Comparative chloroplast genomes and phylogenetic analyses shed new insights on the phyloevolution of different ploidy in Camellia reticulata.

ABSTRACT:

Background

Camellia reticulata Lindl. (C. reticulata) is the tallest ornamental camellia globally, with wild populations comprising a polyploid complex of diploids (2×), tetraploids (4×), and hexaploids (6×). The type specimen of C. reticulata is a heteroploid hexaploid derived from 2 × ancestors, including C. pitardii, C. saluenensis, and 2 × C. reticulata. Currently, limited information exists regarding the evolutionary characteristics of the chloroplast genomes of C. reticulata at different ploidy levels, and the phylogenetic position of 2 × and 4 × C. reticulata remains unclear.

Results

This study sequenced, assembled, and annotated the chloroplast genomes of 2 × and 4 × C. reticulata, comparing them with those of 6 × C. reticulata and other closely related species. The
