RT-qPCR analysis of the Arabidopsis Twinkle homologue gene expression relative to organellar localized DNA polymerases in various tissues. The relative abundance of Twinkle and the two organellar DNA polymerases (Polymerase gamma I and Polymerase gamma II) is shown. Expression varied among selected organs with highest expression in the shoot apex. The relative expression of Twinkle follows the expression levels of DNA polymerase gamma I. Error bars indicate SEM of three replicates. The Y axis indicates relative expression (log2) normalized to nuclear actin gene expression. Inflor, inflorescence.
