One position will be in Biochemistry/Molecular Biology; the other position(s) will be in Ecology or Health Sciences complementing current departmental strengths and goals. Appointments are at the Assistant Professor level however, exceptionally qualified applicants may be appointed at the Associate Professor level. For all these hires, we are particularly interested in individuals who conduct research at the interfaces of ecology, biochemistry/molecular biology, and/or human health. Successful applicants will be expected to establish a vigorous, externally funded research program involving graduate and undergraduate students and to have a strong commitment to undergraduate and graduate instruction in their areas of expertise. Additional information is available at http://www.bio.mtu.edu. Applicants should submit a curriculum vitae, statements of research and teaching interests and three letters of recommendation to Chair, Faculty Search Committee, Dept. Biological Sciences, Michigan Technological University, Houghton, MI 49931; Email: biosearch@mtu.edu. Review of applications will begin Dec. 15th and continue until all positions are filled. Michigan Technological University is an equal opportunity educational institution/equal opportunity employer. At Michigan Technological University, Sustainability informs research at a university-wide scale. Candidates who are also interested in research that fits within the theme of "Sustainability" should send a separate application for one of the ten growth positions in that area as described at www.mtu.edu/sfhi."

Conserved in most eukaryotic organisms, the RNAi pathway is thought to have evolved as a form of innate immunity against viruses and also plays a major role in regulating development and genome maintenance. http://bioisolutions.blogspot.com/2007/11/rnai-discovery.html Regards Thomas From rachel.donegan from montshire.org Wed Nov 7 11:01:40 2007 From: rachel.donegan from montshire.org (Rachel Donegan) Date: Wed Nov 7 11:10:30 2007 Subject: [Plant-education] journal article Message-ID: <31104D05-FBE7-43B4-9182-79CB3FED97FD@montshire.org> Dear Dr. Hershey, I am writing to request an electronic copy of your article "The Pleasures and Pitfalls of Plant Science Activities."

I was doing a search on carrot callus culture and came upon a response you had written regarding your method of culturing carrot callus. You wrote: "I used to use the carrot callus culture medium, but have found a much simpler approach. They obtain the aseptic carrot slices as always, transfer 6 - 8 of them to a sterile Petri dish lined with moistened filter paper. Instead of bothering with callus medium, I have them moisten the filter paper with sterile distilled water. " We are trying to find a "quick and easy" way for our students to learn to culture carrot callus in our Plant Biotechnology class and find that the carrot callus cultures we obtain from Carolina are not very consistent, so they have charged me with finding a better method. I did culture carrot callus eons ago in my undergraduate work, but that was not always effective either....we actually did it on a desktop, since we didn't have hoods. Are you still using this method and find it still is working well? Have you modified it to make it more efficient? Would you mind sharing the method? In your description, you used filter paper---did you sterilize this prior to use? I would appreciate any insight you can offer and will pass on the credit and details to the professor of the class.

They actually were the eggs of a lacewing insect and were found attached to a steel pipe. The eggs are elevated on stalks so the hatchlings do not eat their unhatched siblings. It is another interesting plant myth along the lines of the Vegetable Lamb of Tartary or the Barnacle Goose tree.

The six macronutrients, needed in fairly large amounts, are nitrogen, phosphorus, potassium, calcium, magnesium and sulfur. The eight micronutrients, needed in much smaller amounts, are iron, boron, manganese, zinc, copper, molybdenum, chlorine and nickel. No natural deficiencies of chlorine and nickel have been seen because those two elements are relatively abundant in soils relative to plant needs. Potted plants are often irrigated with a fertilizer solution. Plant scientists often grow plants without soil in a Hoagland solution, or other mineral nutrient solution, to assure their plants have all the essential mineral nutrients. Here is an excellent website on plant mineral nutrition: http://www.soils.wisc.edu/~barak/soilscience326/essentl.htm The following USDA website indicates that cider vinegar contains some essential mineral nutrients, including significant amounts of potassium (730 mg/liter), phosphorus (80 mg/liter), calcium (70 mg/liter) and magnesium (50 mg/liter). Compare these numbers to those for a Hoagland Solution at the bottom. Note that the USDA tables use units of mg per 100 grams. Multiply by 10 to get standard units of mg/liter. http://www.nal.usda.gov/fnic/foodcomp/search/ The main ingredient in vinegar is acetic acid, which has an acid pH and would make water less available to the plant roots. Aloe vera is a succulent. Succulents can withstand low soil water availability better than most nonsucculents. Thus, perhaps it can tolerate the acetic acid better than many plants. Soil pH has a major effect on the availability of several mineral nutrients to plant roots. Thus, vinegar changing the soil pH might affect the amount of mineral nutrients available to the roots. See the soil pH nutrient availability graph in the following webpage: http://www.extension.umn.edu/distribution/horticulture/components/1731-03.html Milk has too high a salt (sodium chloride) concentation for irrigation of most plants. The higher the concentration of salts and other dissolved substances in the soil solution, the more difficult it is for plant roots to absorb water. In addition, the proteins, sugars and fats in milk provide an energy source for microbe growth. Microbes can produce waste products that harm plant roots or compete with plant roots for mineral nutrients. Check the soil of the milk-irrigated plant for bad odors, a sign of toxic microbial waste products. Based on the label, Hershey (2001) calculated that skim milk contained 520 mg/liter sodium, a very high level for plant irrigation water. If you can get an electrical conductivity (EC) meter, you can easily compare the EC of your three solutions to get an idea of how good they are for plant irrigation (Hershey and Sand 1993). The higher the EC, the worse the water is for plant irrigation (Hershey 1993). Hershey and Sand (1993) reported that 1% milk had an EC of 5.2 dS/m. Excellent irrigation water has an EC below 0.25 dS/m. Milk does contain very high concentrations of many of the essential nutrients for plants, especially calcium, magnesium, phosphorus, zinc and potassium. Check the USDA website mentioned earlier and compare the levels in milk to the Hoagland solution. Important questions in this experiment are the following: 1. The chemical and physical properties of the soil. Was it field soil or potting soil? Did it contain any starter fertilizer? Field soils in pots often give very poor plant growth because of their poor physical properties (Hershey 1990a). 2. The chemical composition of the tap water used as the control. Did the tap water provide significant amounts of any essential mineral nutrients, such as calcium, potassium and magnesium? Your water company can provide a chemical analysis of the tap water. 3. Was any fertilizer added? If so, what type and amount? 4. What effect did the vinegar have on the soil pH compared to the control? 5. Which is cheaper per liter, a fertilizer solution designed for irrigating potted plants, such as Miracle-Gro, or milk or vinegar (Hershey 1990b)? Irrigating plants with human beverages, such as soda, milk, tea, coffee, fruit juice, etc., is a common student project but contradicts basic biological facts that photosynthetic plants get their energy mainly from light and require only mineral nutrients and water from the soil. A better way to present such projects would be to consider what the effect on plants would be if tanker truck of milk or vinegar spilled or whether outdated milk or vinegar could be safely disposed of or recycled by using it to irrigate plants.
