Comparative chloroplast genomics of Erigeron (Asteroideae, Asteraceae).

ABSTRACT: The genus Erigeron L. (Astereae, Asteroideae, Asteraceae), commonly known as fleabanes, comprises approximately 457 species with a near-cosmopolitan distribution. However, taxonomic discrepancies persist within the genus. In this study, the complete chloroplast (cp.) genomes of 16 Erigeron species were sequenced and/or de novo assembled and compared with those of nine previously reported species. The complete cp. genomes ranged from 152,108 to 153,430 base pairs (bp) in length, with a large single-copy region of 84,250-85,191 bp, inverted repeat regions (each IRa and IRb) of 24,688-25,054 bp, and a small single-copy region of 18,093-18,530 bp. Each genome contained 112 unique genes, including 79 protein-coding genes, 29 tRNA genes, and 4 rRNA genes. Comparative analyses revealed conserved
