What is protoplast regeneration?
The protoplasts isolated from the light condition were regenerated into plants, but the effect of light or dark condition during digestion on the regeneration capacity was not investigated. Agitation of the enzymatic solution on a gyratory shaker during the protoplast digestion can increase the protoplast yields.
What is protoplast transfection?
Protoplast transfection refers to the introduction of exogenous nucleic acids into protoplasts mediated by polyethylene glycol (PEG) or electroporation [53–55]. PEG-mediated transfection method is commonly used to introduce DNA or RNA into protoplasts.
What is the significance of protoplast?
Protoplasts can be used to study membrane biology, including the uptake of macromolecules and viruses . These are also used in somaclonal variation. Protoplasts are widely used for DNA transformation (for making genetically modified organisms), since the cell wall would otherwise block the passage of DNA into the cell.
What is protoplast in biotechnology?
Abstract. Plant protoplasts (“naked” cells) provide a unique single cell system to underpin several aspects of modern biotechnology. Major advances in genomics, proteomics, and metabolomics have stimulated renewed interest in these osmotically fragile wall-less cells.
What is protoplast in plants?
Protoplasts are spherical naked plant cells produced by the removal of the cell wall with digestive enzymes (Fig. 1). They are usually derived from either leaf tissue or from cell suspension cultures and have been isolated from a wide variety of plant species.
Where is protoplast found?
The cytoplasm is the initial component of protoplasm, which is found between the cell membrane and the cell nucleus in a eukaryotic cell.
Why is protoplast important in genetic recombination?
Protoplast fusion allows us to produce hybrids with combined genomes and increased ploidy levels, as opposed to the combination of meiotically reduced genomes found in sexual hybridization or the limited gene transfer that is achieved with genetic transformation.
How is protoplast formed?
Protoplasts are isolated cells produced by removing the surrounding cell wall either by mechanical means or by the use of cell wall degrading enzymes. Removal of the cell wall leaves the protoplast surrounded by the plasmalemma membrane.
Who discovered protoplast?
Dujardin
Dujardin in 1835 discovered protoplasm but in 1839 it was J.E. Purkinje who coined the word protoplasm. Protoplasm is the colourless material comprising of all the living components of the cell.
