Complete chloroplast genome sequence and phylogenetic analysis of a wild species of abiu fruit, Pouteria caimito (Ruiz & Pavon.) Radlk

摘要

Abiu fruit (Pouteria caimito [Ruiz & Pavon.] Radlk.) is endemic to the Amazonian region of South America, the fruit is also called yellow star apple, blueberry pie fruit and cauje. In this study, the chloroplast genome sequence of P. caimito was assembled and characterized using Illumina sequencing. The whole chloroplast genome of the wild species of abiu fruit is 158,916?bp, composed of four regions: a large single-copy region (88,096?bp) and a small single copy (18,620?bp) region, separated by two inverted repeat regions (26,100?bp), and the GC content is 36.83%. A total of 133 genes were annotated, including 88 that encoded proteins, eight that encoded rRNA genes and 37 that encoded tRNA genes. A maximum likelihood tree was constructed based on the sequences of chloroplast genome, the results showed that the wild species of P. caimito is the most closely related to Pouteria campechiana . This study provided abundant genomics data for the research and development of P. caimito .
