The red coloration of litchi fruit depends on the accumulation of anthocyanins. The anthocyanins level in litchi fruit varies widely among cultivars, developmental stages and environmental stimuli. Previous studies on various plant species demonstrate that anthocyanin biosynthesis is controlled at the transcriptional level. Here, we describe a litchi R2R3-MYB transcription factor gene, LcMYB1, ...

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...

Mulberry fruits contain large amounts of anthocyanins, polyphenols, flavonoids components and minerals which are important for human health. In this study, phytochemical properties some mulberry genotypes in theecologicalconditions the Malatya region were investigated. ‘Kenmochi’, ‘Bursa Siyah’, ‘44 BA 05’, ‘Elazığ İçme’, ‘23 MRK 09’ one patented ‘Ichinose’ cultivar studied concerning their tot...

Mahaleb (Prunus mahaleb L.) is an important rootstock for P. avium and P. cerasus cultivars. The present study has compared the phenolic contents and antioxidant activity of the methanolic extracts of the barks, leaves and fruits of ten selected mahaleb genotypes. The total phenolic content (5.11-131.77 mg GA g-1) in barks and the total flavonoid (54.06-180.6 mg QE g-1) and proanthocyanidin (8....

A MYB transcription factor gene, RsMYB1, from radish was introduced into the chrysanthemum cultivars 'Peach ND', 'Peach Red', and 'Vivid Scarlet' under the control of the cauliflower mosaic virus 35S promoter. Presence of RsMYB1 in transgenic lines was confirmed using polymerase chain reaction (PCR). Results of reverse-transcription-PCR analysis revealed that the expression of RsMYB1 was stable...

Purple foliage always appears in Camellia sinensis families; however, the transcriptional regulation of anthocyanin biosynthesis is unknown. The tea bud sport cultivar 'Zijuan' confers an abnormal pattern of anthocyanin accumulation, resulting in a mutant phenotype that has a striking purple color in young foliage and in the stem. In this study, we aimed to unravel the underlying molecular mech...

The influence of maturing and ripening on phenylalanine ammonia-lyase (PAL) activity and anthocyanin accumulation was examined using bagged, non-bagged and shaded ‘Jonathan’ (Malus domestica) apples. Bagged fruit were covered with paper bags from mid-June at an early stage of fruit growth. Shaded apples were insulated from sunlight by newspaper at the beginning of colouring (middle September). ...

Sage (Salvia officinalis L.) is cultivated worldwide especially in Mediterranean regions in which the leaves of this herb are widely used in pharmaceutical and food industries. Brassinolides and paclobutrazol are naturally occurring substances which modulate plant growth and development events and have been known to improve the crops tolerance to biotic and abiotic stresses. The effects of spra...

Natural dyes have become a viable alternative to expensive organic sensitizers because of their low cost of production, abundance in supply, and eco-friendliness. We evaluated 35 native plants containing anthocyanin pigments as potential sensitizers for DSSCs. Melastoma malabathricum (fruit pulp), Hibiscus rosa-sinensis (flower), and Codiaeum variegatum (leaves) showed the highest absorption pe...
