Abstract
The genus Acer is widespread throughout the northern temperate zone, and many species within the genus are of ecological and economical importance. Here we report the newly sequenced chloroplast genome of Acer pubipetiolatum var. pingpienense. This chloroplast genome has a total length of 156,730 bp, and contains a pair of inverted repeats (IRs, 26,743 bp), a large single-copy (LSC) region of 71,582 bp and a small single-copy (SSC) region of 18,092 bp. Phylogenetic analysis suggests that A. pubipetiolatum var. pingpienense is closely related to A. laevigatum, and both fall into Section Palmata. The complete A. pubipetiolatum var. pingpienense chloroplast genome will provide an important genetic resource for future research into the conservation and evolution of this genus. Our findings also suggest that further research is necessary to elucidate the phylogenetic relationships between plant species within this genus.
