Differential m6A methylomes between two major life stages allow potential regulations in Trypanosoma brucei
N6-methyladenosine (m6A) is the most prevalent mRNA modification in higher eukaryotes. Recent studies suggest that m6A has a regulatory role in mRNA degradation and translation initiation or efficiency, involving in cell fate determination in yeast, plants, and stem cells of mammalian. Trypanosoma brucei (T. brucei) regulates gene expression through post-transcriptional fashion, which heavily relies on mRNA cis-motifs. However, internal mRNA modification in T. brucei has not been reported yet. Here we using m6a-seq to present the methylome of m6A in both life stages of T. brucei. We identified 355 and 95 peaks in procyclic form and blood stream form trypanosomes respectively. A consensus motif of CAU was shared in both life stages of T. brucei. mRNA abundance of m6A-containing genes is higher in procyclic form and tend to be down-regulated in bloodstream form trypanosomes.
