BAG1 — triticum aestivum

Summary

TRAESCS7B02G167800 (TaBAG1) on wheat chromosome 7B encodes a BAG chaperone regulator domain protein with adenyl-nucleotide exchange factor activity and protein binding capacity. It is associated with protein stabilization, cytoplasmic protein quality control via the ubiquitin-proteasome system, and localization. The gene has been linked to leaf senescence, chlorophyll breakdown, chlorophyll fluorescence, secondary cell wall biogenesis, lignin and coumarin anabolism, phenylpropanoid and carbohydrate metabolism, and responses to heat and wounding. Associations include anther extrusion, pollen fertility, heterosis, heat tolerance, high temperature stress response, nitrate transport, and chlorophyll content. The product localizes to the cytoplasm, nucleus, cytosol, and mitochondria. Related genes in other species link the family to heat stress tolerance, disease and cell wall phenotypes, salt tolerance, seed setting rate, pollen viability, and pollen development.
