BACKGROUND Diverse enzymatic and non-enzymatic antioxidants provide protection against reactive oxygen species in humans and other organisms. The nonenzymatic antioxidants include low molecular mass molecules such as plant-derived phenols. AIM OF STUDY This study identified the major phenolic compounds of a grape seed extract by HPLC and analyzed the effect of consumption of biscuits enriched...

Endophytes have been verified to synthesize melatonin in vitro and promote abiotic stress-induced production of endogenous melatonin in grape (Vitis vinifera L.) roots. This study aimed to further characterize the biotransformation of tryptophan to melatonin in the endophytic bacterium Pseudomonas fluorescens RG11 and to investigate its capacity for enhancing endogenous melatonin levels in the ...

The anthocyanin composition, fatty acids, and volatile aromas are important for Cabernet Sauvignon grape quality. This study evaluated the effect of exogenous abscisic acid (ABA) and methyl jasmonate (MeJA) on the anthocyanin composition, fatty acids, lipoxygenase activity, and the volatile compounds of Cabernet Sauvignon grape berries. Exogenous ABA and MeJA improved the content of total antho...

The effects of vermicomposts on plant parasitic, fungivorous and baterivorous nematode populations were investigated in grape (Vitis vinifera) and strawberry (Fragaria ananasa) field crops. Commercially-produced vermicomposts derived from recycled paper, and supermarket food waste were applied to replicated plots at the rates of 2.5 t ha–1 or 5.0 t ha–1 for the grape crop and 5.0 t ha–1 or10 t ...

Growth-regulating factors (GRFs) are plant-specific transcription factors that have important functions in regulating plant growth and development. Previous studies on GRF family members focused either on a single or a small set of genes. Here, a comparative genomic analysis of the GRF gene family was performed in poplar (a model tree species), Arabidopsis (a model plant for annual herbaceous d...

K+ is the most abundant cation in the grape berry. Here we focus on the most recent information in the long distance transport and partitioning of K+ within the grapevine and postulate on the potential role of K+ in berry sugar accumulation, berry water relations, cellular growth, disease resistance, abiotic stress tolerance and mitigating senescence. By integrating information from several dif...

α-Amylase inhibitor from Vigna unguiculata seeds (VUAI) was purified using ionexchange chromatography on Poros HS-50 column. Plant cell culture was used as it provides a controlled environmental and nutritional condition. VUAI used in different concentrations as 10, 100 and 200 ppm was found to increase the biomass of both grape and peanut callus cells in liquid media. Increased anthocyanin con...

The aim of this work was to study the co-composting process of the solid phase of the digestate (PSD) obtained from the anaerobic digestion of pig slurry, with agricultural and agro-food wastes, such as wheat straw (WS), vine shoot pruning (VP), pepper plant pruning (PP) and exhausted grape marc (EGM), as well as the final added-value properties of the composts obtained. All the composting mixt...
