SR33 (TRAESCS2A02G155100) — triticum aestivum

Summary

TRAESCS2A02G155100 (TaSR33) on chromosome 2A encodes a protein with RNA-binding domains (RRM, RBD) and exhibits cis-trans proline isomerase, protein kinase, and RNA-binding activities. The gene is associated with spliceosomal complex assembly, regulation of alternative mRNA splicing, and mRNA processing. It is linked to responses to heat, high light intensity, hydrogen peroxide, salinity, and ER stress, as well as heat acclimation and sugar-mediated signaling. TaSR33 localizes to the nucleus, nucleolus, nuclear speck, cytoplasm, cytosol, mitochondria, and plasmalemma. Associations with agronomic traits include stem rust resistance, salt tolerance, photosynthetic rate, flowering time, root development, anthocyanin content, and seedling growth. Studies of related genes in other species link the family to root development, flowering time, flower morphology, seed number, and silique length.
