Association of m6A with APA usage in B73. A, The number of genes defined in each category in the corresponding analysis. B, Proportion of m6A-modifed transcripts within transcripts with (left) or without APA usage (right). P values were calculated using the Fisher’s exact test. C, Proportion of transcripts containing APA usage within m6A-methylated (left), and nonmethylated transcripts (right). P values were calculated using the Fisher’s exact test. D, Integrative Genomics Viewer plots of two examples representing m6A located in the proximal (left) or distal (right) APA. The arrows indicate the gene direction from the 5′ to 3′ end.
