UCC scientist contributes to major global report released today on the world’s plants and fungi, along with collaborators from 42 countries.

Report names thousands of plant and fungal species as new to science in 2019, including some that might be valuable as foods, drinks or medicines.

A University College Cork plant scientist has contributed to a new report that takes a deep dive into the state of the world’s plant and fungal kingdoms globally.
The new data, the result of a huge and unprecedented international collaboration bringing together 210 scientists from 42 countries, show how we are currently using plants and fungi, what useful properties we are missing, and what we risk losing.
UCC plant scientist Dr Eoin Lettice is one of the co-authors of the report, published today (September 30th, 2020), by the Royal Botanic Gardens, Kew.
Dr Lettice said the publication comes at a critical time for global biodiversity:
“We live in a time of unprecedented biodiversity loss. Our report sheds light on the extinction risk of plants and fungi globally, with 2 in 5 plants now at risk of being wiped out. Given the importance of plants to society – they give us medicines, food, beverages, clothes, energy, and more – it’s never been more important that we identify, record and protect species wherever we find them and that we do that quickly, before it’s too late”.
Plants and fungi are the building blocks of life on planet Earth. They have the potential to solve urgent problems that threaten human life, but these vital resources are being compromised by biodiversity loss. The report highlights the pressing need to explore the solutions that plants and fungi could provide, to address some of the pressures facing people and the planet. These pressures include the triple threats of climate change, biodiversity loss, and food security.
The challenges in sustainably using plants and fungi to supply food to an ever-increasing human population is highlighted in the report.
“Just 15 plants provide 90% of humanity’s food energy intake. Our report shows that there are at least 7,039 edible plant species known to science. These novel crops could hold the key to feeding a growing global population,” said Dr Lettice.
The report also highlights the importance of Crop Wild Relatives (CWR). These are plants that are related to cultivated crops and could be used to introduce important traits like disease resistance into commonly grown crops. Such efforts would employ a mixture of traditional plant breeding and novel biotechnological approaches like genetic modification and gene-editing.
“Commercial crops like potato, wheat, rice and so on have been bred to produce high yields and in that regard they have been successful”, said Dr Lettice.
“Unfortunately, they have not always been bred to possess traits like resistance to new pests and diseases or the capacity to thrive under changing climatic conditions. We need to look back at the ‘family tree’ of these crops to see if there are wild relatives with useful characteristics that can now make our modern crops more adaptable”.
On a positive note, the team at Kew announce today that 1,942 plant species and 1,886 fungal species were named as new to science in 2019. Among these exciting discoveries are species that might be valuable as foods, drinks or medicines. Highlights include:
Six new species of Allium, the plant group to which garlic, onions, leeks and chives belong have been discovered.

The underlying data behind today’s report is also published in a series of 12 scientific research papers made freely available in the leading journal Plants, People, Planet.
