How plants sense and respond to their neighbors: variation on a theme

Plants rely on light not just for photosynthesis but also for information.  Many plants have a sophisticated suite of photoreceptors and responses that allow them to sense and respond to competition for light from their neighbors. Known as the shade avoidance response, the response to neighbor shade can include increased stem elongation, altered branching, and early flowering. Plants undergoing shade avoidance prioritize growth over defense and reduce allocation to fruit and seed, reducing agronomic yield.

Biogeography, biome shifting, and functional traits in a widespread plant clade

In connection with our development of Viburnum (Adoxaceae) as a model lineage for studies of plant evolution and ecology, we have inferred a comprehensive dated phylogeny based on multiple lines of evidence.  Jointly with our phylogenetic inference, we have estimated past geographic movements and shifts between mesic forest biomes.  This provides us with reliable estimates for movements within and between continents throughout the Cenozoic, as well as for multiple instances of adaptation to colder climates.  Much of the action took place in Asia, with&nbsp
