    Notes: Summary The origin and phylogeny of the Guinea yams, consisting of the white yam (Dioscorea rotundata Poir.) and the yellow yam (D. cayenensis Lamk.), has been investigated. Fourteen cultivars of Guinea yams were sampled with 12 accessions from seven wild yam species. A total of 26 accessions were surveyed for restriction fragment length polymorphisms (RFLP) in chloroplast DNA (cpDNA) and nuclear ribosomal DNA (rDNA) using seven restriction endonucleases and various heterologous probes. Chloroplast DNA probes covering 80% of the total chloroplast genome revealed nine restriction site changes and one length mutation among the cpDNAs of Guinea yams and their wild relatives. The estimated numbers of nucleotide substitutions per site (d) among these cpDNAs were very low (0.0005–0.0027), indicating a rather recent divergence of this group. On the basis of these ten mutations, five chloroplast genome types (A-E) were recognized. It was revealed that two cultivated species (D. rotundata and D. cayenensis) display the same chloroplast genome type, type A, as the three wild species D. praehensilis, D. liebrechtsiana and D. abyssinica. Chloroplast genome types B, C, D and E were found in D. minutiflora, D. burkilliana, D. smilacifolia and D. togoensis, respectively. Maximum parsimony analysis produced a hypothetical phylogeny of three primary lineages among cpDNAs of Guinea yams and their relatives: the genome type A lineage, the genome type B lineage and one lineage including genome types C, D and E. Using rDNA clones of rice and taro as probes, we detected ribosomal DNA variation, presumably at the intergenic spacer region, in Guinea yams and their wild relatives. The survey of rDNA together with that of cpDNA indicates that D. rotundata (white yam) was domesticated from either D. abyssinica, D. liebrechtsiana or D. praehensilis or their hybrid, and that D. cayenensis (yellow yam) is derived from hybridization between a male plant of either D. burkilliana, D. minutiflora or D. smilacifolia and a female plant of either D. rotundata, D. abyssinica, D. liebrechtsiana or D. praehensilis. We propose that the previous nomenclature of white yam should be retained, D. rotundata Poir. nomen nudum, and that yellow yam should be treated as a variety of D. rotundata, denoted as D. rotundata var. x ‘cayenensis’.

    Intraspecific variation of chloroplast DNA in Dioscorea bulbifera L. (1991)

    Notes: Summary Restriction fragment length polymorphism (RFLP) analysis of chloroplast (ct) DNAs from 15 accessions of Dioscorea bulbifera collected from Africa and Asia was carried out using the Southern hybridization technique. Eight cloned ctDNA fragments of D. bulbifera and D. opposita, which cover 80% of the total chloroplast genome, were used as the probes to detect variation in ctDNA digested with nine restriction endonucleases. Ten variable sites, located in the large and small single-copy regions, were disclosed among the 15 accessions, of which six showed base substitution and four carried length mutation. Positions of the latter mutations were determined on the physical map of ctDNA. Based on these results, chloroplast genomes of the 15 accessions could be classified into nine types. Their phylogenetic relationships are assumed to be as follows: (1) African and Asian chloroplast genomes diverged from each other at the earliest point in time; (2) E-type chloroplast genome, occurring in the south-east edge of the Asian continent, appears to be the most ancient among all the Asian chloroplast genomes; and (3) four chloroplast genomes, found in Asian insular regions, are probably derived independently from the E-type genome. The discrepancy between the taxonomic relationship and the proposed chloroplast genome phylogeny of the present materials is noted.

    Phylogenetic relationships among genera in theLiliaceae-Asparagoideae-Polygonatae s.l. inferred fromrbcL gene sequence data (1994)

    Notes: Abstract The chloroplast gene encoding ribulose-1,5-bisphosphate-carboxylase (rbcL) was sequenced for phylogenetic analysis of 13 species (10 genera) in the tribePolygonatae s.l. of theLiliaceae-Asparagoideae. The data were analysed using maximum parsimony and neighbour-joining methods. There were 233 phylogenetically informative sites out of 1368 base pairs compared. The results suggest that there are three monophyletic groups withinPolygonatae s.l. with high bootstrap confidence values. Group A representsPolygonatae s.str., with generaMaianthemum, Smilacina, Convallaria, Disporopsis, andPolygonatum. Group B containsUvularia andDisporum and group C includesStreptopus, Tricyrtis, Clintonia, andProsartes. The study suggests thatPolygonatae s.l. are not a monophyletic group, including at least three groups of different phylogenetic origin. Monophyly of the taxa within groups A, B, and C is supported by the high bootstrap confidence values (85–100%) of the bootstrap replications for both parsimony and neighbour-joining methods. The differences between each group (calculated as 100x base substitutions per site) were 6.99–9.03 for group A and B, 4.92–7.35 for A and C, and 6.66–7.57 for B and C.

