Establishment of the cell lines with plant regeneration ability and low ploidy level in Dianthus acicularis with the aid of flow cytometry analysis

  • Published : 2005.11.02


Efficient plant regenerationsystem from cell suspension cultures was established in D. acicularis (2n = 90) by monitoring ploidy level and visual selection of the cultures. The highly regenerable cell lines selected maintained original ploidy level and consisted of compact cell clumps with yellowish color and relatively moderate growth, suggesting that it is possible to select visually the highly regenerable cell lines with the original ploidy level. All the regenerated plantlets from the highly regenerable cell cultures exhibited normal phenotypes and no variations in ploidy level were observed by flow cytometry (FCM) analysis.
