SR33 (TRAESCS2D02G160400) — triticum aestivum

Summary

TRAESCS2D02G160400 (TaSR33, also known as TaSCL33-2D) on wheat chromosome 2D encodes a protein with RNA-binding, protein kinase, and cis-trans proline isomerase activities, and contains RRM and RBM domains. The gene is associated with RNA splicing, spliceosomal complex assembly, and regulation of alternative mRNA splicing. It has been linked to responses to heat, high light intensity, hydrogen peroxide, and abiotic stress, as well as ER stress response, protein folding and unfolding, and sugar-mediated signaling. TaSR33 is associated with grain yield, stem rust resistance, salt tolerance, photosynthetic rate, chloroplast development, flowering time, and disease tolerance. The protein localizes to the nucleus, nucleolus, cytoplasm, mitochondria, and nuclear speck. Studies of related genes in other species link the family to ABA sensitivity, seed germination, and salt stress tolerance.
