The complete chloroplast genome of Mangifera similis Blume (Anacardiaceae) from Bangka Island, Indonesia

Abstract

The chloroplast genome structures and its phylogenetic relationship were studied in Mangifera similis Blume from Bangka Island, Indonesia. The total size of the chloroplast genome was 158,977 bp, comprising large single copy (LSC) region (87,764 bp, 55.21 %), small single copy (SSC) region (18,423 bp, 11.59 %) and two inverted repeat regions (IRs) (26,395 bp, 16.60 %). As many as 132 genes (112 are unique) were recognized within the M. similis chloroplast genome, including 87 (80 are unique) protein-coding genes, 37 tRNAs (28 are unique), and eight rRNAs (4 are unique). Phylogeny analysis of the 22 species in the Anacardiaceae showed distinct genetic relationships between its six genera. The eight Mangifera species were divided into two groups, the first consisting of three subgroups of M. similis, M. odorata, M. longipes, M. persiciforma, and M. hiemalis, while in the second group, eight M. indica samples formed a monophyletic group which was sister to M. sylvatica and M. siamensis. The closest genetic relationships between M. similis and M. odorata need to be clarified using more Mangifera genome studies, especially those included in the IUCN Redlist. The first report of the M. similis cp genome will be useful for its phylogenetics, taxonomy, and conservation.
