Genome sequence of the coffee root-knot nematode Meloidogyne exigua

Root-knot nematodes (Meloidogyne spp.) cause serious damages on most crops. Here, we report a high-quality genome sequence of Meloidogyne exigua (population Mex1, Costa Rica), a major pathogen of coffee. Its mitogenome (20,974 bp) was first assembled and annotated. The nuclear genome was then constructed consisting of 206 contigs, with an N50 length of 1.89 Mb and a total assembly length of 42.1 Mb.

Automated summary

This study presents a high-quality genome sequence of Meloidogyne exigua, a major pathogen of coffee in Costa Rica. The nuclear genome was constructed with 206 contigs, providing valuable data for understanding the pathogenic mechanism of this nematode species.
