    Host-to-parasite gene transfer in flowering plants: phylogenetic evidence from Malpighiales (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-07-17
    Description: Horizontal gene transfer (HGT) between sexually unrelated species has recently been documented for higher plants, but mechanistic explanations for HGTs have remained speculative. We show that a parasitic relationship may facilitate HGT between flowering plants. The endophytic parasites Rafflesiaceae are placed in the diverse order Malpighiales. Our multigene phylogenetic analyses of Malpighiales show that mitochondrial (matR) and nuclear loci (18S ribosomal DNA and PHYC) place Rafflesiaceae in Malpighiales, perhaps near Ochnaceae/Clusiaceae. Mitochondrial nad1B-C, however, groups them within Vitaceae, near their obligate host Tetrastigma. These discordant phylogenetic hypotheses strongly suggest that part of the mitochondrial genome in Rafflesiaceae was acquired via HGT from their hosts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis, Charles C -- Wurdack, Kenneth J -- New York, N.Y. -- Science. 2004 Jul 30;305(5684):676-8.

    The genome of the diatom Thalassiosira pseudonana: ecology, evolution, and metabolism (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-10-02
    Description: Diatoms are unicellular algae with plastids acquired by secondary endosymbiosis. They are responsible for approximately 20% of global carbon fixation. We report the 34 million-base pair draft nuclear genome of the marine diatom Thalassiosira pseudonana and its 129 thousand-base pair plastid and 44 thousand-base pair mitochondrial genomes. Sequence and optical restriction mapping revealed 24 diploid nuclear chromosomes. We identified novel genes for silicic acid transport and formation of silica-based cell walls, high-affinity iron uptake, biosynthetic enzymes for several types of polyunsaturated fatty acids, use of a range of nitrogenous compounds, and a complete urea cycle, all attributes that allow diatoms to prosper in aquatic environments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Armbrust, E Virginia -- Berges, John A -- Bowler, Chris -- Green, Beverley R -- Martinez, Diego -- Putnam, Nicholas H -- Zhou, Shiguo -- Allen, Andrew E -- Apt, Kirk E -- Bechner, Michael -- Brzezinski, Mark A -- Chaal, Balbir K -- Chiovitti, Anthony -- Davis, Aubrey K -- Demarest, Mark S -- Detter, J Chris -- Glavina, Tijana -- Goodstein, David -- Hadi, Masood Z -- Hellsten, Uffe -- Hildebrand, Mark -- Jenkins, Bethany D -- Jurka, Jerzy -- Kapitonov, Vladimir V -- Kroger, Nils -- Lau, Winnie W Y -- Lane, Todd W -- Larimer, Frank W -- Lippmeier, J Casey -- Lucas, Susan -- Medina, Monica -- Montsant, Anton -- Obornik, Miroslav -- Parker, Micaela Schnitzler -- Palenik, Brian -- Pazour, Gregory J -- Richardson, Paul M -- Rynearson, Tatiana A -- Saito, Mak A -- Schwartz, David C -- Thamatrakoln, Kimberlee -- Valentin, Klaus -- Vardi, Assaf -- Wilkerson, Frances P -- Rokhsar, Daniel S -- New York, N.Y. -- Science. 2004 Oct 1;306(5693):79-86.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Oceanography, University of Washington, Seattle, WA 98195, USA. armbrust@ocean.washington.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15459382" target="_blank"〉PubMed〈/a〉
