Many factors may influence the efficiency of somatic embryogenesis. This capability may be differ with regard to media compositions, genotype, tissue, organ ontology and the stage of differentiation. The effects of five salicylic acid concentrations (0, 25, 50, 75 and 100 mM) on different stages of carrot somatic embryogenesis were studied using petiole and root secondary phloem explants as sta...

A novel acyltransferase from cotyledons of tomato (Lycopersicon esculentum Mill.), which catalyzes the transfer of caffeic acid from chlorogenic acid (5-O-caffeoylquinic acid) to glucanc and galactaric acids, was purified with a 2400-fold enrichment and a 4% recovery. The enzyme showed specific activities (theoretical Vi., per milligram of protein) of 625 nanokatals (caffeoylglucaric acid forma...

Chlorogenic acid is a well-known antioxidant and has more isomers according to the difference in binding location and number of caffeic on quinic acid. In this study, we investigated and compared the profiles of antioxidant and DNA-protective activities of chlorogenic acid isomers including three caffeoylquinic acid isomers (3-O-caffeoylquinic acid, 3-CQA; 4-O-caffeoylquinic acid, 4-CQA; and 5-...

The aim of the study was to test the effect of three flavonoids on growth and survival of Helicoverpa armigera (Hüb) and Spodoptera litura (Fab.). A set of experiments were carried out with varying concentrations of three flavonoids namely chlorogenic acid, quercetin and rutin at 23±1oC on growth, development and mortality of larvae of pod borer Helicoverpa armigera and tobacco caterpillar Spod...

Parkinson's disease is a major neurodegenerative disease involving the selective degeneration of dopaminergic neurons and α-synuclein containing Lewy bodies formation in the substantia nigra. Although α-synuclein is a key molecule for both dopaminergic neuron death and the formation of inclusion bodies, the mechanism of α-synuclein induction of Parkinson's disease-related pathogenesis is not un...

the bioactivity of chemical extracts from silverleaf nightshade solanum elaeagnifolium cav. seeds and leaves were tested for herbicidal activities, through water and ethanol extracts, against portulaca oleracea l., corchorus olitorius l., convolvulus arvensis l.and echinochloa crus-galli (l.) found in most zea mays l.fields. characterization of the isolated constituents from ethanol extract was...

ABSTRACT The efficacy of gamma irradiation is well versed as a method of decontamination for food and herbal resources. In the present study, Cichorium intybus L. roots were irradiated at multiple doses of 1, 2, 4, 6, 8 and 10 kGy by a cobalt-60 irradiator. The irradiated and non-irradiated control samples were evaluated for total phenolic contents, chlorogenic acid assay, 2,2-diphenyl-1-...

INTRODUCTION Proximal spinal muscular atrophy (SMA) is a common autosomal recessively inherited neuromuscular disorder. It is caused by homozygous absence of the survival motor neuron 1 (SMN1) gene. SMN2, which modulates the severity of the disease, represents a major target for therapy. The aim of this study was to investigate whether SMN2 expression can be increased by caffeic acid, chlorogen...
