Somaclones can be defined as: |
They have the capacity to generate a whole plant from any explant. They are genetically identical to the original plant. They are genetically modified pest resistant plants. They are the plants, infected with virus. |
They are genetically identical to the original plant. |
The correct answer is Option (2) → They are genetically identical to the original plant. Plant tissue culture is based on the special property of plant cells to generate a whole plant, called totipotency. The plant part used in tissue culture is called explant. The nutrient medium provides a carbon sources such as sucrose. inorganic salts, vitamins, amino acids and growth regulators like auxins cytokinins etc. Propagation of thousands of plants in very short duration through tissue culture is called micropropagation. Each of these plants will be genetically identical to the original plant i.e., they are somaclones. |
