Recent progress in the understanding of tissue culture-induced genome level changes in plants and potential applications

Abstract: In vitro cell and tissue-based systems have tremendous potential in fundamental research and for commercial applications such as clonal propagation, genetic engineering and production of valuable metabolites. Since the invention of plant cell and tissue culture techniques more than half a century ago, scientists have been trying to understand the morphological, physiological, biochemical and molecular changes associated with tissue culture responses. Establishment of de novo developmental cell fate in vitro is… Show more

“…Early attempts to explain SV revealed the implication of chromosomal abnormalities (Karp 1991). Mutations affect the primary sequence of DNA and include numerical and structural chromosome changes (chromosome deletions, translocations and changes in ploidy), somatic recombination, point mutations, along with deletions and transpositions also occurring in mitochondrial and chloroplast genomes (Orton 1983;Karp 1991;Kaeppler et al 2000;Neelakandan and Wang 2012). All of these classes of mutations would be expected to give rise to stable sexually heritable variation (Orton 1983).…”

“…Somaclonal variation has been well characterized in a number of plants species, and generally results in the occurrence of unexpected phenotypes in progeny that arise from tissue culture (Kaeppler and Phillips 1993;Kaeppler et al 2000;Thorpe 2006;Rhee et al 2010;Miguel and Marum 2011;Neelakandan and Wang 2012). The rate of occurrence of aberrant phenotypes is higher than observed for normally propagated plants and appears to reflect a higher "mutagenic" rate during tissue culture.…”

“…Somaclonal variation induced by culture conditions limits the use of in vitro micropropagation, as it leads to changes in nuclear and cytoplasmic genomes and causes genetic differentiation of regenerated plants (D'Amato 1991; Larkin and Scowcroft 1981; Lee and Phillips 1988;Neelakandan and Wang 2012;Rodriguez-Enriquez et al 2011;Vazquez 2001;Wang and Wang 2012). Confirmation of the genetic identity with maternal material, and the genome size and reproductive normality of regenerated plants, is required before reintroduction (Nybom et al 2014;Ochatt et al 2011;Singh et al 2013;Thiem et al 2013;Thiem and Sliwinska 2003).…”
