Fig. 6

Expression profiles of 17 NBS-encoding genes in four pear accessions at enlarged stage by RT-qPCR analysis and RNA-seq data. The relative expression levels of each individual NBS-encoding genes were normalized by the Pyrus GAPDH gene. The expression level of PyW14 sample was used as a reference (relative expression level = 1). The letter “r” represents the correlation between RNA-seq data and RT-qPCR data. Bars represent mean relative expression level of genes (rose red: PyW14, purple: PyW13, blue: PyL2, cyan: PyI1); lines represent value of RPKM. Mean relative expression value and corresponding standard deviation were calculated by the three replicates of relative expression value. Four pears included Asian wild (PyW13,14) and cultivated (PyL2,PyI1) accessions. Left y-axis represents the relative expression level and right y-axis represents RPKM values
