Causes and consequences of plant diversification in the Greater Cape Floristic Region: an example of the neglected genus Pteronia (Asteraceae)

Name: Causes and consequences of plant diversification in the Greater Cape Floristic Region: an example of the neglected genus Pteronia (Asteraceae)
Researchers: Trávníček Pavel (researcher)
Project Type: B - national grants (GA ČR, GA AVČR)
Realization from: 2019
Realization to: 2021
Summary: The evolutionary radiations in global biodiversity hot-spots have been of great interest of evolutionary biologists for a long time. Nevertheless, processes triggering the proliferation of taxa in particular clades are still not sufficiently understood. The project aims at investigating the role of genome-wide processes (whole genome duplication, genome size evolution) and ecological speciation (potential shifts in environmental niche space) in the most species rich family in the Cape flora, Asteraceae. Using a combination of state-of-the-art methodological approaches (Hyb-Seq, cytogenomics, flow cytometry, niche modelling) we will build a robust phylogeny, assess variation in nuclear genome size and the processes behind, identify frequency of polyploids, and characterize ecological niches of one of the species-richest Asteraceae genus in the Cape, Pteronia. Cross-disciplinary data integration will provide a new level of understanding of the evolutionary drivers generating the biological diversity in one of the species-richest plant family in the Cape, as well as on Earth.
