What is the Difference Between Micropropagation and Somatic Cell Hybridisation?
🆚 Go to Comparative Table 🆚Micropropagation and somatic cell hybridization are two different techniques used in plant biotechnology. Here are the key differences between them:
Micropropagation:
- Micropropagation is a technique used to produce a large number of genetically identical plantlets through tissue culture or somatic embryogenesis.
- The resulting plants, known as somaclones, are genetically identical to the parent plant, such as apple, tomato, or banana.
- This method is used for rapid propagation of plants, preservation of rare or endangered species, and production of disease-free plants.
Somatic Cell Hybridization:
- Somatic cell hybridization is a technique that fuses the protoplasts of two different plant cells, producing genetically dissimilar hybrids, such as the hybrid of potato and tomato known as Pomato.
- This technique allows manipulation of cellular genomes through protoplast fusion, resulting in novel interspecies or intergenic hybrids.
- Somatic cell hybridization is useful for studying and controlling gene expression, studying malignant transformations, studying viral replication, mapping genes or chromosomes, and producing monoclonal antibodies.
In summary, micropropagation is a technique used to produce genetically identical plantlets, while somatic cell hybridization is a method that fuses two different plant cells to create genetically dissimilar hybrids. Both techniques have their unique applications and advantages in plant biotechnology.
Comparative Table: Micropropagation vs Somatic Cell Hybridisation
Here is a table comparing micropropagation and somatic cell hybridization:
Feature | Micropropagation | Somatic Cell Hybridization |
---|---|---|
Definition | Micropropagation is a plant propagation technique that produces a large number of genetically identical plants. | Somatic cell hybridization is a hybridization technique that produces new hybrids through the fusion of protoplasts. |
Purpose | To propagate plants in a laboratory setting, often to preserve and propagate genotypes with superior germplasm. | To create novel interspecies or intergenic hybrids by manipulating cellular genomes through protoplast fusion. |
Technique | Involves the use of tissue culture methods to maintain and grow plant cells, tissues, or organs in a controlled environment. | Involves the fusion of protoplasts, selection of hybrid cells, and identification of hybrid plants. |
Fusion Type | N/A (no fusion involved) | Fusion of protoplasts or cybrids, which are cells formed by the fusion of a nucleus from one parent and cytoplasm from both parents. |
Applications | Micropropagation is used in plant breeding and tissue culture to create new plant varieties and preserve rare or endangered plant species. | Somatic cell hybridization is useful for creating novel interspecies or intergenic hybrids, which can be used in plant breeding and genetic research. |
In summary, micropropagation is a technique used for plant propagation, while somatic cell hybridization is a technique used to create novel hybrids through the fusion of protoplasts.
