Ribosomal proteins (RP) genes decrease their TE upon differentiation. Expression profiles for the RP genes are shown in T. cruzi epimastigotes (E) and metacyclic trypomastigotes (MT). Upper panel: (A) Bar plot of the E stage transcriptome and translatome levels for the RP and for all T. cruzi genes. Each bar marks the population median while the whiskers represent the interquartile range. (B) Bar plot of the translation efficiency (TE) for the RP and for all T. cruzi genes. Statistically significant differences among populations are indicated by asterisks (Wilcoxon p < 0.05). Lower panel: (C) and (D) are the same type of bar plots as A and B respectively, but for the MT stage. Note the decrease in translation efficiency of RP (D) as a result of a major decrease in RP translation (C). Y-axis scales in figures A and C are different.
