The mission of the Undergraduate Program in Plant Biology is to provide a theoretical and practical foundation in plant biology at different levels of organization, from molecules to ecosystems. Suggested courses of study are provided below for further specialization in specific fields of plant biology. Faculty advisors can assist in selecting combinations of courses appropriate for advanced study in the fields below and other emerging areas.

Courses prerequisite to the major, courses used to satisfy major requirements, and the 7 units (for B.S. degree) related to the major must be taken for letter grades. Students may elect to take other courses on a Satisfactory (S)/No Credit (NC) basis. Refer to the Academic Regulations section of this catalog for additional information on “S/NC” grading. Information about this program is available on the CNAS UAAC website at cnasstudent.ucr.edu.

Students planning to transfer to UCR with a major in Plant Biology must have a minimum GPA of 2.7 in transferable college courses and “C” or higher grades in a year sequence of general chemistry and in courses equivalent to our BIOL 005A, BIOL 005B. We also require that transfer students complete two quarters of college calculus (equivalent to our MATH 007A and 007B or our MATH 009A and MATH 009B) before admission. Exceptions may be granted by the faculty advisor.

See Undergraduate Studies section.

See College of Natural and Agricultural Sciences, Colleges and Programs section.

Some of the following requirements for the major may also fulfill some of the college’s breadth requirements. Consult with a department advisor for course planning.

The major requirements for the B.S. and B.A. degrees in Plant Biology are as follows:

• 1. Plant Biology core requirements (68-73

units)

Students must complete all required courses with a grade of “C-” or better and with a cumulative GPA in the core courses of at least 2.0. Grades of “D” or “F” in two core courses, either separate courses or repetitions of the same course, are grounds for discontinuation from the major.

• a) BIOL 005A, BIOL 05LA or BIOL 020, BIOL 005B, BIOL 005C

• b) CHEM 001A, CHEM 01LA, CHEM 001B,

The Department of Botany and Plant Sciences offers programs leading to the M.S. and Ph.D. degrees in Plant Biology. Research in these programs can focus on basic and/or applied questions.

Admission Applicants who have a baccalaureate degree and who satisfy the general requirements of the university listed in the Graduate Studies section of this catalog are considered for admission to graduate status. Students applying to the M.S. and Ph.D. program must submit GRE General Test scores (verbal, quantitative, and analytical).

Regardless of the area of their major for the baccalaureate degree, students must have had, or complete soon after entering graduate school the following:

• 1. A year of course work in general biology

• 2. A year of course work in general chemistry

• 3. A course in genetics
• 4. A course in biochemistry or ecology

• 5. A course in calculus

• 6. Two courses in physics and/or statistics

Credit from these courses does not count toward the graduate degree.

Immediately after being admitted, each student should identify a faculty advisor and consult with that advisor or the graduate advisor regarding educational goals; scheduling initial course work and possible lab rotations; and forming a guidance committee. Further guidance on these matters is provided in the Botany and Plant Sciences Graduate Student Handbook.

The Department of Botany and Plant Sciences offers programs leading to the M.S. degree in Plant Biology.

The master’s degree may be earned under Plan I (Thesis) or Plan II (Comprehensive Examination). Students must meet all general requirements of the Graduate Division. The detailed course program is determined by the guidance committee after considering the specific interests of the student. Department requirements are as follows:

Plan I (Thesis)

• 1. Three courses from Section I are required.

Students who have taken courses comparable to those in Section I during their baccalaureate training may have a portion or all of this section waived. Recommendations for waivers should specify alternative courses and should be sent to the department educational advisory committee for approval. In such instances, however, it is expected that their programs include increased units in courses from Sections II, III, and/or IV.

• 2. Two courses (6 units) from Section II are

required. In fulfilling the Section II requirement, students may use no more than one course cross-listed by Botany and Plant Sciences and another program. If such a cross-listed course is used toward fulfilling the Section II requirement, the same course may not be used toward fulfilling the Section I or III requirements. No more than four units may be in professional development courses.

• 3. At least 6 units from Section III must

be taken.

• 4. Preparation of a thesis: Not more than

12 units from Section V (299 units) may apply toward the degree. If the student takes research courses (290/297) from Section IV, not more than 6 units may be applied toward the degree. A total of 12 units of 297/299 may be used towards the degree.

Seminar Requirement All full-time students must enroll in the BPSC 250 seminar during each quarter in which it is offered. Part-time students must take one BPSC 250 seminar for every 12 units of courses. All students must present at least one BPSC 250 seminar and complete at least one quarter of BPSC 240 (or approved similar equivalent that involves substantial student presentations). Plan II (Comprehensive Examination)

• 1. Three courses from Section I are re

quired. Students who have taken courses comparable to those in Section I during their baccalaureate training may have a portion or all of this section waived. In such instances, however, it is expected that their programs include increased units in courses from Section II and/or III. Recommendations for waivers should specify alternative courses and should be sent to the educational advisory committee for approval.

• 2. Two courses (6 units) from Section II are

required. In fulfilling the Section II requirement, students may use no more than one course cross-listed by Botany and Plant Sciences and another program. If such a cross-listed course is used toward fulfilling the Section II requirement, the same course may not be used toward fulfilling the Section I or III requirements. No more than 4 units may be in professional development courses.

• 3. At least 3 courses (11-12 units) from

Section III are required.

