Role of biotechnology in Pharmacognosy
Start with the big picture
Plant tissue culture grows plant cells, tissues, or organs aseptically on nutrient media under controlled conditions. It can provide climate-independent biomass and a consistent raw-material source. Micropropagation multiplies elite or endangered genotypes while maintaining genetic fidelity. Callus, suspension, and hairy-root cultures offer ways to produce secondary metabolites without field cultivation; elicitation, precursor feeding, and biotransformation can further shape production. The topic also covers metabolic engineering and synthetic biology, alongside process scale-up using immobilized cells and bioreactors. Genetic diversification methods, such as mutagenesis and polyploidy induction, support screening for useful chemotypes, while cryopreservation and molecular identification methods contribute to conservation and quality control. Together, these approaches link laboratory cultivation with industrial phytochemical production.
