Complete plastome sequence of Osmanthus armatus and phylogenetic implications in Oleaceae.

ABSTRACT: Osmanthus armatus (Oleaceae) is mainly distributed in the southwest of China and also planted in arboretums as an ornamental plant. In the present study, the plastome of O. armatus was reconstructed using genome skimming sequencing, and the phylogeny analysis was inferred based on whole plastome data. The plastome of O. armatus is 155,259?bp in length, comprising two copies of inverted regions (IR, 25,680?bp) separated by the large single copy (LSC, 86,534?bp) and small single copy (SSC, 17,365?bp) regions. The genome encodes 114 unique genes, including 80 different protein-coding genes, 30 tRNA genes, and four rRNA genes, with 20 duplicated genes in the IR regions. Phylogenetic analysis suggests that the representative species from Osmanthus is monophyletic, and O. armatus is sister to O. fragrans within this genus.

The complete mitochondrial genome of Osmanthus fragrans (Lamiales, Oleaceae) from China.

Project description:Osmanthus fragrans is a well-known ornamental tree with high medicinal and edible values. In this study, the complete mitochondrial genome sequence of O. fragrans was assembled, annotated, and analyzed using phylogenomic methods. The complete mitochondrial genome of O. fragrans was 563,202 bp in length and displays an overall GC content of 44.58%. Sixteen chloroplast-derived segments with an average length of 1260 bp were identified. The complete mitochondrial genome contained 74 genes in total, including 44 protein-coding, three rRNA, and 27 tRNA genes, among which seven protein-coding and six tRNA genes were chloroplast-derived. Phylogenetic analysis showed that O. fragrans was closely related to Chionanthus rupicola within the Oleaceae. This study could provide genomic resources for a better understanding of O. fragrans and further studies on the evolution of Oleaceae.

The complete chloroplast genome sequence of Chrysojasminum subhumile and its phylogenetic position within Oleaceae.

Project description:We assembled and characterized the complete chloroplast genome sequence of Chrysojasminum subhumile (W.W.Sm.) Banfi & Galasso 2014, a valuable horticultural and medicinal plant species. The total genome size was 159,918 bp in length and the GC content was 37.4%. It displayed a circular structure and could be divided into a large single-copy region, a small single-copy region, and a pair of inverted repeat regions. The genome encoded a total of 131 unique genes, including 82 protein-coding genes, 41 tRNA genes, and eight rRNA genes. Among these genes, 17 contained a single intron, and two genes had two introns. Phylogenetic analysis results showed that C. subhumile was closely related to Jasminum.

The complete plastome sequence of Tanakaea radicans (Saxifragaceae) and its phylogenetic analysis.

Project description:Tanakaea radicans is classified in the monotypic genus Tanakaea in the Saxifragaceae. It is a small, evergreen plant with a disjunct distribution in Japan and China. Here, we report and characterize for the first time the complete plastid genome sequence of T. radicans. The chloroplast genome is 155,265 bp in length and contains a pair of inverted repeats (25,794 bp) separated by a large single copy (86,289 bp) and a small single copy (17,388 bp). A total of 113 unique genes, including 79 protein-coding, 30 tRNA, and four rRNA genes, were annotated. Phylogenetic analysis showed that T. radicans was sister to Leptarrhena pyrolifolia within Huecheroids linage of Saxifragaceae.

Genetic diversity of androdioecious Osmanthus fragrans (Oleaceae) cultivars using microsatellite markers.

Project description:For cultivar classification, identification, and genetic improvement, microsatellite markers were developed to analyze the genetic diversity of androdioecious Osmanthus fragrans cultivars. • Fifteen microsatellite markers were developed from sequences downloaded from the National Center for Biotechnology Information, which included two with null alleles. These primers were screened on 62 typical androdioecious O. fragrans cultivars belonging to four groups (Asiaticus, Albus, Luteus, and Aurantiacus). The number of alleles ranged from two to six, with a mean of 3.7 per locus. The observed and expected heterozygosities ranged from 0.1000 to 0.9091 and from 0.1287 to 0.9167, respectively. Results from structure analyses indicated that Asiaticus and Albus were genetically mixed, and Luteus and Aurantiacus were partially genetically differentiated. • These markers will be useful for genetic study of androdioecious O. fragrans cultivars and facilitate cultivar classification, particularly for the cultivar groups Luteus and Aurantiacus.

Phylogenetic placement of Ceratophyllum submersum based on a complete plastome sequence derived from nanopore long read sequencing data.

Project description:ObjectiveEutrophication poses a mounting concern in today's world. Ceratophyllum submersum L. is one of many plants capable of living in eutrophic conditions, therefore it could play a critical role in addressing the problem of eutrophication. This study aimed to take a first genomic look at C. submersum.ResultsSequencing of gDNA from C. submersum yielded enough reads to assemble a plastome. Subsequent annotation and phylogenetic analysis validated existing information regarding angiosperm relationships and the positioning of Ceratophylalles in a wider phylogenetic context.

The complete plastome of Saxifraga giraldiana Engler and its phylogenetic analysis.

Project description:Saxifraga giraldiana Engler is a common subalpine and alpine plant belonging to Saxifragaceae. However, the genetic diversity of this species has remained to be explored. In this study, we have assembled and characterized the complete chloroplast genome of S. giraldiana, filling this knowledge gap and uncovering its genetic composition. The chloroplast genome is 147,267 bp long and contains 131 genes, including 85 protein-coding genes, 38 tRNA genes, and eight rRNA genes. Furthermore, we have performed a phylogenetic analysis of 19 representative species within Saxifraga. As a result, we have found that S. giraldiana, together with S. implicans and S. stellariifolia, forms a monophyletic group. These findings have implications for the conservation and utilization of S. giraldiana.

Project description:Illigera grandiflora, a kind of traditional medicinal liana, belongs to the Illigera Blume of the Hernandiaceae. In this study, we reported the characteristics of complete plastome for I. grandiflora. Its total plastome was 156,138 bp in length, comprising a large single-copy region(LSC) of 84,931 bp, a small single-copy region (SSC) of 18,544 bp, and a pair of inverted repeat (IR) regions of 26,549 bp. The overall GC content was 39.16% (LSC, 37.77%; SSC, 33.89%; IR, 43.21%). The plastome encoded 134 genes, including 83 protein-coding genes, 42 transfer RNA genes, and 10 ribosomal RNA genes. The relationships in our phylogeny showed that the two Illigera species are located in the same clade, with Hernandia nymphaeifolia being the next sister group, followed by Wilkiea huegeliana.
