Supercoiled mitochondrial DNAs from plant tissue culture cells

Supercoiled mitochondrial DNAs from plant tissue culture cells.

Supercoiled mitochondrial DNA (mtDNA) has been isolated in preparative amounts from five different plant species and compared on agarose gels. The gels reveal considerable mtDNA size heterogeneity within each species as well as substantial differences in the range and frequency of the mtDNA size classes among the different plants. The two lowest size classes of three of the plants have been ext...

History of plant tissue culture.

Plant tissue culture, or the aseptic culture of cells, tissues, organs, and their components under defined physical and chemical conditions in vitro, is an important tool in both basic and applied studies as well as in commercial application. It owes its origin to the ideas of the German scientist, Haberlandt, at the beginning of the twentieth century. The early studies led to root cultures, em...

Elicitors in Plant Tissue Culture

Plants or plant cells in vitro, show physiological and morphological response to microbial, physical or chemical factors which are known as ‘elicitors’. Elicitation is a process of induced or enhanced synthesis of secondary metabolites by the plants to ensure their survival persistence and competitiveness. The application of elicitors, which is currently the focus of research, has been consider...
