Characterization of the complete chloroplast genome sequence of (L.) A. J. Scott 1978 (Amaranthaceae) and its phylogenetic analysis.

, an annual potherb belonging to the family Amaranthaceae, has been widely used in traditional Chinese and Japanese medicine for over 2000 years. Herein, we presented its complete chloroplast. The chloroplast genome sequence was 151,278 bp in length with a 36.6% content of GC. The genome showed the typical quadripartite structure, comprising a pair of inverted repeat (IR) regions (24,353 bp) separated by a large single-copy (LSC) region (84,067 bp) and a small single-copy (SSC) region (18,505 bp). This chloroplast genome harbored 133 predicted genes, including 88 protein-coding genes, 37 transfer RNA (tRNA) genes, and eight ribosomal RNA (rRNA) genes. The phylogenetic analysis indicated that was closely related to . This newly sequenced chloroplast genome not only enhances our understanding of the genome of but also provides valuable insights for the evolutionary study of the family Amaranthaceae.
