Interpretive Summary: This is a review article that discusses the need and importance of choosing model plant systems pertinent to the weed science community. The reason for the effectiveness of model plant systems in mainstream agriculture are discussed along with some of the vital characteristics common to all model plants. The current progress towards developing tools for several pioneer model weeds are noted, and other potential model weeds and approaches are suggested.

Technical Abstract: Plant model systems have contributed greatly to the dramatic progress in understanding fundamental aspects of plant biology. Using model weeds will also help facilitate focused funding and research in the weed science community. Criteria for developing model weeds require attention to weedy characteristics that impart economic losses, and a wide geographic distribution with the potential for political and scientific support. EST-databases for model weeds are the most practical approach to identify new genes and obtain data on gene expression underlying weedy characteristics. Weeds such as Canada thistle, eastern black nightshade, johnsongrass, jointed goatgrass, leafy spurge, waterhemp, and weedy rice are proposed as model systems.
