The Chloroplast Rpl23 Gene Cluster of Spirogyra Maxima (Charophyceae) Shares Many Similarities with the Angiosperm Rpl23 Operon
Algae Volume 17(1): 59-68, 2002 The Chloroplast rpl23 Gene Cluster of Spirogyra maxima (Charophyceae) Shares Many Similarities with the Angiosperm rpl23 Operon Jungho Lee* and James R. Manhart Department of Biology, Texas A&M University, College Station, TX, 77843-3258, U.S.A. A phylogenetic affinity between charophytes and embryophytes (land plants) has been explained by a few chloro- plast genomic characters including gene and intron (Manhart and Palmer 1990; Baldauf et al. 1990; Lew and Manhart 1993). Here we show that a charophyte, Spirogyra maxima, has the largest operon of angiosperm chloroplast genomes, rpl23 operon (trnI-rpl23-rpl2-rps19-rpl22-rps3-rpl16-rpl14-rps8-infA-rpl36-rps11-rpoA) containing both embryophyte introns, rpl16.i and rpl2.i. The rpl23 gene cluster of Spirogyra contains a distinct eubacterial promoter sequence upstream of rpl23, which is the first gene of the green algal rpl23 gene cluster. This sequence is completely absent in angiosperms but is present in non-flowering plants. The results imply that, in the rpl23 gene cluster, early charophytes had at least two promoters, one upstream of trnI and another upstream of rpl23, which partially or completely lost its function in land plants. A comparison of gene clusters of prokaryotes, algal chloroplast DNAs and land plant cpDNAs indicated a loss of numerous genes in chlorophyll a+b eukaryotes. A phylogenetic analysis using presence/absence of genes and introns as characters produced trees with a strongly supported clade contain- ing chlorophyll a+b eukaryotes. Spirogyra and embryophytes formed a clade characterized by the loss of rpl5 and rps9 and the gain of trnI (CAU) and introns in rpl2 and rpl16. -

It’s how nature creates itself, on every scale, the snowflake and the snowstorm. — TOM STOPPARD, Arcadia, Act 1, Scene 4 (1993) Much has been written about evolution from the perspective of the history and biology of animals, but significantly less has been writ- ten about the evolutionary biology of plants. Zoocentricism in the biological literature is understandable to some extent because we are after all animals and not plants and because our self- interest is not entirely egotistical, since no biologist can deny the fact that animals have played significant and important roles as the actors on the stage of evolution come and go. The nearly romantic fascination with di- nosaurs and what caused their extinction is understandable, even though we should be equally fascinated with the monarchs of the Carboniferous, the tree lycopods and calamites, and with what caused their extinction (fig. 0.1). Yet, it must be understood that plants are as fascinating as animals, and that they are just as important to the study of biology in general and to understanding evolutionary theory in particular. -

