    Control of cell fate by a deubiquitinating enzyme encoded by the fat facets gene (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-12-15
    Description: Ubiquitin is a highly conserved polypeptide found in all eukaryotes. The major function of ubiquitin is to target proteins for complete or partial degradation by a multisubunit protein complex called the proteasome. Here, the Drosophila fat facets gene, which is required for the appropriate determination of particular cells in the fly eye, was shown to encode a ubiquitin-specific protease (Ubp), an enzyme that cleaves ubiquitin from ubiquitin-protein conjugates. The Fat facets protein (FAF) acts as a regulatory Ubp that prevents degradation of its substrate by the proteasome. Flies bearing fat facets gene mutations were used to show that a Ubp is cell type--and substrate-specific and a regulator of cell fate decisions in a multicellular organism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huang, Y -- Baker, R T -- Fischer-Vize, J A -- New York, N.Y. -- Science. 1995 Dec 15;270(5243):1828-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Texas, Austin 78712, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8525378" target="_blank"〉PubMed〈/a〉

    Molecular genetics of plant disease resistance (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-05-05
    Description: Plant breeders have used disease resistance genes (R genes) to control plant disease since the turn of the century. Molecular cloning of R genes that enable plants to resist a diverse range of pathogens has revealed that the proteins encoded by these genes have several features in common. These findings suggest that plants may have evolved common signal transduction mechanisms for the expression of resistance to a wide range of unrelated pathogens. Characterization of the molecular signals involved in pathogen recognition and of the molecular events that specify the expression of resistance may lead to novel strategies for plant disease control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Staskawicz, B J -- Ausubel, F M -- Baker, B J -- Ellis, J G -- Jones, J D -- New York, N.Y. -- Science. 1995 May 5;268(5211):661-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Biology, University of California, Berkeley 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7732374" target="_blank"〉PubMed〈/a〉

    Selective trafficking of KNOTTED1 homeodomain protein and its mRNA through plasmodesmata (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-12-22
    Description: Plasmodesmata are intercellular organelles in plants that establish cytoplasmic continuity between neighboring cells. Microinjection studies showed that plasmodesmata facilitate the cell-to-cell transport of a plant-encoded transcription factor, KNOTTED1 (KN1). KN1 can also mediate the selective plasmodesmal trafficking of kn1 sense RNA. The emerging picture of plant development suggests that cell fate is determined at least in part by supracellular controls responding to cellular position as well as lineage. One of the mechanisms that enables the necessary intercellular communication appears to involve transfer of informational molecules (proteins and RNA) through plasmodesmata.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lucas, W J -- Bouche-Pillon, S -- Jackson, D P -- Nguyen, L -- Baker, L -- Ding, B -- Hake, S -- New York, N.Y. -- Science. 1995 Dec 22;270(5244):1980-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Plant Biology, University of California, Davis 95616, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8533088" target="_blank"〉PubMed〈/a〉
