* Germplasm bank: A type of gene bank that specifically focuses on preserving the genetic diversity of plants.

These facilities play a crucial role in:

* Conservation of biodiversity: They protect endangered species and preserve genetic diversity for future generations.

* Agricultural research and development: Gene banks provide valuable resources for breeders to develop new crop varieties with desirable traits.

* Food security: They contribute to ensuring food security by safeguarding important genetic resources for food production.
