SG1 (TRAESCS2B02G195300) — triticum aestivum

Summary

TaSG1 (TRAESCS2B02G195300) on wheat chromosome 2B encodes a BAH domain-containing protein with chromatin, nucleic acid, RNA and protein binding activities. The gene is associated with epigenetic regulation of gene expression, transposable element silencing by heterochromatin formation, RNA-directed DNA methylation (RdDM), chromatin silencing, and cell cycle processes. It has been linked to leaf senescence, chlorophyll breakdown, ubiquitin-dependent proteolysis, and DNA and protein metabolism. The protein localises to the nucleus and macromolecular complexes. TaSG1 is associated with drought tolerance, net photosynthetic rate, hydrogen peroxide content, wheat stripe rust disease response, tillering, floral transition, abscisic acid sensitivity, and plant growth. Studies of related genes in other species connect the family to grain size, grain width, grain length, and grain weight traits.
