Research project Multi functional resistance

Resistant plant genotypes are important components of an integrated approach to combat pathogens and pests. Consequently, plant breeders aim to develop new crop varieties with higher resistance in order to increase the sustainability of agriculture. However, plant resistance can also affect nectar quality, and hence potentially impair or improve pollination, which in turn can affect the quality and shelf life of food crops. In addition, resistance-conferring substances may affect the taste and consumer acceptance of food crops. Holistic research into the multidimensional interactions involved will open up new, previously unexplored opportunities for Swedish plant breeders, growers, and consumers.

Thus we propose a novel, interdisciplinary research program to elucidate effects of increasing resistance to herbivores on crop plants' pollination, shelf life, pathogen susceptibility, and fruit quality. Woodland strawberry will be used as a model plant, and the results will be tested on garden strawberry.

This industry-anchored project is truly interdisciplinary, involving experts on plant chemistry, integrated plant protection, resistance biology, pollination, as well as food and meal science. Four young researchers and three senior professors are involved in the scientific work packages. A wide range of scientific methods will be used, including chemical analyses, bioassays in the laboratory and in the field, taste and aroma analyses, and advanced shelf life analyses. Stakeholders involved include important representatives for farmers, food industry, and agricultural advisors.

This project will produce all-new conceptual knowledge, leading to important scientific publications regarding the effects of plant resistance on multidimensional interactions. At the same time it will culminate in concrete, implementable suggestions on how to design plant resistance in order to improve pollination, shelf life, and taste, with obvious benefits
for sustainability and the financial value for farmers and food industry.
