Which specific technique is used to obtain virus-free plants from an infected mother plant?

  1. Explant culture
  2. Somatic embryogenesis
  3. Meristem tip culture
  4. Cell suspension culture
Show answer and explanation

Correct answer: Meristem tip culture

The apical meristem is usually free of viruses due to the lack of vascular connection and high metabolic activity. Culturing only the tiny meristematic dome allows for the regeneration of healthy, virus-indexed plants.
