Five molecu- lar markers from different genome compartments including rbcL, COI, 18S rDNA, psbA, and UPA were identified and used to construct a phylogenetic relationship. Phylogenetic analyses indicated that two different morphological types from China clustered into an independent clade with Compsopogon specimens when compared to other global samples. The Compsopogon clade exhibited robust support values, revealing the affiliation of the samples toCompsopogon cae- ruleus. Although the samples were distributed in a close geographical area, unexpected sequence divergences between the Chinese samples implied that they were introduced by different dispersal events and from varied origins. It was speculated that Compsopogon originated in North America, a portion of the Laurentia landmass situated in the Rodinia supercontinent at approximately 573.89-1,701.50 million years ago during the Proterozoic era. Although Compsopogon had evolved for a rather long time, genetic conservation had limited its variability and rate of evolution, resulting in the current monospecific global distribution. Additional global specimens and sequence information were required to in- crease our understanding of the evolutionary history of this ancient red algal lineage. Key Words: Compsopogon; divergence time; geographic origin; molecular analysis; morphology; phylogenetic relationship INTRODUCTION Compsopogon Montagne 1846 is a typical Rhodophyta tics are widely variable both within and among popula- algal genus that inhabits freshwater and is globally dis- tions and with different environmental factors (Necchi et tributed (Kumanoa 2002).

We examined the ultrastructure of both genera to compare with ultrastructure of other members of the class Compsopogonophyceae. Both genera had Golgi bodies not associated with mitochondria and chloroplasts with a peripheral encircling thylakoid similar to all other members of the class studied thus far. Confocal autofluorescence images showed that Madagascaria has a single round central pyrenoid while Pseudoerythrocladia has no pyrenoid. Our electron microscopic work confirms these initial observations. Tables and keys are presented that assist in interpreting cellular details of genera in the class Compsopogonophyceae. Key Words: chloroplasts; Compsopogononophyceae; Erythropeltidales; Golgi; pyrenoids; ultrastructure INTRODUCTION Detailed molecular and culture studies coupled investigated with transmission electron microscopy with ultrastructural observations enable us to discover (TEM) (Scott et al. 2008, Yokoyama et al. 2009), and significant new genera and species of microscopic and the presence of a peripheral encircling thylakoid in macroscopic red algae (e.g., West et al.

  • The Hawaiian Rhodophyta Biodiversity Survey
    Sherwood et al. BMC Plant Biology 2010, 10:258 http://www.biomedcentral.com/1471-2229/10/258 RESEARCH ARTICLE Open Access The Hawaiian Rhodophyta Biodiversity Survey (2006-2010): a summary of principal findings Alison R Sherwood1*, Akira Kurihara1,2, Kimberly Y Conklin1,3, Thomas Sauvage1, Gernot G Presting4 Abstract Background: The Hawaiian red algal flora is diverse, isolated, and well studied from a morphological and anatomical perspective, making it an excellent candidate for assessment using a combination of traditional taxonomic and molecular approaches. Acquiring and making these biodiversity data freely available in a timely manner ensures that other researchers can incorporate these baseline findings into phylogeographic studies of Hawaiian red algae or red algae found in other locations. Results: A total of 1,946 accessions are represented in the collections from 305 different geographical locations in the Hawaiian archipelago. These accessions represent 24 orders, 49 families, 152 genera and 252 species/ subspecific taxa of red algae. One order of red algae (the Rhodachlyales) was recognized in Hawaii for the first time and 196 new island distributional records were determined from the survey collections. One family and four genera are reported for the first time from Hawaii, and multiple species descriptions are in progress for newly discovered taxa. A total of 2,418 sequences were generated for Hawaiian red algae in the course of this study - 915 for the nuclear LSU marker, 864 for the plastidial UPA marker, and 639 for the mitochondrial COI marker. These baseline molecular data are presented as neighbor-joining trees to illustrate degrees of divergence within and among taxa.

It was speculated that Compsopogon originated in North America, a portion of the Laurentia landmass situated in the Rodinia supercontinent at approximately 573.89-1,701.50 million years ago during the Proterozoic era. Although Compsopogon had evolved for a rather long time, genetic conservation had limited its variability and rate of evolution, resulting in the current monospecific global distribution. Additional global specimens and sequence information were required to in- crease our understanding of the evolutionary history of this ancient red algal lineage.

