Abstract

Aganope is a genus in the family Fabaceae, with only 11 species. They are distributed throughout Asia and Africa. Aganope dinghuensis, a newly reported species, is native to China with a restricted distribution. We, therefore, report its complete chloroplast genome for better future conservation. The chloroplast genome of A. dinghuensis is 143,690 bp, with a GC content of 35.32%. In the genome, a pair of inverted repeat regions of 13,015 bp each, a large single-copy region of 98,824 bp, and a small single-copy region of 18,836 bp were identified. Genome annotation identified 115 genes, comprising 74 protein-coding genes, 8 ribosomal RNA genes, and 33 transfer RNA genes. Repeat analysis indicates that the chloroplast genome of A. dinghuensis contains 126 simple sequence repeats (SSR), of which the majority are A/T mononucleotides. Phylogenetic analysis revealed that A. dinghuensis is a sister to the clade that includes Indigofera tinctoria, Desmodium uncinatum, Sarcodum scandens, Wisteria brachybotrys, and Callerya nitida.
