Mitosis which is a major step during plant development can also be observed in physiopathological conditions. During the compatible interaction between the root-knot nematode Meloidogyne incognita and its host Arabidopsis, the pathogen induce through repeated divisions without complete cytokinesis the formation of hypertrophied and...
Les plantes disposent d'une immunité naturelle qui leur permet de résister aux maladies et aux agressions parasitaires dans leur environnement. L'invention puis le développement de l'agriculture ont cependant créé des milieux très favorables à l'émergence de nouvelles maladies et au développement des épidémies. Cette vulnérabilité sanitaire...

Cet ouvrage très didactique présente, sous forme de fiches, les principales techniques utilisées dans les laboratoires pour étudier le fonctionnement du vivant via les acides nucléiques. Après quelques définitions et généralités sur la structure des gènes, on y décrit les techniques de base en biologie moléculaire et génomique. Ces techniques...

Plant parasitic nematodes are microscopic worms, the most damaging species of which have adopted a sedentary lifestyle within their hosts. These obligate endoparasites have a biotrophic relationship with plants, in which they induce the differentiation of root cells into hypertrophied, multinucleate feeding cells (FCs). Effectors synthesized in...

Plant-parasitic root-knot and cyst nematodes are microscopic worms that cause severe damage to crops and induce major agricultural losses worldwide. These parasites penetrate into host roots and induce the formation of specialized feeding structures, which supply the resources required for nematode development. Root-knot nematodes induce the...
Small plant signalling peptides play key roles in plant development and in plant–microbe interactions. The plant CLAVATA3 (CLV3)/ENDOSPERM SURROUNDING REGION (ESR) (CLE) peptides have been shown to orchestrate shoot meristem differentiation and to be involved in root growth and vascular development (Yamaguchi et al., 2016). CLE peptides have...
SUMMARY Taxonomy: Eukaryota; Metazoa; Nematoda; Chromadorea; order Tylenchida; Tylenchoidea; Heteroderidae; genus Meloidogyne. Physical properties: Microscopic‐non‐segmented worms. Meloidogyne species can reproduce by apomixis, facultative meiotic parthenogenesis or obligate mitotic parthenogenesis. Obligate biotrophic parasites inducing the...
Novel approaches for the control of agriculturally damaging nematodes are sorely needed. Endoparasitic nematodes complete their life cycle within the root vascular cylinder, inducing specialized feeding cells: giant cells for root-knot nematodes and syncytia for cyst nematodes. Both nematodes hijack parts of the transduction cascades involved...
Root-knot nematodes (RKNs), genus Meloidogyne, are widespread, polyphagous endo-parasites which present a serious and growing threat to agriculture. They have evolved sophisticated strategies for exploiting plants, and research on nematode parasitism therefore tackles fundamental questions in plant development and host defence. These obligate...
