(Submitter supplied) m6A is a ubiquitous RNA modification in eukaryotes. Transcriptome-wide m6A patterns in Arabidopsis have been assayed recently. However, m6A differential patterns among organs have not been well characterized. The goal of the study is to comprehensively analyze m6A patterns of numerous types of RNAs, the relationship between transcript level and m6A methylation extent, and m6A differential patterns among organs in Arabidopsis.

(Submitter supplied) Methylation of carbon 5 in cytosine (5-methylcytosine; m5C) is a well-characterized DNA modification, and is also predominantly reported in highly abundant noncoding RNAs, such as rRNA and tRNA, in both prokaryotes and eukaryotes. However, the distribution and biological functions of m5C in plant mRNAs remain largely unknown. Here we develop an m5C RNA immunoprecipitation followed by deep sequencing approach (m5C-RIP-seq) to achieve transcriptome-wide profiling of RNA m5C in Arabidopsis thaliana. more...

However, owing to methodological limitations, the transcriptome-wide distribution of this mark has remained largely unknown. We have previously established RNA bisulfite sequencing as a method for the analysis of RNA (cytosine-5) methylation patterns at single-base resolution. Furthermore, next-generation sequencing has provided opportunities to establish transcriptome-wide maps of this modification. more...

(Submitter supplied) In the present study, we discover the presence of m2A in chloroplast rRNA and tRNA, as well as cytosolic tRNA, in multiple plant species. We identify six m2A-modified chloroplast tRNAs and two m2A-modified cytosolic tRNAs across different plants. Furthermore, we characterize three Arabidopsis m2A methyltransferases—RLMNL1, RLMNL2, and RLMNL3—which methylate chloroplast rRNA, chloroplast tRNA, and cytosolic tRNA, respectively. more...

(Submitter supplied) 5-methylcytosine (m5C) is a prevalent base modification in tRNA and rRNA but it also occurs more broadly in the transcriptome, including in mRNA. In pursuit of potential links of m5C with mRNA translation, we performed polysome profiling of human HeLa cell lysates and subjected RNA from resultant fractions to efficient bisulfite conversion followed by RNA sequencing (bsRNA-seq). Bioinformatic filters for rigorous site calling were devised to reduce technical noise. more...

(Submitter supplied) We report the identification and quantification of Watson-Crick modifications in tRNA and rRNA through the use of high throughput sequencing. We apply the recently published DM-tRNA-Seq method to generate demethylase treated and untreated 293T samples, and using computational methods we are able to flag sites using a modification index. This index allows us to generate site-resolved information about modification that we can use to identify and quantify Watson-Crick face modifications in tRNA and rRNA. more...

(Submitter supplied) Despite its biological importance, transfer RNA (tRNA) could not be adequately sequenced due to the abundant presence of post-transcriptional modifications and extensive structure that interfere with cDNA synthesis and adapter ligation. We achieve efficient and quantitative tRNA sequencing by removing base methylations using engineered demethylases and using a highly processive thermo-stable reverse transcriptase without the need for adapter ligation (DMTRT-tRNA-seq). more...

(Submitter supplied) N7-methylguanosine (m7G) is a positively charged, essential modification at the 5′ cap of eukaryotic mRNA, regulating mRNA export, translation, and splicing. m7G also occurs internally within tRNA and rRNA, but its existence and distribution within eukaryotic mRNA remain to be investigated. Here, we show the presence of internal m7G sites within mammalian mRNA. We then performed transcriptome-wide profiling of internal m7G methylome using m7G-MeRIP sequencing (MeRIP-seq). more...

(Submitter supplied) In order to fulfil a wide range of cellular functions, RNA molecules contain, in addition to the four canonical bases, a large number of chemically modified structures. Among those, the methylation of carbon-5 of cytosines (m5C) is an abundant, widespread mark in different classes of RNAs. m5C is catalysed by DNMT2 and by seven members of the NSUN family of enzymes. While some m5C-methyltransferases have been studied individually and implicated in phenotypes observed in organisms ranging from yeast to humans, it remains unclear how the m5C methylome acts to sustain development in homeostasis and stress. more...

For each, we detect ‘signature’ base mismatches (for m5C and m1A), or 1-2 base deletions (for pseudouridine) structurally explained by ribose ring-opened pseudouridine-mono-bisulfite adducts.  Our profiles for pseudouridine reveal clear signatures at known sites in tRNAs and rRNAs, and provide hundreds of new targets in non-coding RNAs and mRNAs. more...

(Submitter supplied) Kelp are the largest photosynthetic organisms in the ocean with tissue differentiation and complex life cycles. Other multicellular organisms with similar complexity such as plants and animals are well known to posses epigenetic mechanisms such as DNA methylation to control development and morphogenesis. Despite plant-like body plans and the presence of different life-cycle stages, the kelp species Saccharina japonica has only a very low level of DNA methylation, yet we have found strong evidence for differential methylation of regulatory elements and protein-coding genes which seem to contribute to the formation of life-cycle stages, tissue differentiation, growth and halogen metabolism. more...
