Sugars act as signaling molecules, whose signal transduction pathways may lead to the activation or inactivation of gene expression. Whole-genome transcript profiling reveals that the flavonoid and anthocyanin biosynthetic pathways are strongly up-regulated following sucrose (Suc) treatment. Besides mRNA accumulation, Suc affects both flavonoid and anthocyanin contents. We investigated the effects of sugars (Suc, glucose, and fructose) on genes coding for flavonoid and anthocyanin biosynthetic enzymes in Arabidopsis (Arabidopsis thaliana). The results indicate that the sugar-dependent up-regulation of the anthocyanin synthesis pathway is Suc specific. An altered induction of several anthocyanin biosynthetic genes, consistent with in vivo sugar modulation of mRNA accumulation, is observed in the phosphoglucomutase Arabidopsis mutant accumulating high levels of soluble sugars.

Water deficits accelerate ripening and induce changes in gene expression regulating flavonoid biosynthesis in grape berries (2007, background): “On the other hand, anthocyanin production was induced where it was otherwise not present in a sugar accumulating mutant of Arabidopsis ( Solfanelli et al. 2006 ) and cultured grape berry cells when they were exposed to exogenous sugars (Gollop et al. 2002).”
Sugars induce anthocyanin accumulation and flavanone 3-hydroxylase expression in grape berries (2009, methodology): “induced by sugars in Arabidopsis ( Solfanelli et al. 2006 ), soybean leaves (Sadka et al. 1994) and grape cells suspension (Vitrac et al. 2000).”

Sucrose signaling pathways leading to fructan and anthocyanin accumulation: A dual function in abiotic and biotic stress responses? (2014, background): “Such Suc-specific signaling pathways are 25 involved in the synthesis of two types of vacuolar compounds: anthocyanins (Teng et al., 26 2005; Solfanelli et al., 2006) and fructans (Martínez-Noël et al., 2009, 2010).”
Anthocyanin Function in Vegetative Organs (2008, background): “The anthocyanin biosynthetic pathway is strongly upregulated by sucrose in plants as diverse as radish (Raphanus sativus), English ivy (Hedera helix), and Arabidopsis thaliana (Murray and Hackett 1991; Hara et al. 2003; Solfanelli et al. 2006 ).”
The Flavonoid Biosynthesis Network in Plants (2021, background): “Like FLS, F3H, and FNSI, ANS/LDOX is also a FeII/2-oxoglutaratedependent dioxygenase, and catalyzes the dehydroxylation of C-4 and the formation of a double bond in ring C [3,124].”
Multiple functional roles of anthocyanins in plant-environment interactions. (2015, background): “antagonists do not act synergistically with sugar in increasing the anthocyanin accumulation (Solfanelli et al., 2006).”
