Tissue culture rests on the principle of totipotency - a single plant cell, given a suitable medium and controlled conditions, can be induced to divide and regenerate an entire new plant, as F.C. Steward first demonstrated with carrot phloem cells.
Step 2. This means a rare or endangered plant can be multiplied starting from just a tiny amount of source tissue, without needing to harvest large quantities of plant material that a scarce population may not be able to spare.
Step 3. Tissue culture (micropropagation) can be carried out in any season and does not depend on the plant setting viable seed - a real advantage for endangered species that may produce little or no fertile seed, or whose seeds are difficult to germinate. …
