Mitochondrial DNA B Resour. 2022 Aug 17;7(8):1479-1480. doi: 10.1080/23802359.2022.2102445. eCollection 2022.

Abstract

Handroanthus chrysanthus is a deciduous broadleaved species with ecological and medicinal value. Here, the complete chloroplast genome of H. chrysanthus is characterized to investigate its phylogenetic position in Bignoniaceae. The chloroplast genome is 159,437 bp in size with GC content of 38.1%, including a large single copy region of 85,659 bp, a small single copy region of 12,824 bp and a pair of inverted repeats of 30,477 bp. It encodes 132 genes, including 87 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Based on current available chloroplast genome sequences, the phylogenetic analysis indicated that H. chrysanthus is closely related to Tabebuia nodosa.

Keywords: Bignoniaceae; Handroanthus chrysanthus; chloroplast genome; phylogenetic analysis.
