Totipotency is the unique feature of plant cells where every single cells has biological potential to develop normal root, shoots and embryoids, which ultimately forming a plant. The term totipotency is defined as the capability of each living cell to carry out independent development to regenerate into a complete plant, provided with suitable conditions [1]. Many research has been done using tissue culture as a medium to study multicellular organism, because it is rather difficult when using the organism as biological units of study.
