CARPENTER, LAWRENCE CHOW and PATRICK J. KEELING Canadian Institute for Advanced Research, Botany Department, University of British Columbia, University Boulevard, Vancouver, BC, Canada V6T 1Z4 ABSTRACT. Trichonympha is one of the most complex and visually striking of the hypermastigote parabasalids—a group of anaerobic flagellates found exclusively in hindguts of lower termites and the wood-feeding cockroach Cryptocercus—but it is one of only two genera common to both groups of insects. We investigated Trichonympha of Cryptocercus using light and electron microscopy (scanning and transmission), as well as molecular phylogeny, to gain a better understanding of its morphology, diversity, and evolution. Microscopy reveals numerous new features, such as previously undetected bacterial surface symbionts, adhesion of post-rostral flagella, and a dis- tinctive frilled operculum. We also sequenced small subunit rRNA gene from manually isolated species, and carried out an environmental polymerase chain reaction (PCR) survey of Trichonympha diversity, all of which strongly supports monophyly of Trichonympha from Cryptocercus to the exclusion of those sampled from termites. Bayesian and distance methods support a relationship between Tricho- nympha species from termites and Cryptocercus, although likelihood analysis allies the latter with Eucomonymphidae. A monophyletic Trichonympha is of great interest because recent evidence supports a sister relationship between Cryptocercus and termites, suggesting Trichonympha predates the Cryptocercus-termite divergence. -

Living Euglena cells and 30 non-living Euglena biomass were examined for their capacity to sorb metal ions. 31 Adsorption isotherms were used in batch systems to describe the kinetic and equilibrium 32 characteristics of metal removal. In living systems results indicate that the sorption 33 reaction occurs quickly (<30 min) in both Cu (II) and Ni (II) mono-metallic systems and 34 adsorption follows a pseudo-second order kinetics model for both metals. Sorption 35 capacity and intensity was greater for Cu than Ni (p < 0.05) and were described by the 36 Freundlich model. In bi-metallic systems sorption of both metals appears equivalent. In 37 non-living systems sorption occurred quickly (10-30 min) and both Cu and Ni 38 equilibrium uptake increased with a concurrent increase of initial metal concentrations. 39 The pseudo-first-order model was applied to the kinetic data and the Langmuir and 40 Freundlich models effectively described single-metal systems. -
Evolution and Comparative Morphology of the Euglenophyte
EVOLUTION AND COMPARATIVE MORPHOLOGY OF THE EUGLENOPHYTE PLASTID by PATRICK JERRY PAUL BROWN (Under the Direction of Mark A. Farmer) ABSTRACT My doctoral research centered on understanding the evolution of the euglenophyte protists, with special attention paid to their plastids. The euglenophytes are a widely distributed group of euglenid protists that have acquired a chloroplast via secondary symbiogenesis. The goals of my research were to 1) test the efficacy of plastid morphological and ultrastructural characters in phylogenetic analysis; 2) understand the process of plastid development and partitioning in the euglenophytes; 3) to use a plastid- encoded protein gene to determine a euglenophyte phylogeny; and 4) to perform a multi- gene analysis to uncover clues about the origins of the euglenophyte plastid. My work began with an alpha-taxonomic study that redefined the rare euglenophyte Euglena rustica. This work not only validly circumscribed the species, but also noted novel features of its habitat, cyclic migration habits, and cellular biology. This was followed by a study of plastid morphology and development in a number of diverse euglenophytes. The results of this study showed that the plastids of euglenophytes undergo drastic changes in morphology and ultrastructure over the course of a single cell division cycle. I concluded that there are four main classes of plastid development and partitioning in the euglenophytes, and that the class a given species will use is dependant on its interphase plastid morphology and the rigidity of the cell. The discovery of the class IV partitioning strategy in which cells with only one or very few plastids fragment their plastids prior to cell division was very significant. -
Trichonympha Burlesquei N. Sp. from Reticulitermes Virginicus and Evidence Against a Cosmopolitan Distribution of Trichonympha Agilis in Many Termite Hosts

