The complete chloroplast genome sequence of (Araceae).

is native to North America and northern Asia, with significant potential for industrial wastewater remediation. The complete nucleotide sequence of the chloroplast genome (cpDNA) was determined. The cpDNA is a circular molecule of 166,606 bp and containing a pair of inverted repeats (IRs) measuting 31,663 bp each. These IRs are flanked by a small single-copy region of 13,542 bp and a large single-copy region of 89,738 bp. The chloroplast genome of consisted of 112 unique genes, including 78 protein-encoding genes, 30 tRNA genes, and four rRNA genes. The phylogenetic analysis utilizing cpDNA provided a well-supported resolution of the relationships among subfamilies within the Araceae family. Our findings indicated a close relationship between and a clade consisting of , , and . The availability of the complete chloroplast genome sequence of presents valuable data for future phylogenetic investigations within the Lemnaceae family.
