HAP2A — triticum aestivum

Summary

TaHAP2A (TRAESCS5D02G383000) on chromosome 5D encodes an NF-YA family protein with DNA-binding transcription factor activity, protein heterodimerization activity, and RNA polymerase II-specific transcription factor activity, and acts as a transcriptional co-regulator. It localizes to the nucleus, cytoplasm, plastid, and CCAAT-binding factor complex. The gene is associated with regulation of photomorphogenesis, long-day flowering, seed dormancy, microgametogenesis, meiotic cytokinesis, and the transition from vegetative to reproductive phase. It is linked to coumarin and phenylpropanoid metabolism, secondary cell wall biogenesis, lignin anabolism, and downregulation of gibberellic acid signaling and seed germination. Associations with agronomic traits include nitrate content and uptake, harvest index, ear number, starch content, anthocyanin content, leaf angle, stem elongation, salinity tolerance, and high temperature stress response.
