Fungal Toxin as Potential Tool for in vitro Selection and Regeneration of Resistant Plants

Namrata Shanu Gupta and Krishnendu Acharya    

Abstract: Fungal pathogens impose a foremost threat to crop productivity. So, efforts to develop resistance against these pathogens in plants are of great importance. In recent years in vitro selection has emerged as a viable tool for developing resistant germ plasm. Resistant variants can be acquired by applying selective agent such as fungal toxins in the tissue culture media. In toxin based in vitro selection, explants that can withstand selection pressure can survive and only those cells are selected for regeneration. The resistance trait appearing in the regenerated plants may be genetically stable and useful in the crop improvement. Henceforth, the present review focuses on implementation of fungal toxin as a potential tool for in vitro selection and recent progress made towards the development of resistant germ plasm through this technique.
