Collaborative project: Utilization of innovative fungal root endophytes in seed treatments to strengthen vegetable crops with the aim to increase plant tolerance against biotic and abiotic stress - subproject C (InnoEndophyt)

Project


Project code: 2818811C19
Contract period: 15.09.2021 - 14.11.2024
Budget: 76,525 Euro
Purpose of research: Applied research
Keywords: vegetable production, horticulture, crop production, biological plant protection, plant nutrition, resistance

Abiotic and biotic stress factors represent current and future challenges for a high-quality vegetable production. Due to expiring approvals and complete bans of plant protection products and pesticides their selection decreases and pathogen resistances to those few available products are increasing at an alarming rate. In terms of sustainable crop protection, plants need to be strengthened by alternative methods in order to increase plant resistance to these stress factors. Promising, recently discovered native root endophytes belonging the order Sebacinales are non-host-specific and have the potential to strengthen plants systemically. In this project, chlamydospores of these root endophytes shall directly be applied to seeds with a seed coating. The plant-strengthening effect will be tested on economically relevant vegetables and crops in extensive greenhouse trials as well as in the field. These vegetables include cucumbers and tomatoes as the two most important greenhouse plants, as well as cauliflower, napa cabbage, lettuce, spinach and sweetcorn as important field-grown vegetables. This project aims to develop a marketable innovative product of seed coatings containing systemically acting root endophytic fungi, which verifiably increases plants resistances to pathogens ("induced resistance") and abiotic stress factors.
