Abstract Global patterns of population genetic variation through time offer a window into evolutionary processes that maintain diversity. Over time, lineages may expand or contract their distribution, causing turnover in composition. At individual loci, migration, drift, environmental change (among other processes) affect allele frequencies. Museum specimens widely distributed species unique the genetics understudied populations and changes over time. Here, we sequenced genomes 130 herbarium...
Abstract Understanding the genetic basis of complex traits is a fundamental goal evolutionary genetics. Yet, genetics controlling in many important species such as hemp (Cannabis sativa) remain poorly investigated. Because hemp’s change legal status with 2014 and 2018 U.S. Federal Farm Bills, interest its numerous agriculturally has steadily increased. To better understand hemp, we developed an F2 population by crossing two phenotypically distinct cultivars (Carmagnola USO31). Using...
Abstract A comprehensive understanding of the degree to which genomic variation is maintained by selection vs. drift and gene flow lacking in many important species such as Cannabis sativa, one oldest known crops be cultivated humans worldwide. We generated whole genome resequencing data across diverse samples feralized (escaped domesticated lineages) lineages C. sativa. performed analyses examine population structure, genome-wide scans for FST, balancing selection, positive selection. Our...
High-throughput, field-based characterization of root systems for hundreds genotypes in thousands plots is necessary breeding and identifying loci underlying variation traits their plasticity. We designed a large-scale sampling pulling force, the vertical force required to extract system from soil, maize diversity panel under differing irrigation levels two growing seasons. then characterized architecture extracted crowns. found consistent patterns phenotypic plasticity subset differential...
