Fig. 6From: Genome-wide identification, characterisation and functional evaluation of WRKY genes in the sweet potato wild ancestor Ipomoea trifida (H.B.K.) G. Don. under abiotic stressesComparison between quantitative RT-PCR data and RNA-seq data. Relative expression of the 11 selected ItfWRKYs was analysed by qRT-PCR. The GAPDH transcript levels were used for normalisation. The y-axis represents the relative expression of the fold. Error bars indicate standard deviation. RNA-seq and qRT-PCR data are represented by black and grey bars, respectivelyBack to article page
