The developmental basis of floral nectary diversity and evolution. [PDF]
Summary Nectar is a central bridge between angiosperms and animal mutualists. It is produced by specialized structures termed nectaries, which can be found on different plant organs. Consumption of floral nectar by pollinators and the subsequent transfer of pollen contribute to the reproductive success of both angiosperms and their pollinators.

Genome evolution in plants and the origins of innovation
Summary Plant evolution has been characterised by a series of major novelties in their vegetative and reproductive traits that have led to greater complexity. Underpinning this diversification has been the evolution of the genome. When viewed at the scale of the plant kingdom, plant genome evolution has been punctuated by conspicuous instances of gene ...
