Transcript

  • 1. By Dr.U.Srinivasa, M.Pharm, Ph.D
  • 2. MUTATION IN PLANTS In molecular biology and genetics, mutations are changes in a genomic sequence: the DNA sequence of a cell's genome or the DNA or RNA sequence of a virus. These random sequences can be defined as sudden and spontaneous changes in the cell.
  • 3. Mutations are caused by radiation, viruses, and mutagenic chemicals, as well as errors that occur during meiosis or DNA replication.
  • 4. They can also be induced by the organism itself, by cellular processes such as hypermutation. On exposure to certain chemical, physical or physiological agents (mutagens) The different form of gene produced by mutation are called alleles. A cell or organism which shows effect of mutation is called mutant.
  • 5. CLASSIFICATION  They are mainly of three types: - Genomatic - Chromosome - Gene mutation
  • 6. EFFECTS OF MUTATION Mutation cause changes in chemical composition in medicinal plants apart from morphological and anatomical changes. On secondary metabolites: Solasodine content in solanum khasianum was increased by both radiation & chemical mutagens.
  • 7. Morphine content in opium was increased by chemical mutagens. Diosgenin content as well as tuber yield in dioscrea was reduced by radiation mutagens. Irradiation of poppy seeds with 14 CO a number of mutation was produced.
