The complete chloroplast genome of Fagus crenata (subgenus Fagus) and comparison with F. engleriana (subgenus Engleriana).

ABSTRACT: This study reports the whole chloroplast genome of Fagus crenata (subgenus Fagus), a foundation tree species of Japanese temperate forests. The genome has a total of 158,227 bp containing 111 genes, including 76 protein-coding genes, 31 tRNA genes and 4 ribosomal RNA genes. Comparison with the only other published Fagus chloroplast genome, F. engeleriana (subgenus Engleriana) shows that the genomes are relatively conserved with no inversions or rearrangements observed while the proportion of nucleotide sites differing between the two species was equal to 0.0018. The six most variable regions were, in increasing order of variability, psbK-psbI, trnG-psbfM, rpl32, trnV, ndhI-ndh and ndhD-psaC. These highly variable chloroplast regions in addition to 160 chloroplast microsatellites identified (of which 46 were variable between the two species) will provide useful genetic resources for studies of the inter- and intra-specific genetic structure and diversity of this important northern hemisphere tree genus.

The complete chloroplast genome of Castanea crenata Sieb. & Zucc.

Project description:The complete chloroplast genome sequence of Castanea crenata was sequenced and assembled using PacBio Sequel data. The cpDNA was 160,787?bp in length, containing a pair of inverted repeats (IRs) of 25,654?bp each separated by a large and small single copy (LSC and SSC) regions of 90,645?bp and 18,836?bp, respectively. The cpDNA contained 102 genes, including 65 protein-coding genes, 8 ribosomal RNA genes and 37 transfer RNA genes. Phylogenetic analysis indicated that C. crenata was closest to C. pumila var. pumila, which is known as a typical variety of American chinquapin or dwarf chestnut.

Complete chloroplast genome sequence of Procris crenata C.B.Rob (Urticaceae).

Project description:The complete chloroplast (cp) genome of Procris crenata C.B.Rob was reported. The cp genome was 154,124 bp in length and contained two inverted repeats (IRs) of 25,626 bp, which were separated by large single-copy and small single-copy of 84,599 bp and 18,273 bp, respectively. The GC content was 36.5%. A total of 113 functional genes were encoded, comprising 79 protein-coding genes, 30 tRNA genes, and four rRNA genes. This is the first reported plastid genome in Procris (Urticaceae), which will be useful data for resolving the relationship within the family.

The complete chloroplast genome of Rhamnus crenata Siebold & Zuccarini (Rhamnaceae).

Project description:Rhamnus crenata Siebold & Zuccarini is deciduous shrub or small tree plant that widely distributed in temperate and tropical regions of East to Southeast Asia. It has a chloroplast genome structure similar to that of other species of Rhamnus. It is 160,454 bp in size, including a large single-copy (LSC) region of 88,884 bp, a small single-copy (SSC) region of 18,734 bp and a pair of inverted repeats (IRs) of 26,418 bp. A total of 122 genes were annotated, including 80 protein-coding genes, 38 transfer RNA (tRNA) genes, and 4 rRNA genes. The overall GC content is 30.71%. Phylogenetic analysis shows that R. crenata is clustered with R. taquetii and R. globosa.

Characterization of the complete chloroplast genome of Ilex crenata Thunb. (Aquifoliaceae).

Project description:Ilex crenata Thunb. is a species of Aquifoliaceae with high ornamental and ecological values. In this study, the complete chloroplast (cp) genome of I. crenata was assembled and characterized through Illumina sequencing data. The entire cp genome of I. crenata was 157,988 bp in length with 37.64% overall GC content, containing a large single-copy (LSC) region of 87,414 bp and a small single-copy (SSC) region of 18,422 bp, which were separated by a pair of 26,076 bp inverted repeat (IR) regions. A total of 135 genes were annotated, including 88 protein-coding genes, 39 tRNA genes, and 8 rRNA genes. Phylogenetic analysis based on 78 conserved protein-coding genes demonstrated that I. crenata is closely related to I. viridis and I. szechwanensis.

Complete Chloroplast Genome Sequence of Fagus longipetiolata Seemen (Fagaceae): Genome Structure, Adaptive Evolution, and Phylogenetic Relationships.

Project description:Fagus longipetiolata Seemen is a deciduous tree of the Fagus genus in Fagaceae, which is endemic to China. In this study, we successfully sequenced the cp genome of F. longipetiolata, compared the cp genomes of the Fagus genus, and reconstructed the phylogeny of Fagaceae. The results showed that the cp genome of F. longipetiolata was 158,350 bp, including a pair of inverted repeat (IRA and IRB) regions with a length of 25,894 bp each, a large single-copy (LSC) region of 87,671 bp, and a small single-copy (SSC) region of 18,891 bp. The genome encoded 131 unique genes, including 81 protein-coding genes, 37 transfer RNA genes (tRNAs), 8 ribosomal RNA genes (rRNAs), and 5 pseudogenes. In addition, 33 codons and 258 simple sequence repeats (SSRs) were identified. The cp genomes of Fagus were relatively conserved, especially the IR regions, which showed the best conservation, and no inversions or rearrangements were found. The five regions with the largest variations were the rps12, rpl32, ccsA, trnW-CCA, and rps3 genes, which spread over in LSC and SSC. The comparison of gene selection pressure indicated that purifying selection was the main selective pattern maintaining important biological functions in Fagus cp genomes. However, the ndhD, rpoA, and ndhF genes of F. longipetiolata were affected by positive selection. Phylogenetic analysis revealed that F. longipetiolata and F. engleriana formed a close relationship, which partially overlapped in their distribution in China. Our analysis of the cp genome of F. longipetiolata would provide important genetic information for further research into the classification, phylogeny and evolution of Fagus.
