SR33 — Brachypodium distachyon

Summary

BdSR33 (BRADI_1G20360V3) on chromosome 1 of Brachypodium distachyon encodes a protein with RNA-binding domains (RRM) and annotated cis-trans proline isomerase, protein kinase, and mRNA-binding activities. The gene is associated with spliceosomal complex assembly, regulation of alternative mRNA splicing, RNA splicing, sugar-mediated signalling, protein autophosphorylation, and response to abscisic acid. Its product localises to the nucleus, nucleolus, nuclear speck, cytosol, cytoplasm, mitochondria, and plasmalemma. BdSR33 is associated with traits including flowering time, root length and thickness, photosynthetic rate, anthocyanin content, seedling growth, leaf and flower morphology, chloroplast development, oxidative stress response, disease tolerance, and salt tolerance. Related genes in other species link the family to ABA sensitivity, seed germination, salt stress tolerance, innate immunity, DNA methylation, and oxidative stress tolerance.
