Applicants for admission to the Plant Biology Graduate Group must present evidence of high intellectual achievement and possess the potential for successful graduate study. A level of scholastic achievement equivalent to that of a Bachelor's degree in biological sciences from a recognized college or university is required. An applicant must have a minimum 3.0 GPA to be considered for admission. The applicant must submit one official transcript for each school attended, three letters of recommendation and GRE scores from an exam taken within the last five years. A GRE subject test is recommended, but not required. There is no minimum GRE score.

TOEFL or IELTS scores are also required if the applicant's native language is not English or if prior instruction has not been in English; applicants must meet the minimum scores required by the Office of Graduate Studies, found here:

Though students do not need to take all of these courses in order to be admitted to the Plant Biology Graduate Group, the PBI highly recommends that students complete as many of these courses as possible before matriculating at UC Davis. Limited deficiencies can be made up after admission to the graduate program, generally during the student's first year. Admitted students work with their Graduate Advisers to identify any deficiencies and the courses necessary to fulfill these deficiencies. Early completion of these courses allows students to focus on their graduate studies and to expedite the completion of their graduate degrees.
