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

Abstract

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.
