Extremely low nucleotide diversity among thirty-six new chloroplast genome sequences from Aldama (Heliantheae, Asteraceae) and comparative chloroplast genomics analyses with closely related genera.

ABSTRACT: Aldama (Heliantheae, Asteraceae) is a diverse genus in the sunflower family. To date, nearly 200 Asteraceae chloroplast genomes have been sequenced, but the plastomes of Aldama remain undescribed. Plastomes in Asteraceae usually show little sequence divergence, consequently, our hypothesis is that species of Aldama will be overall conserved. In this study, we newly sequenced 36 plastomes of Aldama and of five species belonging to other Heliantheae genera selected as outgroups (i.e., Dimerostemma asperatum, Helianthus tuberosus, Iostephane heterophylla, Pappobolus lanatus var. lanatus, and Tithonia diversifolia). We analyzed the structure and gene content of the assembled plastomes and performed comparative analyses within Aldama and with oth
