  • New Zealand's Genetic Diversity
    1.13 NEW ZEALAND’S GENETIC DIVERSITY NEW ZEALAND’S GENETIC DIVERSITY Dennis P. Gordon National Institute of Water and Atmospheric Research, Private Bag 14901, Kilbirnie, Wellington 6022, New Zealand ABSTRACT: The known genetic diversity represented by the New Zealand biota is reviewed and summarised, largely based on a recently published New Zealand inventory of biodiversity. All kingdoms and eukaryote phyla are covered, updated to refl ect the latest phylogenetic view of Eukaryota. The total known biota comprises a nominal 57 406 species (c. 48 640 described). Subtraction of the 4889 naturalised-alien species gives a biota of 52 517 native species. A minimum (the status of a number of the unnamed species is uncertain) of 27 380 (52%) of these species are endemic (cf. 26% for Fungi, 38% for all marine species, 46% for marine Animalia, 68% for all Animalia, 78% for vascular plants and 91% for terrestrial Animalia). In passing, examples are given both of the roles of the major taxa in providing ecosystem services and of the use of genetic resources in the New Zealand economy. Key words: Animalia, Chromista, freshwater, Fungi, genetic diversity, marine, New Zealand, Prokaryota, Protozoa, terrestrial. INTRODUCTION Article 10b of the CBD calls for signatories to ‘Adopt The original brief for this chapter was to review New Zealand’s measures relating to the use of biological resources [i.e. genetic genetic resources.

More than 30 species have been isolated but only N. fowleri has been associated with human disease. N. fowleri causes primary amoebic meningoencephalitis (PAM), an acute, often fulminant infection of CNS. Here we report a rare and first case of PAM in an immunocompetent elderly patient from this part of the country. Amoeboid and flagellate forms of N. fowleri were detected in the direct microscopic examination of CSF and confirmed by flagellation test in distilled water, demonstrating plaques /clear areas on 1.5% non nutrient agar and its survival at 42°C. Keywords: Meningitis, Naegleria fowleri, primary amoebic meningoencephalitis Introduction of our knowledge, in India, only eight cases have been reported so far .1, 5-8 Infection of the central nervous system (CNS) in human We hereby report a rare case of PAM in elderly beings with free living amoebae is uncommon.

Accepted: 29 September 2003 Protist large-scale phylogeny is briefly reviewed and a revised higher classification of the kingdom Pro- tozoa into 11 phyla presented. Complementary gene fusions reveal a fundamental bifurcation among eu- karyotes between two major clades: the ancestrally uniciliate (often unicentriolar) unikonts and the an- cestrally biciliate bikonts, which undergo ciliary transformation by converting a younger anterior cilium into a dissimilar older posterior cilium. Unikonts comprise the ancestrally unikont protozoan phylum Amoebozoa and the opisthokonts (kingdom Animalia, phylum Choanozoa, their sisters or ancestors; and kingdom Fungi). They share a derived triple-gene fusion, absent from bikonts. Bikonts contrastingly share a derived gene fusion between dihydrofolate reductase and thymidylate synthase and include plants and all other protists, comprising the protozoan infrakingdoms Rhizaria [phyla Cercozoa and Re- taria (Radiozoa, Foraminifera)] and Excavata (phyla Loukozoa, Metamonada, Euglenozoa, Percolozoa), plus the kingdom Plantae [Viridaeplantae, Rhodophyta (sisters); Glaucophyta], the chromalveolate clade, and the protozoan phylum Apusozoa (Thecomonadea, Diphylleida). Chromalveolates comprise kingdom Chromista (Cryptista, Heterokonta, Haptophyta) and the protozoan infrakingdom Alveolata [phyla Cilio- phora and Miozoa (= Protalveolata, Dinozoa, Apicomplexa)], which diverged from a common ancestor that enslaved a red alga and evolved novel plastid protein-targeting machinery via the host rough ER and the enslaved algal plasma membrane (periplastid membrane).

To address this question I have undertaken a molecular phylogenetic study of two candidate lineages to determine the first sexual line. In my thesis the hypermastigotes are confirmed as closely related to the trichomonads in the phylum Parabasalia and found to be more deeply divergent than a putative pyrsonymphid. This means that the Parabasalia are the first sexual lineage. From this I go on to infer that the ancestral sexual cycle included facultative sex.

