Abstract:
We report the complete chloroplast genome of Primula obconica, a popular house-plant all over the world. The complete chloroplast genome of P. obconica was sequenced using an Illumina Miseq platform. The circular genome is 153,694 bp in length and comprises a large single copy (LSC, 84,485 bp) region and a small single copy (SSC, 17,689 bp) region, which are separated by a pair of inverted repeats (IRa and IRb, 25,760 bp each). The overall GC content is 37.2%. The P. obconica chloroplast genome encodes 113 unique genes, including 79 protein-coding genes, 30 transfer RNA (tRNA) genes, and four ribosomal RNA (rRNA) genes. Phylogenetic analysis based on 18 chloroplast genomes indicates that P. obconica is closely related to the clade of Primula sect. Carolinella, sect. Corusoides and sect. Monocarpicae.

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.
