    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

Abstract Cyst nematodes are obligate, biotrophic parasites of many important agricultural crops that have the fascinating ability to reprogram plant cells and form a unique feeding structure called syncytium. The syncytium functions as a metabolic sink from which feeding nematodes acquire their nutrients for several weeks. Establishment of a successful cyst nematode-plant interaction strongly depends on plant hormone homeostasis. We have recently discovered that strigolactones play distinct roles in the interaction of beet cyst nematode (Heterodera schachtii) with Arabidopsis. Strigolactone signalling mutant max2 negatively affects nematode attraction to the roots, whereas both max2 and the strigolactone biosynthesis mutant max4 enhance syncytium development. Moreover, the exogenous application of the synthetic strigolactone GR24 expands the zone above the root tip where H. schachtii invades the host. We want to dissect the role of strigolactone pathway in the overall susceptibility of Arabidopsis to H. schachtii. Furthermore, we aim at understanding the molecular mechanisms underlying the effect of strigolactone signalling and responses in nematode attraction, host invasion, and syncytium development.
