anthocyanins; antioxidant activity; biochemical pathways; biosynthesis; cinnamic acid; color; cyanidin; delphinidin; ferulic acid; gene expression; gene expression regulation; genes; genotype; grapes; malvidin; proanthocyanidins; small fruits; transcriptomics; wines
Abstract:
... Gene expression profile, phenolic composition, and antioxidant capacity were evaluated in red-fleshed berries and their wines (RF berries and wines) from new grape genotypes. Transcriptomic analysis revealed that ten metabolic pathways involved in polyphenol synthesis and catabolism were significantly altered, and 13 genes related to the biosynthesis and transport of phenolics were largely upregul ...

Abstract:
... Camellia sinensis var. pubilimba, one variety of the genus Camellia sect. Thea (Theaceae), has been used for producing green tea mainly by the local people of its growing areas of Guangxi province, China. Forty compounds, including eight C-8 N-ethyl-2-pyrrolidinone-substituted flavan-3-ols (1–8) and their substituted unit N-ethyl-5-hydroxy-2-pyrrolidinone (9), four flavan-3-ol monomers (10–13) and ...

Subject:
Brassica oleracea var. italica; adenosine triphosphate; antioxidant activity; antioxidants; broccoli; energy; germination; nutrition; phenolic compounds; pigments; proteins; seeds; sprouting; sugars
Abstract:
... The role of energy status in germination and sprouting of broccoli seeds was investigated by exogenous ATP and DNP treatments. With the synthesis of adenylates from 38.82 to 142.69 mg·100 g–¹ DW, the nutritive components (soluble sugar, proteins, pigments, and phenolics) and AAs were increased during germination and early sprouting (day 5). Elements of the BoSnRK2 pathway were down-regulated by mo ...
