Plant-parasitic nematodes are among the biggest threats to various crops essential for global food security. About 10% of the world's crop losses are estimated to result from these microscopic worms. The deployment of resistance genes has been a primary method used to control nematodes. However, resistance genes create a selection pressure that can lead to resistance-breaking nematode populations. Since there are only a limited number of resistance genes available, there is a dire need to find ways to delay resistance breakdown.

Our project aims to understand the genetic factors and evolutionary strategies behind the competition among nematodes for access to plant roots. We will study this in four nematode species: Ditylenchus dipsaci, Meloidogyne hapla, Globodera pallida, and Globodera rostochiensis. Additionally, we will examine competition among nematodes of the same species (intraspecific competition) and between different species (interspecific competition). This knowledge may allow us to predict nematode interaction responses, potentially extending the effectiveness of resistance genes. Therefore, this project offers an innovative approach to managing these highly damaging pests.