James,1 Vera Tai,1 Rudolf H. Scheffrahn2 and Patrick J. Keeling1 Correspondence 1Canadian Institute for Advanced Research, Department of Botany, University of British Columbia, Patrick J. Keeling Vancouver, BC, Canada [email protected] 2University of Florida Research & Education Center, 3205 College Avenue, Davie, FL 33314, USA Historically, symbiotic protists in termite hindguts have been considered to be the same species if they are morphologically similar, even if they are found in different host species. For example, the first-described hindgut and hypermastigote parabasalian, Trichonympha agilis (Leidy, 1877) has since been documented in six species of Reticulitermes, in addition to the original discovery in Reticulitermes flavipes. Here we revisit one of these, Reticulitermes virginicus, using molecular phylogenetic analysis from single-cell isolates and show that the Trichonympha in R. virginicus is distinct from isolates in the type host and describe this novel species as Trichonympha burlesquei n. sp. We also show the molecular diversity of Trichonympha from the type host R. flavipes is greater than supposed, itself probably representing more than one species. All of this is consistent with recent data suggesting a major underestimate of termite symbiont diversity. Members of the genus Trichonympha are large and species of termite: in practice, similar-looking symbionts of structurally complex parabasalians exclusively found in the genus Trichonympha from different termite species are the symbiotic, lignocellulose-digesting hindgut community assumed to be the same species. -
Molecular Characterization and Phylogeny of Four New Species of the Genus Trichonympha (Parabasalia, Trichonymphea) from Lower Termite Hindguts
TAXONOMIC DESCRIPTION Boscaro et al., Int J Syst Evol Microbiol 2017;67:3570–3575 DOI 10.1099/ijsem.0.002169 Molecular characterization and phylogeny of four new species of the genus Trichonympha (Parabasalia, Trichonymphea) from lower termite hindguts Vittorio Boscaro,1,* Erick R. James,1 Rebecca Fiorito,1 Elisabeth Hehenberger,1 Anna Karnkowska,1,2 Javier del Campo,1 Martin Kolisko,1,3 Nicholas A. T. Irwin,1 Varsha Mathur,1 Rudolf H. Scheffrahn4 and Patrick J. Keeling1 Abstract Members of the genus Trichonympha are among the most well-known, recognizable and widely distributed parabasalian symbionts of lower termites and the wood-eating cockroach species of the genus Cryptocercus. Nevertheless, the species diversity of this genus is largely unknown. Molecular data have shown that the superficial morphological similarities traditionally used to identify species are inadequate, and have challenged the view that the same species of the genus Trichonympha can occur in many different host species. Ambiguities in the literature, uncertainty in identification of both symbiont and host, and incomplete samplings are limiting our understanding of the systematics, ecology and evolution of this taxon. Here we describe four closely related novel species of the genus Trichonympha collected from South American and Australian lower termites: Trichonympha hueyi sp. nov. from Rugitermes laticollis, Trichonympha deweyi sp. nov. from Glyptotermes brevicornis, Trichonympha louiei sp. nov. from Calcaritermes temnocephalus and Trichonympha webbyae sp. nov. from Rugitermes bicolor. We provide molecular barcodes to identify both the symbionts and their hosts, and infer the phylogeny of the genus Trichonympha based on small subunit rRNA gene sequences. The analysis confirms the considerable divergence of symbionts of members of the genus Cryptocercus, and shows that the two clades of the genus Trichonympha harboured by termites reflect only in part the phylogeny of their hosts. -

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. -
That of a Typical Flagellate. the Flagella May Equally Well Be Called Cilia
ZOOLOGY; KOFOID AND SWEZY 9 FLAGELLATE AFFINITIES OF TRICHONYMPHA BY CHARLES ATWOOD KOFOID AND OLIVE SWEZY ZOOLOGICAL LABORATORY, UNIVERSITY OF CALIFORNIA Communicated by W. M. Wheeler, November 13, 1918 The methods of division among the Protozoa are of fundamental signifi- cance from an evolutionary standpoint. Unlike the Metazoa which present, as a whole, only minor variations in this process in the different taxonomic groups and in the many different types of cells in the body, the Protozoa have evolved many and widely diverse types of mitotic phenomena, which are Fharacteristic of the groups into which the phylum is divided. Some strik- ing confirmation of the value of this as a clue to relationships has been found in recent work along these lines. The genus Trichonympha has, since its discovery in 1877 by Leidy,1 been placed, on the one hand, in the ciliates and, on the other, in the flagellates, and of late in an intermediate position between these two classes, by different investigators. Certain points in its structure would seem to justify each of these assignments. A more critical study of its morphology and especially of its methods of division, however, definitely place it in the flagellates near the Polymastigina. At first glance Trichonympha would undoubtedly be called a ciliate. The body is covered for about two-thirds of its surface with a thick coating of cilia or flagella of varying lengths, which stream out behind the body. It also has a thick, highly differentiated ectoplasm which contains an alveolar layer as well as a complex system of myonemes. -

Phylogeny of Deep-Level Relationships Within Euglenozoa Based on Combined Small Subunit and Large Subunit Ribosomal DNA Sequence
PHYLOGENY OF DEEP-LEVEL RELATIONSHIPS WITHIN EUGLENOZOA BASED ON COMBINED SMALL SUBUNIT AND LARGE SUBUNIT RIBOSOMAL DNA SEQUENCES by BING MA (Under the Direction of Mark A. Farmer) ABSTRACT My master’s research addressed questions about the evolutionary histories of Euglenozoa, with special attention given to deep-level relationships among taxa. The Euglenozoa are a putative early-branching assemblage of flagellated Eukaryotes, comprised primarily by three subgroups: euglenids, kinetoplastids and diplonemids. The goals of my research were to 1) evaluate the phylogenetic potential of large subunit ribosomal DNA (LSU rDNA) gene sequences as a molecular marker; 2) construct a phylogeny for the Euglenozoa to address their deep-level relationships; 3) provide morphological data of the flagellate Petalomonas cantuscygni to infer its evolutionary position in Euglenozoa. A dataset based on LSU rDNA sequences combined with SSU rDNA from thirty-nine taxa representing every subgroup of Euglenozoa and outgroup species was used for testing relationships within the Euglenozoa. Our results indicate that a) LSU rDNA is a useful marker to infer phylogeny, b) euglenids and diplonemdis are more closely related to one another than either is to the kinetoplatids and c) Petalomonas cantuscygni is closely related to the diplonemids.
