Characterization of the complete plastid genome of lop-sided onion Allium obliquum L. (Amaryllidaceae)

The complete chloroplast genome sequence of Allium obliquum was determined by Illumina single-end sequencing. The complete plastid genome was 152,387 bp in length, containing a large single copy (LSC) of 81,588 bp and a small single copy (SSC) of 18,059 bp, which were separated by a pair of 26,370 bp inverted repeats (IRs). A total of 134 genes were annotated, including 83 protein coding genes, 38 tRNA genes, eight rRNA genes, and five pseudogenes. The overall GC contents of the plastid genome were 36.8%. Unlike A. cepa (onion) and A. sativum (garlic), A. obliquum encodes a functional intact infA gene.
