Assignment:
Research one aspect of molecular biology or genetics as it pertains to plants and gave 20 minutes oral presentation in class describing this area of research. Use the format of questions below to help guide you in your research for the presentation. I expect you to use at least one review of that field and 3-4 research papers. A questionnaire will be handed out to the students in class, who will evaluate your oral presentation. This questionnaire is listed below, which will also help you in preparing for the oral presentation.Examples of topics:I will grade your presentation based on both my own evaluation as well as the student's evaluations. The grade (100 points) will count for one-third of the total grade. I will be glad to help you with choice of topics, literature research strategies, and the organization of the presentation.
The following is the tentative schedule of the presentations. 20 minutes presentaion by each person followed by 5-minutes questioning from the audience. Please let me know if there is any problem with the schedule. I encourage everyone of you to choose a different topic, so the audience will benefit from hearing a wide range of researches. I will need a formal title by May 1st.May 4, 2004
1. Kuang-Yu Chen, Phytomediation
2. Banu Saritas-yildirim, Post Transcriptional Gene Silencing
3. Katherine Sorber, title to be determined
May 6, 2004
1. Harin Kanani, Metabolic profiling in plant research
2. Mike Tatusov, Medicinal Plants
3. Ping Xue, Engineering Better Food for a Better Future
May 11, 2004
1. Jonathan Helfgott, BT crops.
Topics may focus on certain aspects of plants that have practical applications (i.e. applied biotechnology), such as:Questions to be addressed in presentation:
-improvement of food quality by changing seed storage protein
-engineering tomato fruit ripening or softening (e.g. the Flavr Savr (TM) tomato, Endless Summer (TM) tomato)
-production of medicinal or industrial proteins in plants (e.g. vaccine production, antibody production, phytase)
-modification of plants in production of secondary metabolites for insect or herbivor protection
-altering the production of secondary metabolites (e.g. alkaloids) in plants for foods or medicines (e.g. decaffinated coffee, scopalamine)
-construction of herbicide-resistant plants
-engineering insect resistance, Bt toxin
-production of plastics in plants
-population genetics in conservation of rare speciesTopics may focus on basic aspects of plant biology, such as:
-regulation of flowering by light (circadian rhythm, daylength control of flowering, phototropism)
-control of motion (e.g. venus fly-trap, tendril or stem movements in vines)
- sucrose transport in plants
- heat shock proteins
- adaption to cold (e.g. winter hardening)
- genome mapping in Arabidopsis
- regulation of plant growth by hormones (e.g. auxins, cytokinins, abscisic acid)
-flower development
-DNA markers in determining plant relationships (Molecular Systematics)
-PCR amplification of fossil or mumified specimein DNA (e.g. pre-columbian maize)
Questionnaire for evaluating the presentations:
Use 1(least impressive) to 5 (most
impressive) in answering following questions:
1. How is the general impression of the presentaion?
2. How interesting is the topic?
3. Is the presentation clear in conveying the research question and
approach, etc?
4. Is the presentation well organized?
5. Is the presenter easy to understand?
6. Is the quality of the powerpoint/overhead good for visualization?
7. Is the background information and the review thorough?
8. Is the presentaion hypothesis-driven?
9. How well is the presenter at answering audience's questions?
Literature research:
To choose topics of interest and to get an overview of an area, it is
best to look through short review articles. The following journals are
found in McKeldin library unless otherwise noted. Current issues are
found on
the first floor reading room arranged alphabetically, older issues are
in
the stacks under the call number. In the chemistry library, older
issues
are arranged alphabetically on the lower two floors.
