Major interests

Among plant-parasitic nematodes, the root-knot nematodes (RKNs) of the Meloidogyne spp. are the most economically important genus. RKN are root parasitic worms able to infect nearly all crop species and have a wide geographic distribution. During infection, RKNs establish and maintain an intimate relationship with the host plant. This includes the creation of a specialized nutritional structure composed of multinucleate and hypertrophied giant cells, which result from the redifferentiation of vascular root cells. Giant cells constitute the sole source of nutrients for the nematode and are essential for growth and reproduction. Hyperplasia of surrounding root cells leads to the formation of the gall or root-knot, an easily recognized symptom of plant infection by RKNs. Secreted effectors produced in nematode salivary glands and injected into plant cells through a specialized feeding structure called the stylet play a critical role in the formation of giant cells. Our group is interested in understanding the complex dialogue between RKNs (M. incognita and M. enterolobii) and their host plants using Arabidopsis and Solanaceae (tomato, tobacco) as model plants. We are studying both partners of the interaction in order to obtain a more comprehensive view of the plant functions corrupted by the pathogens and how RKNs manipulate key plant processes to their own profit. Thus, we characterized key regulators, essential for RKN-induced giant cell ontogenesis and nematode development: a protein implicated in microtubule reorganization (AtMAP65-3) (Caillaud et al., 2008), (homo)glutathione molecules (Baldacci et al, 2012) and the receptor of a signalling peptide PSK (AtPSKR1) (Rodiuc et al., 2015).

We are currently developing projects to (i) characterize RKN-specific effectors and their plant targets; (ii) explore the interplay between transcriptome, small RNAs and methylome in infected roots. Thus, we recently identified a small glycine and cysteine-rich secreted effector, MiSGCR1, involved in plant parasitism (Nguyen et al., 2018) and characterized the implication of a microRNA, miR159, in the plant response to the root-knot nematodes (Medina et al., 2017).
