Chromosome-level reference genome of X12, a highly virulent race of the soybean cyst nematode Heterodera glycines.

Soybean cyst nematode (SCN, Heterodera glycines) is a major pest of soybean that is spreading across major soybean production regions worldwide. Increased SCN virulence has recently been observed in both the United States and China. However, no study has reported a genome assembly for H. glycines at the chromosome scale. Herein, the first chromosome-level reference genome of X12, an unusual SCN race with high infection ability, is presented. Using whole-genome shotgun (WGS) sequencing, PacBio sequencing, Illumina paired-end sequencing, 10X Genomics linked reads and high-throughput chromatin conformation capture (Hi-C) genome scaffolding techniques, a 141.01-Mb assembled genome was obtained with scaffold and…
