From d.a.walker from sheffield.ac.uk Tue Feb 26 03:45:12 2008 From: d.a.walker from sheffield.ac.uk (David Walker) Date: Tue Feb 26 06:30:34 2008 Subject: [Plant-education] Starch Picture Message-ID: Recently I was attempting to sort out the accumulated rubbish in my office in the way that you do when you come to feel that, if you don?t drink your best wine soon, you might never get the chance. By chance I came across a photograph of an ancient (ca 1980) starch picture that posed a question to students who got to see it. The picture was formed in starch in a ?Geranium? (i.e Pelargonium) leaf by illuminating through a negative in a slide projector. The negative itself comprised a Beardsley print on which was superimposed the question. I couldn?t bring myself to bin it without sharing it, so for anyone who is interested, it can now be downloaded (and used) from http://www.oxygraphics.plus.com//Beardsley.gif David >From David Alan Walker, FRS; Emeritus Professor of Photosynthesis, University of Sheffield, UK. http://www.oxygraphics.co.uk/ http://www.peerlesspublications.co.uk/ From shigbie from sjc.edu Tue Feb 26 09:23:43 2008 From: shigbie from sjc.edu (Higbie, Sarah) Date: Tue Feb 26 09:31:33 2008 Subject: [Plant-education] extraction of mtDNA Message-ID: <954A5413620E074797298540927621C5117F30D1@sjcexchange.SJC.EDU> Hello All, I am wondering if anyone has any tips for isolating quality mitochondrial DNA from leaves. We have tried a few protocols (Triboush et al. 1998. Plant Mol Biol Rep 16: 183-189; Dellaporta et al. 1983. Plant Mol Biol rep 1:19-21; Scotti et al. 2001. Plant Mol Biol Rep 19:67a-67h) with limited success. We will be using the mtDNA with PCR. Any help is greatly appreciated.

Message-ID: Hello, I am an Art Center College of Design student and I am working on an info graphics piece that is similar to what you posted online. I work in Interactive design and am interested in a software driven device that can visually identify plants by leaf shape. Have you made any progress? If so, is there any additional info you can email me. I am very interested in this subject. I would be willing to exchange ideas with you if you are interested. My name is Ryan and I am in Southern California. Please let me know soon, so I can implement it into my project over next month. Thanks. __ Ryan D'Orazi AIGA/ Art Center Student Group dorazi@artcenter.edu From jfh30 from cam.ac.uk Wed Feb 27 10:16:58 2008 From: jfh30 from cam.ac.uk (John Hewitson) Date: Wed Feb 27 10:18:51 2008 Subject: [Plant-education] Re: Visual Plant Recognition Scanning Programs - Anyone have one? In-Reply-To: References: Message-ID: http://www-saps.plantsci.cam.ac.uk/trees/index.htm works on leaf shape for common British trees and shrubs - it also works for winter twigs without leaves. Does, however, need a person to look at the leaves and decide which category they fit into. Dr. John F.
