| Abstract/Contents: | "Genomic structural variation (SV) can have profound effects on an organism's evolution. Copy number variation (CNV), a source of SV, is associated with adaptive evolution in eukaryotes. Resistance to the most widely used herbicide, glyphosate, has evolved through CNV in many weedy plant species, including the economically important cosmopolitan grass, Eleusine indica (goosegrass). We obtained high-quality reference genomes for both glyphosate-susceptible and -resistant goosegrass, fine assembled the duplication of glyphosate's target site gene enolpyruvylshikimate-3-phosphate synthase (EPSPS), and revealed a novel instance of subtelomeric CNV of EPSPS leading to herbicide resistance evolution. Therefore, the association of subtelomeric CNV with adaptive evolution is evident in E. indica, adding to limited knowledge of the importance of subtelomeres as rearrangement hotspots and novel variation generators. We hypothesize glyphosate resistance is conferred by the translocation of EPSPS from its native location on chromosome three into the subtelomeric region and subsequent duplication in this region." |
