List any four applications of tissue culture.

Explanation

**Step-by-Step Text Solution:**

1. **Production of Large Numbers of Identical Individuals**: Tissue culture allows for the rapid multiplication of plants, producing a large number of genetically identical individuals from a single parent plant. This is particularly useful in agriculture and horticulture for the mass production of desired plant varieties.

2. **Conservation of Plant Biodiversity**: Tissue culture techniques are employed to conserve endangered plant species. By culturing plant tissues, it is possible to preserve genetic material and maintain biodiversity, which is crucial for ecological balance and future research.

3. **Selection of Mutations**: Tissue culture can facilitate the selection and propagation of desirable mutations. Through controlled environments, scientists can induce mutations and select for traits that may be beneficial, such as disease resistance or improved yield.
