Structural Organization and Functional Activity of the Orthologous TaGLW7 Genes in Bread Wheat (Triticum aestivum L.)

It is reported that GLW7 encoding the transcription factor OsSPL13, positively regulates grain size and shape in rice. We have limited knowledge about its orthologs in wheat. Here, based on the rice OsGLW7 we isolated and identified the TaGLW7 gene in wheat, characterized its nucleotide and protein structures, predicted the cis-elements of its promoter, analyzed its expression patterns. The orthologs in barley (HvGLW7), Brachypodium (BdGLW7),...
