In plants buckling, puckering and blistering symptoms are produced by Correct Answer Viruses

In plants buckling, puckering and blistering symptoms are produced by Viruses.
Plant viruses are made up of a strand of nucleic acid (DNA or RNA) surrounded by a protein sheath.
Local symptoms are physiological or structural changes within a limited area of host tissue, such as leaf spots, galls, puckering, buckling and cankers.
Symptoms of virus infection include necrotic spots, abnormal dark green and light green mosaic and mottling of leaves, growth distortion, stunting, ring patterns or bumps on plant foliage, and abnormal flower coloration and formation.
