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

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, while the accession of C. bonariensis was collected from California, USA. Genomic long read data was used along with optical mapping data to assemble the C. sumatrensis genome into a single haplome at chromosome-level contiguity. The same approach was used along with chromatin contact mapping data to phase the haplotypes of C. bonariensis and generate two chromosome-level haplome assemblies. Subgenome-specific sequences were identified and used to classify the thre
