Completing the Plant Tree of Life
Discovering and disseminating the evolutionary history of all plant genera.
The tree of life is fundamental knowledge for the biological sciences.
Like an evolutionary roadmap, it is essential for the exploration, prediction and exploitation of the properties of life on Earth.
From the identification of species new to science to the discovery of novel biomolecules or crops, the potential of the tree of life is immense but is yet to be fully harnessed because many of the tree’s branches remain unknown.
Since 2015, Kew has been working to complete the flowering plant tree of life by gathering genomic data for at least one species of every known genus.
We have now passed the halfway mark.
Achievements to date include:
- A tree of life containing >7,500 of the 13,600 genera of flowering plants, based on the Angiosperms353 universal gene set.
- An open data portal, the Kew Tree of Life Explorer, launched in February 2021, through which our tree of life and all underpinning data are made publicly available in regular releases.
- Angiosperms353, an innovative, open access, genomic toolkit for tree of life research on any flowering plant.
- Numerous scientific publications, including special issues of American Journal of Botany and Applications in Plant Sciences.
- Open access data production and analysis protocols.
- Establishment of a network of >300 collaborating scientists worldwide, driving >30 subprojects under the PAFTOL umbrella.
- Numerous public engagement activities at Kew and online.
In a new phase commencing April 2022, we aim to build on our achievements to date to:
Complete the plant tree of life
We will complete the global evolutionary backbone for plants at the genus level by sequencing the remaining 5,500 genera of flowering plants, building on our collaborative network to achieve this. We expect to publish significant scientific results on the evolution and classification of flowering plants.
Dynamically disseminate of the tree of life online
Kew Tree of Life Explorer through annual data releases and new developments to enhance its functionality.
- A complete tree of life for all 13,600 genera of flowering plants
- New genomic data for 5,500 genera of flowering plants that have not yet been analysed, made rapidly and openly accessible to all
- A redeveloped version of the Kew Tree of Life Explorer with novel functionality that responds to user requirements and increases reach
- Annual public data releases via the Kew Tree of Life Explorer, comprising the latest new data and updated version of the plant tree of life
- Scientific publications reporting novel evolutionary and taxonomic research based on our data
- Opportunities for training the next generation of plant biologists via internships and MSc/PhDs
- New public engagement opportunities in the setting of the Agius Evolution Garden
