Q. Assertion (A):Thermotherapy combined with meristem (shoot-tip) culture is more effective than either method alone for eliminating certain plant viruses.

Reason (R): Some viruses such as Potato virus S (PVS) and Potato virus X (PVX) can only be eliminated when heat treatment is followed by shoot-tip culture, and larger shoot tips taken from heat-treated plants show better survival.
