Azadirachtin has high industrial demand due to its immediate application as an ecofriendly, biodegradable biopesticide and also due to its various other significant bioactivities. To date, the only commercially feasible way to produce azadirachtin is extraction from seeds, but their availability is very limited as the tree flowers only once a year and only one-third of the fruits are collected ...

We compared the subcellular distribution of native and artificial reticuloplasmins in endosperm, callus, and leaf tissues of transgenic rice (Oryza sativa) to determine the distribution of these proteins among endoplasmic reticulum (ER) and post-ER compartments. The native reticuloplasmin was calreticulin. The artificial reticuloplasmin was a recombinant single-chain antibody (scFv), expressed ...

Tissue culture is an attractive alternative for plant propagation. Micropropagation is a technique to ensure a constant and uniform source of ornamental plants. Matthiola incana is an important ornamental species mainly cultivate by seed. Matthiola incana seeds were germinated on solid MS medium without plant growth regulators. Shoot proliferation and root formation are possible using kinetin (...

Background: Colchicine acts as a polyploidy inducer but at high concentrations, it causes cell mortality. To improve the efficiency of colchicine polyploidization in cassava, leaf lobes colchicine-sensitivity tests were carried out and LD50 determined 0.00, 0.05, 0.10, 0.20 0.25g/l concentrations varieties Ankrah, Dagati, Tomfa Tuaka. Methods: treated regenerated into callus on either 8 mg/l 2,...

In the last years many studies on anthocyanins, the flavonoids responsible for the orange, red and blue colors in different plant organs, have revealed their antioxidant activity and a possible use as chemotherapeutics. The finding that tart cherries (Prunus cerasus L.) contain a great amount of anthocyanins, constituents that possess strong antioxidant and anti-inflammatory activities, have at...

Plant triterpenoids represent a large and structurally diverse class of natural products. A growing interest has been focused on triterpenoids over the past decade due to their beneficial effects on human health. We show here that these bioactive compounds are major constituents of several aerial parts (floral bud, leaf bud, stem, and leaf) of olive tree, a crop exploited so far almost exclusiv...

Availability of quality seeds in production krisan (Chrysanthemum morifolium Ramat cv Dewi ratih) cultivation is still rare, therefore research on seed multiplication through tissue culture needed. The media used relatively expensive for home industry. This study aims to determine the respond leaf and stem explants using foliar fertilizers (Growmore, Gandasil D Mutiara) as an alternative callus...

The antibacterial activity of Wrightia tinctoria (Roxb.) R. Br. callus extract was studied against selected pathogenic bacterial strains, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Bacillus subtilis by Agar disc diffusion method. Among the three solvents and water were used , methanol extract of callus showed higher inhibition zone against Pseudomonas aeruginosa (27 mm)...
