Complete chloroplast genome of Lonicera crassifolia Batalin (Caprifoliaceae) and its phylogenetic implications

Abstract

Lonicera crassifolia is a prostrate or creeping, evergreen Lonicera species endemic to southwest China. Here, we reported the complete chloroplast (cp) genome of L. crassifolia (GenBank accession number: OK393707). The cp genome was 154,731 bp long, with a large single-copy region (LSC) of 88,619 bp and a small single-copy region (SSC) of 18,642 bp separated by a pair of inverted repeats (IRs) of 23,735 bp. It encodes 130 genes, including 85 protein-coding genes, 37 tRNA genes, and 8 ribosomal RNA genes. We also reconstructed the phylogeny of Lonicera using the maximum-likelihood (ML) method, including our data and previously reported cp genomes of related taxa. The phylogenetic analysis showed that L. crassifolia is a sister to the remaining Nintooa clade with strong bootstrap support.
