Genomic changes associated with somaclonal variation in banana (Musa spp.) [PDF]

, 2007
The molecular basis of somaclonal variation is not precisely known, but both genetic and epigenetic mechanisms have been proposed. The available evidence points toward the existence of labile portions of the genome that can be modulated when the cells ...
