The population chloroplast genomes of Populus reveal the phylogenetic relationship between three new taxa of sect. Leucoides and their parents.

ABSTRACT:

Background

Poplars are important woody plants, which are widely distributed in the forests from the subtropics to the north of the Northern Hemisphere. Poplars have high ecological and economic value. However, there are frequent interspecific and intraspecific hybrids in Populus, resulting in a large number of intermediate taxa, which makes the morphological identification of Populus very challenging. Plastid genome is an important tool to study the evolutionary relationship of plants. Therefore, comparison and phylogenetic analysis were carried out based on the population chloroplast genomes of 34 individuals from 7 taxa.

Results

In this study, seven newly assembled and annotated chloroplast genomes of Populus were reported. They all had typical quadripartite structures wit
