Question

Vidya got a plant that was affected by a viral disease. Her objective is to raise a disease-free plant from this infected plant through tissue culture. Which part of the plant should be selected as the explant?

Answer 1

The explant should be selected as the apical tip or the bud. This region is composed of the meristematic tissues. These cells are in rapid deciding phase and hence they are not infected by any bacterial or viral agent. These tissues help in the development of the disease-free plants.
