Figure 5

Diagrammatic illustration of correlations between the tissue culture-induced various types of genetic/epigenetic alterations and altered expression of genes involved in DNA repairing and DNA methylation, in calli and regenerants, respectively. A total of 41 genes were analyzed (detailed in Figure 4) and only those manifesting correlations with at lease one type of genetic or epigenetic alterations in calli or regenerants were shown. Pearson correlation analysis was performed and detailed in Additional file 10. The blue and black lines refer to significant correlations at levels of P < 0.05 and P < 0.01, respectively.
