Abstract

Characterization of the complete Chloroplast genome of Correa carmen, a valuable winter-flowering shrub

Correa carmen is considered important because of its considerable ornamental and economic value. The most striking characteristic of C. carmen flowers is their long winter-flowering period. In the present study, we generated the first complete C. carmen chloroplast genome sequence based on Illumina paired-end sequencing data. The entire chloroplast genome comprises a circular molecule with 156,759 bp that forms a quadripartite organization with two inverted repeats (26,981 bp) separated by large (84,887 bp) and small (17,910 bp) single copy sequences. The C. carmen genome includes 95 protein-coding genes, 31 transfer RNA genes, and eight ribosomal RNA genes. Additionally, the base composition of the genome is biased (30.38% A, 18.92% C, 19.63% G, and 31.07% T) with an overall GC content of 38.55%. The results of a phylogenetic analysis are consistent with the traditional taxonomic framework of the family Rutaceae, and C. carmen is closely related to Phellodendron amurense.
