Barbara Gravendeel

I am a botanist and fascinated by the emerging field of evolution and development in an ecological context (eco-evodevo). I investigate how molecular mechanisms shape the morphological diversity of plant organs, both over deep evolutionary time in ancient biomes, as well as in newly created environments, most notably cities. Together with my collaborators, I work on eco-evodevo of orchid flowers, fruits and peduncles, lantern flowers and dandelion pappus.

Keywords

Development, flowers, fruits, genomics, herbaria, orchids, plants, transcriptomics, urban evolution

Research
interest

Evolution and ecology are intimately related. Research over the last decades has shown that evolutionary changes are taking place much more rapidly than previously thought, and contribute to the ecological adaptation repertoire of species. Such adaptation mechanisms are of vital importance for species to survive in the anthropocene.

Human induced changes have become an important cause of plant evolution worldwide. More and more people live in cities nowadays and this has led to huge changes in environmental conditions and the spatial configuration of natural habitats in the landscape. Wild species are rapidly adapting to the urban biome. We investigate adaptations of urban plant species by studying museum specimens collected in areas that became increasingly urbanized over the past 200 years. We revisit these areas to recollect specimens and study traits differently selected for in urban versus non-urban environments with a suite of  micro-morphological and genetic tools.

Erycina pusilla
Cynorkis fastigiata and Epipactis helleborine

Current
topics

A selection of the topics I am working on currently.

En Tibi herbarium of tomato

Ancient tomato genomics

Past processes that shaped the current genetic diversity of the domesticated tomato are still largely unknown. Using Illumina HiSeq, we sequenced and compared full genomes from tomato accessions stored worldwide in genebanks and herbaria up to 182 years…

Vanilla pods analyzed in RAAK MKB project

Microbiome of Vanilla

DNA extracts of fermented fruits of species of Vanilla are currently being sequenced to obtain an impression of their microbiome, i.e. the diversity of fungi and bacteria living inside. The diversity of the microbiome is very different among vanille fruits…
