cucumber mosaic virus (cmv) is one of widely-spread viruses of plants with the broadest host range encompassing over 1200 species. one major limiting factor for detection of the virus is unavailability of the virus-specific antibodies especially in developing countries. recombinant dna technology facilitates antibody preparation without requiring special equipment. in this study, coat protein (...

in order to  study the effect of beet mosaic virus on sugarbeet seed yield, an isolate of beet mosaic virus was collected from sugarbeet fields in karaj and biologically was purified by inoculation on chenopodium amaranticolor and propagated on beta vulgaris cv. cicla under greenhouse conditions. the infected sap was inoculated on leaves of  sugar beet  7233 variety at  two stages, after and be...

Apium graveolens (celery) is an edible and traditionally medicinal plant that is used worldwide, among others for the treatment of hypertension. Combining celery with antihypertensive drugs can affect the pharmacodynamics and pharmacokinetics of the latter drugs. The aim of the study is to assess the effects of administrating the celery extract on captopril pharmacokinetics. Sprague-Dawley stra...

Tobacco Mosaic Viruses, Crystallization, Phase Transitions, Light Diffraction, Crystal Structure, Model Calculations Iridescent gels of the common, tomato mosaic, para-tobacco mosaic, ribgrass mosaic, sunnhemp mosaic, and cucumber 4 tobacco mosaic virus strains were prepared using the purification method of Boedtker and Simmons (J. Amer. Chem. Soc. 1958). Macrocrystals which were stable for man...

Mosaic is a common disease symptom caused by virus infection in plants. Mosaic leaves of Tomato mosaic virus (ToMV)-infected tobacco plants consist of yellow-green and dark green tissues that contain large and small numbers of virions, respectively. Although the involvement of RNA silencing in mosaic development has been suggested, its role in the process that results in an uneven distribution ...

Human cytochrome P450 (CYP) 2A6 participates in the metabolism of nicotine and precarcinogens, thus the deliberate inhibition of CYP2A6 may reduce cigarette consumption and therefore reduce the risk of developing the types of cancer associated with smoking. The inhibitory effects and mechanisms of celery (Apium graveolens) extract on mouse CYP2A5 and human CYP2A6 activity remain unclear. These ...

Samsun NN tobacco cells were transformed with chimeric genes for pathogenesis-related (PR) proteins derived from genomic (PR-1a, GRP) or cDNA (PR-S) clones under the transcriptional control of the cauliflower mosaic virus 35S promoter. Regenerated plants were assayed by RNA and protein gel blotting, and plants showing high specific expression of the inserted genes were selected for self-pollina...