• 4. Students must complete at least 6 units

from Section IV for a research project (297) or literature review (290), which should be described in a report to be submitted for evaluation by the comprehensive examination committee.

• 5. Comprehensive written and

oral examinations

The Department of Botany and Plant Sciences offers programs leading to the Ph.D. degree in Plant Biology.

The student must meet the general requirements of the Graduate Division.

Admission Either prior to entering the graduate program or before advancement to candidacy, students must have completed the equivalent of BPSC 104 and one other course from the core plant biology courses (BIOL 107A, BPSC 132, BPSC 135, BPSC 138, BPSC 143, BPSC 146). Course requirements for each student are determined by individual guidance committees and by the educational advisory committee. No later than the second quarter in residence, students meet with a guidance committee to (1) determine a course program to be submitted to the educational advisory committee,and (2) choose a major area of specialization and two minor areas.

Course Work Guidance committees and students should design individual course programs that meet the specific needs of the student and the requirements of the Ph.D. program. Course programs should prepare students for the qualifying examination and dissertation research. All first-year students must enroll in BPSC 200A and 200B during their first Fall and Spring quarters. Students must take a minimum of 3 graduate-level courses (11-12 units) relevant to the specialization. Graduate courses taken previously may be considered towards fulfilling this requirement. Students’ course programs must be approved by the educational advisory committee. At the time of submission of course programs to the educational advisory committee, the area of specialization and two minor areas to be covered on the qualifying examination should be specified. Students may petition to change the course program, area of specialization, or minor areas at any time.

Students entering the Plant Biology Ph.D. program have four choices, as listed below. Students with a general interest in plant biology and/or evolution are encouraged to choose the first.

Ph.D. in Plant Biology Students who choose to obtain a Ph.D. in Plant Biology without one of the following concentrations are encouraged to – with the advice and consent of their Major Professor and Guidance Committee – select a set of graduate-level courses (11-12 U) that is specifically tailored to their individual research interests and career objectives. Students can also choose from one of three concentrations:

Ph.D. in Plant Biology (Concentration in Plant Cell, Molecular, and Developmental Biology) To earn the concentration in Plant Cell, Molecular, and Developmental Biology (appears on the transcript only), students must complete BPSC 231, and BPSC 235. In addition, the required BPSC 240 course must be on a topic related to the concentration.

Ph.D. in Plant Biology (Concentration in Plant Ecology) To earn the concentration in Plant Ecology (appears on the transcript only), students must complete one course relating to the conceptual hierarchy of ecology (BPSC 243, BPSC 245, BPSC 246, EEOB 211), one course in quantitative methods (BPSC 225J, EEOB 230, BPSC 247, EEOB 215, STAT 231 A or B, PSYC 211, 212, or 213), one BPSC 240 course, and four additional 200-level units chosen in an area that supports the concentration.

Ph.D. in Plant Biology (Concentration in Plant Genetics) To earn the concentration in Plant Genetics (appears on the transcript only), students must complete three graduate-level courses (11-12 units) relating to Genetics. Required courses must include two courses from the following list: BPSC 221, BPSC 222, BPSC 225K, BPSC 231, BPSC 234, EEOB 214, BIOL 221/MCBL 221/PLPA 226, GEN 240A. The additional units can be chosen in an area that supports the concentration. In addition, the required BPSC 240 course must be on a topic related to the concentration.

Written and Oral Qualifying Examinations Advancement to candidacy depends on the student passing written and oral qualifying examinations. The qualifying examination covers the student’s area of specialization and two minor areas. Granting of the degree is contingent upon acceptance of the dissertation by the candidate’s dissertation committee and satisfactory oral defense of the dissertation.

Oral Qualifying Exam and Final Defense Modality In-person oral qualifying exams and dissertation defense are strongly recommended, and every effort should be made to hold these discussions in person. However, if unusual circumstances exist that prohibit a fully in-person meeting, a hybrid or fully online option should be made available, in agreement with the committee chair and student, and approval by the graduate advisor (who may find it necessary to consult with the Graduate Educational Advisory Committee). If the oral qualifying exam and/or dissertation defense has been scheduled for in-person, but a committee member has emergency circumstances, then remote accommodation should be made available for that faculty member. The priority should be to hold the exam and/or defense on the originally scheduled day, unless extenuating circumstances prevent this.

Committee members nominated from outside the UC Academic Senate who participate remotely must have qualifications comparable to a UC Academic Senate member and submit a letter of intention and CV. In addition, strong academic justification for inclusion on the committee must be provided by the Graduate Advisor.

Seminar Requirement All candidates must enroll in the BPSC 250 seminar during each quarter in which it is offered until advancement to candidacy. After this time, PhD candidates must enroll in BPSC 250 seminar two quarters per year until conferral of the degree. The dissertation defense is normally presented in the BPSC 250 seminar series; however, if necessary, a special seminar may be scheduled for the defense. Also, students must present at least one BPSC 250 seminar in addition to the defense of the dissertation. All students must complete at least one quarter of BPSC 240 (or approved equivalent that involves substantial student presentations) during the Ph.D. program.

Professional Development Training Ph.D. graduate students must enroll in BPSC 200A and BPSC 200B to fulfill their professional development training requirement. Students may enroll in BPSC 200C to develop skills in research mentoring in the life sciences.

Foreign Language Requirement None

Teaching Requirement Students must obtain at least two quarters of teaching experience.

Normative Time to Degree 15 quarters

Normative Time to Candidacy 2 years
