Development of a low-coverage whole genome sequencing screen for apomixis using a diverse set of Malus germplasm

This low-pass screening-by-sequencing method is a relatively low-cost, rapid method for detecting apomictic genotypes in diverse plant germplasm and when used thoughtfully in conjunction with flow cytometry, provides a new way to visualize the genetic outcomes of sexual and asexual reproduction in plants.

New genomic resources and local adaptation GWAS in wild Malus angustifolia reveal genetic regions for enhancing abiotic resiliency in apple

This work used a combination of the latest genome sequencing and resequencing approaches to assemble a high-quality reference genome for Malus angustifolia, a native apple to the Southeastern U.S., and resequence its germplasm to enable genome-wide association study identify regions and structural variants associated w...

Assembly of Silphium interspecific hybrid genomes opens the genus to phylogenomics, ecogenomics, and molecular breeding

Wild perennial plants can be domesticated to make agriculture more diverse and resilient, but many have large genomes that have been recalcitrant to analysis. Here, we report phased genome assemblies for Silphium integrifolium Michx. and S. perfoliatum L., two species native to North America under domestication, and de...