Downloaded from Abstract Discoba(Excavata)isanancientgroupof eukaryotes withgreatmorphological andecologicaldiversity.Unlikethe other major divisions http://gbe.oxfordjournals.org/ of Discoba (Jakobida and Euglenozoa), little is known about the mitochondrial DNAs (mtDNAs) of Heterolobosea. We have assembled a complete mtDNA genome from the aggregating heterolobosean amoeba, Acrasis kona, which consists of a single circular highly AT- rich (83.3%) molecule of 51.5 kb. Unexpectedly, A. kona mtDNA is missing roughly 40% of the protein-coding genes and nearly half of the transfer RNAs found in the only other sequenced heterolobosean mtDNAs, those of Naegleria spp. Instead, over a quarter of A. kona mtDNA consists of novel open reading frames. Eleven of the 16 protein-coding genes missing from A. kona mtDNA were identified in its nuclear DNA and polyA RNA, and phylogenetic analyses indicate that at least 10 of these 11 putative nuclear-encoded mitochondrial (NcMt) proteins arose by direct transfer from the mitochondrion.

  • The Amoeboid Parabasalid Flagellate Gigantomonas Herculeaof
    Acta Protozool. (2005) 44: 189 - 199 The Amoeboid Parabasalid Flagellate Gigantomonas herculea of the African Termite Hodotermes mossambicus Reinvestigated Using Immunological and Ultrastructural Techniques Guy BRUGEROLLE Biologie des Protistes, UMR 6023, CNRS and Université Blaise Pascal de Clermont-Ferrand, Aubière Cedex, France Summary. The amoeboid form of Gigantomonas herculea (Dogiel 1916, Kirby 1946), a symbiotic flagellate of the grass-eating subterranean termite Hodotermes mossambicus from East Africa, is observed by light, immunofluorescence and transmission electron microscopy. Amoeboid cells display a hyaline margin and a central granular area containing the nucleus, the internalized flagellar apparatus, and organelles such as Golgi bodies, hydrogenosomes, and food vacuoles with bacteria or wood particles. Immunofluorescence microscopy using monoclonal antibodies raised against Trichomonas vaginalis cytoskeleton, such as the anti-tubulin IG10, reveals the three long anteriorly-directed flagella, and the axostyle folded into the cytoplasm. A second antibody, 4E5, decorates the conspicuous crescent-shaped structure or cresta bordered by the adhering recurrent flagellum. Transmission electron micrographs show a microfibrillar network in the cytoplasmic margin and internal bundles of microfilaments similar to those of lobose amoebae that are indicative of cytoplasmic streaming. They also confirm the internalization of the flagella. The arrangement of basal bodies and fibre appendages, and the axostyle composed of a rolled sheet of microtubules are very close to that of the devescovinids Foaina and Devescovina. The very large microfibrillar cresta supporting an enlarged recurrent flagellum resembles that of Macrotrichomonas. The parabasal apparatus attached to the basal bodies is small in comparison to the cell size; this is probably related to the presence of many Golgi bodies supported by a striated fibre that are spread throughout the central cytoplasm in a similar way to Placojoenia and Mixotricha.

Previous work has divided eukaryotic diversity into a small number of high-level ‘supergroups’, many of which receive strong support in phylogenomic analyses. However, the abundance of data in phylogenomic analyses can lead to highly supported but incorrect relationships due to systematic phylogenetic error. Further, the paucity of major eukaryotic lineages (19 or fewer) included in these genomic studies may exaggerate systematic error and reduces power to evaluate hypotheses.

  • Archezoa and the Origin of Eukaryotes Patrick J
    Problems and paradigms A kingdom’s progress: Archezoa and the origin of eukaryotes Patrick J. Keeling* Summary The taxon Archezoa was proposed to unite a group of very odd eukaryotes that lack many of the characteristics classically associated with nucleated cells, in particular the mitochondrion. The hypothesis was that these cells diverged from other eukaryotes before these characters ever evolved, and therefore they repre- sent ancient and primitive eukaryotic lineages. The kingdom comprised four groups: Metamonada, Microsporidia, Parabasalia, and Archamoebae. Until re- cently, molecular work supported their primitive status, as they consistently branched deeply in eukaryotic phylogenetic trees. However, evidence has now emerged that many Archezoa contain genes derived from the mitochondrial symbiont, revealing that they actually evolved after the mitochondrial symbiosis. In addition, some Archezoa have now been shown to have evolved more recently than previously believed, especially the Microsporidia for which considerable evidence now indicates a relationship with fungi. In summary, the mitochondrial symbiosis now appears to predate all Archezoa and perhaps all presently known eukaryotes. BioEssays 20:87–95, 1998. ௠ 1998 John Wiley & Sons, Inc. INTRODUCTION cyanobacteria and they also lack flagella and basal bodies Prior to the popularization of the endosymbiotic theory, it was (for discussion see Ref. 1). However, according to the widely believed that the evolutionary link between prokary- endosymbiotic theory, the reason photosynthesis is so simi- otes and eukaryotes was the presence of photosynthesis in lar in cyanobacteria and photosynthetic eukaryotes is that cyanobacteria and algae. The biochemistry of oxygenic the plastids of plant and algal cells are derived from a photosynthesis was considered too complicated and too cyanobacterial symbiont.
