Q. In protoplast fusion, the enzymes required are :

1. Cellulase, hemicellulase, pectinase
2. Pectinase
3. Ligase, hemicellulase
4. Hemicellulase

Solution : Correct option : A The enzymes required in protoplast fusion are cellulase, hemicellulase, and pectinase. Protoplast fusion is also known as somatic fusion in which genetic modification in plants is done. In the technique of genetic modification, two different species of plants are fused together to form a new hybrid plant bearing the characteristics of both the parent species. In the process, the enzyme cellulase digests the cellulose and removes the cell wall of one cell of each type of plant. The enzyme hemicellulase digests hemicellulose in the plant cell wall which is responsible for the rigidity of the plant cell. The enzyme pectinase breaks down the pectin which is holding cells together.
