  1. Identification of differentially expressed contigs between tribenuron-methyl susceptible (SD8) and resistant (N11) flixweed populations by RNA-Seq, and the expression levels of the contigs were validated using qRT-PCR with RNA-Seq samples (n = 2) and additional samples from resistant N11 (n = 12) relative to susceptible SD8 (n = 11). Fold-change in gene expression (2-△Ct) was calculated relative to the susceptible samples, where △CT = [CT target gene-CT mean of two internal control genes]. P-value of <0.05, 0.01, 0.001 is indicated by *, **, and ***, respectively (from SPSS analysis)
  2. a Padj, adjusted P-value, the differentially expressed contigs were fliterred by Padj < 0.05 from DESeq analysis
  3. b FPKM, fragments per kilobase of transcript sequence per millions base pairs sequenced
  4. c Inf indicates readcount of SD8 samples = 0 in RNA-Seq
