Complete chloroplast sequence of Fenerivia ghesquiereana (Annonaceae): a rare and endemic tree from Madagascar.

ABSTRACT: Fenerivia ghesquiereana (Cavaco & Keraudren) R.M.K. Saunders (Annaonaceae) is a rare and endemic tree restricted to the warm tropical forests of Madagascar, a major global hotspot for biodiversity. Species in the genus are mostly restricted to a thin belt along the eastern edge of the island and remain under intense pressure due to deforestation for logging, mining and slash-and-burn agriculture ('tavy'), despite national pledges to curb biodiversity losses and increase park protection to combat illegal logging and poaching. Here we report the complete chloroplast genome sequence of this species to support ongoing efforts to complete the (sub-)tribal classification of the family. The chloroplast sequence of F. ghesquiereana was 160,194 bp in length, including two inverted repeat regions of 26,093 bp, a large single-copy region of 89,041 bp and a small single-copy region of 18,967 bp. A total of 160 genes were annotated, of which 115 are coding, 37 are tRNA genes, and eight are rRNA genes. The overall GC content was 39%; this was higher in the IRs (43.4%) when compared to the LSC (30.7%) and the SSC (33.9%) regions. A Maximum Likelihood phylogenetic analysis with a selection of other plastomes in Annonaceae placed F. ghesquiereana as sister to Meiogyne hainanensis (Merr.) in subfamily Malmeoideae.
