Characterization of Fusarium species associated with tobacco diseases in Northwestern Argentina
(2018-08)
Tobacco (Nicotiana tabacum L.) production is centred in the northwestern region of Argentina (NWA), where the incidence of root rot and stem diseases has increased considerably in recent years. This study aimed to analyse ...
Transgenic expression of tobacco mosaic virus capsid and movement proteins modulate plant basal defense and biotic stress responses in Nicotiana tabacum
(2012)
Plant viruses cause metabolic and physiological changes
associated with symptomatic disease phenotypes. Symptoms involve direct and indirect effects, which result in disruption
of host physiology. We used transgenic ...
Identification and characterization of key circadian clock genes of tobacco hairy roots: putative regulatory role in xenobiotic metabolism
(Springer Heidelberg, 2018-01)
The circadian clock is an endogenous system that allows organisms to daily adapt and optimize their physiology and metabolism. We studied the key circadian clock gene (CCG) orthologs in Nicotiana tabacum seedlings and in ...
Potato Virus X Coat Protein Fusion to Human Papillomavirus 16 E7 Oncoprotein Enhance Antigen Stability and Accumulation in Tobacco Chloroplast
(Springer, 2009-11)
Cervical cancer linked to infection with human papillomavirus (HPV) is the third cause of cancer-related death in women. As the virus cannot be propagated in culture, vaccines have been based on recombinant antigens with ...
Determination of cadmium in tobacco by solid surface fluorescence using nylon membranes coated with carbon nanotubes
(Elsevier Science, 2013-05)
A new methodology based on fluorescent signal enhancement of o-cresolphthalein (o-CPT) for traces of cadmium determination is proposed. The dye was retained on membrane filters in the presence of a micellar surfactant ...
Lead monitoring and control in tobacco products and E-cigarettes by molecular fluorescence
(Elsevier Science, 2019-06)
A new methodology for lead traces determination has been developed based on the quenching effect on fluorescent emission of the complex formed by the metal with 8‑hydroxyquinoline and o-phenanthroline at λ em = 365 nm (λ ...
Over-expression of potato virus X TGBp1 movement protein in transgenic tobacco plants causes developmental and metabolic alterations
(Elsevier France-editions Scientifiques Medicales Elsevier, 2004-09)
Transgenic Nicotiana tabacum plants expressing the TGBp1 movement protein of potato virus X (PVX) were studied to investigate the effects caused by this protein on plant physiology and development. TGBp1 caused consistent ...
Expression of the minor isoform pea ferredoxin in tobacco alters photosynthetic electron partitioning and enhances cyclic electron flow
(American Society Of Plant Biologist, 2013-02)
Ferredoxins (Fds) are ferrosulfoproteins that function as low-potential electron carriers in plants. The Fd family is composed of several isoforms that share high sequence homology but differ in functional characteristics. ...
Modeling tobacco mosaic virus proliferation in protoplasts
(North Atlantic University Union, 2016-06)
The tobacco mosaic virus (TMV) is one of the most studied viruses. It is frequently used as a model in the research of virus-host interactions. The interest in understanding the mechanism of its proliferation stems basically ...
Impact of phenol on the glycerophospholipid turnover and potential role of circadian clock in the plant response against this pollutant in tobacco hairy roots
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2020-06)
Glycerophospholipids (GPLs) from cell membranes (CM) are a proper source for the synthesis of lipid messengers able to activate signal pathways that will define the plant survival under changing and stressful environmental ...
