Abstract

Biological diversity provides the variety of life on the Earth and can be defined as the variability among and between the living organisms and species of surrounding ecosystems and ecological complexes of their life support. It has been estimated that one third of the global plant species are threatened in different level according to the International Union of Conservation of Nature (IUCN).The major threat to rapid loss and extinction of genetic diversity due to habitat destruction, pollution, climate change, invasion of exotic species, human population pressure, ever increasing agricultural pressure and practices, life style change etc. are well-known. Biodiversity conservation is a global concern. All member states of the Convention on Biological Diversity (CBD) took measure to preserve both native and agricultural biodiversity. The global concern of biodiversity conservation initiated either by in situ or ex situ methods. In situ methods protect both plants and their natural habitat. On the other hand, ex situ methods involves preservation and maintenance of plant species or plant parts (such as seeds, cuttings, rhizomes, tubers etc.) outside their natural habitat for the purpose of developing seed banks or more preciously gene banks following classical / advanced methods of plant propagation. Classical methods of plant propagations have certain limitations in terms of rapid production of plants or plant propagules and their long term conservation. So, the biotechnological methods such as plant tissue culture, plant cell culture, anther culture, embryo culture etc. are quite applicable and useful techniques for ex situ conservation. On the other hand, the production of superior quality seeds has enhanced by the application of plant biotechnology. So, plant biotechnology offers new means of improving biodiversity conservation rather than threatening biodiversity in various ways.
