The complete chloroplast genome of Pandanus amaryllifolius Roxb. ex Lindl. (Pandanaceae) and its phylogenetic relationship

Pandanus amaryllifolius of Pandanaceae, a plant native to Southeast Asia, has been domesticated for its health benefits and aromatic leaves. It is also used for phytoremediation and soil rehabilitation. However, genetic studies of this species are limited. This study aims to expand its genomic information by assembling and characterizing the complete chloroplast genome of P. amaryllifolius. The chloroplast genome, which was 157,839 bp long, contains a total of 133 genes, including 87 protein-coding (CDS), 38 tRNA, and eight rRNA genes. The overall G/C content was 37.7%. A phylogenetic analysis using 79 shared unique CDS revealed a monophyletic relationship in Pandanales. Based on the limited sampling size, Pandanus amaryllifolius was the first to diverge in Pandanaceae. The genomic data will be useful for future phylogenetic and evolutionary studies of Pandanaceae.
