The Leibniz Institute for Horticultural Sciences (IGZ) conducts excellent basic research in plant sciences with applications in horticulture focusing on vegetables and the use of plant diversity. The IGZ is a member of the Leibniz Association and is based in Grossbeeren. For further information, please visit our website: www.igzev.de.
The following position is available at the institute subject to approval by the funding organization from January 1, 2027, limited until December 31, 2030, in the research group 'Plant-Microbe Systems' within the BMFTR project 'Phytoprotect: PentaCross – Cross-Crop Research on Pentastiridius-Pathogen-Host Interactions in the SBR/Stolbur Complex':
Scientist (f/m/div) in Plant-Insect-Pathogen Interactions and Resistance Research
Reference number: 15/2026/2
The salary will be based on qualification and research experience according to the wage agreement TV-L, up to pay scale 13, full-time.
The 'PentaCross' research project investigates the reed glasswing cicada Pentastiridius leporinus as a native but invasive species in sugar beet, potato, and vegetable cropping systems, as well as the pathogens it transmits: Candidatus Arsenophonus phytopathogenicus (SBR) and Candidatus Phytoplasma solani (Stolbur). The aim is to gain a better understanding of the vector's biology and the host plants' defence mechanisms, and to derive sustainable strategies for integrated pest management from this.
Tasks include
- planning, conducting, and evaluating greenhouse and laboratory experiments to characterize the interaction of P. leporinus with vegetable crops, such as carrots and beetroot
- establishment of insect cultures, as well as standardized rearing and synchronization of P. leporinus
- investigating the transmission of pathogens to various host plants
- assessment of plant phenotypes, disease symptoms, yield, and other physiological characteristics
- performing and supervising molecular biological analyses, in particular DNA extraction and qPCR for the quantification of pathogens
- processing and statistical analysis of extensive phenotypic and genotypic datasets as a basis for genome-wide association studies (GWAS) to identify and characterize resistance markers
- integration of phenotypic, molecular, proteomic, and metabolomic data to elucidate resistance mechanisms
- documentation, interpretation, and presentation of results, as well as writing of publications and scientific reports
- independent communication and collaboration with the scientific institutions involved in the project and other partners from research, breeding industry, and farmers, as well as supervising technical assistants
Your profile
- a completed PhD in agricultural sciences, plant sciences, phytopathology, entomology, or a comparable discipline
- sound knowledge of, or a keen interest in, plant-insect-pathogen interactions
- experience in planning and carrying out biological experiments involving plants and insects
- good knowledge of molecular biology methods, in particular DNA extraction and qPCR
- proven experience in the quantitative recording and statistical analysis of biological data, e.g., using R
- proven experience in publishing research findings
- experience with GWAS, genotyping, bioinformatics, proteomics, or metabolomics would be an advantage
- a self-motivated, independent, and responsible approach to work, as well as strong organizational skills
- willingness to work with insect cultures and plant populations, and to carry out long-term experimental series
- an enthusiasm for interdisciplinary collaboration and scientific communication
- very good written and spoken German and English
- willingness to undertake business travel; a class B driving licence (car) is therefore an advantage
We offer
- a diverse and exciting work environment involving experimental work in the greenhouse and laboratory, as well as the analysis and interpretation of complex biological datasets
- involvement in an interdisciplinary research project with national partners
- flexible and family-friendly working time models and the possibility of mobile working (up to 50% of working time)
- VBL Ost company pension scheme for public sector employees, as well as a collectively agreed annual bonus and 30 days' vacation per year
- subsidy for the company ticket for local public transport or for the Deutschlandticket
