The influence of leafontogenesis of pear(Pyrus communis) on the infection ability of Erwinia amylovora: a study of defense-related mechanisms. (R-1475)

This project aims to create a first step to gaining insight into the relationship between the leaf age of the peer with the matching composition of anti-oxidative enzymes, phenols and flavonoids in the leaves. Then we want to examine whether these enzymes and secondary metabolites are involved in building a defense mechanism in the leaves against the bacterium E. amylovora and whether the imposition of abiotic stress leads to increased resistance to fire blight.In this way a foundation can be layed te develop a strategy that allows to reduce parcel loss due to E. amylovora to a minimum and take the refinement into account. The project should allow more insight into the proportion of the maturity of the leaf of the host on the level of antioxidants and secondary metabolites and whether these products increase the defense mechanism against fire blight. Second, they examine the manner in which the administration of abiotic stress will manifest itself against the biotic pathogen E. amylovora, with the aim to integrate both the knowledge in the research practices of the UHasselt and on the other hand the producer through cultivation measures, who wants to garante a lower infection rates by E.amylovora.
