Genomic and Transcriptomic Analysis of the Polyploidy Cyst Nematode, <i>Heterodera trifolii</i>, and <i>Heterodera schachtii</i>.

ABSTRACT: Cyst nematodes remain a major threat to global agricultural production, causing huge losses. To understand the parasitism of the cyst nematodes Heterodera trifolii (HT) and Heterodera schachtii (HS), we constructed whole-genome assemblies using short- and long-read sequencing technologies. The nematode genomes were 379 Mb and 183 Mb in size, with the integrated gene models predicting 40,186 and 18,227 genes in HT and HS, respectively. We found more than half of the genes predicted in HT (64.7%) and HS (53.2%) were collinear to their nearest neighbor H. glycines (HG). Large-scale duplication patterns in HT and segmental duplications of more than half of the orthologous genes indicate that the genome of HT is polyploid in nature. Functional analysis of the genes i
