| Abstract/Contents: | "Target-site gene copy number variation (CNV) of 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) has repeatedly been associated with resistance to glyphosate in many agronomic weeds, including the economically important grass, Eleusine indica (goosegrass). However, the origin of these CNVs previously remained elusive in goosegrass due to limited genomic resources. To investigate this CNV in goosegrass, we produced high-quality reference genomes for glyphosate-susceptible and -resistant goosegrass lines and fine-assembled this CNV. We reveal a unique translocation of EPSPS and a distant genomic region into the subtelomere region and subsequent duplication of these two regions in the subtelomere resulting in glyphosate resistance in goosegrass. This discovery emphasizes the importance of subtelomeres as genetic variation generators in plants and provides another unique example of herbicide resistance evolution." |
