The complete chloroplast genome of Acer pentaphyllum (Sapindaceae), a critically endangered maple endemic to China

Abstract

Acer pentaphyllum is a critically endangered maple confined to the valley of Yalong River in Southwest China. The whole chloroplast genome of A. pentaphyllum was 156,862 bp in length with a typical quadripartite structure, containing a large single-copy (LSC) region of 85,292 bp, a small single-copy (SSC) region of 18,146 bp, and a pair of inverted repeat (IR) regions of 26,712 bp separated among them. Totally 137 unique genes were predicted, comprising 89 protein-coding genes, 39 tRNA genes, and 8 rRNA genes (4 rRNA types). The phylogenetic analysis showed that A. pentaphyllum was resolved as sister to the clade containing A. griseum and A. sino-oblongum. This study reported the first complete chloroplast genome sequences of A. pentaphyllum and reconstructed a phylogeny tree based on 16 Sapindaceae species, which may provide new insight into phylogenetic studies of Sapindaceae and further conservation strategies for A. pentaphyllum.

Comparative genomics and phylogenetic relationships of two endemic and endangered species (Handeliodendron bodinieri and Eurycorymbus cavaleriei) of two monotypic genera within Sapindales

“…There are some cp genomes in Sapindaceae s.l. species have been reported and deposited in Gen-Bank database, like Acer [34], Dodonaea [35], Aesculus [36][37][38][39], Dimocarpus [40], most of which were the genus Acer [41][42][43][44][45][46]. We also noticed that previous studies have revealed the complete cp genomes of H. bodinieri and E. cavaleriei [47][48][49], but focus mainly on the size and gene contents of the cp genome, lacking detailed comparative genomic and comprehensive phylogenetic analysis.…”
