Study Notes
Plant Tissue Culture
- A fundamental ability of plants in tissue culture is totipotency, the ability to form a whole plant from a single cell.
Hormones in Plant Tissue Culture
- Auxin is the hormone responsible for root development in plant tissue culture.
- Cytokinin is the hormone responsible for shoot development in plant tissue culture.
- Abscisic acid is the hormone that activates the ABFS-ABRE plant stress pathway in rice.
Plant Culture Media
- The basic components of plant culture media include water, inorganic salts, sugars, amino acids, and vitamins.
Types of Plant Tissue Culture
- Agrobacterium-mediated transformation is a type of plant tissue culture used for DNA transformation and production of hybrid plants.
- Somatic embryogenesis is a type of plant tissue culture used for the production of artificial seeds.
- Hairy root culture is a type of tissue culture ideal for obtaining secondary metabolites.
- Somatic embryogenesis is a type of plant tissue culture used for the production of bioplastics and anti-cancer drugs.
Plant Tissue Culture Terms
- De-differentiation is the term used to describe the capacity of mature cells to return to a meristematic condition in plant tissue culture.
- Protoplasts are "naked" plant cells without cell walls.
- Somatic embryogenesis is the process of producing embryo-like structures using somatic tissues.
- Encapsulation is the process of artificially encapsulating somatic embryos in a protective coating.
Conservation and Applications
- Cryopreservation is a technique used for the conservation of endangered/rare species.
- Plant tissue culture is used for the production of artificial seeds, bioplastics, and anti-cancer drugs.
