Correlations of mRNA features with poly(A)-tail length in wild type and with the extend of poly(A)-tail length change in paps1 mutants versus wild type.

(A) Correlation of estimates of poly(A)-tail length in wild-type seedlings with the mRNA half-life. Pearson correlation coefficient and p-value is given. (B,C) Correlations of estimates of the change of poly(A)-tail length in paps1-1 mutants versus wild type with the estimated change in total transcript abundance between the two genotypes (B), and the mRNA half-life (C). Purple symbols in (B) represent the transcripts with a significant tail-length change after multiple-testing correction; purple font in (B) shows the correlation between tail-length and abundance change for the 97 significant transcripts, blue font for all transcripts.
