- OsMYBGA~OsGAMYB, OsMYBS1, Convergent starvation signals and hormone crosstalk in regulating nutrient mobilization upon germination in cereals, This study reveals two crucial transcription factors, MYBS1 and MYBGA, present in rice (Oryza sativa) and barley (Hordeum vulgare), that function to integrate diverse nutrient starvation and gibberellin (GA) signaling pathways during germination of cereal grains
- OsMYBGA~OsGAMYB, OsMYBS1, Convergent starvation signals and hormone crosstalk in regulating nutrient mobilization upon germination in cereals, GA antagonizes sugar repression by enhancing conuclear transport of the GA-inducible MYBGA with MYBS1 and the formation of a stable bipartite MYB-DNA complex to activate the alpha-amylase gene
- OsMYBGA~OsGAMYB, OsMYBS1, Convergent starvation signals and hormone crosstalk in regulating nutrient mobilization upon germination in cereals, We further discovered that not only sugar but also nitrogen and phosphate starvation signals converge and interconnect with GA to promote the conuclear import of MYBS1 and MYBGA, resulting in the expression of a large set of GA-inducible but functionally distinct hydrolases, transporters, and regulators associated with mobilization of the full complement of nutrients to support active seedling growth in cereals
