Abstract:
Opuntia sulphurea Gillies ex Salm-Dyck 1834 (Cactaceae) acts as an invasive species due to its ability to survive in various environments. In this study, we assembled the complete chloroplast (cp) genome of Opuntia sulphurea, which was 122,740 bp in length. The genome contained 100 genes, including 65 protein-coding genes, 31 tRNA genes and four rRNA genes. The base composition of the chloroplast genome was 32.11% A, 17.74% G, 18.34% C, and 31.80% T, resulting in an overall G + C content of 35.39%. A phylogenetic analysis across 23 species in Caryophyllales demonstrated a close relationship between Opuntia sulphurea and Opuntia quimilo.

Two models describe the mechanism of precursor recognition and entry across the outer membrane through the TOC complex. Model 1 suggests the newly synthesized precursor binds to the TOC receptor 159 and forms a complex.
