    Trojan horse strategy in Agrobacterium transformation: abusing MAPK defense signaling (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-10-20
    Description: Nuclear import of transfer DNA (T-DNA) is a central event in Agrobacterium transformation of plant cells and is thought to occur by the hijacking of certain host cell proteins. The T-DNA-associated virulence protein VirE2 mediates this process by binding to the nuclear import machinery via the host cell factor VIP1, whose role in plants has been so far unknown. Here we show that VIP1 is a transcription factor that is a direct target of the Agrobacterium-induced mitogen-activated protein kinase (MAPK) MPK3. Upon phosphorylation by MPK3, VIP1 relocalizes from the cytoplasm to the nucleus and regulates the expression of the PR1 pathogenesis-related gene. MAPK-dependent phosphorylation of VIP1 is necessary for VIP1-mediated Agrobacterium T-DNA transfer, indicating that Agrobacterium abuses the MAPK-targeted VIP1 defense signaling pathway for nuclear delivery of the T-DNA complex as a Trojan horse.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Djamei, Armin -- Pitzschke, Andrea -- Nakagami, Hirofumi -- Rajh, Iva -- Hirt, Heribert -- New York, N.Y. -- Science. 2007 Oct 19;318(5849):453-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Molecular Biology, Max F.

    Draft genome sequence of the sexually transmitted pathogen Trichomonas vaginalis (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-01-16
    Description: We describe the genome sequence of the protist Trichomonas vaginalis, a sexually transmitted human pathogen. Repeats and transposable elements comprise about two-thirds of the approximately 160-megabase genome, reflecting a recent massive expansion of genetic material. This expansion, in conjunction with the shaping of metabolic pathways that likely transpired through lateral gene transfer from bacteria, and amplification of specific gene families implicated in pathogenesis and phagocytosis of host proteins may exemplify adaptations of the parasite during its transition to a urogenital environment. The genome sequence predicts previously unknown functions for the hydrogenosome, which support a common evolutionary origin of this unusual organelle with mitochondria.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2080659/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2080659/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carlton, Jane M -- Hirt, Robert P -- Silva, Joana C -- Delcher, Arthur L -- Schatz, Michael -- Zhao, Qi -- Wortman, Jennifer R -- Bidwell, Shelby L -- Alsmark, U Cecilia M -- Besteiro, Sebastien -- Sicheritz-Ponten, Thomas -- Noel, Christophe J -- Dacks, Joel B -- Foster, Peter G -- Simillion, Cedric -- Van de Peer, Yves -- Miranda-Saavedra, Diego -- Barton, Geoffrey J -- Westrop, Gareth D -- Muller, Sylke -- Dessi, Daniele -- Fiori, Pier Luigi -- Ren, Qinghu -- Paulsen, Ian -- Zhang, Hanbang -- Bastida-Corcuera, Felix D -- Simoes-Barbosa, Augusto -- Brown, Mark T -- Hayes, Richard D -- Mukherjee, Mandira -- Okumura, Cheryl Y -- Schneider, Rachel -- Smith, Alias J -- Vanacova, Stepanka -- Villalvazo, Maria -- Haas, Brian J -- Pertea, Mihaela -- Feldblyum, Tamara V -- Utterback, Terry R -- Shu, Chung-Li -- Osoegawa, Kazutoyo -- de Jong, Pieter J -- Hrdy, Ivan -- Horvathova, Lenka -- Zubacova, Zuzana -- Dolezal, Pavel -- Malik, Shehre-Banoo -- Logsdon, John M Jr -- Henze, Katrin -- Gupta, Arti -- Wang, Ching C -- Dunne, Rebecca L -- Upcroft, Jacqueline A -- Upcroft, Peter -- White, Owen -- Salzberg, Steven L -- Tang, Petrus -- Chiu, Cheng-Hsun -- Lee, Ying-Shiung -- Embley, T Martin -- Coombs, Graham H -- Mottram, Jeremy C -- Tachezy, Jan -- Fraser-Liggett, Claire M -- Johnson, Patricia J -- 072031/Wellcome Trust/United Kingdom -- G0000508/Medical Research Council/United Kingdom -- G0000508(56841)/Medical Research Council/United Kingdom -- G9722968/Medical Research Council/United Kingdom -- G9722968(65078)/Medical Research Council/United Kingdom -- R01 LM006845/LM/NLM NIH HHS/ -- R01 LM006845-08/LM/NLM NIH HHS/ -- R01 LM007938/LM/NLM NIH HHS/ -- R01 LM007938-04/LM/NLM NIH HHS/ -- U01 AI050913/AI/NIAID NIH HHS/ -- U01 AI050913-01A1/AI/NIAID NIH HHS/ -- U01 AI050913-02/AI/NIAID NIH HHS/ -- UO1 AI50913-01/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2007 Jan 12;315(5809):207-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Genomic Research, 9712 Medical Research Drive, Rockville, MD 20850, USA. jane.carlton@med.nyu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17218520" target="_blank"〉PubMed〈/a〉
