The intercollegiate faculty of Molecular and Environmental Plant Sciences (MEPS) has members in the College of Agriculture and Life Sciences and the College of Arts and Sciences. Degree programs are available leading to a Master of Science (MS) and Doctor of Philosophy (PhD) degree in Molecular and Environmental Plant Sciences. Program requirements are determined and supervised by MEPS faculty. Degree programs are prepared on an individual basis by the graduate students in consultation with their advisory committee. For administrative purposes, students hold appointments in their major professor's department.

Traditionally, plant scientists have been interested in the improvement of agriculture, and many of the most basic findings on photoperiodism, mineral nutrition, plant growth regulators, morphogenesis, postharvest physiology and plant competition have had major effects on modern agriculture. Today, the unifying goals of plant science are to

• improve plants
• understand their biology, behaviors and environmental interactions
• enhance our ability to use plants in meeting society’s many needs

Attaining these goals requires significant interdisciplinary interactions, e.g., with molecular genetics, genomics, plant breeding, bioinformatics, phenomics, data science, environmental physics, agronomy and other plant-agriculture disciplines.

Graduate degree programs are individually designed to prepare graduates for careers in specialized areas of the discipline, including molecular biology, metabolism, development, physiological ecology and environmental or crop physiology. Faculty members hold appointments in the Departments of Atmospheric Sciences, Biochemistry and Biophysics, Biology, Biological and Agricultural Engineering, Ecology and Conservation Biology, Entomology, Horticultural Sciences, Plant Pathology and Microbiology, and Soil and Crop Sciences. Courses in these departments support the curriculum along with those in Chemistry, Genetics, Mathematics, Physics and Statistics.

All graduate students participate in the student seminar program and take at least two core MEPS courses to deepen their knowledge of plant physiology, ecological plant physiology, plant biochemistry and plant molecular biology. The degree program offers a high degree of flexibility, allowing student to tailor coursework to their research needs and career goals.

Student’s Advisory Committee

After receiving admission to graduate studies, students will consult with the graduate program concerning selection of a chair and members (if applicable) for an advisory committee representative of the student’s field(s) of study and research.

The student’s advisory committee for the MS degree will consist of no fewer than three members of the graduate faculty, representative of the student’s fields of study and research. The chair or the co-chair of the advisory committee must be from the student’s major department (or intercollegiate faculty, if applicable), and at least one or more of the members must have an appointment to a department other than the student’s major department. The outside member for students in an interdisciplinary program must have an appointment to a department different from the chair of the student’s committee. The chair, in consultation with the student, will select the remainder of the advisory committee. The student will interview each prospective committee member to determine whether he or she is willing to serve.

A Master of Science in Molecular and Environmental Plant Sciences student’s advisory committee will consist of no fewer than three members, where the chair or co-chair must be from the student’s intercollegiate faculty. At least one or more of the members must have a primary appointment with an academic unit external to the student’s major department. The External Member for a student in an interdisciplinary degree program must be from an academic unit different from the chair of the student’s advisory committee. The chair, in consultation with the student, will select the remainder of the advisory committee.

Only members of the Graduate Committee Faculty located on Texas A&M University campuses may serve as chair of a student’s advisory committee. Other members of the Graduate Committee Faculty – including those located off-campus or outside the university (if permitted by program, department, and college/school policy) – may serve as a co-chair or member, but not as chair.

The advisory committee as a group – and as individual members – are responsible for advising students on academic matters. These duties include the responsibility for approving a student’s proposed degree plan; research proposal (if applicable); thesis, dissertation, or record of study (if applicable); and conducting examinations (if required). The advisory committee members’ approval of a degree plan indicates their willingness to accept the responsibility for guiding and directing a student’s entire academic program and for initiating all academic actions concerning a student. Additionally, in cases of academic deficiency, the advisory committee is responsible for initiating recommendations to the academic unit and the Graduate and Professional School.

The chair of an advisory committee, who usually has immediate supervision of a student’s degree program, has the responsibility for calling meetings at any time considered desirable.

If the chair of a student’s advisory committee is unavailable for an extended period of time in any academic period during which the student is involved in activities relating to an internship, thesis or professional paper – and is registered for courses such as 684 (Professional Internship), 691 (Research), 692 (Professional Study) or 693 (Professional Study) – the Department Head or interdisciplinary degree Program Chair (if applicable) may appoint an alternate advisory committee chair during the interim period.

If a student’s advisory committee chair is on an approved leave of absence – and the student wants the chair to continue to serve in this role – a written request must be submitted by the Department Head, or interdisciplinary degree Program Chair (if applicable), to the Associate Provost and Dean of the Graduate and Professional School,  for the faculty member who is on an approved leave of absence to be allowed to continue serving as chair of the advisory committee – without a co-chair – for up to one year. The request must confirm that the faculty member is able to engage in the required duties as chair during the leave of absence. Extensions beyond the one-year period (if necessary) may be granted with additional approval of the Associate Provost and Dean of the Graduate and Professional School.

