Selective sorting of ancestral introgression in maize and teosinte along an elevational cline

This study examines introgression patterns between maize and mexicana teosinte across an elevational gradient, finding ancient introgression from mexicana into maize that contributes to adaptation to high elevation environments.

Genome-wide sequence-based genotyping supports a nonhybrid origin of Castanea alabamensis

This study uses genome-wide SNP data to test if Castanea alabamensis is a hybrid of C. dentata and C. pumila, finding no evidence of hybridization and instead supporting a nonhybrid origin.
