Copy numbers of chromosome 4 and chromosome 5 of the KRA mt genome. Copy numbers were estimated with qPCR relative to mt 18S rDNA (a), or relative to nuclear 18S rDNA (b). Statistically significant differences were detected between leaves and flower buds when mt 18S rDNA was used as a reference (p < 0.023 for chromosome 4, p < 0.000001 for chromosome 5), but not with nuclear 18S rDNA as a reference. B – flower buds, L – leaves, F – females, H - hermaphrodites
