A schematic representation of glucose (Glc) signaling wherein AtRH57 acts as a crucial player in the feedback inhibition of ABA accumulation within the sugar-mediated ABA signaling pathway during Arabidopsis seed germination and early seedling growth. HXK1, hexokinase1; ABA, abscisic acid; ABA biosynthesis genes: ABA2,ABA3, and AAO3; ABA signaling genes: ABI3,ABI4, and ABI5.
