Characterization of the complete chloroplast genome of Ammopiptanthus mongolicus (Papilionoideae), a rare and Endangered plant to China

Abstract

Ammopiptanthus mongolicus is a rare and Endangered plant of Ammopiptanthus (Papilionoideae) in China. It grows mainly in the arid and semi-arid regions. The complete chloroplast (cp) genome was assembled by Illumina paired-end reads data. The circular cp genome is 153,997 bp in size, including a large single copy (LSC) region of 83,957 bp, a small single copy (SSC) region of 18,008 bp and a pair of inverted repeat (IRs) regions of 26,016 bp. Besides, 5 genes possess a single intron, while another three genes ycf3, rps12, and clp have a couple of introns. The GC content of the entire A. mongolicus cp genome, LSC, SSC, and IR regions are 36.9, 34.6, 30.5, and 42.8%, respectively. Based on the concatenated coding sequences of cp PCGs, the phylogenetic analysis showed that A. mongolicus and A. nanus are closely related to each other within the family Leguminosae.
