From walk2iron from gmail.com Fri Aug 7 08:59:44 2009 From: walk2iron from gmail.com (Elsbeth Walker) Date: Fri Aug 7 09:02:09 2009 Subject: [Maize] postdoctoral positions, University of Massachusetts, Amherst Message-ID: Two postdoctoral positions are open in the Walker Lab in the Biology Department at the University of Massachusetts, Amherst (see http://www.bio.umass.edu/biology/faculty/ewalker.phtml for a brief overview). The first position will be to investigate the *Yellow Stripe-Like * family of genes in maize. The second, is to perform transcription profiling experiments to identify key genes for the production of the chemotherapeutic drug taxol. Each uses a combination of genetics, bioinformatics, and biochemistry. Applicants with previous plant molecular biology experience are preferred. To apply, please send the following materials to ewalker@bio.umass.edu: 1. A cover letter explaining specifically why you are interested in joining the group, what skills and knowledge you would contribute, and what you think we could offer in terms of training. In addition, please describe your career goals. 2. A CV with three or more references and their full contact information. 3. A brief proposal (a few paragraphs is enough) for a possible project in the lab. This need not be detailed, but should indicate that you have read enough of the literature to be sincerely interested in some aspect of our research, and that you can think independently and creatively about your work. This can be part of the cover letter. -- Elsbeth L Walker Director, Plant Biology Graduate Program Associate Professor, Biology UMass, Amherst Amherst, MA 01003 413 545-0861 (voice) 413 545-3243 (fax) From kv35 from cornell.edu Thu Aug 27 07:48:20 2009 From: kv35 from cornell.edu (Klaas van Wijk) Date: Thu Aug 27 14:47:11 2009 Subject: [Maize] Postdoctoral Position for a Plant Biochemist in Systems biology of Maize/Rice C3-C4 leaf development and cell differentiation Message-ID: <6.2.1.2.2.20090827084611.031ad328@postoffice6.mail.cornell.edu> Postdoctoral Position in Systems biology of Maize/Rice C3-C4 leaf development and cell differentiation van Wijk lab, Cornell University, Ithaca, NY, USA [1]http://cbsu.tc.cornell.edu/vanwijk/ A postdoctoral position for a Plant Biochemist is available in the van Wijk lab to contribute to a collaborative project sponsored by the NSF-Genome program. This project concerns a cell-type specific comparative analysis of C3 and C4 leaf development in Rice, Sorghum and Maize. In leaves of such C4 grasses photosynthetic activities are partitioned between two morphologically and biochemically distinct bundle sheath (BS) and mesophyll (M) cells. The overall objectives are to compare the quantitative and qualitative patterns of transcripts, proteins, metabolic activities and anatomy at discrete stages and in specific cell types in rice (C3), maize and sorghum (C4), and to develop a model of the regulatory networks governing C4 anatomy and function. These experimental datasets will be linked by new informatics tools for comparative transcriptional and proteome analysis, to provide the foundation for a systems biology approach to understanding C4 biology. The responsibilities of the postdoc include isolation of specific subsets of leaf proteomes (e.g. Bundle strands) for proteome analysis, as well as biological interpretation of large scale proteome (and other) datasets. In particular, a strong effort is needed on extracting biological conclusions and hypotheses from these large scale datasets. Experience in plant protein biochemistry and a strong interest in plant metabolism and systems biology is required. The postdoc will work closely together with other team members, including mass spectrometry specialists and bioinformaticians. Salary will be commensurate with experience with generous employee benefits according the Cornell Human Resource Office. Review of applications will begin immediately, and continue until the position is filled.
