RD22 (TRAESCS3A02G280600) — triticum aestivum

Summary

TRAESCS3A02G280600, designated TaRD22 (also known as TaBURP17-3A), encodes a BURP domain-containing protein with nutrient reservoir activity and mRNA binding capacity. This wheat gene on chromosome 3A is associated with pollen maturation, response to desiccation, and numerous metabolic processes including vitamin, sulfur compound, and aromatic amino acid metabolism, as well as photosynthesis and photosystem II light harvesting. It localizes to the exine, orbicule, protein storage vacuole, and endomembrane system. TaRD22 is associated with grain number per plant, grain weight per spike, grain yield, plant height, spike length, and days to heading. It is associated with salt tolerance and dehydration response. Related genes in other species link the family to drought tolerance, abscisic acid response, and traits such as carotene content, lignin content, and pollen fertility.
