Abstract
Oxalis triangularis, a perennial Oxalidaceae ornamental with biological functions, had its full cpDNA sequenced: a 152,115 bp circular genome with two 25,436 bp inverted repeat regions, an 83,309 bp large single-copy region and a 16,934 bp short single-copy region. The overall GC content was 36.48%. A total of 109 genes were annotated, including 76 protein-coding genes, 29 tRNA genes and 4 rRNA genes, all starting with AUG. Furthermore, 70 simple sequence repeats were also found. Phylogenetic analysis groups it with 10 Oxalis species, closely related to O. latifolia, O. drummondii, and O. corymbosa, providing resources for its molecular identification and evolutionary studies.
