The genome-scale gene expression profiling and network analysis provide a broad foundation for the functional analysis of genes involved in pineapple flower and fruit development.. Floral transcriptomes in pineapple

The availability of a high quality genome sequence for pineapple makes it an excellent model for studying fruit and floral organ development. In this study, we sequenced 27 different pineapple floral samples and integrated nine previously published RNA-seq datasets to generate tissue- and stage-specific transcriptomic profiles. Pairwise comparisons and weighted gene co-expression network analysis were used to identify modules of co-expressed genes and the hub genes of tissue-specific networks.
