Characteristic and phylogenetic analyses of chloroplast genome for Syringa komarowii C.K.Schneid. (Oleaceae) from Huoditang, China, an important horticultural plant.

ABSTRACT: The genus Syringa (Oleaceae) comprises some of the most important cultivated horticultural trees worldwide. Syringa komarowii, is one of these important horticultural plants. We sequenced the complete chloroplast (cp) genomes of S. komarowii (previously identified as var. reflexa) using Illumina Hiseq X Ten platform. The cp genome exhibits a typical quadripartite structure with 158,020 bp in length, which consists of two copies of inverted repeat (IR) regions (25,676 bp) separated by a large single copy (LSC) region (87,628 bp) and a small single copy (SSC) region (19,040 bp). The cp genome of S. komarowii encodes a total of 132 genes, including 88 protein-coding genes, 36 tRNA genes and 8 rRNA genes. A maximum likelihood (ML) phylogenetic analysis resolved that S. komarowii in a clade with S. wolfii and S. yunnanensis. The ML tree also showed Syringa appeared more closely related to Ligustrum than to the other genera in the Oleaceae.

The complete chloroplast genome of Zabelia dielsii (Graebn.) Rehd. (Caprifoliaceae), an important horticultural plant in China.

Project description:The genus Zabelia R. Br. has been an important horticultural plant in the family Caprifoliaceae. However, due to the lack of efficient molecular markers and conservation efforts in recent decades, accompanied with deforestation, the germplasm resources are under severe threat, yet the systematic position of Zabelia is not clearly understood. In the present study, we analyzed the complete chloroplast (cp) genome of Zabelia dielsii (Graebn.) Rehd., which represents the first reported case of Zabelia. It was 155,584?bp in length, comprising a pair of 23,434?bp inverted repeat regions (IRs) separated by a large single-copy (LSC) region (89,521?bp) and a small single-copy (SSC) region (19,062?bp). Phylogenetic analysis supported the monophyly of Caprifoliaceae and suggested that Z. dielsii was closely related to Kolkwitzia amabilis and Dipelta floribunda. This complete chloroplast genome will contribute to further studies on population genetics, phylogeny, and conservation biology in Zabelia.

Characteristic of the complete chloroplast genome of Symphoricarpos sinensis, an important ornamental plant endemic to China.

Project description:Symphoricarpos sinensis is an important ornamental plant in China. Due to the lack of efficient molecular markers, although recent studies supported that Symphoricarpos was phylogenetically closely related to Lonicera, Triosteum, Heptacodium, and Leycesteria, relationships among these taxa remained uncertain. To examine the phylogenetic position of Symphoricarpos within Caprifoliaceae, we characterized the complete chloroplast (cp) genome of S. sinensis. The results showed that S. sinensis shared a typical quadripartite structure as with most angiosperms. It was 155,738 bp in length, including two inverted repeat (IR) regions (24,010 bp), a small single-copy (SSC) region (18,942 bp) and a large single-copy (LSC) region (88,776 bp). Phylogenetic analysis demonstrated that Caprifoliaceae and Adoxaceae formed two distinct monophyletic clades, and S. sinensis was closely related to lonicera and Triosteum, albeit with low support. The whole cp genome of S. sinensis will be useful resources for future studies on phylogeny and conservation in Symphoricarpos.

Analysis of the chloroplast genome and phylogenetic evolution of three species of Syringa.

