The Department of Botany offers graduate work leading to the degrees of Master of Science, Master of Agriculture, Master of Science in Teaching, and Doctor of Philosophy. Specific areas of specialization in botany include anat- omy/morphology with emphasis on tropical ferns, aquatic and woody plants, and orchids; bryology; development of seed plants, protoplast, cell and tissue culture; ecology and environmental studies; cellular and molecular genet- ics; mycology with emphasis on morphology, systematics, and development; algology with emphasis on algae of brine ponds; physiology and biochemistry with emphasis on ion uptake, photosynthesis and photorespiration, sugar metabolism and transport, growth and development of selected fungi, calcium-binding proteins and protein phosphorylation; systematics with emphasis on mono- graphic and floristic studies; tropical botany and ecology. For admission to graduate standing a student should present credits equivalent to those required for under- graduate majors in the Department, namely 24 credits in botany, a course in genetics with laboratory, mathematics through differential calculus, one year of college physics, and chemistry through organic. Those admitted without full equivalents of an undergraduate major will be re- quired to make up the deficiencies by passing appropriate coursesearly in their graduate programs. A reading knowl- edge of a foreign language and credit for basic courses in zoology and bacteriology are desirable. The program of graduate study for each student will be determined by a supervisory committee. No more than nine credits of BOT 6905 may be used to satisfy the credit requirements for a master's degree. Each student pursuing the Ph.D. degree will be required to pass a written departmental examina- tion on designated major areas of botany prior to the oral portion of the qualifying examination. There are, in addition to the facilities of the Department for graduate work, the following special resources that may be utilized in support of graduate student training and research: (1) the Florida Agricultural Experiment Stations, (2) the Marine Sciences Center on the Gulf of Mexico for studies in estuarine and marine habitats, (3) the resources of the Welaka Conservation Reserve, (4) the Center for Tropical Agriculture, which can support studies in tropi- cal and subtropical areas, (5) the Center for Aquatic Plants, and (6) the Fairchild Tropical Garden for research in the systematics, morphology and anatomy, and eco- nomic botany of tropical plants. To provide additional educational opportunities for our graduate students in the form of botanical garden research and training internship program, the Department of Bot- any has entered into an arrangement with the Marie Selby Botanical Gardens of Sarasota. Under this arrangement students spend a semester in Sarasota as part of a regular degree program; the academic portions of which are under the control of faculty members in the Department of Botany. The course of study is specifically designed by agreement among the student, the student's graduate adviser, and the Selby Gardens' Director of Research. Students register for the Selby course under BOT 6905 for nine credit hours. Interns are provided with housing on the garden grounds and a per diem to help with expenses. Interested students should communicate with the Depart- ment Chairman or Graduate Coordinator for further de- tails. BOT 5225C-Plant Anatomy (4) Prereq: BOT2011Cor3303Cor consent of instructor.
