Alpinia nigra draft genome and insights into the genetic basis of flexistyly

Our aim was to investigate the genetic basis of a floral dimorphism termed flexistyly. We produced a draft genome using Illumina 250 bp paired-end reads and used a Pool-seq approach to investigate the allele frequency differences between the two morphs (anaflexistyly and cataflexistyly). The anaflexistylous pool was prepared with DNA from 51 individuals and the cataflexistylous pool with DNA from 63 individuals in equimolar concentrations. The sequencing data was generated using Illumina 150 bp paired-end reads. Note that all the samples were collected from the same population.