If a student’s advisory committee chair voluntarily separates from the university, and the student is nearing completion of the degree, the chair may continue to serve in this role – at the student’s request – for up to one year. Two options are available:

1. The chair may continue, with a co-chair, without additional approval by the Graduate and Professional School. The student must select a current member of the Graduate Committee Faculty – from the student’s academic program and located near the Texas A&M University campus site – to serve as co-chair of the advisory committee.
2. The chair may continue, without a co-chair, with approval by the Graduate and Professional School. A written request must be submitted through the Graduate Committee Faculty Office to the Associate Provost and Dean of the Graduate and Professional School by the Department Head or interdisciplinary degree Program Chair to allow the faculty member to continue as chair, without a co-chair, of the advisory committee.

For both options, extensions beyond the one-year period (if necessary) may be granted with approval of the Associate Provost and Dean of the Graduate and Professional School.

Although individual members may be replaced by petition for valid reasons, all members of a student’s advisory committee cannot resign en masse.

Degree Plan

Upon commencement of graduate studies, an advisory committee will evaluate the student’s previous education, and outline a program of study and/or research topics(s) based upon the student’s degree objectives. Graduate students, in consultation with the advisory committee, will then develop a degree plan which includes those courses to be applied toward a particular degree and formally establish the advisory committee. 

The degree plan must be created, submitted, and approved through the online Document Processing Submission System (DPSS). The degree plan must be submitted prior to the deadline imposed by the student’s college or school and approved by the Graduate and Professional School no later than 90 days prior to the last day for completion of a Final Examination. Students must select the appropriate program option(s) when submitting a proposed degree plan.

Coursework included on the degree plan is subject to the requirements and restrictions detailed in the Credit Requirements and Limitations on Credits and Coursework sections in each degree program page, or as required by the student’s advisory committee and/or academic unit. Coursework included on the degree plan may not satisfy requirements for more than one degree, except for approved combination degree programs.

Changes to an approved degree plan, if deemed necessary by the advisory committee, may be made through a petition to the Graduate and Professional School. No changes can be made to a degree plan once a student’s Final Examination Request or Final Examination Exemption Request is approved by the Graduate and Professional School.

Degree program time limits apply to courses listed on a degree plan. For additional information, students should check the Time Limits section under Additional Requirements.

Credit Requirements

All graduate students must complete sufficient semester credit hours to satisfy their degree requirements.

A minimum of 32 semester credit hours of approved courses and research is required for the thesis option Master of Science in Molecular and Environmental Plant Sciences.

A minimum of 36 semester credit hours of approved coursework is required for the non-thesis option.

Coursework may be completed in one or a combination of academic units. Ordinarily, students will devote the major portion of their time on work in one or two closely related fields of study; but other work may be required in supporting areas of interest.

Limitations on Credits and Coursework

Credit hour requirements for all graduate degrees at Texas A&M University are subject to the following limitations:

1. To receive a graduate degree, students must earn one-third or more of the credits through the institution’s own direct instruction. These limitations also apply to joint degree programs.

The foregoing limitations apply to all graduate programs. Exceptions will be permitted only in unusual cases, when petitioned through the student’s advisory committee, and approved by the Graduate and Professional School.

Research Proposal

Candidates for all thesis option master’s degrees must submit a Research Proposal.

The general field of research to be used for a thesis should be agreed on by the student and the advisory committee as a basis for selecting the proper courses to support the proposed research. Once the research project can be outlined in reasonable detail, the Research Proposal should be completed.

Compliance issues must be addressed before completion of a Research Proposal if a graduate student is performing research involving human subjects, animals, infectious biohazards, or recombinant DNA. Students engaged in these types of research should check with the Office of Research Compliance and Biosafety to address questions about all research compliance responsibilities before the proposal is submitted to the Graduate and Professional School. Additional information may be obtained at the Office of Research Compliance and Biosafety website.

The Research Proposal should be finalized at a meeting of the student’s advisory committee, at which time the feasibility of the proposed research and the adequacy of available facilities should be reviewed. Once completed, the Research Proposal must be submitted to the Graduate and Professional School via the Academic Requirements Completion System (ARCS).

For thesis option master’s degrees, a Research Proposal must be submitted to the Graduate and Professional School via ARCS at least 20 working days prior to the submission of a Final Examination Request, or by the date established in the Graduate and Professional School Dates and Deadlines calendar – whichever comes first.

Final Examination

Candidates for all thesis-option and certain non-thesis option master’s degrees must pass a Final Examination by deadlines announced through the Graduate and Professional School Dates and Deadlines Calendar.

Master's students may be given only one opportunity to repeat a Final Examination, and that must be within a time period that does not extend beyond the conclusion of the next regular semester (summer terms excluded).

Eligibility

For master’s degree students, eligibility to schedule a Final Examination requires that

1. a student’s cumulative and degree plan GPA must be at least 3.00;
2. no unabsolved grades of D, F or U for any course may be listed on a degree plan (to absolve a deficient grade, the student must repeat the course at Texas A&M University and achieve a grade of C or better); and
3. all coursework on the degree plan must be completed, with the exception of those hours for which the student is registered.

