Fig. 8: Quantitative RT–PCR analysis of 16 randomly selected genes.

A, B Expression levels of differentially expressed genes (DEGs) in MMC-stage ovules as determined by RNA-seq and real-time qRT–PCR. A Upregulated genes in MMC-stage ovules. B Downregulated genes in MMC-stage ovules. C–D Expression levels of DEGs in PMC-stage anthers as determined by RNA-seq and real-time qRT–PCR. C Upregulated genes in PMC-stage anthers. D Downregulated genes in PMC-stage anthers. The table shows the RPKM values from RNA-seq, and the histograms display the relative expression levels of the genes in different pineapple tissues as determined by qRT–PCR
