Exploring PCR-based target enrichment applications for a 'critically placed tribe' in Compositae: Rapid radiations in South American Moquiniastrum (Gochnatieae).

Moquiniastrum (Gochnatieae) is a genus comprising 21 species belonging to a "critically placed tribe" near the base of the Compositae. Distributed throughout much of South America, this genus is characterized by diverse morphologies, habits, and a slightly disjunct distribution in Argentina, Bolivia, Brazil, Paraguay, Peru, Uruguay, and Venezuela. Recent molecular phylogenetic studies that have sampled heavily from this genus suggest that current molecular markers are insufficient to accurately reconstruct the evolutionary history of this genus. Utilizing 15 transcriptomes available through the 1KP project, we have designed and screened a suite of new markers for PCR-based target enrichment and anticipate these new markers are sufficient to reconstruct recent radiations that have occurred in the South American genus Moquiniastrum and perhaps more broadly in the Compositae. We outline our marker design strategy and validation success, as well as implications for marker development in this diverse family of angiosperms.
