The complete chloroplast genome sequence of Distylium macrophyllum (Hamamelidaceae).

ABSTRACT: Distylium macrophyllum H.T.Chang is a critically endangered tree species endemic to southern China. In this study, we assembled and characterized the plastome of D. macrophyllum using Illumina paired-end data. The circular genome is 159,089 bp in size, consisting of two copies of inverted repeat (IR) regions of 26,235 bp, one large single-copy (LSC) region of 87,822 bp, and one small single-copy (SSC) region of 18,797 bp. It encodes a total of 114 unique genes, including 80 protein-coding genes, 30 tRNA genes, and four rRNA genes. Phylogenetic analysis based on 13 cp genome sequences indicated that D. macrophyllum was sister to the clade of D. tsiangii and Parrotia subaequalis.

Chloroplast phylogenomic insights into the evolution of Distylium (Hamamelidaceae).

Project description:BackgroundMost Distylium species are endangered. Distylium species mostly display homoplasy in their flowers and fruits, and are classified primarily based on leaf morphology. However, leaf size, shape, and serration vary tremendously making it difficult to use those characters to identify most species and a significant challenge to address the taxonomy of Distylium. To infer robust relationships and develop variable markers to identify Distylium species, we sequenced most of the Distylium species chloroplast genomes.ResultsThe Distylium chloroplast genome size was 159,041-159,127 bp and encoded 80 protein-coding, 30 transfer RNAs, and 4 ribosomal RNA genes. There was a conserved gene order and a typical quadripartite structure. Phylogenomic analysis based on whole chloroplast genome sequences yielded a highly resolved phylogenetic tree and formed a monophyletic group containing four Distylium clades. A dating analysis suggested that Distylium originated in the Oligocene (34.39 Ma) and diversified within approximately 1 Ma. The evidence shows that Distylium is a rapidly radiating group. Four highly variable markers, matK-trnK, ndhC-trnV, ycf1, and trnT-trnL, and 74 polymorphic simple sequence repeats were discovered in the Distylium plastomes.ConclusionsThe plastome sequences had sufficient polymorphic information to resolve phylogenetic relationships and identify Distylium species accurately.

The genome annotation displayed a total of 135 genes, including 82 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. Phylogenetic analysis with 7 Liliaceae species revealed that N. macrophyllum was the basal species of tribe Lilieae and was close to Cardiocrinum giganteum.

Novel microsatellite markers for Distylium lepidotum (Hamamelidaceae) endemic to the Ogasawara Islands.

Project description:BackgroundDistylium lepidotum is a small tree endemic to the Ogasawara Islands located in the northwestern Pacific Ocean. This species is a sole food for an endemic locust, Boninoxya anijimensis. Here, we developed microsatellite markers to investigate genetic diversity and genetic structure and to avoid a genetic disturbance after transplantation to restore the Ogasawara Islands ecosystem.ResultsMicrosatellite markers with perfect dinucleotide repeats were developed using the next-generation sequencing Illumina MiSeq Desktop Sequencer. Thirty-two primer pairs were characterized in two D. lepidotum populations on Chichijima and Hahajima Islands of the Ogasawara Islands. The number of alleles for the markers ranged from three to 23 per locus in the two populations. Expected heterozygosity per locus in each population ranged from 0.156 to 0.940 and 0.368 to 0.845, respectively.ConclusionsThese microsatellite markers will be useful for future population genetics studies of D. lepidotum and provide a basis for conservation management of the Ogasawara Islands.
