The complete chloroplast genome and phylogenetic analysis of Syringa reticulata subsp. amurensis (Rupr.) P.S.Green & M.C.Chang from Qinghai Province, China.

ABSTRACT: Syringa reticulata subsp. amurensis (Rupr.) P. S. Green & M. C. Chang (Oleaceae) is a shrub or tree with high medicinal value as well as great ecological significance as an urban garden plant. To better understand the molecular genetics and evolutionary of S. reticulata subsp. amurensis, its complete chloroplast genome was sequenced and annotated. The assembled chloroplast genome is a circular 156,141 bp sequence, consisting of 87,108 bp large single copy (LSC) region and 17,239 bp small single copy (SSC) region, which were flanked by a pair of 25,897 bp inverted repeats (IRs). The GC content of the chloroplast genome is 36.14%. Moreover, a total of 132 functional genes were annotated, including 88 protein-coding, 36 tRNA, and eight rRNA genes. Phylogenetic analysis showed that S. reticulata subsp. amurensis was most closely related to S. reticulata subsp. Pekinensis and the genus Syringa is paraphyletic group. This study provides important information for further phylogenetic studies on S. reticulata subsp. amurensis and its allies.

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.

The Biodiversity of Grapevine Bacterial Endophytes of Vitis amurensis Rupr.

Project description:In this paper, the composition profiles of bacterial endophytes in wild-growing Amur grape Vitis amurensis Rupr. grown in the south of the Russian Far East were analyzed using both a cultivation-dependent (sowing bacteria) and a cultivation-independent (next generation sequencing, NGS) approach. Both methods revealed the prevalent endophytes in V. amurensis were represented by Gammaproteobacteria—40.3–75.8%, Alphaproteobacteria—8.6–18.7%, Actinobacteria—9.2–15.4%, and Bacilli—6.1–6.6%. NGS also showed a large proportion of Bacteroidia (12.2%) and a small proportion of other classes (less than 5.7%). In general, NGS revealed a greater variety of classes and genera in the endophytic bacterial community due to a high number of reads (574,207) in comparison with the number of colonies (933) obtained after the cultivation-dependent method. A comparative analysis performed in this study showed that both wild grape V. amurensis from Russia and domesticated cultivars of V. vinifera from Germany and California (USA) exhibit the same basic composition of endophytic bacteria, while the percentages of major taxa and minor taxa showed some differences depending on the plant organ, grape individuals, environmental conditions, and sampling time. Furthermore, the obtained data revealed that lower temperatures and increased precipitation favored the number and diversity of endophytic bacteria in the wild Amur grape. Thus, this study firstly described and analyzed the biodiversity of endophytic bacteria in wild grapevine V. amurensis.
