The complete chloroplast genome of a wild onion species Allium monanthum (Alliaceae)

Allium monanthum is a typical spring ephemeral, appearing above ground for only 2-3 weeks in late March to early or late April. Here, Illumina pair-end reads of this species was used to record the complete chloroplast (cp) genome. The circular genome with 154,804 bp in length contains a pair of inverted repeats (IRs) of 24,551 bp, separated by a large single-copy region (LSC) of 83,701 bp and a small single-copy region (SSC) of 21,867 bp. It harbors 132 genes, including 86 protein-coding genes, 38 transfer RNA genes, and 8 ribosomal RNA genes. Phylogenetic analysis supported that the A. monanthum was located in the crown of the Alliaceae, and was closely clustered with other Allium species.
