APO1 — Triticum turgidum subsp. durum

Summary

TRITD7AV1G215820 (symbol APO1, also known as TtFBOX013 and FBOX013) on durum wheat chromosome 7A encodes a protein with ubiquitin-protein transferase activity, a component of the SCF ubiquitin ligase complex. The gene is associated with meristem cell maintenance, phloem or xylem histogenesis, regulation of flower development, cell differentiation, and response to ozone. It has been linked to spikelet number, grains per spike, grain number, and grain yield. Related genes in other species are associated with grain shape, amylose content, spike length, grain weight, anthesis time, and plant height.
