Identification of RNAs Associated with CP29A and CP31A in Chloroplast Stroma.

The enrichment ratios (pellet F635/supernatant F532) were normalized between three assays involving wild-type stroma, one control assay with stroma from the corresponding null mutants (from cp29a [A] or cp31a [B] seedlings, respectively), and one control assay involving wild-type stroma, but assayed with preimmune serum of the corresponding antibody. The median normalized values for replicate spots from the mutant data and from the control assays were plotted according to chromosomal position. The data used to generate these graphs are provided in Supplemental Data Set 1 online.
