Assessing the phylogenetic relationship among varieties of Toona ciliata (Meliaceae) in sympatry with chloroplast genomes.

ABSTRACT: Toona ciliata is an endangered species due to over-cutting and low natural regeneration in China. Its genetic conservation is of an increasing concern. However, several varieties are recognized according to the leaf and flower traits, which complicates genetic conservation of T. ciliata. Here, we sequenced the whole chloroplast genome sequences of three samples for each of four varieties (T. ciliata var. ciliata, T. ciliata var. yunnanensis, T. ciliata var. pubescens, and T. ciliata var. henryi) in sympatry and assessed their phylogenetic relationship at a fine spatial scale. The four varieties had genome sizes ranged from 159,546 to 159,617 bp and had small variations in genome structure. Phylogenomic analysis indicated
