Sugars such as glucose function as signal molecules that regulate gene expression, growth and development in plants, animals and yeast. To understand the molecular mechanisms of sugar responses, we isolated and characterized an Arabidopsis thaliana mutant, high sugar- response 8 (hsr8), which enhanc...
SUG1 associates with multiple transcription factors, such as OsBZR1, OsMADS56 and OsSPL13, to control grain size through GA and BR signaling as well as growth pathways.
