[Experiments with Bacillus thuringiensis protoplasts. I. Isolation of protoplasts and their reversion to bacillary
Abstract:
A method for protoplastization of crystal- and spore-forming Bacillus thuringiensis bacterian and consequent cell wall regeneration on a solid hypertonic medium is presented. Up to 50% of the protoplasts prepared were viable and formed colonies under special conditions; at the same time, less than 0,01% of the cells treated with lysozyme were resistant to the osmotic shock; bacterial autolytic system takes part in protoplasts formation. Electron microscopic studies of protoplasts and cells confirm the fact of cell wall removal and support the proposed mechanism of protoplast formation.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
