Dr Anne Visscher is a Research Fellow in Seed and Stress Biology at the Royal Botanic Gardens, Kew, and will supervise this internship. She has more than 17 years of experience in plant and seed biology, with a particular focus on survival and growth in extreme environments on Earth and in space. Her research aims to identify plant species with exceptional stress tolerance and to uncover the seed and plant traits that underpin this resilience. She is also interested in global patterns of plant and seed traits, including those associated with stress tolerance.
Anne’s research approach is highly integrative: depending on the question, she applies physiological, molecular, biophysical, biochemical, and genomic techniques, working both independently and in collaboration with colleagues across disciplines. She has published 18 scientific manuscripts to date and has supervised multiple MSc and PhD students, as well as interns, volunteers, and visiting researchers.
The Trait Diversity and Function Department investigates the properties of plants and fungi and their potential applications for human health, well-being, and sustainable development. Our research examines how traits have evolved and how they function, revealing how species adapt to particular environments and how resilient they may be to future change. This knowledge supports the conservation of plants and fungi and helps identify species that can be used sustainably and equitably for the benefit of humankind.
The department comprises six teams: Biological Chemistry, Character Evolution, Seed and Stress Biology, Comparative Fungal Biology, Plant Health and Adaptation, and Crops and Global Change. This internship is hosted by the Seed and Stress Biology team, based at the Millennium Seed Bank at Wakehurst in West Sussex. The team focuses on key seed functional traits—such as germination, longevity, and stress responses—in wild plant species to inform the development of effective seed conservation and use strategies.
The NTU 2026 internship will take place in the Seed and Stress Biology team, part of the Trait Diversity and Function Department and based at the Millennium Seed Bank (MSB) at Wakehurst, West Sussex. The team’s research focuses on key seed functional traits—such as germination, longevity, and stress tolerance—in wild plant species, with the aim of informing effective seed conservation and use strategies.
This internship forms part of a three-year project funded by the Garfield Weston Foundation: “Unlocking tree seed functional trait diversity and stress resilience to enhance ex situ conservation for restoration and use.” The student will work with existing tree seed collections held at the MSB to identify species with exceptional tolerance to high temperatures during germination and early seedling development—traits with potential relevance for reforestation and ecological restoration (Alfaro et al., 2014).
The project will involve experiments using previously identified candidate species that have shown tolerance to 42.5 °C heat during imbibition and germination. Interns will monitor germination under high-temperature treatments (42.5 °C and/or 45 °C) alongside control conditions. The results will be combined with existing datasets and analysed to address two core research questions:
Do species tolerant to 42.5 °C during imbibition/germination also tolerate 45 °C? How common is this trait among the candidate species?
Is heat tolerance at 42.5 °C and/or 45 °C consistent across multiple seed collections of the same species from different geographic regions?
From June 15 to August 31, 2026 (adjustable at thediscretion of the organisation)
