PUB12 — Triticum aestivum

Summary

TRAESCS3A02G390200, also known as TaPUB2 or TaPUB12, encodes a U-box domain-containing protein with Armadillo repeats (ARM_PUB) that functions as a ubiquitin ligase (EC 2.3.2.27). This bread wheat gene on chromosome 3A is associated with the regulation of long-day photoperiodism and flowering, responses to salt stress, nitrate, karrikin, and molecules of bacterial origin. It has been linked to cell surface receptor signaling, downregulation of programmed cell death and defense responses, arbuscular mycorrhizae formation, and transition metal and calcium transport. The encoded protein localizes to the cytosol, cytoplasm, nucleus, and plasmalemma. TaPUB2 is associated with grain protein content, leaf chlorophyll content, salinity and heat tolerance, drought tolerance, seed germination, root length, stomatal resistance, and abscisic acid sensitivity. Related genes in other species connect the family to abiotic stress responses.
