The complete chloroplast genome of Libocedrus chevalieri, a Critically Endangered species in New Caledonia.

ABSTRACT: Libocedrus chevalieri is a rare endemic conifer from New Caledonia, and it is evaluated as Critically Endangered in the IUCN Red List of Threatened Species. To take conservation actions more effectively, a survey of its genomic background and evolutionary status is of great significance. Illumina paired-end reads were used to character the chloroplast (cp) genome of L. chevalieri. The circular genome is 122,068 bp in length, containing 115 genes, in which include 83 protein-coding genes, four ribosomal RNA genes, and 28 transfer RNA genes. Nine genes (atpF, rpoC1, ndhB, ndhA, rpl2, petB, rpl16, petD, rps12) have one intron, whilst one gene (ycf3) has two introns. Inverted repeat (IR) sequence doesn't exist in the genome. The GC content of the cp genome is 34.1%. The phylogenetic analysis demonstrates that L. chevalieri has a close relationship with L. plumosa.

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

Project description:BackgroundPhoebe (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.ResultsWe 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.ConclusionThis study will facilitate our understanding of population genetics, phylogenetic relationship and plant evolution of Phoebe species.

Characterization and Comparative Analysis of the Complete Chloroplast Genome of the Critically Endangered Species Streptocarpus teitensis (Gesneriaceae).

Project description:Streptocarpus teitensis (Gesneriaceae) is an endemic species listed as critically endangered in the International Union for Conservation of Nature (IUCN) red list of threatened species. However, the sequence and genome information of this species remains to be limited. In this article, we present the complete chloroplast genome structure of Streptocarpus teitensis and its evolution inferred through comparative studies with other related species. S. teitensis displayed a chloroplast genome size of 153,207 bp, sheltering a pair of inverted repeats (IR) of 25,402 bp each split by small and large single-copy (SSC and LSC) regions of 18,300 and 84,103 bp, respectively. The chloroplast genome was observed to contain 116 unique genes, of which 80 are protein-coding, 32 are transfer RNAs, and four are ribosomal RNAs. In addition, a total of 196 SSR markers were detected in the chloroplast genome of Streptocarpus teitensis with mononucleotides (57.1%) being the majority, followed by trinucleotides (33.2%) and dinucleotides and tetranucleotides (both 4.1%), and pentanucleotides being the least (1.5%). Genome alignment indicated that this genome was comparable to other sequenced members of order Lamiales. The phylogenetic analysis suggested that Streptocarpus teitensis is closely related to Lysionotus pauciflorus and Dorcoceras hygrometricum.
