The complete chloroplast genome of two related fig species Ficus squamosa and Ficus heterostyla

The Ficus squamosa and Ficus heterostyla share an undescribed pollinating fig wasp Ceratosolen sp. in Xishuangbanna region, which constitutes the most excellent model to study the role of convergent evolution and hybridization in the species-specific fig-wasp mutualism. The plastomes were 160,350 bp for Ficus squamosa and 160,300 bp for F. heterostyla, both in length with the typical quadripartite structure. In the two genomes, the LSC region was 88,615 bp (F. squamosa) and 88,535 bp (F. heterostyla), the SSC region was 20,071 bp (F. squamosa) and 20,101 bp (F. heterostyla), and the IR regions of both figs were 25,832 bp. They contained 113 unique genes, including a set of 78 protein-coding genes, 30 transfer RNA (tRNA) genes, four ribosomal RNA (rRNA) genes, and one pseudogene (infA). Phylogenetic analysis based on the complete chloroplast (cp) genomes within the Ficus genus suggests that they are closely related sister species.
