Course Objectives: Botany 780 is a course intended to provide a detailed overview of
metabolic processes in plants, with attention given to the continual metabolic
adjustments that occur in plants according to the environmental conditions to
which they are exposed. The focus will
be on carbohydrate and lipid metabolism under normal conditions and how
metabolism changes when plants are exposed to various stresses. An additional goal is that lecture topics
serve the individual interests of the students, where attention will be given
to selected topics and presented within the context of plant metabolism.
Format:
The course will consist of two 75-min lectures each week. Students are encouraged to offer questions
or comments at any time during the lecture.
During an initial organizational meeting, students will have an
opportunity to discuss their research and other interests and class time will
be allotted to address student-selected topics, ideally as they relate to core
topics (listed below). Two class
periods will be reserved for a student-centered activity in which students will
design a crop plant with a prescribed phenotype. The product of this exercise will be a short group paper. Students will also be responsible for
selecting a topic within the context of plant metabolism and for delivering a
30 minute presentation at assigned dates at the end of the semester.
Lecture Topics:
Photosynthesis Ch. 12
Carbohydrate Metabolism Ch. 13
Respiration & Photorespiration Ch. 14
Lipid Metabolism Ch. 10
Secondary Metabolism Ch. 24
Biotic Stresses Ch. 21
Pathogens, some insects
Abiotic Stresses Ch. 22
Cold, light, water
Gene Expression & Signal Transduction
Protein Synthesis & Protein Sorting
Cell Cycle / Tissue Growth
Senescence
Nitrogen Fixation
Nitrogen Assimilation / Amino Acids
Mineral Nutrient Uptake and Utilization
Additional Stresses
Pollutants, heat, salt, more insects
Other topics
Grading: There will be three exams during the semester that will cover the
topics presented in lecture. Exams will
be predominantly of an essay and short answer format and will be worth 100
points each. The group paper will be
worth 50 points (all students within each group receiving the same score) and
presentations will be 50 points. Grades
will be assigned according to the standard grading scale:
> 90 = A, 80 - 89.9 = B,
70 - 79.9 = C, 60 - 69.9 = D, < 60 = F.
Special Needs:
Any students who need special accommodations for learning or who have
special needs are invited to share these concerns and requests with the
instructor as soon as possible.
Academic Responsibility: All work in this course must be completed in
a manner consistent with NDSU University Senate Policy, section 335: Code of Academic Responsibility and Conduct
(http://www.ndsu.nodak.edu/policy/335.htm).