Bot. 24 (1): 84-90. Tehran. A freshwater red algae, Compsopogon caeruleus was collected from current water canal on south of Tehran, Iran for the first time. It lives as epiphyte on Cladophora sp. (green algae) in cold water canal at a temperature of 8-10°C and at high speed at a depth of 30-50 cm. Thallus was macroscopic filamentous, grey to greyish–green, in the growing season abundantly branched. Branches made an acute angle with the axis (about, 20-70°). Thallus is 180-1000 μm in diameter and 2-10 cm long. In mature thallus, cortex had 1–2 polygonal or irregular cell layers with short spine-like branchlets. Cortical cells were established in regular or irregular rows. Chloroplasts were parietal. Monosporangia were cortical and semi-spherical to irregular.

(Batrachospermales) is described from Manipur in northeast India. It has a sparsely branched, pseudoparenchymatous thallus with a single, central axial fila- ment that lacks cortical filaments. Spermatangia occur generally in isolated, low and indistinct patches or form an almost continuous ring around the axis. Carposporophytes project into the hollow thallus cavity without an ostiole. The most striking morphological feature is the carposporophyte with very short gonimoblast filaments having cylindrical, nar- row and sparsely branched sterile filaments, the terminal cell of each branch with a single, large, elongate carpospore. The widely distributed L. fluviatilis has spherical carpospores in long branched chains. Phylogenetic analysis of rbcL sequence data and comparison with other Batrachospermales clearly show that our specimens do not align with other species of Lemanea and Paralemanea investigated thus far. Five specific names attributed in previous literature (1973- 2014) to Lemanea from Manipur, L. australis, L. catenata, L. fluviatilis, L.

B, 37(4), pp. 169–174, December 22, 2011 First Record of Compsopogon caeruleus (Balbis ex C.Agardh) Montagne (Compsopogonophyceae, Rhodophyta) from Ogasawara Islands, Japan Taiju Kitayama Department of Botany, National Museum of Nature and Science, 4–1–1 Amakubo, Tsukuba, Ibaraki 305–0005, Japan E-mail: [email protected] (Received 28 August 2011; accepted 28 September 2011) Abstract A benthic freshwater red alga, Compsopogon caeruleus (Balbis ex C.Agardh) Mon- tagne (Compsopogonophyceae, Rhodophyta) was recorded from Ogasawara Islands, Japan, for the first time. This species differs from the other species of the genus Compsopogon, in having cortex of less than three cell-layer, without spinous or curling branchlets, though the size of monosporan- gia is not considered to be a useful taxonomic character in this genus. Finding of C. caeruleus from the extraordinary isolated islands suggested that this alga has any means of dispersion other than flooding of the river’s water (e.g., remnant of marine regression, transportation by migratory birds). Key words : Compsopogon caeruleus, Compsopogonales, Compsopogonophyceae, Ogasawara Islands, red algae. A freshwater red alga referable to Compso- cific epithet is often spelled “coeruleus”, though pogon caeruleus (Balbis ex C.Agardh) Montagne C. Agardh (1824: 122) used “Conferva caerulea” (Compsopogonales, Compsopogonophyceae, (Guiry in Guiry and Guiry, 2006)).

Estimates of nuclear DNA content in red algal lineages. AoB PLANTS 2012: pls005; doi:10.1093/aobpla/pls005 Downloaded from Abstract http://aobpla.oxfordjournals.org/ Background The red algae are an evolutionarily ancient group of predominantly marine organisms with and aims an estimated 6000 species. Consensus higher-level molecular phylogenies support a basal split between the unicellular Cyanidiophytina and morphologically diverse Rhodophytina, the later subphylum containing most red algal species. The Rhodophytina is divided into six classes, of which five represent early diverging lineages of generally uninucleate species, whose evolutionary relationships are poorly resolved. The remaining species compose the large (27 currently recognized orders), morphologically diverse and typically multinucleate Florideophyceae. Nuclear DNA content estimates have been published for ,1 % of the described red algae. The present investigation summarizes the state of our knowledge and at Randall Library, UNC Wilmington on March 22, 2012 expands our coverage of DNA content information from 196 isolates of red algae. Methodology The DNA-localizing fluorochrome DAPI (4′,6-diamidino-2-phenylindole) and RBC (chicken ery- throcytes) standards were used to estimate 2C values with static microspectrophotometry.
