Somatic fusion, also called protoplast fusion, is a type of genetic modification in plants by which two distinct species of plants are fused together to form a new hybrid plant with the characteristics of both, a somatic hybrid.
Plant tissue culture is defined as culturing plant seeds, organs, explants, tissues, cells, or protoplasts on a chemically defined synthetic nutrient media under sterile and controlled conditions of light, temperature, and humidity.
Meristem culture is defined as the tissue culture technique, which uses apical meristem with 1-3 leaf primordia to prepare clones of a plant by the vegetative propagation. This technique primarily involves the isolation of meristem by applying a V-Shape cut in the stem.
Micropropagation is the clonal propagation of plants in closed vessels under aseptic conditions. Inside the vessels, the plants are grown on culture media that contain nutrients and growth regulators, and are described as in vitro, which means 'in glass'. In contrast, soil-grown plants are described as in vivo.
Totipotency is defined in Wikipedia as the ability of a single cell to divide and produce all the differentiated cells in an organism, including extraembryonic tissues. Totipotent cells formed during sexual and asexual reproduction include spores and zygotes.
The pomato is a grafted plant that is produced by grafting together a tomato plant and a potato plant, both of which are members of the Solanum genus in the Solanaceae family.
Somaclones are the plants that are produced through tissue culture and are genetically identical to the parent plant from which they are produced and cultured.
