The complete chloroplast genome of Typha angustifolia and its phylogenetic position in Typhaceae

Typha angustifolia, commonly known as narrowleaf cattail, is a marginal, semi-aquatic, herbaceous perennial species with both ecological and edible values. In this study, the complete chloroplast (cp) genome of T. angustifolia was assembled using the next-generation sequencing technology. The whole cp genome was 161,597 bp in length, consisting of a large single copy (LSC, 89,119 bp) and a small single copy (SSC, 18,550 bp) separated by two copies of inverted region (IR, 26,964 bp). The genome encoded 113 unique genes, including 79 protein-coding genes, 30 tRNA genes, four rRNA genes, with 19 duplicated genes in the IR regions. Phylogenetic analysis showed that T. angustifolia is sister to Typha orientalis in the family Typhaceae. The cp genome of T. angustifolia is reported for the first time, which will provide essential and important genetic resources for future phylogenetic investigation within the genus Typha.
