Tissue culture is a method of clonally propagating a plant of interest. Plant tissues naturally contain meristematic cells which have not yet become organ specific, meaning they can become root, shoot, or leaf cells depending on the environment. By adjusting the ratio of plant hormones in your growth media, namely auxins and cytokinins, you can control what kind of tissue the meristematic cells begin to form. This allows for the generation of multiple new plants from a single cutting, allowing for exponential growth of your plant of interest.
Pictured above are new shoots emerging from cotyledon and leaf cuttings of Stanleya pinnata and Stanleya elata in the family Brassicaceae.
