Abstract

Where do weeds come from? How do they evolve from nonweedy ancestors? In this issue of Molecular Ecology, Londo and Schaal examine the origin of weedy rice (Oryza sativa) populations in the USA. Analysing nuclear DNA sequence and microsatellite data, they show the importance of parallel evolution, hybridization, gene flow, and migration in the evolution of these weeds.
