APO1 — Triticum turgidum subsp. durum

Summary

TRITD3AV1G247490 (APO1) on durum wheat chromosome 3A encodes an F-box domain-containing protein with ubiquitin-protein transferase activity, as a component of the SCF ubiquitin ligase complex. This gene is associated with regulation of auxin-mediated signaling, regulation of vasculature development, phloem or xylem histogenesis, leaf vascular tissue pattern formation, simple leaf morphogenesis, meristem cell maintenance, cell differentiation, regulation of cell population proliferation, regulation of flower development, flower development, regulation of DNA-templated transcription, protein ubiquitination, SCF-dependent proteasomal ubiquitin-dependent protein breakdown, and response to ozone. Additionally, APO1 is linked to spikelet number, grains per spike, grain number, and grain yield. The encoded protein localizes to the ubiquitin ligase complex and membrane. Studies of related genes in other species further connect the family to these developmental processes.
