These plant cells can be cultured by either batch culture of suspension culture. Cell culture has a major advantage in the production of secondary metabolites. Requirements of a plant cell or tissue culture laboratories . The following are the requirements for plant tissue culture Callus cultures are often broadly classified as being either compact or friable. Friable calluses fall apart easily, and can be used to generate cell suspension cultures. Callus can directly undergo direct organogenesis and/or embryogenesis where the cells will form an entirely new plant The use of cell culture systems has a number of advantages in that they are usually fairly reproducible and can be standardized. Cells are easier to handle and store and one can use specific organ or species-specific cells. Specific questions as to toxic effect can be asked. Dose effects and the effects of specific metabolites can be determined In vitro dedifferentiated plant cell suspension cultures are more convenient for the large-scale production of fine chemicals in bioreactors and for the study of cellular and molecular processes.

Explain how suspension culture is prepared from callus

  1. Callus and suspension cultures of Trifolium repens (white clover) were established from seedlings. Protoplasts, isolated enzymatically from cell aggregates of suspension cultures, produced callus which was capable of in vitro differentiation into complete plants. Regenerated plants were nodulated if inoculated with Rhizobium trifolii Karyotypic stability (2n = 4x = 32) was maintained for 2 yr.
  2. Cells in suspension can exhibit much higher rates of cell division than do cells in callus culture. Thus, cell suspension offers advantages when rapid cell division or many cell generations are desired or when a more uniform treatment application is required2. The techniques of plant cell culture facilitate the rapid production of variant cell.
  3. Shoot tip culture tends to remain stable while those systems that utilize adventitious shoots or multiplication of callus, genetic variability is pronounced. Source of variability may be due to chimeral breakdown, aberrant cell division in callus or cell suspension, epigenetic effects and pre-existing genetic variability

Advantages and Disadvantages of Plant Tissue Culture

Cell Suspension. In culture methods, cell suspension refers to a type of culture where cells are suspended in a liquid medium. To obtain single cells, a friable callus (small tissue that falls apart easily) is put in agitated liquid medium (agitation allows for gaseous exchange unlike solid medium), breaking it up Callus cultures are established from suitable explants and multiplied through periodic sub-culturing. Similarly, cell suspension culture can be established by transferring actively growing callus to constantly agitated liquid medium and can be maintained or multiplied through periodic sub-culturing organic requirement of tobacco cultures. The medium consists of standard Murashige and Skoog (MS) basal salts supplemented with Linsmaier and Skoog vitamins. It is widely used for micro propagation, organ culture, callus culture and suspension culture. The formulation is a nutrient blend of inorganic salts,vitamins, carbohydrate and gelling agent C) Callus culture results when specific tissues are excised from the adult plant and allowed to form a structure known as a callus. The callus can then be used to generate a new tissue. D) Plant cell culture involves the dissociation of cells into a single cell suspension from where new plants can be generated
