Abstract Arabidopsis thaliana (hereafter Arabidopsis) is a small plant with a fast generation time and a well-annotated genome, which makes it ideal for research labs. It is arguably the most used model species in basic plant sciences. Over the past half century, studies in Arabidopsis have generated enormous insight into fundamental principles of plant life, ranging from mechanistic molecular biology to the complexities of interacting ecosystems. Based on research in Arabidopsis, we now understand that while basic cellular metabolism is generally conserved across species, variation in specialized metabolite enzymes gives rise to complex bouquets of chemical weapons that are tightly interwoven with the environment. Understanding how these are produced, regulated, and—especially—how they are deployed remains a key research area for plant immunity. The breadth of work in Arabidopsis provides a unique window into this complicated aspect of life as a plant. We are happy to have an opportunity to share our common interest in these aspects in this review. Due to space constraints, we focus on compounds produced by Arabidopsis with demonstrated antimicrobial properties. We hope that this focus (despite our eagerness to write more) will inspire new avenues of research that will contribute to a more complete understanding of immunity.
