Rice (Oryza sativa L.) is not only a staple food but also a good model organism for monocot plants. Scarcity of fresh water is causing a shift to aerobic rice cultivation which benefits the distribution and infection of Meloidogyne graminicola, the most damaging root-knot nematode of rice [Kyndt et al., 2014, Annual Review of Phytopathology 52: 135-153). M. graminicola is a biotrophic pathogen with a sedentary life style and therefore it developed complex strategies to invade and survive in the roots for a long period. Nematode effectors secreted in the plant by the nematode are essential for successful parasitism. In our research, we are analyzing how nematode effectors suppress the plant defense response and interfere with plant hormone pathways [Yimer et al., 2018, New Phytologist 218: 646-660]. Assays triggering the early defense response of the plant demonstrate that effectors can suppress PTI (PAMP triggered immunity) [Naalden et al. 2018, Molecular Plant Pathology in press]. On the other hand, screening has identified rice varieties that are resistant to M. graminicola [Dimkpa et al., 2016, Journal of Experimental Botany: 67, 1191–1200] opening new research opportunities for the analysis of the rice-nematode interaction and opportunities to develop commercial varieties resistant to M. graminicola.
