Fig. 3From: Genome-wide analysis of the rice PPR gene family and their expression profiles under different stress treatmentsSubcellular localization of a PPR gene in rice. a The results of subcellular localization of each subgroup and species using TargetP and Predotar on-line tools. Plastid in purple, mitochondria in green, endoplasmic reticulum (ER) in red, and other locations in blue. b Confocal scanning microscopy showing the subcellular localization of a PPR (LOC_Os10g34310) protein in mitochondria. Cells were treated with MitoTracker Red to detect mitochondria. GFP signals of fusion proteins localized in the chloroplasts of rice protoplasts. Bar = 5 μmBack to article page
