Extrachromosomal circular DNA mediated spread of herbicide resistance in interspecific hybrids of pigweed
Plant Science Research WeeklyExtrachromosomal circular DNA (eccDNA) is a type of double-stranded circular DNA that is derived from chromosomes. High copy number and expression level of eccDNA encoding 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) have been linked with glyphosate resistance in pigweed (Amaranthus spp). Previous…
