title: Transcriptomic analysis reveals key genes related to betalain biosynthesis in pulp coloration of Hylocereus polyrhizus: Sample White
design: The same pulps from Guanghuahong were collected for RNA-Seq and data validation by RT-qPCR on the 28th (white pulp stage) and 42nd days (red pulp stage) after artificial pollination (DAAP) (Figure S1A and B) in October and November, 2013. The temperature was 16 ?-32 ? with relatively dry climate. Two transcriptome libraries were generated by pooling equal quantities of RNA from each of three fruit developmental stages.
