The following points highlight the eight main serological tests which helps in rapid diagnosis of plant viruses. The tests are: 1. Histochemical Test by Immunofluorescence 2. Agar Gel Double Diffusion Test 3. Direct Antigen-coated ELISA 4. Double Antibody Sandwich ELISA 5. Indirect Double Antibody Sandwich ELISA 6. Detection of Virus by Nucleic Acid Spot Hybridisation (NASH) using DNA Probe and [...]
Metabolism in any organism includes two processes anabolism and catabolism. These two processes include all the biochemical reactions of living organisms. Process # 1. Anabolism: It is a process in which essential biomolecules required for growth are generated by the utilization of energy. The chief biomolecules required are carbon like glucose, ribose, glycerol, pyruvate, etc. Some of the biomolecules act [...]
Learn the comparison between virusoids and satellites. In 1981 for the first time J.W. Randles and coworkers discovered the virusoids. These are the small circular RNAs which are similar to viroids but they are always linked with larger molecules of the viral RNA. Robertson (1983) have reported that virusoids are essential for replication of the large RNA and, therefore, form [...]
