Figure 2. Comparative gene expression analysis of four mitochondrial protein genes in seedling leaves of CS under dehydration stress. Transcript accumulation levels of the AOX genes (WAOX1a and WAOX1c) and mitochondrial ribosomal protein genes (TaMRPL11 and WHLP) were analyzed by RT-PCR analysis. Cycle numbers of PCR are indicated on the right sides of electrophoregrams. As an internal control, a fragment of the wheat ubiquitin gene was amplified.
