Meristem culture

Vedclass · Answer

(A) The apical and axillary meristems of plants are generally free from viruses,even in infected plants. This is because the virus cannot replicate in the rapidly dividing meristematic cells due to high metabolic activity and the presence of specific antiviral compounds. Therefore,by culturing the meristem in a sterile medium (Meristem culture),scientists can regenerate healthy,virus-free plants from infected parent plants. This technique is widely used in agriculture for the clonal propagation of disease-free crops like banana,sugarcane,and potato.
