Allmän beskrivning
This project has received funding from Maiju and Yrjö Rikala Horticultural Foundation (Maiju ja Yrjö Rikalan Puutarhasäätiö).
Globally plant diseases account for an annual yield loss of 14.1 %, or a cost of $200 billion. The Brassicaceae, from which many economically important crops are derived (oil seed rape, mustard, cabbage, kale), are subject to numerous pests, requiring investigation to improve the resistance of plants in this agriculturally important family. Glucosinolates (GSLs) play a central role in the defence strategy of Brassicaceae contributing to resistance against herbivores and insects. Moreover, they are responsible for the pungent or bitter taste of many species in this family and affect the nutritional value of the Brassicaceae crops. Some GSLs derivatives also have antibiotic effects, interesting for pathogens resistance. The amount and composition of glucosinolates differs between kale varieties resulting in differences in the pathogen resistance of kales.
This project aims to shed light on the protective mechanisms of different cultivated, landrace and wild kale varieties, against grey mould and downy mildew. Special emphasis will be paid on glucosinolates and their associations with resistance and susceptibility phenotypes of the studied varieties. Because Brassicaceae family has many economically important species, results of the research can be utilized in the future breeding plans of nutritious and resilient Brassica crops This approach could also provide novel, toxic free alternatives to plant protection, by enhancing the defensive mechanisms that are naturally present in the plants without effecting the flavour profile or the nutritional value of crops.
