Although a plant is infected with a virus, the meristem (apical and axillary) is free of virus. Hence one can remove the meristem and grow it in vitro to obtain virus free plant. In micropropagation genetically identical plants are produced known as somaclones. Plant cell without cell wall is known as protoplasm. Pomato is a somatic hybrid between potato and tomato and does not have all the desired combination of characters for its commercial utilization.