Project description:BackgroundBy the time our study was completed, the chloroplast genomes of Syringa oblata, S. pubescents subsp. Microphylla, and S. reticulate subsp. Amurensis had not been sequenced, and their genetic background was not clear.The research contentIn this study, the chloroplast genomes of Syringa oblata, S. pubescents subsp. Microphylla, S. reticulate subsp. Amurensis, and five other species of Syringa were sequenced for a comparative genomics analysis, inverted repeat (IR) boundary analysis, collinearity analysis, codon preference analysis and a nucleotide variability analysis. Differences in the complete chloroplast genomes of 30 species of Oleaceae were compared with that of S. oblata as the reference species, and Ginkgo biloba was used as the out group to construct the phylogenetic tree.ResultsThe results showed that the chloroplast genomes of S. oblata, S. pubescents subsp. Microphylla, and S. reticulate subsp. Amurensis were similar to those of other angiosperms and showed a typical four-segment structure, with full lengths of 155,569, 160,491, 155,419, and protein codes of 88, 95, and 87, respectively. Because the IR boundary of S. pubescents subsp. Microphylla was significantly expanded to the large single copy (LSC) region, resulting in complete replication of some genes in the IR region, the LSC region of S. pubescents subsp. Microphylla was significantly shorter than those of S. oblate and S. reticulate subsp. Amurensis. Similar to most higher plants, these three species have a preference for their codons ending with A/T.ConclusionsWe consider the genus Syringa to be a synphyletic group. The nucleotide variability and phylogenetic analyses showed that Syringa differentiated before Ligustrum and Ligustrum developed from Syringa. We propose removing the existing section division and directly dividing Syringa into five series.

Identification and phylogenetic analysis of the genus Syringa based on chloroplast genomic DNA barcoding.

Project description:DNA barcoding is a supplementary tool in plant systematics that is extensively used to resolve species-level controversies. This study assesses the significance of using two DNA barcoding loci (e.g., psbA-trnH and trnC-petN) in distinguishing 33 plant samples of the genus Syringa. Results showed that the average genetic distance K2P of psbA-trnH DNA marker was 0.0521, which is much higher than that of trnC-petN, which is 0.0171. A neighbor-joining phylogenetic tree based on psbA-trnH and trnC-petN indicated that the identification rate of psbA-trnH and trnC-petN alone were 75% and 62.5%, respectively. The barcode combination of psbA-trnH+trnC-petN could identify 33 samples of the genus Syringa accurately and effectively with an identification rate of 87.5%. The 33 Syringa samples were divided into four groups: Group I is series Syringa represented by Syringa oblata; Group II is series Villosae represented by Syringa villosa; Group III is series Pubescentes represented by Syringa meyeri; and Group IV is section Ligustrina represented by Syringa reticulata subsp. pekinensis. These research results provided strong evidence that the combinatorial barcode of psbA-trnH+trnC-petN had high-efficiency identification ability and application prospects in species of the genus Syringa.

The Complete Chloroplast Genome Sequences of the Medicinal Plant Forsythia suspensa (Oleaceae).

Project description:Forsythia suspensa is an important medicinal plant and traditionally applied for the treatment of inflammation, pyrexia, gonorrhea, diabetes, and so on. However, there is limited sequence and genomic information available for F. suspensa. Here, we produced the complete chloroplast genomes of F. suspensa using Illumina sequencing technology. F. suspensa is the first sequenced member within the genus Forsythia (Oleaceae). The gene order and organization of the chloroplast genome of F. suspensa are similar to other Oleaceae chloroplast genomes. The F. suspensa chloroplast genome is 156,404 bp in length, exhibits a conserved quadripartite structure with a large single-copy (LSC; 87,159 bp) region, and a small single-copy (SSC; 17,811 bp) region interspersed between inverted repeat (IRa/b; 25,717 bp) regions. A total of 114 unique genes were annotated, including 80 protein-coding genes, 30 tRNA, and four rRNA. The low GC content (37.8%) and codon usage bias for A- or T-ending codons may largely affect gene codon usage. Sequence analysis identified a total of 26 forward repeats, 23 palindrome repeats with lengths >30 bp (identity > 90%), and 54 simple sequence repeats (SSRs) with an average rate of 0.35 SSRs/kb. We predicted 52 RNA editing sites in the chloroplast of F. suspensa, all for C-to-U transitions. IR expansion or contraction and the divergent regions were analyzed among several species including the reported F. suspensa in this study. Phylogenetic analysis based on whole-plastome revealed that F. suspensa, as a member of the Oleaceae family, diverged relatively early from Lamiales. This study will contribute to strengthening medicinal resource conservation, molecular phylogenetic, and genetic engineering research investigations of this species.
