A sugarcane has been affected by virus. How can a virus free cane be developed from it ? Explain the procedure.

Answer» The virus free sugarcane can be developed by the process of tissue culture where in the whole plant is regenerated from explants. i.e., any part of a plant grown in a test tube under sterile conditions in special nutrient media. The technique makes use of the property of totipotency and the fact that the meristem (apical and axillary) of the sugarcane plant is free of virus. Hence, the meristem can be removed and grown In-Vitro to get disease free plant.
