    Spirulina is rich in protein, vitamins & minerals. 250 gram biomass of Methylophilus methylotrophus produces 25 tonne protein/day while cow of 250 Kg produces only 200 gm. protein/day. Common button mushrooms are a very rich source of vitamin D. A rice variety has been developed which is very rich in iron content.

    Genetic variation present among plant cells during tissue culture is called somaclonal variation. The term somaclonal variation is also used for the genetic variation present in plants regenerated from a single culture. This variation has been used to develop several
    useful varieties against resistance to diseases and pests, better yield, better quality etc.
