The complete plastome sequences of Mangifera indica L. (Anacardiaceae)

Abstract

In this study, we determined the complete plastome sequence of Mangifera indica L. (Anacardiaceae) (NCBI acc. no. KX871231). The complete plastome is 157,780 bp in length, and consists of a large single copy of 86,673 bp and a small single copy of 18,349 bp, separated by two inverted repeats of 25,792 bp. The plastome contains 112 genes, of which 78 are protein-coding genes, 30 are tRNA genes, and four are rRNA genes. Sixteen genes contain one intron and two genes have two introns. The average A-T content of the plastome is 62.1%. The M. indica plastome has approximately 15 kb inversion between trnT-UGU and trnT-GGU. We identify a palindromic repeat of 18 bp (ATTCTTTTTTTTTTTTTT/AAAAAAAAAAAAAAGAAT) near the inversion breakpoints of M. indica plastome. Phylogenetic analysis revealed that M. indica is a sister group of Rhus chinensis with 100% bootstrap support. Anacardiaceae clade is a sister group of Boswellia sacra (Burseraceae) with 100% bootstrap support.
