Unzipped genome assemblies of polyploid root-knot nematodes reveal unusual and clade-specific telomeric repeats.

Using long-read sequencing, we assembled and unzipped the polyploid genomes of Meloidogyne incognita, M. javanica and M. arenaria, three of the most devastating plant-parasitic nematodes.

Chromatin Landscape Dynamics in the Early Development of the Plant Parasitic Nematode Meloidogyne incognita.

In model organisms, epigenome dynamics underlies a plethora of biological processes. The role of epigenetic modifications in development and parasitism in nematode pests remains unknown. The root-knot nematode adapts rapidly to unfavorable conditions, despite its asexual reproduction.

Movements of transposable elements contribute to the genomic plasticity and species diversification in an asexually reproducing nematode pest.

Despite reproducing without sexual recombination, is an adaptive and versatile phytoparasitic nematode. This species displays a global distribution, can parasitize a large range of plants, and can overcome plant resistance in a few generations. The mechanisms underlying this adaptability remain poorly known.
