    Description: The origin and evolution of photosynthesis have long remained enigmatic due to a lack of sequence information of photosynthesis genes across the entire photosynthetic domain. To probe early evolutionary history of photosynthesis, we obtained new sequence information of a number of photosynthesis genes from the green sulfur bacterium Chlorobium tepidum and the green nonsulfur bacterium Chloroflexus aurantiacus. A total of 31 open reading frames that encode enzymes involved in bacteriochlorophyll/porphyrin biosynthesis, carotenoid biosynthesis, and photosynthetic electron transfer were identified in about 100 kilobase pairs of genomic sequence. Phylogenetic analyses of multiple magnesium-tetrapyrrole biosynthesis genes using a combination of distance, maximum parsimony, and maximum likelihood methods indicate that heliobacteria are closest to the last common ancestor of all oxygenic photosynthetic lineages and that green sulfur bacteria and green nonsulfur bacteria are each other's closest relatives. Parsimony and distance analyses further identify purple bacteria as the earliest emerging photosynthetic lineage. These results challenge previous conclusions based on 16S ribosomal RNA and Hsp60/Hsp70 analyses that green nonsulfur bacteria or heliobacteria are the earliest phototrophs. The overall consensus of our phylogenetic analysis, that bacteriochlorophyll biosynthesis evolved before chlorophyll biosynthesis, also argues against the long-held Granick hypothesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xiong, J -- Fischer, W M -- Inoue, K -- Nakahara, M -- Bauer, C E -- GM53940/GM/NIGMS NIH HHS/ -- R01 GM053940/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2000 Sep 8;289(5485):1724-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Indiana University, Bloomington, IN 47405, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10976061" target="_blank"〉PubMed〈/a〉

    Description: In humans, interferon gamma (IFN-gamma) receptor deficiency leads to a predisposition to mycobacterial infections and impairs the formation of mature granulomas. Interleukin-12 (IL-12) receptor deficiency was found in otherwise healthy individuals with mycobacterial infections. Mature granulomas were seen, surrounded by T cells and centered with epithelioid and multinucleated giant cells, yet reduced IFN-gamma concentrations were found to be secreted by activated natural killer and T cells. Thus, IL-12-dependent IFN-gamma secretion in humans seems essential in the control of mycobacterial infections, despite the formation of mature granulomas due to IL-12-independent IFN-gamma secretion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Altare, F -- Durandy, A -- Lammas, D -- Emile, J F -- Lamhamedi, S -- Le Deist, F -- Drysdale, P -- Jouanguy, E -- Doffinger, R -- Bernaudin, F -- Jeppsson, O -- Gollob, J A -- Meinl, E -- Segal, A W -- Fischer, A -- Kumararatne, D -- Casanova, J L -- New York, N.Y. -- Science. 1998 May 29;280(5368):1432-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INSERM U429, Hopital Necker-Enfants Malades, Paris 75015, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9603732" target="_blank"〉PubMed〈/a〉

    Description: Memories are thought to be due to lasting synaptic modifications in the brain. The search for memory traces has relied predominantly on determining regions that are necessary for the process. However, a more informative approach is to define the smallest sufficient set of brain structures. The rutabaga adenylyl cyclase, an enzyme that is ubiquitously expressed in the Drosophila brain and that mediates synaptic plasticity, is needed exclusively in the Kenyon cells of the mushroom bodies for a component of olfactory short-term memory. This demonstrates that synaptic plasticity in a small brain region can be sufficient for memory formation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zars, T -- Fischer, M -- Schulz, R -- Heisenberg, M -- New York, N.Y. -- Science. 2000 Apr 28;288(5466):672-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Theodor Boveri Institut fur Biowissenschaften, Lehrstuhl fur Genetik, (Biozentrum) Am Hubland, D97074, Wurzburg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10784450" target="_blank"〉PubMed〈/a〉

    Description: Dorsoventral patterning of vertebrate and Drosophila embryos requires bone morphogenetic proteins (BMPs) and antagonists of BMP activity. The Drosophila gene tolloid encodes a metalloprotease similar to BMP-1 that interacts genetically with decapentaplegic, the Drosophila homolog of vertebrate BMP-2/4. Zebrafish embryos overexpressing a zebrafish homolog of tolloid were shown to resemble loss-of-function mutations in chordino, the zebrafish homolog of the Xenopus BMP-4 antagonist Chordin. Furthermore, Chordin was degraded by COS cells expressing Tolloid. These data suggest that Tolloid antagonizes Chordin activity by proteolytically cleaving Chordin. A conserved function for zebrafish and Drosophila Tolloid during embryogenesis is proposed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blader, P -- Rastegar, S -- Fischer, N -- Strahle, U -- New York, N.Y. -- Science. 1997 Dec 12;278(5345):1937-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Genetique et de Biologie Moleculaire et Cellulaire (IGBMC), CNRS/INSERM/ULP, BP 163, 67404 Illkirch Cedex, C.U. de Strasbourg, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9395394" target="_blank"〉PubMed〈/a〉

    Description: During speech acquisition, children form quick and rough hypotheses about the meaning of a new word after only a single exposure-a process dubbed "fast mapping." Here we provide evidence that a border collie, Rico, is able to fast map. Rico knew the labels of over 200 different items. He inferred the names of novel items by exclusion learning and correctly retrieved those items right away as well as 4 weeks after the initial exposure. Fast mapping thus appears to be mediated by general learning and memory mechanisms also found in other animals and not by a language acquisition device that is special to humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaminski, Juliane -- Call, Josep -- Fischer, Julia -- New York, N.Y. -- Science. 2004 Jun 11;304(5677):1682-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Developmental and Comparative Psychology, Max-Planck Institute for Evolutionary Anthropology, Deutscher Platz 6, 04103 Leipzig, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15192233" target="_blank"〉PubMed〈/a〉
