During grape berry (Vitis vinifera L.) ripening, sucrose transported from the leaves is accumulated in the berry vacuoles as glucose and fructose. To study the involvement of invertase in grape berry ripening, we have cloned two cDNAs (GIN1 and GIN2) from berries. The cDNAs encode translation products that are 62% identical to each other and both appear to be vacuolar forms of invertase. Both g...

Polyols are important metabolites that often function as carbon and energy sources and/or osmoprotective solutes in some plants. In grapevine, and in the grape berry in particular, the molecular aspects of polyol transport and metabolism and their physiological relevance are virtually unknown to date. Here, the biochemical function of a grapevine fruit mesocarp polyol transporter (VvPLT1) was c...

Glycation is associated with several neurodegenerative disorders, including Alzheimer's disease (AD), where it potentiates the aggregation and toxicity of proteins such as β-amyloid (Aβ). Published studies support the anti-glycation and neuroprotective effects of several polyphenol-rich fruits, including berries, which are rich in anthocyanins. Herein, blackberry, black raspberry, blueberry, cr...

The coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Scolytidae), is the most important pest of coffee throughout the world and is present in most coffee producing countries (Le Pelley, 1968). The insect is very difficult to control due to its cryptic life cycle which involves egg laying inside the coffee berry, followed by the emergence of adult females that are already inseminat...

Hydrodistillation of berries and leaves of Juniperus phoenicea grown in Sinai yielded volatile oils in the yield of 0.36 and 1.96%, respectively. Using gas chromatography/mass spectrometry technique, fifty eight compounds were identified in berry oil representing 99.2% of the oil composition. alpha-Pinene was the major compound in berry oil (39.30%) followed by sabinene (24.29%). Berry oil comp...

We obtain the adiabatic Berry phase by defining a generalised gauge potential whose line integral gives the phase holonomy for arbitrary evolutions of parameters. Keeping in mind that for classical integrable systems it is hardly clear how to obtain open-path Hannay angle, we establish a connection between the open-path Berry phase and Hannay angle by using the parametrised coherent state appro...

High purity berry plasma membranes (PMs) of Vitis vinifera L. cv. Cabernet Sauvignon were isolated by two-phase partitioning of microsome fractions at different stages of berry ripening. PM proteins resolvable by the detergent cocktail of CHAPS and ASB-14 were separated by two-dimensional electrophoresis. A total of 119 protein spots from pre-véraison berry PMs on 2-D gels detected with silver ...

This study investigated the effect of raw material, pressing, and glycosidase on the aromatic profile of goji berry wine. The free-run and the pressed juice of dried and fresh goji berries were used for wine production, whereas glycosidase was applied to wine after fermentation. Dried goji berry fermented wine exhibited much stronger fruity, floral, caramel, and herbaceous odors due to higher l...

Myrtle (Myrtus communis L.) leaf, stem and berry extracts were prepared to examine the total phenolics, flavonoids and condensed tannins contents. The antioxidant activities of crude extracts, ethyl acetate fraction, butanolic fraction, tannins and anthocyanins from these parts of plant were evaluated in vitro using reducing power and DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging...
