An epigenetic view of plant cells cultured in vitro: somaclonal variation and beyond

An epigenetic view of plant cells cultured in vitro: somaclonal variation and beyond.

Epigenetic mechanisms are highly dynamic events that modulate gene expression. As more accurate and powerful tools for epigenetic analysis become available for application in a broader range of plant species, analysis of the epigenetic landscape of plant cell cultures may turn out to be crucial for understanding variant phenotypes. In vitro plant cell and tissue culture methodologies are import...

Somaclonal variation: a morphogenetic and biochemical analysis of Mandevilla velutina cultured cells.

Cell cultures of Mandevilla velutina have proved to be an interesting production system for biomass and secondary metabolites able to inhibit the hypotensive activity of bradykinin, a nonapeptide generated in plasma during tissue trauma. The crude ethyl acetate extract of cultured cells contains about 31- to 79-fold more potent anti-bradykinin compounds (e.g., velutinol A) than that obtained wi...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Somaclonal variation on in vitro callus culture potato cultivars

Hortic. bras., v. 22, n. 2, abr.-jun. 2004 C potato (Solanum tuberosum L.) is one of the most important vegetable crop of Brazil and the world’s fourth most important crop (Solomon-Blackbourn & Barker, 2001). In 2002, Brazil produced 3,126,411 t of potato with an average yield of 19,4 kg/ ha (IBGE, 2002). Potato is a tetraploid species and the use of its botanical seeds in commercial cultivatio...
