Abstract:
This study presents the complete sequence of Vanilla pompona chloroplast genome. This 148,009 bp long genome consist of 107 genes out of which 30 of them are tRNA, 4 rRNA. Fairly long inverted repeat regions (IR) and large single-copy (LSC) of length 29,807 and 86,358 bp, respectively, were detected. This means an exceptionally short single-copy (SSC) region with only 2037 bp. This truncation of the SSC is due to multiple translocation of ndh genes to the mitochondrion as in majority of the Orchidaceae and especially in the genus Vanilla. The phylogeny presented here meaningfully places Vanillon within the orchid family.
