The plastid genome characteristics of a moth orchid (Phalaenopsis wilsoniii, Orchidaceae)

Phalaenopsis wilsonii is a typical deciduous species in the horticulturally well-known genus, Phalaenopsis. Tshi species is belonging to the section Aphyllae in moth orchid, and is endemic to South China. Although the Aphyllae section display the deciduous feature that is unique in this genus, their genetic information is still insufficient and limited them as breeding parent in moth orchid. Here, we reported and characterized the complete chloroplast genome for Phalaenopsis wilsonii. We found the total size of the chloroplast genome was 145,373 bp, constituting of a large single copy (LSC) region (84,996 bp), a small single-copy region (10,668 bp) and two inverted repeats (IRs) regions (24,855 bp). Based on homologous searching on database, we annotated 76 protein-coding genes, 38 tRNA, and 8 rRNA. The phylogenetic reconstruction revealed that P. wilsonii show the closest relationship with P. lowii within subgenus Parishianae.
