PhD position: Sweet or sour - how the nectar microbiome shapes the pollinator community in brassicaceous plants
We are looking for a highly motivated PhD candidate in the field of insect-flower-microbe interactions who would like to unravel the effect of nectar microbes on flower visiting insects.
Pollination by insects is rewarded with floral nectar. However, as a nutrient-rich and well-protected environment, flower nectar also supports a diverse community of beneficial, commensal, and antagonistic microbes. These microorganisms influence the interaction between the plant and its pollinators, but also with nectar robbers and flower-feeding herbivores by altering the nutritional value and the chemical composition of the nectar. Despite the importance of pollination for seed production of many brassicaceous crops, little is known on the role of the nectar microbiome for plant fitness and seed set in these plants. Besides plant fitness, nectar microbes also impact pollinator health and thereby strongly influence the pollinator community beyond individual plant-pollinator interactions.
The central questions of this PhD project are (I) does the microbiome in the flower nectar influences plant-pollinator interactions and plant fitness, (II) can specific microbes be used to improve seed set in brassicaceous crops as well as pollinator health.
As a PhD candidate, you will contribute to fundamental research in the context of sustainable crop production. You will be embedded in a diverse group of international scientists and collaborate with colleagues from both in- and outside Wageningen University & Research.
Your duties and responsibilities include:
- Designing and executing experiments with flowering plants, microbes and mutualistic and antagonistic insect flower visitors in the greenhouse and in the field.
- Analyse complex data sets involving e.g. metabarcode sequencing
- Chemical analysis of flower nectar using HPLC and GC-MS techniques.
- Supervise MSc and BSc students
- Writing and presenting research at/in internationally renowned conferences/journals
You will work here
The research is embedded within the Laboratory of Entomology Lab of Entomology - WUR, which is led by Prof. Bregje Wertheim (Bregje Wertheim - Wageningen University & Research). You will be co-supervised by Dr. Alexander Haverkamp (Alexander Haverkamp - Wageningen University & Research) and Dr. Karen Kloth (Karen Kloth - Wageningen University & Research). Your project is part of the MiCRop Consortium programme on microbial imprinting of crop resilience to (a)biotic stresses (https://www.microp.org)). Within MiCRop, you will receive training and scientific exposure on plant-microbiome interactions and will regularly meet and collaborate with junior and senior scientists from six universities and institutes in the Netherlands.

PhD student herbivorous insect-plant-microbiome interactions
We are looking for talented PhD candidates in the field of insect-plant-microbiome interactions who want to unravel how beneficial microbes can reduce insect herbivory. This vacancy involves two positions: One PhD position on root fly-cabbage-microbiome interactions, and one PhD position on aphid-pepper-microbiome interactions.
Cabbage root flies and aphids are major agricultural pests that are still largely controlled with insecticides. Alternative, more sustainable methods to combat these pest are desperately needed. Plants harbour diverse and dynamic microbial communities in and around their roots and shoots. Some of these microbes help the plant in suppressing insect herbivory directly, by reducing insect fitness, or indirectly by inducing plant defense. Many facets of these insect-plant-microbiome interactions are still largely unknown. In this project, you will explore the role of microbes in the rhizo- and/or phyllospere in protecting plants against insects. You will study plant-soil feedback mechanisms, make microbial isolates and test inoculants for their effect on insect and plant performance. You will perform physiological and molecular studies to understand the underlying mechanisms of microbe-induced plant resistance. With this, you will unravel the role of beneficial microbes and the processes that are crucial for plants to maximize profitable functions from their microbiome when attacked by insects.
As a PhD candidate, you will contribute to fundamental research in the context of sustainable crop production. You will be embedded in a diverse group of international scientists and collaborate with colleagues from both in- and outside Wageningen University & Research. Your responsibilities and opportunities will encompass:
Your duties and responsibilities include:
- Designing and executing experiments with herbivorous insects, plants and microbes
- Analysing complex data involving e.g. metabarcoding, metagenomics, and metabolomics
- Isolating and culturing microbes and testing inoculants on insect and plant performance
- Supervising MSc and BSc students
- Writing and presenting research at/in internationally renowned conferences/journal.
