“…1). Gollop et al (2001Gollop et al ( , 2002 reported that the induction of anthocyanin biosynthesis genes by sugars is rather unspecific, and Glc, Fru, and Suc treatments result in the induction of DFR and ANS (LDOX) in grape. The sugar-sensing mechanisms operating in grape are poorly studied, and it is reasonable to assume that they might be distinct from the sugar-sensing mechanisms active in Arabidopsis.…”

“…Genes coding for dihydroflavonol reductase (DFR) and anthocyanidin synthase (ANS), also known as leucoanthocyanidin dioxygenase (LDOX), were up-regulated and the accumulation of anthocyanins was strongly increased by Suc in grape (Vitis vinifera) cells (Gollop et al, 2001(Gollop et al, , 2002, and signal transducers, such as Ca 21 and protein kinases/phosphatases, were shown to be involved in this process (Vitrac et al, 2000).…”

Sucrose-Specific Induction of the Anthocyanin Biosynthetic Pathway in Arabidopsis

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.

There are different target recognition sites for different groups of MYB proteins (Jin and Martin, 1999) and in addition to the core MYB DNA-binding site, all promoters contained putative cis-acting regulatory elements for different MYB proteins (data not shown).…”

“…ANS contains a multicomponent active site containing metal, co-substrate, and two molecules of a substrate analog (dihydroquercetin), according to analysis of the crystal structure of the enzyme in Arabidopsis (Wilmouth et al, 2002). ANS expression has been shown to be regulated in specific tissues and cell types during plant development in response to a variety of stimuli, including stress (Gollop et al, 2001;Bogs et al, 2005;Castellarin et al, 2007;Deytieux et al, 2007).…”

ABSTRACT. Anthocyanidin synthase (ANS), a 2-oxoglutarate (2OG) and Fe(II)-dependent oxygenase, catalyzes the penultimate step in anthocyanin biosynthesis, from leucoanthocyanidins to anthocyanidins, the first colored compound in the anthocyanin pathway. In this study, a full-length, 1427-bp long cDNA named RnANS1, which is homologous to the anthocyanidin synthase gene, was cloned from blackcurrant using a homologous cloning strategy. RnANS1 is highly homologous to other plant ANS genes at both the nucleotide and amino acid sequence levels. The deduced protein contains domains conserved in the 2OG and Fe(II)-dependent oxygenase, and is phylogenetically closely related to Paeonia suffruticosa and Paeonia lactiflora. The expression of RnANS1 was upregulated during fruit maturation, and correlated with the accumulation of anthocyanins and soluble carbohydrates in the fruit. Further characterization of the structure and expression patterns of RnANS1 will clarify our understanding of anthocyanin biosynthesis in (2015) blackcurrant, and support the development of molecular approaches to manipulate anthocyanin production in this plant.
