blt801 — Triticum aestivum

Summary

TRAESCS4B02G020300 (symbol blt801) on bread wheat chromosome 4B encodes an RRM domain-containing protein belonging to the SLIRP/GR-RBP-like family, with molecular functions including siRNA, miRNA, ssDNA, ssRNA, mRNA and general RNA binding. The gene is associated with mitochondrial gene expression, posttranscriptional regulation, RNA transport, and antiviral response, as well as carbohydrate breakdown and structural organization. It has been linked to cold acclimation, vernalization response, photoperiodism, and memory. Localization evidence connects the product to the nucleus, chloroplast thylakoid membrane, and ribonucleoprotein complexes. Trait associations include heading time, anthesis time, plant vegetative period, frost damage, cold tolerance, floret number, carotenoid content, plant height, and grain yield. Studies of related glycine-rich RNA-binding proteins in other species further link the family to stress responses and developmental regulation.
