Genetic variation due to somaclonal variation in micropropagated plants is a beneficial phenomenon for crop improvement. Genetic integrity of the plants derived through micropropagation becomes crucial if genetic transformation studies have to be carried out. Somaclonal variation in tissue culture is a common phenomenon which makes it mandatory to check for genetic stability of plants. Hypocoty...

UNLABELLED While cocoa plants regenerated from cryopreserved somatic embryos can demonstrate high levels of phenotypic variability, little is known about the sources of the observed variability. Previous studies have shown that the encapsulation-dehydration cryopreservation methodology imposes no significant extra mutational load since embryos carrying high levels of genetic variability are sel...

Abstract Somaclonal variation during in vitro culture is often an undesirable phenomenon but may also be a source of genetic useful for breeders. The molecular mechanisms underlying this remain uncertain. In study, we analyzed the fruit transcriptome three independent cucumber lines using RNA-sequencing technology and performed extensive silico study to determine how somaclonal altered gene exp...
