Rhododendron dauricum is a cold-hardy shrub integrating ornamental, medicinal, and aromatic functions. Flower color an important feature related to ornamental value for breeders consumers. Nevertheless, the coloration mechanism of flower in R. still unclear. var. albiflorum white variety dauricum. In this study, integrative analysis metabolome transcriptome was conducted between A total nine an...

Flavonone 3 hydroxylases (EC 1.14.11.9) are key enzymes in the synthesis of anthocyanins and other flavonoids. Such compounds involved seed coat colour stem pigmentation. Lupinus mutabilis (tarwi) is a legume crop domesticated Andean region, valued for high protein oil content its seeds. Tarwi accessions being selected cultivation Europe under defined breeding criteria. Seed patterns relevant t...

The purple coloration of pepper leaves arises from the accumulation of anthocyanin. Three regulatory and 12 structural genes have been characterized for their involvement in the anthocyanin biosynthesis. Examination of the abundance of these genes in leaves showed that the majority of them differed between anthocyanin pigmented line Z1 and non-pigmented line A3. Silencing of the R2R3-MYB transc...

Abstract Background Leaf color is an important ornamental trait of colored-leaf plants. The change leaf closely related to the synthesis and accumulation anthocyanins in leaves. Acer pseudosieboldianum a tree native Northeastern China, however, there was less knowledge about biosynthesis many steps pathway remain unknown date. Results Anthocyanins metabolite transcript profiling were conducted ...

In vitro grown cabbage (Brassica oleracea var. capitata) seedlings exposed to excess molybdenum (Mo) ions exhibited severely reduced plant growth at the cotyledonary stage. Adding 80 mM proline (Pro) to the Mo-treated medium could help 50% seedlings to overcome the toxicity and grow true leaves. Under excess Mo stress, seedlings accumulated blue/purple anthocyanin in their cotyledons and hypoco...

Suppression subtractive hybridization (SSH) successfully identified 11 cDNAs in apple skin with highly induced expression as a result of ultraviolet (UV)-B irradiation. Apart from three putative flavonoid biosynthetic genes, chalcone synthase (CHS; A5C), flavanone-3-hydroxylase (F3H; B5F), and flavonol synthase (FLS; D1F), five clones (A1H, A10E, B11G, D5F, and D11H) were induced by low tempera...

Abstract The hook of Uncaria rhynchophylla is an important external phenotype representing the quality Gou-Teng. formation pattern U. displays a unique feature that solitary and opposite hooks alternately occur in leaf axils forming liner series. only grows on lower side axil, resulting from decline total yield hooks. However, reasons for are not clear. Therefore, survey molecular mechanisms ne...

Wolfberry (Lycium barbarum L.) is a small Solanaceae shrub with medicinal and edible homology, widely used as ethnobotanical medicine nutraceutical food. The wolfberry fruits mainly have red, purple, yellow phenotypes. Wolfberries are rich in flavonoids, which natural water-soluble pigments that endow variety of colors plants There very few investigations on mechanism flavonoids biosynthesis fr...

Flavonoids are important natural products for plant defence and human health. Although almost all the flavonoid pathway genes have been well-documented by biochemical and/or genetic approaches, the role of the Arabidopsis chalcone isomerase-like (CHIL) gene remains unclear. Two chil mutants with a seed colour similar to that of wild-type Arabidopsis have been identified here, but in sharp contr...
