Summary: | Paulownia elongata (Paulowniaceae) is an ornamental tree native to Asia. In this study, the chloroplast (cp) genome of P. elongata was assembled using genome skimming sequencing, and the phylogeny of Lamiales was reconstructed based on whole cp genome data. The cp genome of P. elongata is 154,670 bp in length, comprising two copies of inverted region (IR, 25,783 bp), regions separated by the large single copy (LSC, 85,370 bp) and small single copy (SSC, 17,734 bp) regions. The cp genome encodes 114 unique genes, including 80 different protein-coding genes, 30 tRNA genes, and four rRNA genes, with 19 duplicated genes in the IR regions. Phylogenetic analysis indicates that P. elongata together with two other Paulownia species form a clade, which is sister to Triaenophora shennongjiaensis.
