Study offers new insights how the plant tips stay free of virus

Plants are able to keep growing indefinitely because they have tissues made of meristems--plant stem cells--which have the unique ability to transform themselves into the various specialized cells that make up the plant, dividing whenever appropriate and producing new cells of whatever type as needed.
