Dear Editor:
The introduction of genetically engineered (GE) crops has resulted in a dramatic increase in the number of studies providing estimations and predictions of gene flow at various temporal and spatial scales. Before the work of Gustafson et al. (2005), no model existed concerning pollen-mediated gene flow (PMGF) in wheat. This led the authors to develop an empirical regression model that permitted generalized predictions regarding isolation distances, harvest blending, and the effects of field size on PMGF in wheat. However, we are compelled to write this letter ...
