ANSWER :-

  1. The first gene that needs to be introduced belongs to cyanobacteria and some in plants which are involved in the synthesis of an enzyme called chlorophyll F synthase which in turn is being activated under the effect of an external light source in order to initiate formation and buidup of respective chlorophyll molecules for the process of photosynthesis. This has been tracked to the upregulation of certain genes which are associated with the upregulation of the synthesis of chlorophyll molecules in response to light mainly the gene chlorophyll synthase.
  2. The second gene is R-gene which is responsible for playing a pivotal role in the process of enhancing the resistance of a plant towards a pathogenic microbe. One such gene is the N-gene which has been isolated from the Tobacco plant and is stated to interact with the nucleotide sequence of the Tobacco Mosaic Virus thereby generating resistance within the plant against this viral agent.
  3. The third gene is the gene which encodes from the protein Cytosolic ascorbate peroxidase 1 which is involved in plants response to external injury or stress by means of mediating the process of signal transduction wherein certain regulatory molecules are being activated one of which is the reactive oxygen species which in turn is involved in mediating stress associated response. Their activity is associated with the Rapid Alkalinization Factor like protein encoded by RALF gene whose activity is upregulated during parasitic infections and certain stress factors.
