This paper reports the occurrence of both free and glycosidically bound aroma compounds in three sweet cherry cultivars ('Hongdeng', 'Hongyan' and 'Rainier'), with 97 compounds being identified in the three cultivars. The major free volatile compounds found were hexanal, (E)-2-hexenal, (E)-2-hexen-1-ol, benzyl alcohol and benzaldehyde. The major bound(More)
L-Idonate dehydrogenase (L-IdnDH) is the only known enzyme of the tartaric acid (TA) biosynthetic pathway in grape berries. Previous studies on this enzyme only focused on the transcriptional expression of this gene. Here, the antibody against L-IdnDH was prepared by cloning the full-length cDNAs of VvIdnDH from grape berries, highly expressing fusion(More)
Terpenes are of great interest to winemakers because of their extremely low perception thresholds and pleasant floral odors. Even for the same variety, terpene profile can be substantially different for grapevine growing environments. Recently a series of genes required for terpene biosynthesis were biochemically characterized in grape berries. However, the(More)
3-Deoxy-d-arabino-heptulosonate 7-phosphate synthase (DAHPS) is an entry enzyme of the shikimate pathway that connects primary carbohydrate metabolism with the biosynthesis of most secondary metabolites in plants. In the present study, two DAHPS cDNAs were cloned from grape berries (Vitis vinifera) and designated as VvDAHPS-1 and VvDAHPS-2. These two cDNA(More)
Modulation of flavonoid biosynthesis in grape berries has always aroused great attention among researchers. However, little study has been made on the shikimate pathway that guides photo-assimilate flow into flavonoid metabolism. The present study indicated that the treatments of three ultraviolet (UV) wavelengths differentially up-regulated transcriptional(More)
Organic acids play a primary role in defining grape flavor and wine organoleptic properties. China-originated grape species contain high level acid, which limits to a certain extent, the marketing of fruits and their processing products. The objective of this study is to compare the changes of four organic acids along with grape berry development in(More)
The phenolic and proline content were determined in honey samples of different floral origins (rapeseed, sunflower, buckwheat and Codonopsis) from five different regions of China. The phenolic and proline profile of these samples were used to construct a statistical model to distinguish honeys from different floral origins. Significant differences were(More)
HIGHLIGHTS A similar trend on accumulation of glycosidically bound monoterpenes was observed in both varietiesTwo VvGT7 alleles mutations occurred at key sites in Muscat blanc à PetitVvGT14 exerted a major role in production of monoterpenyl glycosides in both varieties Terpenoids are the major aroma components and generally exist as both free and(More)
Myostatin(MSTN) gene is expressed specifically in developing and mature skeletal muscle, and the expression products of MSTN gene inhibits muscle growth and differentiation. The polymorphism of the porcine MSTN gene was researched by PCR-SSCP. The SSCP was found in the MSTN gene exon 2 and exon 3. It showed three genotypes (CC, CT, TT) in exon 2 and two(More)
