Furonaphthoquinones are promising skeletons for anticancer drug molecules. In particular, methoxylated furonaphthoquinones are characteristic constituents of Tabebuia plants. In this research, we synthesized the furonaphthoquinones by effective one-pot cascade reactions of 3-phenyliodonio-1,2,4-trioxo-1,2,3,4-tetrahydronaphthalenides with 3-butyn-2-ol in the presence of palladium and cuprous ca...

Conducting poly(o-toluidine) (POT) and poly(m-toluidine) (PMT) blends containing 10, 30, 50, 70, and 90 % wt/wt of polystyrene (PSt) were prepared by employing a two-step emulsion pathway. The bands characteristic of both polystyrene and POT/PMT are present in the IR spectra of POT–PSt and PMT–PSt blends. The UV-visible spectra of POT–PSt and PMT–PSt blends exhibit two bands around 313 and 610 ...

As part of the EU project MULTIBARRIERS, six new endogenous aerobic bacterial isolates able to grow in the presence of BTmX (benzene, toluene, m-xylene) were characterized with respect to their growth specificities. Preliminary analysis included restriction fragment length polymorphism profiles and 16S rDNA sequencing. The diversity of these strains was confirmed by denaturing gradient gel elec...

Antifungal activity of ethanol-water extracts of four medicinal plants, cinnamon (Cinnamomum verum Presl.), anise (Pimpinella anisum L.), black seed (Nigella sativa L.) and clove (Syzygium aromaticum L. Merr. & Perry.) was investigated against pea (Pisum sativum L.) root-rot fungus Rhizoctonia solani. In vitro antifungal activity test shown a high growth inhibition at concentration (4%) of each...

A pot experiment examined the biomass and As uptake of Medicago truncatula colonized by the arbuscular mycorrhizal (AM) fungus Glomus mosseae in low-P soil experimentally contaminated with different levels of arsenate. The biomass of G. mosseae external mycelium was unaffected by the highest addition level of As studied (200 mg kg(-1)) but shoot and root biomass declined in both mycorrhizal and...

Cucurbita pepo L. plants were grown in plastic pots with 2 kg washed sand per pot at three levels of potassium and sodium nitrate supplies to investigate the effects of nitrate supply on nitrate reductase activity and nitrate reductase expression in the leaves of the plants. Results demonstrated that starvation leads to decrease nitrate reductase activity and nitrate reductase expression. Suppl...

The pot experiments were conducted in the Department of Life Science and Bioinformatics of Assam University, Silchar. The aim of the present study was to investigate the effect of dual inoculation of Arbuscular mycorrhiza (AM) (Glomus fasciculatum) and Rhizobium on the chlorophyll, nitrogen and phosphorus contents of pigeon pea (Cajanus cajan L.). The results revealed an overall increase in chl...

In India, several species of Meloidogyne are reported on a variety of vegetables, cereals, pulses and ornamental plants. Root knot disease caused by M.incognita is a matter of great concern because this species affects several economically important crop plants. Okra is a very important crop by nutrition and health wise. In the present study the application of various parts of neem (seeds, leav...

A pot experiment was carried out on hybrid drumstick PKM 1 added with inorganic and organic fertilisers. Seeds of hybrid Drumstick PKM1 were sown in the plastic pots in glass house condition. Single inorganic fertilizer, phosphate solubiliser and bio organic fertilizer as well as in different combinations were applied to the pots. Data revealed that plant height, fresh and dry biomass, moisture...

although micronutrients effect on growth and yield of different plants has been intensively investigated, but there is limited information on its effect on grain yield and seed oil content of pot marigold) calendula officinalis l.). in order to investigate the effects of micronutrients (fe, zn and mn) spraying on yield and yield components and seed oil of pot marigold, a field experiment was co...
