Abstract:
Bixa orellana is a small tree known for its red, oil-soluble pigment contained in the seed coat that is used as a natural dye and food coloring. In this study, we assembled and characterized the complete chloroplast genome of B. orellana as a resource for future genetic studies. With a total length of 159,825 bp, the chloroplast genome comprised of a large single-copy (LSC) region of 89,476 bp, a small single-copy (SSC) region of 19,617 bp, and two inverted repeat (IR) regions of 25,356 bp each. A total of 127 genes were predicted, consisting of 83 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. Phylogenetic analysis confirmed the position of B. orellana within the order Malvales.

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.
