Figure 4.

Protein abundance of non-plastidic proteins in chloroplast fractions after heat stress. (a) The number of plastid (p -localized (dark blue) or non-plastidic (np) proteins (light blue; based on SUBA) found in all, or in at least 8, 7, 6 or 5 chloroplast samples is shown. Yellow crosses indicated the ratio between plastid localized proteins and non-plastidic proteins. (b) The log₂(LFQ) for the indicated protein group was normalized to the lowest log₂(LFQ) value found for the indicated group in any of the samples. The value is plotted for the wild type (blue), ppi1 (magenta) or toc64-1 (yellow). The dotted frames indicate the 99% confidence interval of the median of the log₂(LFQ) values normalized to the lowest median (control, HS-I, and HS-II) of all non-plastidic proteins in one sample.
