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

Período documentado: 2019-02-01 hasta 2021-01-31

Resumen del contexto y de los objetivos generales del proyecto

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.

Trabajo realizado desde el comienzo del proyecto hasta el final del período abarcado por el informe y los principales resultados hasta la fecha

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.

Avances que van más allá del estado de la técnica e impacto potencial esperado (incluida la repercusión socioeconómica y las implicaciones sociales más amplias del proyecto hasta la fecha)

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
