The complete chloroplast genome sequence of Michelia floribunda.

ABSTRACT: The first complete chloroplast genome (cpDNA) sequence of Michelia floribunda was determined from Illumina HiSeq pair-end sequencing data in this study. The cpDNA is 160,049 bp in length, contains a large single-copy region (LSC) of 88,140 bp and a small single-copy region (SSC) of 18,773 bp, which were separated by a pair of inverted repeats (IR) regions of 26,568 bp. The genome contains 132 genes, including 87 protein-coding genes, 8 ribosomal RNA genes, and 37 transfer RNA genes. Further phylogenomic analysis showed that M. floribunda was closely related to Michelia yunnanensis in Michelieae tribe.

The complete chloroplast genome sequence of Michelia figo based on landscape design, and a comparative analysis with other Michelia species.

Project description:In the landscape planning and design, the ecological concept should occupy a dominant position, and the construction of an 'environmentally friendly, resource-saving' ecological new city is inseparable from the cultivation of forest tree species. Michelia figo, is an important landscape design tree species. Michelia figo, is also an important ecological role in boreal and temperate forests, serving as wildlife habitats and watersheds and is an important landscape ornamental tree species. The complete chloroplast genome sequence of M. figo was characterized from Illumina pair-end sequencing. The chloroplast genome of M. figo was 160,118 bp in length, containing a large single-copy region (LSC) of 88,116 bp, a small single-copy region (SSC) of 18,797 bp, and two inverted repeat (IR) regions of 26,603 bp. The overall GC content is 39.30%, while the corresponding values of the LSC, SSC, and IR regions are 34.5%, 30.6%, and 42.0%, respectively. The genome contains 129 complete genes, including 85 protein-coding genes (62 protein-coding gene species), 36 tRNA genes (29 tRNA species), and 8 rRNA genes (4 rRNA species). The neighbour-joining phylogenetic analysis showed that M. figo and Magnolia odora clustered together as sisters to other Michelia species.

Project description:Michelia macclurei (Dandy, 1928) is an evergreen broad-leaved tree species native to South China. This species has great ecological and economic importance. However, the genomic study of M. macclurei has lagged far behind. Here, we reported the complete chloroplast genome sequence of M. macclurei. The chloroplast genome size of M. macclurei was 160,139 bp, consisting of a pair of inverted repeat (IR) regions (26,575 bp), which was separated by a large single copy (LSC) region (88,167 bp) and a small single copy (SSC) region (18,822 bp). A total of 113 unique genes were annotated, including 79 protein-coding genes, 30 tRNA genes, and four rRNA genes. The overall GC content was 39.2%. Phylogenetic analysis based on 16 whole chloroplast genome sequences of Michelia species suggested that M. macclurei and M. maudiae are sister to each other, and jointly sister to M. chapensis.
