Figure 2.

Macroarray analysis comparing plastid transcript accumulation in light-grown wild-type and pap7-1 Arabidopsis seedlings. Given is the transcript accumulation in wild-type (top panel) and mutant (bottom panel) seedlings both for sense (blue bars) and antisense (red bars) transcripts. Hybridization signals were normalized to the total signal intensity of the membrane and are given as arbitrary units in the left margin. Genes are labeled at the bottom of each panel according to accepted nomenclatures. Sequence of genes corresponds to their organization on the plastome separated between inner strand (left parts) and outer strand of the plastome (right parts). High transcript accumulation of PEP-dependent transcripts in wild type is highlighted by green boxes. High transcript accumulation of NEP-dependent transcripts in the pap7-1 mutant is highlighted by yellow boxes. WT, wild type.
