Somaclonal Variation

The terminally differentiated cells in plants, such as pith cells and cortical cells, often exhibit cytological and genetic changes that go unnoticed and do not cause abnormalities in the plant because they do not form part of the germ line cells. However, in cultures these cells may be induced to undergo redifferentiation and express the inherent variability at the whole plant level. Additional variations may be induced by the culture conditions. While some of these variations are transient physiological and developmental changes (e.g., rejuvenation), others are a result of epigenetic changes which can be relatively stable but are not transmitted to the seed progeny. Some other in vitro induced variations are caused by specific genetic changes or mutations and are transmitted to the progeny. The variations recovered from somatic tissue cultures, referred to as somaclonal variation, have been in many cases processes into new improved cultivars of crop plants.
