The complete chloroplast genome of Juniperus squamata (Cupressaceae), a shrubby conifer from Asian Mountains.

ABSTRACT: The complete chloroplast genome of Juniperus squamata, a shrubby conifer of ornamental value, is determined in this study. The complete chloroplast genome size is 127,792?bp in length. The genome contains 118 genes, including 82 protein-coding genes, 32 transfer RNA genes, and four ribosomal RNA genes (16S ribosomal RNA, 23S ribosomal RNA, 4.5S ribosomal RNA, and 5S ribosomal RNA). It does not contain inverted repeat (IR) sequence. The overall GC content of J. squamata cpDNA is 35.1%. The phylogenetic analysis suggests its close relationship with J. recurva and J. tibetica from Himalaya and the Qinghai-Tibet Plateau, respectively. The genome may contribute to evolutionary studies of conifers.

Project description:The species of the genus Juniperus L. play an important role in Kazakhstan forest ecosystems and one of them is Juniperus seravschanica Kom. which has been listed as a rare species in the Red Book of Kazakhstan. The distribution area of J. seravschanica extends from Central Asia (Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, and Turkmenistan) to northern and eastern Afghanistan, northern Pakistan, Kashmir, southeastern Iran, and Oman. J. seravschanica occurred in the southern part of Kazakhstan along with the ranges Karatau, Talas Alatau, Kyrgyz Alatau, Chu-Ili, Karzhantau, and Ugam. The distribution area of J. seravschanica is constantly decreasing due to intensive logging, forest fires, and excessive cattle grazing. The species has ecological importance in the stabilization of mountain slopes against erosion, for hydrobiological regulation, and as a significant medicinal herb. The species J. excelsa M. Bieb., J. polycarpos K.Koch (var. polycarpos and var. turcomanica R.P.Adams), and J. seravschanica are morphologically very similar with some difficulties in species identification. For a better understanding of the evolutionary relationship of these species in the Juniperus genus, it is important to obtain genetic information on the highly conserved chloroplast (cp) genome. Due to the conserved genomic structure, the cp genome nucleotide sequences are widely used in species distinguishing and reconstructing phylogenetic relationships. Unfortunately, there are no publicly available nucleotide sequences of cp genomes data for J. polycarpos (var. polycarpos and var. turcomanica), J. excelsa and J. seravschanica. We report the de novo assembly of the J. seravschanica chloroplast genome by applying next-generation sequencing technology based on Illumina NovaSeq 6000. The assembled cp genome of J. seravschanica is 127,609 bp in length and contained 118 genes, including 82 protein-coding genes, 32 transfer RNA genes, and 4 ribosomal RNA genes. In total 152 simple sequence repeats were identified in the chloroplast genome sequence of J. seravschanica. The Bioproject (PRJNA883033), Sequence Read Archive (SRR21673293), and GenBank (OL684343) data were deposited at National Center for Biotechnology Information.