Biology and Systematics of Heterokont and Haptophyte Algae1
American Journal of Botany 91(10): 1508±1522. 2004. BIOLOGY AND SYSTEMATICS OF HETEROKONT AND HAPTOPHYTE ALGAE1 ROBERT A. ANDERSEN Bigelow Laboratory for Ocean Sciences, P.O. Box 475, West Boothbay Harbor, Maine 04575 USA In this paper, I review what is currently known of phylogenetic relationships of heterokont and haptophyte algae. Heterokont algae are a monophyletic group that is classi®ed into 17 classes and represents a diverse group of marine, freshwater, and terrestrial algae. Classes are distinguished by morphology, chloroplast pigments, ultrastructural features, and gene sequence data. Electron microscopy and molecular biology have contributed signi®cantly to our understanding of their evolutionary relationships, but even today class relationships are poorly understood. Haptophyte algae are a second monophyletic group that consists of two classes of predominately marine phytoplankton. The closest relatives of the haptophytes are currently unknown, but recent evidence indicates they may be part of a large assemblage (chromalveolates) that includes heterokont algae and other stramenopiles, alveolates, and cryptophytes. Heter- okont and haptophyte algae are important primary producers in aquatic habitats, and they are probably the primary carbon source for petroleum products (crude oil, natural gas). Key words: chromalveolate; chromist; chromophyte; ¯agella; phylogeny; stramenopile; tree of life. Heterokont algae are a monophyletic group that includes all (Phaeophyceae) by Linnaeus (1753), and shortly thereafter, photosynthetic organisms with tripartite tubular hairs on the microscopic chrysophytes (currently 5 Oikomonas, Anthophy- mature ¯agellum (discussed later; also see Wetherbee et al., sa) were described by MuÈller (1773, 1786). The history of 1988, for de®nitions of mature and immature ¯agella), as well heterokont algae was recently discussed in detail (Andersen, as some nonphotosynthetic relatives and some that have sec- 2004), and four distinct periods were identi®ed. -
Centers of Endemism of Freshwater Protists Deviate from Pattern of Taxon Richness on a Continental Scale Jana L
www.nature.com/scientificreports OPEN Centers of endemism of freshwater protists deviate from pattern of taxon richness on a continental scale Jana L. Olefeld1, Christina Bock1, Manfred Jensen1, Janina C. Vogt2, Guido Sieber1, Dirk Albach2 & Jens Boenigk1* Here, we analyzed patterns of taxon richness and endemism of freshwater protists in Europe. Even though the signifcance of physicochemical parameters but also of geographic constraints for protist distribution is documented, it remains unclear where regional areas of high protist diversity are located and whether areas of high taxon richness harbor a high proportion of endemics. Further, patterns may be universal for protists or deviate between taxonomic groups. Based on amplicon sequencing campaigns targeting the SSU and ITS region of the rDNA we address these patterns at two diferent levels of phylogenetic resolution. Our analyses demonstrate that protists have restricted geographical distribution areas. For many taxonomic groups the regions of high taxon richness deviate from those having a high proportion of putative endemics. In particular, the diversity of high mountain lakes as azonal habitats deviated from surrounding lowlands, i.e. many taxa were found exclusively in high mountain lakes and several putatively endemic taxa occurred in mountain regions like the Alps, the Pyrenees or the Massif Central. Beyond that, taxonomic groups showed a pronounced accumulation of putative endemics in distinct regions, e.g. Dinophyceae along the Baltic Sea coastline, and Chrysophyceae in Scandinavia. Many other groups did not have pronounced areas of increased endemism but geographically restricted taxa were found across Europe. Restricted distribution and endemism has been demonstrated for numerous protist taxa by now 1–4. -

The history of the HUCP had its beginning in the middle of the 1970s with the foundation of the Biology Museum that gathered both botanical and zoological specimens. In April 1979 collections were separated and the HUCP was founded with preserved specimens of algae (green, red, and brown), fungi, and embryophytes. As of October 2016, the collection encompasses nearly 25,000 specimens from 4934 species, 1609 genera, and 297 families. Most of the specimens comes from the state of Paraná but there were also specimens from many Brazilian states and other countries, mainly from South America (Chile, Argentina, Uruguay, Paraguay, and Colombia) but also from other parts of the world (Cuba, USA, Spain, Germany, China, and Australia). Our collection includes 42 fungi, 258 gymnosperms, 299 bryophytes, 2809 pteridophytes, 3158 algae, 17,832 angiosperms, and only one type of Mimosa (Mimosa tucumensis Barneby ex Ribas, M. -

Plant of the Week Liverworts
Plant of the Week LLiivveerrwwoorrttss It is hard to believe that a group of plants that includes so many beautiful species, has been saddled with such an awful name. The name liverwort comes from the Anglo- Saxon word “lifer” (liver) and “wyrt” (a plant), the inference being that plants that look like organs of the human body might 1 Telaranea centipes – a leafy provide medicinal benefits for that organ . liverwort Photo: Ron Oldfield Liverworts are close relatives of mosses. Traditionally, they were considered to be one class (Hepaticae) of the division Bryophyta of the Plant Kingdom. The other two classes were the mosses (musci) and the hornworts (Anthocerotae). Using modern molecular techniques, botanists have now elevated each of these classes to divisions of the plant kingdom, so now only mosses belong to the Division Bryophyta. Liverworts are placed in the Division Marchantiophyta and hornworts in the Division Anthocerophyta. All three divisions are now collectively referred to as “Embryophytes”, that is, land plants that do not have a vascular system. Embryophytes are believed to have evolved from a family of freshwater algae, the Charophyceae. In 1994, it was proposed that the three lineages of bryophytes, formed a gradient leading to the vascular plants. The most recent hypothesis is that hornworts share a common ancestor with vascular plants and liverworts are a sister lineage to all other extant embryophytes. Mosses bridge the gap between liverworts 2 and hornworts . Liverworts Mosses Hornworts Tracheophyte s Charophyceae Lunularia cruciata – a thallose liverwort Photo: Ron Oldfield There are two readily identifiable groups of liverworts: thallose liverworts appear to be relatively simple structures, and form flattened green plates that are not differentiated into stems and leaves. -
