Persistent organic and natural contaminants and likelihood of cutaneous malignant melanoma among girls.
We determined the complete mitochondrial genome (mitogenome) sequence of a Chilean freshwater crayfish, Parastacus nicoleti (Philippi, 1882). This is the first complete mitogenome sequence of a non-Australian crayfish belonging to the family Parastacidae. The complete mitogenome of P. nicoleti is 20,894 bp in length and contains 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), two ribosomal RNAs (rRNAs) and a putative control region (CR). In the phylogenetic analysis, freshwater crayfishes were clearly divided into two monophyly groups, Northern and Southern Hemisphere groups. The P. nicoleti exhibited a sister-group relationship with all other Australian parastacid crayfishes.Magnolia fordiana var. hainanensis (Dandy) Noot. (Magnoliaceae) is an endemic and ornamental tree distributed in Hainan, China. In this study, we report and characterize the complete plastid genome sequence of M. fordiana var. hainanensis in order to provide genomic resources helpful for promoting its conservation and garden utilization. The complete plastome is 160,157 bp in length and contains the typical quadripartite structure of angiosperm, including two Inverted Repeat (IRs) regions of 26,573 bp, a Large Single-Copy (LSC) region of 88,255 bp and a Small Single-Copy (SSC) region of 18,756 bp. The plastome contains 114 genes, consisting of 80 unique protein-coding genes, 30 unique tRNA gene and 4 unique rRNA genes. The overall A/T content in the plastome of M. fordiana var. hainanensis is 60.70%. The complete plastome sequence of M. fordiana var. hainanensis will provide a useful resource for the conservation and garden utilization of this species as well as for the phylogenetic studies of Magnoliaceae.The first complete chloroplast genome (cpDNA) sequence of Caryodaphnopsis tonkinensis was determined from Illumina HiSeq pair-end sequencing data in this study. The cpDNA is 149,016 bp in length, contains a large single copy region (LSC) of 91,915 bp and a small single copy region (SSC) of 17,703 bp, which were separated by a pair of inverted repeats (IR) regions of 19,699 bp. The genome contains 126 genes, including 81 protein-coding genes, eight ribosomal RNA genes, and 36 transfer RNA genes. The overall GC content of the whole genome is 39.0%, and the corresponding values of the LSC, SSC, and IR regions are 37.7%, 34.4%, and 44.4%, respectively. Further phylogenomic analysis showed that C. tonkinensis clustered in a clade in Lauraceae family.Linnaea borealis L. is a creeping shrub which grows about 5-10 cm high and is a rare clonal plant. Linnaea is a monotypic genus. Here, we release and detail the complete chloroplast genome sequences of L. borealis, whose size is 161,576 bp, containing a large single copy region (LSC) of 85,609 bp and a single copy region (SSC) of 46,694 bp which typically separates by a pair of inverted repeats (IRs) of 29,210 bp. The amount of the overall genes is 136, which includes 37 tRNA genes, eight rRNA genes, and 91 protein-coding genes. The content of the G/C in whole plastome is 61.74% while the G/C content of the LSC, SSC, and IR region are 36.58%, 38.86%, and 42.25%, respectively. The complete cp genome sequences of L. borealis will be a useful resource to the phylogenetics study in family Caprifoliaceae.The first complete chloroplast genome (cpDNA) sequence of Cinnamomum longipetiolatum was determined from Illumina HiSeq pair-end sequencing data in this study. The cpDNA is 158,603 bp in length, contains a large single copy region (LSC) of 89,386 bp and a small single copy region (SSC) of 18,181 bp, which were separated by a pair of inverted repeats (IR) regions of 25,511 bp. The genome contains 129 genes, including 84 protein-coding genes, eight ribosomal RNA genes, and 37 transfer RNA genes. The overall GC content of the whole genome is 39.0%, and the corresponding values of the LSC, SSC, and IR regions are 37.7%, 33.9%, and 43.0%, respectively. Further phylogenomic analysis showed that C. longipetiolatum clustered in a clade in genus Cinnamomum.The complete chloroplast genome sequence of Salix variegata, a native shrub willow species in the south of China, is reported. The plastome is 155,743 bp in length, with one large single copy region of 84,950 bp, one small single copy region of 16,219 bp, and two inverted repeat (IR) regions of 27,287 bp. DMH1 in vivo It contains 130 genes, including 83 protein-coding genes, eight ribosomal RNA, and 38 transfer RNA. Phylogenetic tree shows that this species is a sister to S. purpurea. The published plastome within Salix provides significant insight for elucidating the phylogenetic relationship of taxa within Salicaceae.Primula helodoxa Balf.f. is a species endemic to southeastern China distributed in Tengchong county of Yunnan Province. Here is the first time to report the complete chloroplast genome sequence of P. helodoxa. The complete chloroplast genome was 151,909 bp in length, containing a large single-copy (LSC) region of 83192 bp, a small single-copy (SSC) region of 17,797 bp, and a pair of inverted repeats (IRs) regions of 25,460 bp. There are 137 genes in total, 91 protein-coding genes, eight rRNA genes, and 38 transfer RNA genes. The phylogenetic tree showed relative relationship of P. helodoxa and P. chrysochlora.The phylogenetic relationship of Caenidae remains hotly debated within the Ephemeroptera. We sequenced the complete mitochondrial genome of Caenis sp. (Ephemeroptera Caenidae) to discuss the phylogenetic relationships among the Caenidae. The mitochondrial genome of Caenis sp. collected from Jian'ou, Fujian province, China is a circular molecule of 15,392 bp in length containing 37 genes (13 protein-coding genes, 22 tRNAs, and two rRNAs), which showed the typical insect mitochondrial gene arrangement. In BI and ML phylogenetic trees using 23 species from 13 families, the monophyly of the families Caenidae, Heptageniidae, Isonychiidae, and Vietnamellidae was strongly supported. The clade of Caenidae is a sister clade to the clade of Teloganodidae and Baetidae.Ilex latifolia (Aquifoliaceae), commonly known as 'kudingcha', is an evergreen tree widely distributed in southwest China. It is well known for its health function due to possess antioxidant, antidiabetic, antihypertensive, anti-inflammatory, and anti-ischemic activities. Here, we first report and characterize its complete chloroplast genome based on Illumina paired-end sequencing data. The complete plastid genome was 157,601 bp, which contained inverted repeats (IR) of 26,077 bp separated by a large single-copy (LSC) and a small single copy (SSC) of 87,020 bp and 18,427 bp, respectively. The cpDNA contains 143 genes, comprising 95 protein-coding genes, 40 tRNA genes, and eight rRNA genes. The overall GC content of the plastome is 37.6%. The phylogenetic analysis of 18 selected chloroplast genomes demonstrated that I. latifolia is closely related to the congeneric I. integra.
