The complete chloroplast genome of a Chinese endemic ornamental plant Sorbus unguiculata Koehne (Rosaceae).

ABSTRACT: Sorbus unguiculata is a pinnate-leaved deciduous shrub growing in mixed forests in Sichuan province, China. It is one of the least known species in the genus with high ornamental value. In this study, we firstly assembled and annotated the complete chloroplast genome of the species using the next-generation sequencing method. The results showed that the chloroplast genome size is 159,900?bp, comprising of a large single-copy (LSC) region of 87,888?bp, a small single-copy (SSC) region of 19,256?bp, and a pair of IR regions of 26,378?bp. The whole cp genome predicted 109 genes in total, including 76 protein-coding genes, 29 tRNAs, and 4 tRNAs. The overall GC content of the chloroplast genome is 36.6%. The phylogenetic relationship exhibited that S. unguiculata is closely clustered with S. helenae in Sorbus.

The complete chloroplast genome sequence of Sorbus amabilis (Rosaceae).

Project description:Sorbus amabilis Cheng ex Yü, a small excellent ornamental tree species, is only distributed in Eastern China. In this study, we assembled and annotated the complete chloroplast (cp) genome of the species using the next-generation sequencing for the first time. The cp genome was 160,006 bp in size, consisting of two copies of invert repeat (IR) regions of 26,405 bp, one large single-copy (LSC) region of 87,870bp, and one small single-copy (SSC) region of 19,326 bp. The overall GC content of the genome was 36.55%. The genome was predicted to contain 128 genes, including 88 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis of 25 chloroplast genomes in Rosaceae indicated that S. amabilis is most closely related to S. commixta. These findings may provide useful information to the phylogeny of the genus Sorbus.

The complete chloroplast genome of Rubus rosifolius (Rosaceae), an ornamental and medicinal plant.

Project description:Rubus rosifolius belongs to the genus Rubus in the family Rosaceae and is widely distributed globally. It has white flowers and red fruits. Moreover, it has medicinal value for diseases of the stomach and other areas. However, the complete chloroplast (cp) genome of R. rosifolius remains unclear. In the present study, we sequenced the complete cp genome of R. rosifolius (GenBank accession no. OL435124), which had a typical quadripartite structure and a size of 155,650 bp. Fifteen genes (trnK-UUU, rps16, trnG-UCC, atpF, rpoC1, trnL-UAA, trnV-UAC, petB, petD, rpl16, rpl2, ndhB, trnI-GAU, trnA-UGC, and ndhA) contained an intron, and two genes (clpP and ycf3) contained two introns. The gene rps12 showed trans-splicing. Phylogenetic analysis showed that R. rosifolius was closely related to Rubus taiwanicola, Rubus rubroangustifolius, and Rubus glandulosopunctatus.

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.
