What is Cellular Totipotency?
Totipotency is the capacity of a cell to differentiate into any cell type, making it capable of generating or developing into an entire organism. Each plant cell is a totipotent cell capable of producing a whole plant.
In other words, cellular totipotency is the capacity of a single cell to produce all kinds of cells and produce a whole organism when cultivated under adequate aeration and temperature conditions in a proper culture medium. Zygotes and spores are two examples of totipotent cells.
Professor Gottlieb Haberlandt, an Austrian botanist, first introduced the term totipotency and studied plant tissue culture. He said that because each live cell comes from a fertilised egg and is genetically encoded, it is capable of regenerating the entire plant body.
Cellular Totipotency in Culture
The fundamental principle of tissue culture is the controlled growth of a large number of cells in a sterile environment. The cells are taken from stems, roots, or other plant parts and are grown in a culture media containing hormones, vitamins, and minerals to promote cell division and growth. As a result, the cells in the culture develop into callus tissue, i.e. an unorganised proliferative mass of cells.
The constituent cells of a callus are totipotent. Given appropriate manipulations of the medium and the cultural environment, a callus tissue may therefore be totipotent in a broader sense, meaning that it may be able to regenerate back into a normal plant.
