COURSE SYLLABUS SEEDS OF CHANGE: THE BIOLOGY AND CULTURE OF PLANT-PEOPLE INTERACTIONS "History celebrates the battlefields whereon we meet our death, but scorns to speak of the plowed fields whereby we thrive; it knows the names of the King's bastards, but cannot tell us the origin of wheat. That is the way of human folly" Jean Henri Fabre Instructor: Dr. Hector E. Flores, PhD (Yale 1983); [email protected]; 585-260-4962 Rationale Human civilization and life on earth are impossible to conceive without plants. Through photosynthesis and oxygen production, plants are the major producers of biomass and constitute the base of the food pyramid. Plants also have evolved an astounding diversity in form, size, shape, color, smell and chemical structures. This structural, nutritional and chemical flexibility has been put to innumerable uses by people, from the hunter gatherers to the scientists in search of a cure for AIDS. Plants are at the core of our everyday necessities (food, clothing, shelter, medicines, beverages), simple pleasures (flowers, fragrances) and pervasive problems (energy supply, drug addiction, famine). Plants have affected civilization in dramatic ways in the past, for example in the spectacular changes in diet and the increased population growth catalyzed by the Columbian Exchange. We expect that plants will continue to affect people in the future through an increasingly complex interplay between new technologies such as genetic engineering, the pressure on natural resources, and the search for new crops, medicines and biomaterials. The aforementioned examples justify including a course on the uses of plants in a graduate/undergraduate curriculum that stresses interdisciplinarity, diversity, and multiculturalism. Seeds of Change is a 3 credit course offered at the 4000/5000 level, and is designed to provide an in-depth integrated overview of the biology, chemistry and culture of plants, as well as a long term perspective on their present and future uses. Prerequisite This is a reading-intensive and discussion-oriented course which assumes basic knowledge of biology/botany and/or chemistry. Students with little background in any of these areas are strongly encouraged to consult introductory textbooks in order to become familiar with the basic concepts and vocabulary. The following books are recommended: Buchanan, B.B., W. Gruissem, and R.L. Jones. 2000. Biochemistry and Molecular Biology of Plants. American Society of Plant Physiologists, Rockville, Maryland. Capon, B. 1990. Botany for Gardeners: An Introduction and Guide. Timber Press, Portland, Oregon. Stern, K.R. 1988. Introductory Plant Biology. 4th Ed., Wm. C. Brown, Dubuque, IA. Snyder, C.H. 1995. The Extraordinary Chemistry of Ordinary Things. 2nd Ed., John Wiley & Sons, New York. Zomlefer, W.B. 1994. Guide to Flowering Plant Families. University of North Carolina Press, Chapel Hill. Course Structure This course is intended to go beyond the lecture only format. Conventional lectures will be complemented with discussions, use of fresh plant material, demonstrations, group projects, and "field" assignments. After a basic treatment of the botanical concepts necessary to follow the subject, we will discuss the major modes of plant use, from food and medicine gathering to the origins of agriculture, and how the latter evolved. Second, we will study the Columbian Exchange as an example of how plants have shaped our diets, clothing and addictions in the last five hundred years. Third, we will use potatoes, sugar cane and cotton as case studies of how the unique biological features of these crops have affected their large scale worldwide cultivation, and the social and economic effects of such practices. The rest of the course will be organized along the same lines, maintaining the emphasis on interdisciplinary discussions. It is hoped that this approach will allow the student to start perceiving useful plants as what they effectively are, Seeds of Change, affecting diets, agricultural patterns, health and leisure, but in turn also being influenced by population pressures, other crops, and the new biotechnologies. Class Participation The success of this course depends on student participation in the lectures and class discussions. The variety of majors hopefully represented in the class provides a unique opportunity for students to offer valuable, diverse, and complementary input during the class discussions. Therefore, the students are strongly encouraged to ask questions, participate in discussions, and help each other in the various activities. A list-serve site will be set up to encourage and facilitate additional discussion outside the classroom. This site can be used to send messages to the class members, and ask questions, share insights, debate problems, and plan individual/group activities or assignments (see below). Journal Paper Report Because of the range of subjects covered in the class, it is difficult to conduct an in-depth critical analysis of every single topic. In order to provide hands-on experience with the analysis of data and the process leading to conclusions that eventually find their way into textbooks and reviews, each student will be required to do a critical review of refereed journal articles throughout the class. Examples of journals with appropriate articles are American Journal of Botany, Economic Botany, Journal of Ethnobiology, Journal of Ethnopharmacology, Plant Journal, Plant Cell, etc. In addition to providing a detailed criticism of the assumptions underlying the paper’s rationale, results and discussion, the student will have to provide a complementary perspective for future, integrative work. Class Project One of the goals of courses such as this one is to encourage creativity and originality from the students. To this end, at the end of the semester, each student will have to deliver, as an individual of as part of a group (the latter is strongly encouraged), a class presentation on any subject related to the interactions between plants and people. Conventional presentations are strongly discouraged. Students are encouraged to use the full range of skills they have (individually and collectively, i.e., art, music, writing, handcrafts, computer skills, etc.), to address the topic of their choice. For example, a presentation on the evolution of bread could based on baking and tasting a variety of homemade products, the biology and culture of tomato could be presented as a play, a poem or series thereof, etc., etc. Examples of innovative angles to these class projects may be the relationship between myths, plants and women, the use of plants as medicine by animals, cultural parallelism in the uses of plants, biochemical changes during cooking/food processing, etc. The project must be based on solid research and facts, the creative synthesis and integration of which will be reflected in the project’s originality. The most important thing to consider for this type of project is planning and brainstorming in advance. The instructor will work with the students to provide advice as to project choice and approach, but this is first and foremost a student-driven activity. The presentations will be scheduled for the end of the course, and some of them, as appropriate, may be included in the last activity of the semester, the Seeds of Change Potluck (see below). Class Assignments and Special Activities Class Assignments Throughout the course students will be asked to visit the local supermarkets, health food and ethnic food stores, and local pharmacies, in order to do “homework” related to an upcoming class topic. For example, for the lecture/discussion on fruit crops the students may have to make an inventory of the fruits available at that particular time of the year, and to determine their "geography" (where do the fruits come from?) and how that relates to their place of origin. For the discussion on medicinal plants, the students may have to go to pharmacies, supermarkets, health food stores, etc., and research the variety of health-related formulations which include plant-derived products. Short reports may be required for some of these exercises. Field Trip We will have at least one field trip in early Spring to observe useful wild plants at a suitable place nearby. Attendance to the field trip is required of all students. Demonstrations The lectures and discussions will be complemented by simple exercises and demonstrations. For example, the lecture on beverages may be followed by a tasting of teas and herbal infusions. The lecture on perfumes may be followed by simple extractions of essential oils from various sources (rose petals, geraniums, various herbs, etc.). The discussions on spices and fruits will involve tastings and dissections of the material brought by students and instructors. Various dishes will be tasted throughout the class, starting with the salad “deconstruction” exercise. Seeds of Change Potluck A potluck dinner will be scheduled for the end of the semester at the instructor's home. The different courses will be jointly planned by the instructor and students and will be designed to reflect the widest possible diversity of plant foods available in the area. Students are strongly encouraged to plan and prepare their dishes by dividing into small groups. This activity is intended to be fun and promote collegiality, in addition to providing yet another venue to learn more about plants/people interactions. Exams and Grading There will be two examinations throughout the semester. The first exam will be scheduled before Spring break and will cover one third of the course material. The second exam will emphasize material covered in the second third, and will be scheduled for the first half of April. The examinations will be a combination of short answer and essay questions; the latter will emphasize critical thinking and integration of the facts and concepts discussed in class. Take-home exams are also an option. There will be no final exam, in lieu of which students are required to develop an original project (see above). The final grade will be assigned on the following basis: First Exam 35% Second Exam 35% Class project 20% Class participation, written assignment 10% Textbook and Assigned Reading As mentioned above, this will be a reading-intensive course. The textbook chosen for this course is Economic Botany, Plants in Our World , 3rd Edition (2001), by Beryl Brintnall Simpson and Mary Conner-Ogorzaly (McGraw-Hill, New York) and is available at the Penn State Bookstore. The assigned readings from the textbook (see class schedule) will provide introductory botanical concepts and descriptions of useful plants according to well established categories (fruits, grains, spices, vegetable oils, medicines, etc.). Because the course is designed to provide an interdisciplinary perspective of useful plants, the textbook assignments will be complemented with readings from a variety of sources. The strategy for handling the assigned reading will be discussed during the first meeting. I also highly recommend Plants, People, and Culture, by Michael Balick and Paul Cox, as a “textbook” to complement Simpson’s. It is full of fascinating stories and perhaps does a better job of integrating biology, chemistry and culture. Reading List Some material for this class is available at the Library. Much of the material listed below is in my personal collection, which will be made available to students on an honors basis. Specific reading assignments from some of these books and from journal articles are listed in the course schedule. Sets of the assigned readings will be available for copying. This reading list can be also used as a reference source in the preparation of term papers and for class assignments. Allen, B. 1995. Food, an Oxford Anthology.
