TF prediction and APA analysis. a Number and family of top 29 TFs predicted by SMRT. b Distribution of the number of poly(A) sites per gene. c Nucleotide composition around poly(A) cleavage sites. The relative frequency of a nucleotide is shown as a function of genomic position across all poly(A) cleavage sites detected in our data. d MEME analysis of an over-represented motif at 25-nts upstream of the poly(A) site in red clover transcripts
