Table 2 Median percentages of reads from B73 and Mo17 that mapped to UTRs relative to exons among genes upregulated by B73 or Mo17 eQTL

From: Zea mays RNA-seq estimated transcript abundances are strongly affected by read mapping bias

  B73 reads Mo17 reads All readsc
B73 + eQTL 17.1a 14.3 15.7
Mo17 + eQTL 13.7b 13.1 13.4
  1. aAmong genes upregulated by B73 alleles at cis eQTL, the percentage of reads that mapped to UTRs was significantly higher for reads derived from B73 alleles than for reads derived from Mo17 alleles. Wilcoxon signed rank test, V = 7,544,600, P < 2.2e-16
  2. bAmong genes upregulated by Mo17 alleles at cis eQTL, the proportion of reads that mapped to UTRs was also significantly higher for reads derived from B73 alleles than for reads derived from Mo17 alleles. Wilcoxon signed rank test, V = 1,324,300, P = 1.1e-8
  3. cThe percentage of all reads irregardless of allelic origin that mapped to UTRs was significantly higher for genes upregulated by B73 alleles than genes with upregulated by Mo17 alleles. Wilcoxon rank sum test, W = 25,439,952, P < 2.2e-16
