RNA methylomes reveal the m6A-mediated regulation of DNA demethylase gene SlDML2 that is required for tomato fruit ripening


ABSTRACT: For exploring whether mRNA m6A modification participates in the regulation of tomato fruit ripening, we performed m6A-seq in three tomato fruit samples, including wild-type (WT) at 39 days post-anthesis (DPA) and 42 DPA, and Cnr mutant at 42 DPA, with three biological replicates. mRNA methylome analysis reveals that m6A methylation is a prevalent modification in mRNA of tomato fruit and the m6A sites are predominantly enriched in the stop codon and 3’ untranslated region, where m6A deposition has been proved to negatively correlate with gene expression. Hundreds of ripening-induced and ripening-repressed genes, including the SlDML2, were found to harbour changed m6A levels during fruit ripening or in the Cnr mutant, implicating the involvement of m6A modification in the regulation of fruit ripening.
