Molecular insight into somaclonal variation phenomena from transcriptome profiling of cucumber (Cucumis sativus L.) lines

Plant Cell Tissue and Organ Culture, 2021
Somaclonal variation during in vitro culture is often an undesirable phenomenon but may also be a source of genetic variation useful for breeders. The molecular mechanisms underlying this phenomenon remain uncertain.

Producing a superior genotype from agria potato cultivar using somaclonal variation

, 2021
This study was performed to produce a superior genotype from Agria potato cultivar using somaclonal variation. Two leaf and meristem explants in combination with four doses of 2,4-D (0, 2, 3 and 4 mg / l) were used for callus induction in a factorial ...

Somaclonal variation as a tool for temperate fruit breeding

Acta Agriculturae Slovenica, 1999
Somaclonal variation involves all forms of phenotypic and genotypic variation generated by in vitro growth. It can provide useful genetic variation for plant improvement, especially in vegetatively propagated crops such as fruits.

Shoot organogenesis in leaf explants of Hydrangea macrophylla ‘Hyd1’ and assessing genetic stability of regenerants using ISSR markers [PDF]

, 2011
For the first time, an in vitro regeneration protocol of Hydrangea macrophylla 'Hyd1' was developed. Effects of different plant growth regulators (PGRs) on shoot regeneration were investigated jointly with selecting optimal basal media and cefotaxime ...

Epigenetic changes and their relationship to somaclonal variation: a need to monitor the micropropagation of plantation crops.

Functional Plant Biology, 2020
Chromatin modulation plays important roles in gene expression regulation and genome activities. In plants, epigenetic changes, including variations in histone modification and DNA methylation, are linked to alterations in gene expression.
