qPCR evaluation of RNA-seq data from Foc-infected banana cultivars. a Comparison of gene expression values obtained by qPCR and RNA-seq. Fold-change values were calculated for 30 banana genes from the infected sample comparing to the mock-inoculation sample and 10 Foc genes from the infected sample comparing to from the infected BX at 27 h. b Principal Components Analysis (PCA) displaying the intrinsic biological variation among banana samples. The result confirms the clear distinction between the transcriptomes of infected and healthy plants. Circle, mock-inoculated BX at 27hpi (BX-MK27h); green cross, mock-inoculated BX at 51 hpi (BX-MK51h); diamond, infected BX at 27 hpi (BX27h); square, infected BX at 51 hpi (BX51h); purple cross, mock-inoculated NK at 27 hpi (NK-MK27h); purple triangle, mock-inoculated NK at 51 hpi (NK-MK51h); blue triangle, infected NK at 27 hpi (NK27h); and asterisk, infected NK at 51 hpi (NK51h)
