The Plant Biology Graduate Program offers the master's degree without thesis (M.S.), the master's degree with thesis (M.S.), and the doctoral degree (Ph.D.). Required undergraduate preparation normally includes calculus, general and organic chemistry, physics, general biology or equivalent, genetics, and some botanical training. Students with strong academic records and other evidence of scholarly talents or promise are encouraged to apply. Submission of the Graduate Record Examination score is required and an appropriate subject test score is strongly recommended (example: biology, cell and molecular, ecology, or biochemistry). A variety of fellowships and teaching and research assistantships are available.
