Several key enzymes in lignin biosynthesis of Populus have been down-regulated by transgenic approaches to investigate their role in wood lignification and to explore their potential for lignin modification. Cinnamate 4-hydroxylase is an enzyme in the early phenylpropanoid pathway that has not yet been functionally analyzed in Populus . This study shows that down-regulation of cinnamate 4-hydro...

The broad study of histone deacetylases in chemistry, biology and medicine relies on tool compounds to derive mechanistic insights. A phylogenetic analysis of class I and II histone deacetylases (HDACs) as targets of a comprehensive, structurally diverse panel of inhibitors revealed unexpected isoform selectivity even among compounds widely perceived as nonselective. The synthesis and study of ...

The adsorption kinetics and orientational ordering of 4(')-n-octyl-4-cyanobiphenyl (8CB) liquid crystal films evaporated onto photosensitive poly(vinyl-cinnamate) (PVCN) substrates were investigated by surface optical second-harmonic generation. The adsorption rate of the first monolayer decreases with increasing degree of photochemical modification of the polymer. The in-plane orientational an...

Neuroleptic activity of methanolic extract of Benincasa hispida was assessed using apomorphine induced cage climbing model and catalepsy test in mice. Methanolic extract showed significant reduction in apomorphine induced cage climbing activity at 600 mg/kg and catalepsy in mice .The phytochemical analysis of methanolic extract showed presence of phenolic compounds and triterpene saponins, whic...

The fairly recent detection of a variety of anions in the interstellar molecular clouds have underlined the importance of realistically modelling the processes governing their abundance. To pursue this task, our earlier calculations for the radiative electron attachment (REA) rates for C4H , C6H , and C8H − are employed in the present work, within a broad network of other concurrent reactions, ...

“Hungariana,” “Beauty Zest,” and “Home Flavor” hot pepper plants (Capsicum annuum L. var. annuum) were grown with an ample or a limited water supply. The fruits of plants in the water deficit treatment were small, had a proportionally heavier placenta and had a higher concentration of capsaicin. The concentration of capsaicin in the placenta of “Beauty Zest” fruits in the water deficit treatmen...

Sequestration, into the ethyl trans-cinnamate, over control QQ hairpencils, of the behaviourally most active courtship pheromone component, in male Grapholita rnolesta (Busck 1916) results in an increased mating success attracted to ethyl cinnamate-treated dd moved significantly faster than 99 attracted to control Cfcf Since control dd that were successful at coupling on average took more attem...
