About Meloidogyne incognita

The nematode Meloidogyne incognita, also known as the southern root-knot nematode, is able to infect the roots of almost all cultivated plants. It is an obligatory sedentary parasite that reproduces by mitotic parthenogenesis. M. incognita can infect Arabidopsis thaliana, making it a key model system for the understanding of metazoan adaptations to plant parasitism.

Genome assembly: ASM18041v1a

The M. incognita genome project is coordinated by the French National Institute for Agricultural Research (INRA), with sequencing and assembly performed by the French National Sequencing Centre (Genoscope). The 'Morelos' isolate, from the root-knot nematode stock collection held at INRA, was selected for sequencing. The gap-free contigs from the assembly have been deposited with the INSDC (GCA_000180415.1). The authors have also produced a higher-level assembly that arranges the contigs into higher-order scaffolds. This higher-level assembly was used as the basis for analysis for publication (Abad et al 2008). It has not yet been submitted to INSDC.

Gene annotation

The gene predictions were made by Genoscope, as described by Abad et al (2008). The gene set version represented here is that submitted directly to WormBase in early 2014.

What can I find? Protein-coding and non-coding genes, splice variants, cDNA and protein sequences, non-coding RNAs.

Comparative genomics

What can I find? Orthologues, paralogues, and gene trees across multiple species.
