In virus-infected plants, the meristematic tissues in both apical and axillary buds are free of virus because

1. the dividing cells are virus resistant

2. meristems have antiviral compounds

3. the cell division of meristems are faster than the rate of viral multiplication

4. viruses cannot multiply within meristem cell(s)
