The complete chloroplast genomes of the evergreen tree species Cinnamomum camphora and Cinnamomum parthenoxylon (Laurales: Lauraceae)

Abstract

Complete chloroplast genomes were characterized for two economically important tree species, Cinnamomum camphora and Cinnamomum parthenoxylon. The chloroplast genomes are 152,721 bp (C. camphora) and 152,760 bp (C. parthenoxylon) long, respectively, and both comprise a pair of inverted repeat (IR) regions, separated by a large single-copy (LSC) region and a small single-copy (SSC) region. The same panel of 112 gene species were annotated for both species, including 78 protein-coding (PCG), 30 tRNA, and 4 rRNA gene species. Phylogenetic analysis suggests that the species delimitation and interrelationship of C. camphora and C. parthenoxylon may need further investigation.

“…On the other hand, sequences submitted as C. camphora and C. parthenoxylon were frequently found to share the same haplotype. This supports the statement of Wu & al. (2019) that "the species delimitation and interrelationship of C. camphora and C. parthenoxylon may need further investigation.…”

The re-sequencing of complete chloroplast genome of Cinnamomum camphora (Lauraceae) from Quanzhou, China

“…Compared with the three previously reported genomes of C. camphora (MH050970; MF156716; LC228240) (Chen et al 2017 ; Wu et al. 2017 , 2019 ), the differences of the genome size, LSC, SSC, IR regions, and GC content were within 169 bp, 99 bp, 239 bp, 229 bp, and 0.08%, respectively, and their protein-coding genes, tRNAs and rRNAs were almost the same, indicating that there was less difference among the four genomes of C. camphora . Therefore, we speculate that the chloroplast genome of C. camphora may be relatively conserved.…”

“…However, there are few studies of C. camphora on genomic at present. Recent studies (Chen et al 2017;Wu et al 2017Wu et al , 2019 have finished the complete chloroplast genomes sequencing of C. camphora (GenBank accession MH050970; GenBank accession MF156716; GenBank accession LC228240) from Xi'an, Nanjing and Taiwan, China. In order to compare the chloroplast differences among different provenances, in this study, we report the complete chloroplast genome of C. camphora from Quanzhou, China based on Illumina pair-end sequencing platform, which will establish important basis for the further studies on the phylogenetic analysis of Lauraceae.…”
