Interpretive Summary: This book chapter reviews various aspects of what is needed for the selection of model weeds to answer questions pertinent to weed science. Specifically, the chapter covers why we need model species, attributes of model species, and provides the current state of knowledge and resources that have been developed for a few key weeds such as leafy spurge, Canada thistle, waterhemp, and purple false brome that may make them good potential models.
Selection of a limited number of model weeds and development of genomic-based tools and resources will facilitate studies on the ecology, biology, physiology and development of weedy species. Such studies will help answer fundamental questions of concern to weed scientists. However, to ensure the weed science community can appropriately and fully utilize these model weeds, they will need to be carefully selected. Various attributes such as ease of study, weedy characteristics, and importance as a weedy species will need to be considered. Additionally, the availability of existing genomic resources can be used to extend the list of viable model weeds. Several resources have also been developed specifically for weeds such as leafy spurge, Canada thistle, waterhemp, and purple false brome.
