Genome structure and content of the rice root-knot nematode (Meloidogyne graminicola).

ABSTRACT: Discovered in the 1960s, Meloidogyne graminicola is a root-knot nematode species considered as a major threat to rice production. Yet, its origin, genomic structure, and intraspecific diversity are poorly understood. So far, such studies have been limited by the unavailability of a sufficiently complete and well-assembled genome. In this study, using a combination of Oxford Nanopore Technologies and Illumina sequencing data, we generated a highly contiguous reference genome (283 scaffolds with an N50 length of 294 kb, totaling 41.5 Mb). The completeness scores of our assembly are among the highest currently published for Meloidogyne genomes. We predicted 10,284 protein-coding genes spanning 75.5% of the genome. Among them, 67 are identified as possibly originating from horizo
