Elaeis guineensis (oil palm) accounts for a large and increasing proportion of the world's cooking oil production. Cloning via somatic embryogenesis results in a somaclonal variant known as mantled which produce fruit with little to no oil yield. The mantled phenotype is believed to be epigenetic in nature. We performed RNA-Seq on developing flower and fruit samples of normal and mantled oil palm to characterize their transcriptomes. We present expression data for all transcripts in normal and mantled flower and fruit samples. Many genes are differentially expressed, including several from pathways that may be the cause of the mantled phenotype if disrupted, such as genes involved in primary hormone responses, DNA replication and repair, chromatin remodeling and a gene involved in RNA mediated DNA methylation. In addition, the gene expression data for developing flower and fruit will serve as a valuable resource for oil palm genetics and genomic studies.
