Dictionary of botanic terminology - index of names

  A plant that contains a mixture of tissues from two or more genetically different cells or tissues in the same part of a plant.  

These different tissues can be spontaneously mutated cells of the host organism or cells from a different organism or species produced as a result of organ transplant, grafting (Graft chimera), artificial fusion of unlike tissues or genetic engineering.  A chimaera show variegation when some of the plant’s tissues lose the ability to produce chlorophyll so that this tissue lacking of chlorophyll (usually white or  yellow) contrasting with the normal green tissue. Because the chimera is due to the presence of two kinds of plant tissue, propagating the plant must be by a vegetative method of propagation that preserves both types of tissue in relation to each other.
