A High-Quality Genome Assembly of Johnsongrass Illuminates Relationships Between Polyploidization, Crop-Wild Hybridization, and Reproductive Biology

Abstract Johnsongrass [Sorghum halepense (L.) Pers.] is an allopolyploid, rhizomatous, perennial grass species and one of the most troublesome weeds in global agriculture. We assembled the first Johnsongrass genome to clarify poorly understood genetic factors influencing variable rates of crop-wild hybridization with c...

Rapid and repeated evolution of increased competitive ability in a global invader

Rapid adaptive evolution can increase the competitive ability of invasive species in their non-native ranges. However, whether this increase is a general response and what drives it remain uncertain because the evidence is largely based on studies with limited sampling, inadequate consideration of population co-ancestr...