    The Chlamydomonas genome reveals the evolution of key animal and plant functions (2007)
    American Association for the Advancement of Science (AAAS)

    Publication Date: 2007-10-13
    Description: Chlamydomonas reinhardtii is a unicellular green alga whose lineage diverged from land plants over 1 billion years ago. It is a model system for studying chloroplast-based photosynthesis, as well as the structure, assembly, and function of eukaryotic flagella (cilia), which were inherited from the common ancestor of plants and animals, but lost in land plants. We sequenced the approximately 120-megabase nuclear genome of Chlamydomonas and performed comparative phylogenomic analyses, identifying genes encoding uncharacterized proteins that are likely associated with the function and biogenesis of chloroplasts or eukaryotic flagella. Analyses of the Chlamydomonas genome advance our understanding of the ancestral eukaryotic cell, reveal previously unknown genes associated with photosynthetic and flagellar functions, and establish links between ciliopathy and the composition and function of flagella.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2875087/" 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/PMC2875087/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Merchant, Sabeeha S -- Prochnik, Simon E -- Vallon, Olivier -- Harris, Elizabeth H -- Karpowicz, Steven J -- Witman, George B -- Terry, Astrid -- Salamov, Asaf -- Fritz-Laylin, Lillian K -- Marechal-Drouard, Laurence -- Marshall, Wallace F -- Qu, Liang-Hu -- Nelson, David R -- Sanderfoot, Anton A -- Spalding, Martin H -- Kapitonov, Vladimir V -- Ren, Qinghu -- Ferris, Patrick -- Lindquist, Erika -- Shapiro, Harris -- Lucas, Susan M -- Grimwood, Jane -- Schmutz, Jeremy -- Cardol, Pierre -- Cerutti, Heriberto -- Chanfreau, Guillaume -- Chen, Chun-Long -- Cognat, Valerie -- Croft, Martin T -- Dent, Rachel -- Dutcher, Susan -- Fernandez, Emilio -- Fukuzawa, Hideya -- Gonzalez-Ballester, David -- Gonzalez-Halphen, Diego -- Hallmann, Armin -- Hanikenne, Marc -- Hippler, Michael -- Inwood, William -- Jabbari, Kamel -- Kalanon, Ming -- Kuras, Richard -- Lefebvre, Paul A -- Lemaire, Stephane D -- Lobanov, Alexey V -- Lohr, Martin -- Manuell, Andrea -- Meier, Iris -- Mets, Laurens -- Mittag, Maria -- Mittelmeier, Telsa -- Moroney, James V -- Moseley, Jeffrey -- Napoli, Carolyn -- Nedelcu, Aurora M -- Niyogi, Krishna -- Novoselov, Sergey V -- Paulsen, Ian T -- Pazour, Greg -- Purton, Saul -- Ral, Jean-Philippe -- Riano-Pachon, Diego Mauricio -- Riekhof, Wayne -- Rymarquis, Linda -- Schroda, Michael -- Stern, David -- Umen, James -- Willows, Robert -- Wilson, Nedra -- Zimmer, Sara Lana -- Allmer, Jens -- Balk, Janneke -- Bisova, Katerina -- Chen, Chong-Jian -- Elias, Marek -- Gendler, Karla -- Hauser, Charles -- Lamb, Mary Rose -- Ledford, Heidi -- Long, Joanne C -- Minagawa, Jun -- Page, M Dudley -- Pan, Junmin -- Pootakham, Wirulda -- Roje, Sanja -- Rose, Annkatrin -- Stahlberg, Eric -- Terauchi, Aimee M -- Yang, Pinfen -- Ball, Steven -- Bowler, Chris -- Dieckmann, Carol L -- Gladyshev, Vadim N -- Green, Pamela -- Jorgensen, Richard -- Mayfield, Stephen -- Mueller-Roeber, Bernd -- Rajamani, Sathish -- Sayre, Richard T -- Brokstein, Peter -- Dubchak, Inna -- Goodstein, David -- Hornick, Leila -- Huang, Y Wayne -- Jhaveri, Jinal -- Luo, Yigong -- Martinez, Diego -- Ngau, Wing Chi Abby -- Otillar, Bobby -- Poliakov, Alexander -- Porter, Aaron -- Szajkowski, Lukasz -- Werner, Gregory -- Zhou, Kemin -- Grigoriev, Igor V -- Rokhsar, Daniel S -- Grossman, Arthur R -- GM07185/GM/NIGMS NIH HHS/ -- GM42143/GM/NIGMS NIH HHS/ -- R01 GM032843/GM/NIGMS NIH HHS/ -- R01 GM042143/GM/NIGMS NIH HHS/ -- R01 GM042143-09/GM/NIGMS NIH HHS/ -- R01 GM060992/GM/NIGMS NIH HHS/ -- R01 GM062915-06/GM/NIGMS NIH HHS/ -- R37 GM030626/GM/NIGMS NIH HHS/ -- R37 GM042143/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Oct 12;318(5848):245-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biochemistry, University of California at Los Angeles, Los Angeles, CA 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17932292" target="_blank"〉PubMed〈/a〉
