The complete chloroplast genome sequence of Platanus × hispanica from Sichuan province, China, a medicinal plant and phylogenetic analysis

Abstract

Platanus × hispanica is a tree species with high ornamental value, which complete chloroplast(cp) genome was sequenced, assembled and annotated. The chloroplast genome of P. hispanica was 161,717 bp in length, including a large single copy (LSC) region of 92,106, a small single copy (SSC) region of 19,449 bp, and two inverted repeat (IR) regions of 25,081 bp. The GC contents of LSC, SSC, IR, and whole genome are 36.2, 33.0, 43.4, and 38.0%, respectively. There are 131 genes annotated, including 86 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The phylogenetic analysis revealed that P. hispanica was most related to Platanus occidentalis as a sister group with 100% bootstrap support. The complete chloroplast genome sequences of P. hispanica will provide valuable genomic information to further illuminate phylogenetic classification of Platanus genus.
