ganoderma lucidum is one of the most well-known fungi, and has many applications in medicine. ganoderic acid is among the valuable secondary metabolites of ganoderma lucidum, and responsible for the inhibition of the tumor cell growth and cancer treatment. application of ganoderic acid has been limited because of low yields of its production from ganoderma lucidum. the present study aims to inv...

linum album l. is containing pharmaceutical composition podophyllotoxin(ptox) which is currently being used as a precursor to semi-synthetic anticancer drugs etoposide, teniposide and etopophos. cell culture is as an important source for the production of ptox. several strategies, including treatment with elicitors have shown for enhanced production of secondary metabolites in cell culture syst...

Kiwifruit (Actinidia deliciosa ) were cut into 5 mm slices and placed in polystyrene trays. Various volatile compounds were introduced inside the trays before the lids were covered. The development of decay and the shelf life of the slices were evaluated during storage at 10 8C. Kiwifruit slices treated with 2.24, 11.2, or 22.4 ml l 1 methyl jasmonate maintained good quality after 3 weeks at 10...

The shoots of Salvia officinalis growing in MS liquid medium supplemented with IAA 0.1 mg l-1) and BAP (0.45 mg l-1) were treated with methyl jasmonate (MeJA) to increase production of compounds with antioxidant activity (carnosic acid, carnosol and rosmarinic acid). The increase in metabolite production depended on MeJA concentration, the period of exposure to elicitor and type of compound. Th...

This study was conducted to investigate the effects of different silicon supplements and postharvest treatments on growth and yield of gerbera in a greenhouse experiment. Silicon supplements were including potassium silicate at three concentrations (0, 140 and 200 mg L−1), sodium silicate at three concentrations (0, 50 and 100 mg L−1) and rice hull ash (RHA) at three concentrations (0, 50 and 1...

background: trigonella foenum-graecum l. commonly known as fenugreek is a rich source of important medicinal metabolite, i.e. trigonelline. objective: in this study, hairy roots culture as a novel method for trigonelline production was evaluated. methods: for optimizing the hairy roots culture of trigonella foenum-graecum, three strains of agrobacterium rhyzogenes (atcc15834, msu440 and k599) v...

Methyl jasmonate has recently been found to have anti-cancer activity. Methyl jasmonate detached hexokinase 2 from a voltage dependent anion channel causing a reduction in mitochondrial transmembrane potential that led to the release of cytochrome C and apoptosis inducing factor resulting in intrinsic apoptosis. Blocked adenosine triphosphate synthesis caused by mitochondrial injury hampered ox...

Several abiotic stresses, including ethylene, methyl jasmonate, temperature, light, and wounding, were tested for their ability to induce accumulation of phenolic compounds and antioxidant capacity in purple-flesh potatoes (cv. All Blue). Results indicated that temperature, ethylene, methyl jasmonate, and light treatments did not significantly affect the accumulation of phenolic compounds compa...

In taproot of oilseed rape (Brassica napus L.), a 23 kDa polypeptide has been recently identified as a putative vegetative storage protein (VSP) because of its accumulation during flowering and its specific mobilization to sustain grain filling when N uptake is strongly reduced. The objectives were to characterize this protein more precisely and to study the effect of environmental factors (N a...

Portulaca oleracea L. is a medicinal plant find in Europe and Asia. This plant contains valuable secondary metabolite such as noradrenalin. Naturally the wild plant produce small amount of this secondary metabolites so induction of hairy roots can be useful to increase its production. In our research Agrobacterium rhizogenes strain AR15834 was used to induce hairy roots in the two-week leaf exp...
