Article Synopsis
- - The Bromeliaceae family, particularly the genus Tillandsia, has undergone significant diversification due to key innovations like the shift from C to CAM photosynthesis, which helps adaptations to dry environments.
- - Researchers used phylogenomic techniques and RNA sequencing to explore how these photosynthetic changes are linked to other adaptations for surviving in xeric conditions, including genetic and metabolic shifts.
- - Findings indicate that the evolution of CAM involved the expansion of certain genes related to growth regulation and the reprogramming of stress response genes, providing insight into how these adaptive traits are repeatedly developed in this diverse plant group.
The effects of specific functional groups of pollinators in the diversification of angiosperms are still to be elucidated. We investigated whether the pollination shifts or the specific association with hummingbirds affected the diversification of a highly diverse angiosperm lineage in the Neotropics. We reconstructed a phylogeny of 583 species from the Gesneriaceae family and detected diversification shifts through time, inferred the timing and amount of transitions among pollinator functional groups, and tested the association between hummingbird pollination and speciation and extinction rates.

Here, we compared the evolutionary dynamics of traits associated with floral morphology and climatic preferences in a clade composed of the genera Codonanthopsis, Codonanthe and Nematanthus (Gesneriaceae). To test the mode and specific components that lead to phenotypic diversity in this group, we performed a Bayesian phylogenetic analysis of combined nuclear and plastid DNA sequences and modeled the evolution of quantitative traits related to flower shape and size and to climatic preferences.
