Adaptation Evolution and Phylogenetic Analyses of Species in Chinese Allium Section Pallasia and Related Species Based on Complete Chloroplast Genome Sequences.

ABSTRACT: The section Pallasia is one of the components of the genus Allium subgenus Allium (Amaryllidaceae), and species relationship in this section is still not resolved very well, which hinders further evolutionary and adaptive studies. Here, the complete chloroplast genomes of five sect. Pallasia species were reported, and a comparative analysis was performed with other three related Allium species. The genome size of the eight species ranged from 151,672 bp to 153,339 bp in length, GC content changed from 36.7% to 36.8%, and 130 genes (except Allium pallasii), 37 tRNA, and 8 rRNA were identified in each genome. By analyzing the IR/LSC and IR/SSC boundary, A. pallasii exhibited differences compared with other seven species. Phylogenetic analysis
