Key message The GWAS and testing with Yr gene linked markers identified 109 loci including 40 novel loci for all-stage and adult plant stage resistance to stripe rust in 459 US contemporary hard winter wheat genotypes. Abstract Stripe rust is a destructive wheat disease, caused by Puccinia striiformis f. sp. tritici ( Pst ). To identify sources of stripe rust resistance in US contemporary hard winter wheat, a panel of 459 Grea...

In this study, we used a comparative genome scan to examine patterns of population differentiation with respect to host plant use in Hesperotettix viridis, a Nearctic oligophagous grasshopper locally specialized on various Asteraceae including Solidago, Gutierrezia, and Ericameria . We identified amplified fragment length polymorphism (AFLP) loci with significantly elevated F ST (outlier loci) in multiple different‐host and sa...
