Gene transcript features and sequence motifs contributing to different mRNA decay patterns. a-d A display of mRNA length, 5′ UTR length, 3' UTR length and number of introns for different gene types. “I”, “II”, “IV”, “R” and “A” represent type-I, −II, −IV, randomly selected genes and all genes, respectively. “***” indicates statistically significant difference at P-value < 0.001 (Student’s wilcox-test). e-h Enriched motifs (E-value < 0.001) in the 5' UTRs of type-I (e), type-II (f and g) and type-IV (h) genes
