Which part of the plant is best suited for making virus-free plants and why?

(N/A) Apical and axillary meristems of plants are best suited for making virus-free plants.
In a diseased plant,these meristematic regions remain free from viral infection even if the rest of the plant is infected.
This is because the rate of cell division in the meristem is very high,which prevents the virus from establishing itself in these tissues.
Scientists remove the apical or axillary meristems of the infected plant and grow them in vitro (tissue culture) to obtain healthy,virus-free plants.
This technique has been successfully used to produce virus-free plants of banana,sugarcane,and potato.
