INTRODUCTION Green, black and pu-erh teas are known to have strong antiradical properties in comparison to other plant raw materials. In this study fifteen different teas belonging to three types, green, black, and pu-erh tea (five of each kind), were investigated for their antiradical properties. Antiradical activity of extracts and raw materials was measured using DPPH and ABTS(•+) radicals. ...

We have analyzed DNA methylation of plastid DNA from fully ripened red fruits, green mature fruits, and green leaves of tomato (Lycopersicon esculentum var. Firstmore). Essentially identical restriction profiles were obtained between chromoplast and chloroplast DNAs by EcoRI digestion. BstNI/EcoRII and HpaII/MspI are pairs of isoschizomers that can discriminate between methylated and unmethylat...

The effect of cadmium chloride on green gram (Vigna radiata Linn.) was studied using the parameters like carbohydrates, protein, chlorophyll and oxidative enzymes like superoxide dismutase, catalase and peroxidase of leaves inorder to know the possible involvement of cadmium metal in the generation of oxidative stress. Results obtained in this work showed that the application of cadmium decreas...

Nowadays, green chemistry and its advantages are generating interest of researchers toward ecofriendly biosynthesis of the metallic nanoparticles. In this research, a rapid, simple and green method was developed for the synthesis of silver nanoparticles using aqueous extract of Prangos ferulaceae leaves. The synthesized silver nanoparticles were characterized by UV-Vis spectroscopy, sc...

Papaya ringspot, caused by papaya ringspot virus, is the most important disease of the crop in Florida, severely limiting the potential for commercial production. Sometimes this virus infects cucurbits. Earliest symptoms in papaya appear as yellowing and vein-clearing of younger leaves. A prominent yellow mottling of the leaves follows. One or more lobes of infected leaves may become severely d...

The emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), is an exotic woodborer first detected in 2002 in Michigan and Ontario and is threatening the ash resource in North America. We examined the effects of light exposure and girdling on green ash (Fraxinus pennsylvanica Marsh) volatile production, and effects of light exposure, girdling, and leaf age on emerald ash bore...

Mosaic is a common disease symptom caused by virus infection in plants. Mosaic leaves of Tomato mosaic virus (ToMV)-infected tobacco plants consist of yellow-green and dark green tissues that contain large and small numbers of virions, respectively. Although the involvement of RNA silencing in mosaic development has been suggested, its role in the process that results in an uneven distribution ...

Introduction: Physalis alkekengi (Solanaceae) is a rich source of various antioxidants. There are some reports that show P. alkekengi has been used for treatment of a wide range of diseases including gout and inflammation. Xanthine oxidase plays a crucial role in gout. Many natural compounds such as various flavonoids have been reported to have inhibitory effect on xanthine oxidase. Metho...

Stay-green sorghum plants exhibit greener leaves and stems during the grain-filling period under water-limited conditions compared with their senescent counterparts, resulting in increased grain yield, grain mass, and lodging resistance. Stay-green has been mapped to a number of key chromosomal regions, including Stg1, Stg2, Stg3, and Stg4, but the functions of these individual quantitative tra...
