Characterization of the complete chloroplast genome of the endangered Chinese species Cymbidium lowianum (Rchb.f.) Rchb.f.

ABSTRACT: Cymbidium lowianum (Rchb.f.) Rchb.f. is a Class I endangered species in China with important ornamental, economic, and breeding value, especially wild C. lowianum. This study used Illumina high-throughput sequencing technologies to sequence and analyze the complete chloroplast genome of C. lowianum. The genome features of C. lowianum and the phylogenetic relationships among Orchidaceae species were reported and established. The complete chloroplast genome is 155,447 bp long, consisting of a pair of inverse duplication regions that are 26,710 bp long, a large single-copy region of 84,184 bp, and a small single-copy region of 17,843 bp. The entire genome contains 74 mRNA genes, 30 tRNA genes, and 4 rRNA genes. The phylogenetic tree of 24 Orchidaceae species revealed Cymbidium lowianum is more closely related to Cymbidium erythraeum.

Complete chloroplast genome sequences of two endangered Phoebe (Lauraceae) species.

Project description:BACKGROUND:Phoebe (Lauraceae) comprises of evergreen trees or shrubs with approximately 100 species, distributed in tropical and subtropical Asia and Neotropical America. A total of 34 species and three varieties occur in China. Despite of economic and ecological value, only limited genomic resources are available for this genus. RESULTS:We sequenced the two complete chloroplast (cp) genomes of Phoebe chekiangensis and P. bournei using Illumina sequencing technology via a combined strategy of de novo and reference-guided assembly. We also performed comparative analyses with the cp genomes of P. sheareri and P. sheareri var. oineiensis previously reported. The chloroplast genomes of P. chekiangensis and P. bournei identically contain 112 genes consisting of 78 protein coding genes, 30 tRNA genes, and 4 rRNA genes, with the size of 152,849 and 152,853 bp, respectively. From the two chloroplast genomes, 131 SSRs were identified and 12 different SSRs located in five protein coding genes. The analysis showed the extremely conserved structure of chloroplast genomes with surprisingly little variations at the LSC/IR and SSC/IR boundaries. Moreover, the mean nucleotide diversity was found to be 0.162% for 77 regions, suggesting an extraordinarily low level of sequence divergence. Four highest divergent regions (trnH-psbA, rps14-trnT, petA-psbJ, ccsA-ndhD) with the percentage of nucleotide diversity higher than 0.50% were identified, which had potential use for species identification and phylogenetic studies. CONCLUSION:This study will facilitate our understanding of population genetics, phylogenetic relationship and plant evolution of Phoebe species.
