The Plant Biology Option allows biology majors to focus their studies on plant science and to have this reflected on their transcript. There are a number of departments at UW–Madison who host plant science-based majors, including agronomy, botany, horticulture, plant pathology, and forest and wildlife ecology. While those specialized majors offer in-depth programs in their disciplines, the Plant Biology option allows students to pursue a course of study within the biology major and explore plant biology at the same time. Students in this option can fulfill their requirements with courses that emphasize various aspects of plant science, including anatomy, physiology, genetics, crop production, disease resistance, and molecular techniques in plant improvement. Students also participate in a one credit seminar called Frontiers in Plant Science taught by two faculty from plant science departments.

Who should enroll in this option? Students with broad interest in biological sciences who also want to:
  • Prepare for graduate work in a plant science field
  • Prepare for advanced study or graduate work in a natural or environmental science field
  • Concentrate their studies on the biology of plants

Courses may not double count within the major (unless specifically noted otherwise), but courses counted toward the major requirements may also be used to satisfy a university requirement and/or a college requirement. A minimum of 15 credits must be completed in the major that are not used elsewhere. Students must complete a minimum of 31 credits from Introductory Biology, Foundation, Intermediate/Advanced, Seminar (options only) and additional lab/research courses.
