Many somatic plant cells, including some fully differentiated types (e.g. leaf mesophyll),provided they contain intact nuclear, plastid and mitochondrial genomes, have the capacity to regenerate into whole plants. This phenomenon is totipotency.Totipotent cells from plants have been used in tissue-culture techniques to produce improved plant materials that are pathogen-free and disease-resistant. Totipotent cells fromanimals are … Read more
