Chromosome-Level Assemblies of the Allohexaploid Genomes of Conyza sumatrensis and Conyza bonariensis. [PDF]

Genome Biol Evol
Abstract Conyza sumatrensis and Conyza bonariensis are two important hexaploid weed species that impact crop production systems across the globe. Here, we report reference genome assemblies for both species. The sequenced accession of C. sumatrensis is resistant to multiple herbicides and was collected from the state of Paraná in Brazil,
