Effect of anti-ethylene compounds on isoenzyme patterns and genome stability during long term culture of Moringa oleifera

2018-09-30 13:21:15 Keywords micropropagation, Moringa, Molecular markers, Isoenzymes, Gene expression, anti-ethylene,
Effect of anti-ethylene compounds on isoenzyme patterns and genome stability during long term culture of Moringa oleifera
Multiplication of Moringa oleifera shoots on MS medium supplemented with 2.5 μM BAP for 3 weeks resulted in shoot vitrification which led to chlorosis, retardation of shoot formation, reduction in shoot length, necrosis of shoot tips and formation of friable calli on the base of cultured explants. Vitrification symptoms decreased when MS medium containing 2.5 μM BAP in combination with ... Read more

New insights in the acute toxic/genotoxic effects of CuO nanoparticles in the in vivo Drosophila model.

2018-09-30 14:49:43 Keywords CuO-NPs, Drosophila melanogaster, Duox, Hml genes, PPO2, Upd3, Gene expression, genotoxicity, internalization,
New insights in the acute toxic/genotoxic effects of CuO nanoparticles in the in vivo Drosophila model.
Metal oxide nanoparticles are highly reactive from the biological point of view and, for this reason, it exists important reservations in regard human health impact. We used Drosophila as a promising in vivo model to diagnose the biological effects of copper oxide nanoparticles (CuO-NPs). Due to the potential role of ions release the effects of CuO-NPs were compared with those ... Read more

In vitro propagation, microtuberization, and molecular characterization of three potato cultivars

2018-09-19 14:37:52 Keywords auxins, cytokinins, Gene expression, micropropagation, RAPD, Solanum nigruom,
In vitro propagation, microtuberization, and molecular characterization of three potato cultivars
Sprouts of potato tubers were excised from the three potato cultivars Agria, Hermes, and Spunta, sterilized and subjected to shoot formation and propagation on Murashige and Skoog (MS) medium supplemented with 1 mg dm-3 6-benzylaminopurine (BAP) + 0.5 mg dm-3gibberellic acid. Shoots were rooted on MS medium supplemented with 1 mg dm-3 indole-3-butyric acid. To increase shoot vigour prior tuber ... Read more

Shoot regeneration and isoenzyme expression of Moringa oleifera under the influence of salt stress

2018-09-23 12:56:18 Keywords Gene expression, Moringa,
Shoot regeneration and isoenzyme expression of Moringa oleifera under the influence of salt stress
Shoot regeneration and isoenzyme expression of Moringa oleifera under the influence of cytokinin type and different concentrations of NaCl were studied. Cotyledonary nodal segments obtained from in vitro grown seedlings (initial culture) and nodal segments obtained from their regenerants (first subculture) were subjected to shoot formation on MS medium supplemented with 0.56 mg/l BAP or KIN, for three weeks each. ...

Association of MIR-499a expression and seed region variant (rs3746444) with cardiovascular disease in Egyptian patients

2018-09-12 16:42:58 Keywords myocardial infarcti, MIR-499a, MIR-499a, gene, Coronary artery disease, myocardial infarction, polymorphism, Gene expression,
Association of MIR-499a expression and seed region variant (rs3746444) with cardiovascular disease in Egyptian patients
BACKGROUND: Circulating microRNAs could be powerful markers of acute myocardial infarction (MI) and its functional genetic variants could increase susceptibility to cardiovascular disease (CVD). The current study aimed to quantify the microRNA (miR)-499a levels in serum of MI patients compared to hypertensive and healthy subjects and to investigate the association of its A/G variant rs3746444 with CVD in a sample ...
