Summary of transcript changes in aox1a:rpoTmp under standard growth conditions compared with the wild type (Col-0) and overlap with single mutants. A, The number of transcripts that increased (red) or decreased (blue) in abundance in aox1a:rpoTmp and the overlap with aox1a or rpoTmp. Next to this, a Pageman visualization of the functional groups over- or underrepresented in the genes that were differentially expressed exclusively in the aox1a:rpoTmp mutants, where unique_up indicates the exclusively up-regulated genes and unique_down indicates the exclusively down-regulated genes. B, A customized MapMan overview showing changes in transcripts encoding mitochondrial proteins in aox1a:rpoTmp compared with the wild type (Col-0). The genes encoding proteins involved in glycolysis are also shown outside the mitochondrion. WT, Wild type; TOM, translocase of the outer membrane; SAM, sorting and assembly machinery of the outer membrane; BCS1, cytochrome bc1 synthesis; cyt C, cytochrome c; UCP, uncoupling protein; UT, untreated; VDAC, voltage-dependent anion channel; Pol, polymerase.
