Fig. 3: Relationship between RNA and protein abundance during osmotic stress.
From: Systems acclimation to osmotic stress in zygnematophyte cells
a Relative protein abundance at 25 hours compared to relative RNA abundance (integrated from 0 to 25 hours) for proteins showing a significant fold change (FDR < 0.05) in either salt or mannitol treatments relative to the control. The vertical lines from the trendline to the data points represent residuals. P-values on correlations were calculated based on stat_corr t-test. b Absolute protein abundance in Mesotaenium at 0, 6, and 25 hours plotted against absolute RNA levels at corresponding time points and replicates, with data points colored according to the size of the contig from which the protein-coding gene originates. The negative rank indicates the relative abundance of each protein, with –1 representing the most abundant protein, –100 the 100th most abundant, and so on. The white line represents the linear trendline. c Pearson correlation coefficients between relative (log2 fold change) protein abundance at 6 or 25 hours and corresponding relative RNA abundance. d Pearson correlation coefficients between absolute protein and RNA abundance at 6 or 25 hours.
