Professor Gerd Jürgens (also spelt Juergens) (born 1949) is a plant developmental biologist currently(as of end 2010) holding the posts of Director of the Cell Biology Department at the Max Planck Institute for Developmental Biology〔http://www.eb.tuebingen.mpg.de/departments/5-cell-biology〕 and Head of the Center for Plant Molecular Biology(ZMBP)〔http://siren.punkt-international.eu/index.php?id=53〕 at the Eberhard-Karls Universität Tübingen. He has published extensively in leading journals, including eight papers in the journal Nature as well as various articles in the journals Cell, Science, Journal of Cell Biology and The Plant Journal.〔http://www.mnf.uni-tuebingen.de/fachbereiche/zentren/zmbp/developmental-genetics/juergens/publications.html〕 During his postdoctoral years in the 1980s he worked with Nobel prize winners Christiane Nüsslein-Volhard and Eric Wieschaus at the European Molecular Biology Laboratory (EMBL) in Heidelberg on the topic of ''Drosophila melanogaster'' embryogenesis.〔http://www.bio-pro.de/standort/03483/index.html?lang=en&artikelid=/artikel/03651/index.html〕〔http://nobelprize.org/nobel_prizes/medicine/laureates/1995/nusslein-volhard-autobio.html〕 At the age of 37 he made the switch from animal to plant research and became one of the first researchers to work on what was later to become the model plant organism: ''Arabidopsis thaliana''.〔http://www.bio-pro.de/standort/03483/index.html?lang=en&artikelid=/artikel/03651/index.html〕 He was responsible for pioneering research in the genetic dissection of plant embryogenesis. Using the genetically-tractable plant ''Arabidopsis thaliana'' he conducted the first forward genetic screen (using mutagenesis with 0.3% ethyl methane sulfonate(EMS)) looking for embryonic defects.〔Mayer, U., Torres Ruiz, R. A,, Berleth, T., MisCra, S. and Jürgens, G. 1991. Mutations affecting body organization in the ''Arabidopsis thaliana'' embryo. Nature 353:402-407.〕 His laboratory discovered and characterized the protein KNOLLE, which is required for cytokinesis and was the first protein known to exclusively target the cell plate in plant cells.〔Lukowitz, W., Mayer, U., Jürgens, G. (1996). Cytokinesis in the Arabidopsis embryo involves the syntaxin-related KNOLLE gene product. Cell 84, 61-71.〕〔Lauber, M.H., Waizenegger, I., Steinmann, T., Schwarz, H., Mayer, U., Hwang, I., Lukowitz, W., Jürgens, G. (1997). The Arabidopsis KNOLLE protein is a cytokinesis-specific syntaxin. J. Cell Biol. 139, 1485-1493.〕 Prof Gerd Jürgens also worked extensively on the ARF-GEF GNOM.〔Geldner, N., Anders, N., Wolters, H., Keicher, J., Kornberger, W., Muller, P., Delbarre, A., Ueda, T., Nakano, A., Jürgens, G. (2003). The Arabidopsis GNOM ARF-GEF mediates endosomal recycling, auxin transport, and auxin-dependent plant growth. Cell 112(2), 219-30.〕〔Anders, N., Nielsen, M., Keicher, J., Stierhof, Y.D., Furutani, M., Tasaka, M., Skriver, K., Jürgens, G. (2008). Membrane association of the Arabidopsis ARF exchange factor GNOM involves interaction of conserved domains. Plant Cell 20(1):142-51.〕 Both ''knolle'' and ''gnom'' were first discovered in his embryonic mutant screens.〔Mayer, U., Torres Ruiz, R. A,, Berleth, T., MisCra, S. and Jurgens, G. 1991. Mutations affecting body organization in the ''Arabidopsis thaliana'' embryo. Nature 353:402-407.〕 == Prizes and Awards == Prof Gerd Jürgens won the Gottfried Wilhelm Leibniz Prize(the highest research prize in Germany) in 1995. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gerd Jürgens」の詳細全文を読む スポンサード リンク
