From: Comparison of mitochondrial gene expression and polysome loading in different tobacco tissues
Northern blot analysis of mitochondrial RNA abundance in tobacco organs. a The analyzed tissues are indicated above the blots. Three mitochondrial genes (cox1, atp9 and rps10) were analyzed to confirm the pattern of mitochondrial mRNA abundance observed through mitochondrial microarray analysis. Equal loading of RNA was checked through 18S rRNA hybridization. The blots are representatives for three independent replicates. b Signal intensities relative to the 18s rRNA control from the Northern blots presented in part a of this figure. Pixel intensity values as determined using ImageJ were used to calculate the ratios
