Structural characterization and phylogenetic analysis of the chloroplast genome of var. balansae (gagnep.) N. Jacobsen 1991.

is a popular ornamental aquatic plant for aquarists, although only six species are found in China. Destruction of the natural habitats of for human activities has led to a decline in its numbers. In this report, we sequenced and annotated the chloroplast genome for the first time. Results showed that the length of the chloroplast genome was 182,935 bp and the GC content was 34%. The chloroplast genome encoded 137 genes, including 92 encoded protein genes, 37 tRNA genes, and 8 rRNA genes. Phylogenetic analysis supported the the monophyletic nature of the genus and indicated that it was the first species to be differentiated in the chloroplast genome of and formed a separate branch. These findings offer valuable genomic resources for comparative studies in and Araceae, thereby aiding genetic diversity and phylogenetic analyses.