Master’s students may be given only one opportunity to repeat a Final Examination, and that must be within a time period that does not extend beyond the conclusion of the next regular semester (Summer terms excluded). 

Thesis Option Degrees

For thesis option students, a Final Examination is required.

The Final Examination may not be administered until the thesis is available in substantially final form to all members of a student’s advisory committee and all members have had adequate time to review the manuscript. The examination may cover the thesis and all work taken on a Degree Plan.

Thesis option students must be registered at the university in the fall, spring or summer term in which the Final Examination is taken.

An academic unit may have stricter requirements provided there is consistency among all degree programs within the college/school or department.

Non-Thesis Option Degrees

For non-thesis option students, a Final Examination may be required.

The examination cannot be held prior to the mid-point of the student's final semester if questions on the Final Examination are based on courses in which the student is currently enrolled.

If a student has completed all required degree plan coursework, the student is not required to register for classes in the semester a Final Examination is administered (unless the student holds a graduate assistantship).

Final Examination Exemptions

Thesis and non-thesis option candidates may petition to be exempt from the Final Examination – provided the Degree Plan GPA is 3.50 or greater – with approval of the advisory committee, the academic unit, and the Graduate and Professional School. Requests for exemption from the Final Examination must be submitted the same semester the student intends to graduate.

Scheduling

The Final Examination request must be submitted to the Graduate and Professional School via the Academic Requirements Completion System (ARCS) a minimum of ten (10) working days in advance of the requested examination date, or the deadline listed on the Graduate and Professional School Dates and Deadlines Calendar – whichever comes first. Any changes to the Degree Plan must be approved by the Graduate and Professional School prior to submission of the request.

Any cancellations will be notated in ARCS.

Format

The Final Examination shall be conducted by the student’s advisory committee as approved on a graduate degree plan, and the format shall be determined by the student’s academic unit and/or advisory committee and communicated to the student in advance of the examination. The Final Examination may consist of a written component, oral component, or combination of both.

The examination may cover the broad field of the candidate’s training and closely related topics. For doctoral and thesis master’s students, it is presumed that the major portion of the time will be devoted to the thesis, dissertation, or record of study (as applicable).

Only one committee member substitution is allowed – with prior approval of the Graduate and Professional School – to provide an evaluation decision for a student’s Final Examination. The advisory committee Chair may not be replaced by a substitute. If the degree program requires the advisory committee to include at least one External Member, and the substitution is for the sole external member of the advisory committee, then the substitute must also be external to the chair’s academic unit. In extenuating circumstances, with approval of the Graduate and Professional School, an exception to this requirement may be granted.

Persons other than members of the advisory committee may – with mutual consent of the candidate and the advisory committee chair – attend Final Examinations. Upon completion of a candidate’s questioning, all visitors must excuse themselves from the proceedings.

Grading

A positive evaluation of the Final Examination by the members of a student’s advisory committee – with at most one dissension – is required to pass a student on the examination. If the chair is the sole member of the student’s advisory committee, a positive vote is required to pass a student on the Final Examination. Academic units may have stricter requirements provided there is consistency in all degree programs within a given department or interdisciplinary degree program.

Final Examination results must be reported to the Graduate and Professional School via ARCS within ten (10) working days of completion of the examination.

Expiration

For restrictions on Final Examination validity, please see the Time Limits section under Additional Requirements.

Thesis

Candidates for all thesis option master’s degrees must complete an acceptable thesis.

A master’s thesis must reflect a comprehensive understanding of the pertinent literature and express in clear language the problem(s) for study, method, significance, and results of the student’s original research.

Manuscript formatting must be acceptable to the Graduate and Professional School as outlined in the Guidelines for Theses, Dissertations, and Records of Study.

After a successful Final Examination/defense (or Final Examination Exemption for thesis option master’s students, if permitted), and approval of the student’s advisory committee and the Department Head (or interdisciplinary degree Program Chair, if applicable), the student must submit the manuscript in electronic format as a single PDF file to the Thesis and Dissertation Submission System (Vireo).

A manuscript determined by the Graduate and Professional School to require corrections will be returned to the student. The student must make all necessary corrections and resubmit a revised version of the manuscript, which will be re-reviewed. All original submittal deadlines must be met during the resubmittal process to clear for graduation.

Additionally, a Written Thesis/Dissertation Approval Form must be submitted through the Academic Requirements Completion System (ARCS). Both the PDF file of the manuscript in Vireo, and the completed ARCS approval form, must be received by the Graduate and Professional School by the deadlines announced each semester or Summer term in the Graduate and Professional School Dates and Deadlines Calendar. Please see the Time Limits section in the Graduate and Professional Catalog.

Each student who submits a manuscript for review is assessed a one-time thesis/dissertation/record of study processing fee through Student Business Services for the review services provided. After commencement, manuscripts are digitally stored and made available through the Texas A&M Libraries.

Additional Requirements

• Continuous Registration
• Residence
• Scholastic Requirements
