The most common way is carried by bugs, especially plant sucking bugs like aphids. They can also be spread plant to plant on uncleaned pruners or knives used on the plants.
Plant viruses have special proteins that allow them to enlarge the plasmodesmata and effect entry in this way.
plasmodesmata, the cytoplasmic connections that penetrate the walls between adjacent plant cells
Plant viruses have a difficult time entering the cells they infect partly because plant cells are surrounded by tough cell walls that viruses alone cannot break through; however, once inside a plant they can multiply and spread rapidly.
The lytic cycle causes destruction of infected cells and their membrane. A virus that uses a lytic cycle reproduces itself or makes copies that are sent back into the environment and they are called virulent viruses.
Viruses can reproduce very quickly. When reproducing they enter a living cell and they inject their genetic material.

Major differences are- 1)most plant viruses are with plus sense s.sRNA although there are exeptions whereas animal viruses can be d.s/s.sDNA or RNA viruses..2)plant virus always needs insect vector,whereas animal virus may enter body through various means.3)plant virus always needs a mechanical damage in cell wall of plant to enter.
capsids prevent viral infections apex they stop viral infections from reproducing

There are plant viruses that cause strange color patterns. Tulips can get tulip color breaking virus.
