Davide Bulgarelli comes from Italy where he obtained a PhD in Plant Biology and Crop Production from the University of Milan, prior working as a post-doctoral researcher at the Max Planck Institute for Plant Breeding Research in Cologne (Germany). In 2013, Davide secured a prestigious Royal Society of Edinburgh personal research fellowship and established his own group at the University of Dundee where is currently a Senior Lecturer and Principal Investigator at the Division of Plant Sciences. Davide is also Public Engagement Champion for his Division, Programme Lead for the CSC scholarships within the School of Life Sciences and a member of the coordinating committee of the International Phytobiomes Alliance.
Plants thrive in association with remarkably rich and diverse microbial communities, collectively referred to as the plant microbiota. Similar to the microbiota inhabiting the digestive tract of vertebrates, the plant microbiota can promote the growth, development and health of their hosts. For example, the microbiota populating the rhizosphere, the interface between plant roots and soil, can facilitate mineral uptake from soil and enhance pathogen protection, effectively providing a more sustainable alternative to agrochemicals. Despite the sheer complexity of soil, microbes populating the root-soil interface are not stochastically assembled, rather the composition of these communities is the result of a selective process mediated, at least partially, by the plant itself [Figure 1]. My team is interested in deciphering the structure function and host control of the microbiota populating the root-soil interface, using crop plants as experimental models. To achieve this ambitious task, we use an innovative research framework encompassing seemingly unrelated disciplines including plant genetics, microbial ecology and computational biology. Our long-term ambition is gaining a precise understanding of plant genes shaping the microbiota and capitalise on this knowledge to develop innovative solutions to decouple crop production from non-renewable inputs in agriculture.
Figure 1: Plant cell material and organic compounds released by the roots influence the growth of certain microbes (coloured shapes) in the general soil microbiota. The plant’s genetics further fine tunes the microbial community that grows in the rhizosphere and roots. Modified from The Scientist (2018) 32:27.

I teach molecular plant-soil microbes interactions in the Level 3 course BS32008 (Plant Sciences) and the Level 4 course BS42005 (advanced Plant Sciences).
Animating Science Project
Animating Science uses stop motion animation to create animated films about Life Science concepts and processes. This film was produced by members of the public in collaboration with my group and animator Andrew Low as part of our annual Plant Power Day 2019 at the University of Dundee Botanic Garden. This project was funded by BBSRC.
Plant Microbiome to the Rescue is a short animation examining the interaction between soil microbes and plants in our very own plant microbiome. It shows the good, the bad and the ugly of the soil microbe world and how they can contribute to the health of many plants.
Article, How can understanding plants and microorganisms help feed the world?, aimed at school pupils about the research of Davide Bulgarelli and his career to date in plant sciences. Includes a worksheet for pupils to complete in class.
This article was produced by Futurum, a magazine and online platform aimed at inspiring young people to follow a career in the sciences, research and technology. For more information, teaching resources, and course and career guides, see www.futurumcareers.com
I am available for media commentary on my research.
