MITOGENOME ANNOUNCEMENTSCharacterization of the complete chloroplast genome of the Chinese endangered species Cymbidium iridioides D. Don.

ABSTRACT: Cymbidium iridioides D. Don 1852 is a Class I endangered species in China having important ornamental and breeding values. This study used Illumina high-throughput sequencing technology to sequence the complete chloroplast genome of C. iridioides. The genome features of C. iridioides and its phylogenetic relationships were determined. The complete chloroplast genome is 156,599 bp, containing a pair of 26,736 bp inverse duplication regions, a large 85,242 bp single-copy region, and a small 17,885 bp single-copy region. The entire genome contains 76 protein-coding genes, 37 tRNA genes, and 4 rRNA genes. A phylogenetic tree of 25 Orchidaceae species revealed that C. iridioides was grouped within Sect. Iridorchis and comprised a clade with Cymbidium tracyanum.

The complete chloroplast genome of Cymbidium serratum (Orchidaceae): a rare and Endangered species endemic to Southwest China.

Project description:Cymbidium serratum is a dominant species in the large orchid family with beautiful flowers, thick petals, and long flowering periods, and has a long history of cultivation in Southwest China. However, its wild resources have been threatened with extinction due to environmental degradation and artificial exploitation. In this study, the complete chloroplast genome of C. serratum was obtained through Illumina sequencing. The size of chloroplast genome of C. serratum is 149,998 bp, including large single-copy (LSC) and small single-copy (SSC) regions over 84,854 bp and 13,926 bp, respectively, and two inverted repeats (IRs) of 25,609 bp. The total GC content was 37.11%. The chloroplast genome contains 129 genes, including 83 protein-coding genes, 8 rRNA genes, and 38 tRNA genes. The maximum-likelihood phylogenetic tree indicated that C. serratum is a sister species with the clade composed of C. faberi and C. goeringii. The complete chloroplast genome of C. serratum will contribute to protecting this highly endangered species, and provide genetic information about genetic diversity and sustainable use.

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.
