inflorescence development, organogenesis, and specification of floral organ identity, as well as proteolysis and lipid metabolism. It is linked to protein storage vacuole and vacuole localization. BdAP1 has been connected to spikelet meristem identity, floral organ identity, meristem identity, organ identity, and anthesis time. Studies of related genes in other species link the family to heading time, seasonality, seed maturation, seed germination, grain yield, seedling vigor, root dry weight, leaf number, head wax, and SDS sedimentation.
