<p><strong>Background:</strong> Plant tissue culture has been shown to be an efficient technique for the propagation of diverse <em>Agave</em> species using different <em>in vitro</em> regeneration processes. However, it demonstrated that genetic changes can occur in plants regenerated under these schemes, also called somaclonal variation. <strong&gt...

The instability of in vitro cultures may cause genetic and epigenetic changes crops called somaclonal variations. Sometimes, these produce beneficial effects; for example, they can be used breeding programs to generate new cultivars with desirable characteristics. In this article, we present a systematic review designed answer the following question: How does variation contribute plant improvem...

Somaclonal variation for morphological traits was studied in both control and mutagen (chemical and physical) treated progenies of two varieties of Solanum viarum. The SC1, SC1M1 (first generation following tissue culture) and SC2, SC2M2 (second generation) of both 2n and 4n varieties on field evaluation showed bidirectional variation for plant height, plant spread, number of flowers and fruits...

There is great interest in the phenotypic, genetic and epigenetic changes associated with plant in vitro culture known as somaclonal variation. In vitro propagation systems that are based on the use of microcuttings or meristem cultures are considered analogous to clonal cuttings and so widely viewed to be largely free from such somaclonal effects. In this study, we surveyed for epigenetic chan...
