student's interest and are drawn from over 50 electives
taught by departments in the Colleges of Agriculture, Medi-
cine, and Liberal Arts and Sciences.
 In order to provide exposure to a variety of faculty and
experimental systems, new students are encouraged to
rotate among three laboratories during the first six months
of enrollment before selection of a dissertation research
area and supervisory committee. For additional informa-
tion, write to the Graduate Coordinator, Plant Molecular
and Cellular Biology, 3103 McCarty Hall.

 The Department of Plant Pathology offers graduate stud-
ies leading to the Master of Agriculture, Master of Science,
and Doctor of Philosophy degrees. A superior studentwith
a baccalaureate degree may begin graduate study toward a
higher degree in the basic areas of plant pathology. These
areas include molecular and biochemical aspects of host-
pathogen systems, biological control of pathogens and
weeds, epidemiology, etiology, genetics of host-pathogen
systems, soil microbiology, and pathogen taxonomy. In
Florida, the diversity of cropping sequences, coupled with
an environment ideal for plant disease development, is
unexcelled and offers the student opportunities to study
diseases of unique crops as well as diseases of crops of
national and international importance. Intimate knowledge
can be gained of diseases of field, forage, fruit, ornamental,
pasture, range, turf, and vegetable crops in temperate,
subtropical, and tropical environments. Students who an-
ticipate study in plant pathology at the University of Florida
should include in their undergraduate programs training in
botany (anatomy, cytology, physiology, systematics), chem-
Istry (through biochemistry), genetics, microbiology, phys-
ics, zoology, and mathematics.
 The Department of Entomology and Nematology offers
courses in nematology.
