Nordbring-Hertz's research mainly dealt with a type of
microfungi, so-called
nematophagous fungi, that infect and digest nematodes. She concentrated on the nematode-trapping fungus
Arthrobotrys oligospora. Nordbring-Hertz used
scanning electron microscopy to study the trapping organs of
A. oligospora. Her early research was concentrated on how trapping organs were induced, apart from nematode touching the
hyphae also chemically by small
peptides will induce trap formation. Her work was later focussed on specific recognition mechanisms, e.g. by
lectins (
carbohydrate-binding
glycoproteins) on the trap surface that recognise specific carbohydrates on the nematode surface and start the infection process. Her research also examined
volatile exudates from nematodes, the fungal plant pathogen
Verticillium dahliae, and quantifying the presence of the fungus in
soil ecosystems. == Selected publications ==
