Periodic Reporting for period 1 - NemHatch (Unlocking mechanisms of cyst Nematode Hatching for sustainable cyst nematode control)

Okres sprawozdawczy: 2019-02-01 do 2021-01-31

Podsumowanie kontekstu i ogólnych celów projektu

Cyst nematodes worldwide attack agricultural crops such as potato, sugar beet, rice and soybean and cause large losses in their yield. There is a great need for developing new control methods for cyst nematodes because 1) resistance in cultivars is overcome, 2) crop rotation is problematic and 3) most of the nematicides are banned. Plant roots secrete triterpenoid-like signaling molecules into the soil that are known to induce hatching of cyst nematodes, called hatching stimulants (HSs). In NemHatch, I will develop a new strategy to control cyst nematodes by manipulating the signaling relation – mediated by the HSs - between the host plant and the cyst nematodes.
The overall goal of NemHatch was to generate the knowledge required for a new strategy to control cyst nematodes in agricultural crops by manipulating the signaling relation – mediated by the hatching stimulants - between the host plant and the cyst nematodes.

Prace wykonane od początku projektu do końca okresu sprawozdawczego oraz najważniejsze dotychczasowe rezultaty

1. HS was detected in about 20% of over 300 Petota accessions; some zero HS genotypes still induced high hatching suggesting an unknown hatching stimulant.
2. Analysis with our new ultrasensitive analytical method demonstrated variation in HS production in cultivated genotypes.
3. The QTL for HS production is interesting and candidate genes were selected.
4. HS production is influenced by eviromental conditions.

Innowacyjność oraz oczekiwany potencjalny wpływ (w tym dotychczasowe znaczenie społeczno-gospodarcze i szersze implikacje społeczne projektu)

For the first-time I detected the hatching stimulant in wild potato species. Under elevated temperature/climate change and low fertilizer input, the parasitic nematode activity may change
