Ericaceae: Systematics, Ecology and Evolution

Resolving difficult relationships in the Ericales using phylotranscriptomics.

Ericales is a highly diverse clade of flowering plants that contains an array of economically important species such as blueberry, Brazil nut, and kiwifruit. The clade is also notable for containing the charismatic American pitcher plants, and several of the world's most dominant clades of tropical trees. To date, the phylogenetic relationships within Ericales have remained difficult to resolve due to deep, rapid diversifications and insufficient taxon sampling. Using a phylotranscriptomic approach, we present novel methods of analyzing the role gene duplication and genomic conflict found at recalcitrant nodes. In addition, using recent advances in divergence time estimation we will provide the biogeographic context leading to several adaptations. Resolving relationships within the Ericales will shed light on the evolution of key characteristics such as mycorrhizal associations, latex production, and plant carnivory. Furthermore, this study provides insight into the value of phylotranscriptomic approaches for our understanding of the evolution of major plant orders.
