Therefore, to be used in industrial applications, they must be cultured in vitro. Pharmacological use – Lichens are symbiotic associations composed of fungal (mycobiont) and algal (photobiont) partners. They produce secondary metabolites […]

Plant tissue culture

Plant tissue culture is a technology widely used in fast propagation of cash plants. It requires strict aseptic techniques to ensure no contamination occurs. The principle of tissue culture is cell totipotent, in another word, every plant cell has the potential to develop into a whole plant. However practically actively growing tissue such stem tips are more easily to manipulate. You don’t want to pick an old leaf tissue to carry out tissue culture. But […]
