PhD defence: What is the mechanism behind host-nematode interactions?
Mechanisms of plant-nematode interactions in natural soils are not well-known as the majority of our current findings are derived from in vitro bioassays.
Md Maniruzzaman Sikder studied the impact of several secondary metabolites such as, benzoxazinoids, glucosinolates, camalexin, flavonoids and phytohormones on soil nematode communities. He found that secondary metabolites modulate soil nematode communities with the most profound effects on endoparasitic nematodes having an intimate relationship with their hosts. Moreover, he also evaluated the effects of soil microbes on the infectivity of root knot-nematode and demonstrated an indirect modulating effect of flavonoids on nematode root invasion via the root-associated microbiome. This knowledge contributes to the understanding and exploitation of plant secondary metabolites, phytohormone and soil microbes for protection against harmful plant parasitic nematodes in ecofriendly and sustainable nematode management strategies.
The PhD study was completed at the department of Agroecology, Research Center Flakkebjerg, Faculty of Technical Sciences, Aarhus University.
