83-311 Crop Physiology F(3-3)

Physiological and biochemical principles related to production by crop canopies. Carbon fixation, leaf area, light interception, assimilate distribution, water relations and nutrient utilization are used to develop solutions to problems of crop yield and quality. Growth and development in response to cultural innovations including the use of growth regulators are also considered. Departments of Crop Science and Horticultural Science.

Prerequisites: 17-230.
Course Profile

83-375 Plant Tissue Culture F(2-3)

An examination and discussion of the principles, protocols and utilization of plant cell tissue culture systems. In vitro propagation and regeneration, mutagenesis and selection, secondary metabolite elicitation and cell transformation techniques including protoplast fusion, direct DNA uptake and plant bacterial co-cultivation will be emphasized. Departments of Crop Science and Horticultural Science.

Prerequisites: 40-202.
Course Profile

83-400 Molecular and Cellular Aspects of Plant-Microbe Interactions F(3-0)

Examination of molecular and cellular aspects of the interaction between plants and microorganisms such as mycorrhizae, pathogenic fungi, Agrobacterium and plant viruses. Topics include microbial virulence, signalling, gene expression, and disease resistance in plants. Departments of Botany and Environmental biology.

Prerequisites: 17-115, 65-100. 40-200 and 40-202 are recommended.
Course Profile

83-403 Plant Cell Biology W(3-0)

An examination and discussion of structure-function relationships at the subcellular level during plant growth and development. Organelles and their roles in biosynthetic, bioenergetic and physiological processes that are unique to plants will be emphasized. Departments of Botany and Crop Science. (Offered in odd-numbered years.)

Prerequisites: (15-220 or 15-221), 17-230.
Course Profile

83-410 Soil Plant Relationships W(3-0)

Root growth as affected by soil properties; soil plant water relations; soil aeration; absorption, translocation and function of nutrients in plants; ion transport to roots; rhizosphere effects; application of concepts to crop production. Departments of Land Resource Science and Horticultural Science.

Prerequisites: 17-230, (01-1101/2 or 01-2301/2 or 87-201 or equivalent.)
Course Profile

83-415 Molecular and Cellular Aspects of Plant Development W(3-0)

An examination of the molecular and cellular processes that underlie cellular differentiation and organ formation in plants. The roles of homeotic genes, gene regulation, cell polarity, morphogens and environmental effects in development will be discussed. Subjects will be introduced by a lecture and examined in detail in discussions of pertinent research papers. (Offered in even-numbered years.)

Prerequisites: 17-230, 17-240.
Course Profile

83-453 Environmental Pollution Stresses on Plants W(3-0)

The study of environmental pollution effects on plants in natural and agricultural settings. Included are gaseous, liquid and particulate atmospheric pollutants and radiation stresses.

Prerequisites: 15-201, 17-230.
Exclusions: 34-453.
Course Profile

83-460 Plant Environment Interaction and Stress Physiology W(3-2)

The effects of environmental stresses on plant growth, development and yield, and the physiological and physical mechanisms used by plants to tolerate these stresses are discussed with emphasis on low temperature, wind and water stresses. Fundamental plant processes including membrane transport, cell elongation, stomatal control, osmotic adjustment, sap flow, photosynthesis and the role of growth regulators are discussed in relation to their response to environmental stress. Departments of Crop Science and Horticultural Science.

Prerequisites: 17-230.
Course Profile

83-475 Genetic Engineering of Plants W(3-3)

An examination and discussion of the principles, protocols and applications of molecular biology and transformation technology to the genetic improvements of plants. Departments of Crop Science and Horticultural Science.
