The origin and evolution of green algal and plant actins. (1/989)

The Viridiplantae are subdivided into two groups: the Chlorophyta, which includes the Chlorophyceae, Trebouxiophyceae, Ulvophyceae, and Prasinophyceae; and the Streptophyta, which includes the Charophyceae and all land plants. Within the Streptophyta, the actin genes of the angiosperms diverge nearly simultaneously from each other before the separation of monocots and dicots. Previous evolutionary analyses have provided limited insights into the gene duplications that have produced these complex gene families. We address the origin and diversification of land plant actin genes by studying the phylogeny of actins within the green algae, ferns, and fern allies. Partial genomic sequences or cDNAs encoding actin were characterized from Cosmarium botrytis (Zygnematales), Selaginella apoda (Selaginellales), Anemia phyllitidis (Polypodiales), and Psilotum triquetrum (Psilotales). Selaginella contains at least two actin genes. One sequence (Ac2) diverges within a group of fern sequences that also includes the Psilotum Ac1 actin gene and one gymnosperm sequence (Cycas revoluta Cyc3). This clade is positioned outside of the angiosperm actin gene radiation. The second Selaginella sequence (Ac1) is the sister to all remaining land plant actin sequences, although the internal branches in this portion of the tree are very short. Use of complete actin-coding regions in phylogenetic analyses provides support for the separation of angiosperm actins into two classes. N-terminal "signature" sequence analyses support these groupings. One class (VEG) includes actin genes that are often expressed in vegetative structures. The second class (REP) includes actin genes that trace their ancestry within the vegetative actins and contains members that are largely expressed in reproductive structures. Analysis of intron positions within actin genes shows that sequences from both Selaginella and Cosmarium contain the conserved 20-3, 152-1, and 356-3 introns found in many members of the Streptophyta. In addition, the Cosmarium actin gene contains a novel intron at position 76-1.  (+info)

Two light-activated conductances in the eye of the green alga Volvox carteri. (2/989)

Photoreceptor currents of the multicellular green alga Volvox carteri were analyzed using a dissolver mutant. The photocurrents are restricted to the eyespot region of somatic cells. Photocurrents are detectable from intact cells and excised eyes. The rhodopsin action spectrum suggests that the currents are induced by Volvox rhodopsin. Flash-induced photocurrents are a composition of a fast Ca2+-carried current (PF) and a slower current (PS), which is carried by H+. PF is a high-intensity response that appears with a delay of less than 50 micros after flash. The stimulus-response curve of its initial rise is fit by a single exponential and parallels the rhodopsin bleaching. These two observations suggest that the responsible channel is closely connected to the rhodopsin, both forming a tight complex. At low flash energies PS is dominating. The current delay increases up to 10 ms, and the PS amplitude saturates when only a few percent of the rhodopsin is bleached. The data are in favor of a second signaling system, which includes a signal transducer mediating between rhodopsin and the channel. We present a model of how different modes of signal transduction are accomplished in this alga under different light conditions.  (+info)

The chloroplast infA gene with a functional UUG initiation codon. (3/989)

All chloroplast genes reported so far possess ATG start codons and sometimes GTGs as an exception. Sequence alignments suggested that the chloroplast infA gene encoding initiation factor 1 in the green alga Chlorella vulgaris has TTG as a putative initiation codon. This gene was shown to be transcribed by RT-PCR analysis. The infA mRNA was translated accurately from the UUG codon in a tobacco chloroplast in vitro translation system. Mutation of the UUG codon to AUG increased translation efficiency approximately 300-fold. These results indicate that the UUG is functional for accurate translation initiation of Chlorella infA mRNA but it is an inefficient initiation codon.  (+info)

Cytoplasmic streaming in Chara corallina studied by laser light scattering. (4/989)

An apparatus is described by means of which the power versus frequency spectrum of the photomultiplier current can be obtained for laser light scattered by streaming cytoplasm in the algal cell Chara corallina. A Doppler peak is noted in the spectrum which is abolished when cytoplasmic streaming is arrested by electrical stimulation. For 5 cells of Chara, this simple laser-Doppler velocimeter gave streaming velocities (46-7 mum s-1, S.D. +/- 4-8 at 20 degrees C) similar to those obtained for the same cells using the light microscope (44-3 mum s-1, S.D. +/- 5-3 at 20 degrees C). A narrow distribution of streaming velocities is indicated. The technique described provides a rapid, quantitative assay of the in vivo rheological properties of cytoplasm.  (+info)

Actomyosin contraction of the posterior hemisphere is required for inversion of the Volvox embryo. (5/989)

During inversion of a Volvox embryo, a series of cell shape changes causes the multicellular sheet to bend outward, and propagation of the bend from the anterior to the posterior pole eventually results in an inside-out spherical sheet of cells. We use fluorescent and electron microscopy to study the behavior of the cytoskeleton in cells undergoing shape changes. Microtubules are aligned parallel to the cell's long axis and become elongated in the bend. Myosin and actin filaments are arrayed perinuclearly before inversion. In inversion, actin and myosin are located in a subnuclear position throughout the uninverted region but this localization is gradually lost towards the bend. Actomyosin inhibitors cause enlargement of the embryo. The bend propagation is inhibited halfway and, as a consequence, the posterior hemisphere remains uninverted. The arrested posterior hemisphere will resume and complete inversion even in the presence of an actomyosin inhibitor if the anterior hemisphere is removed microsurgically. We conclude that the principal role of actomyosin in inversion is to cause a compaction of the posterior hemisphere; unless the equatorial diameter of the embryo is reduced in this manner, it is too large to pass through the opening defined by the already-inverted anterior hemisphere.  (+info)

A 210 kDa protein is located in a membrane-microtubule linker at the distal end of mature and nascent basal bodies. (6/989)

A monoclonal antibody raised against purified flagellar basal apparatuses from the green flagellate Spermatozopsis similis reacted with a protein of 210 kDa (p210) in western blots. The protein was partially cloned by immunoscreening of a cDNA library. The sequence encoded a novel protein rich in alanine (25%) and proline (20%), which contained regions similar to proteins of comparable amino acid composition such as extracellular matrix components or the membrane-cytoskeletal linker synapsin. Using a polyclonal antibody (anti-p210) raised against the C-terminal part of p210, it was shown that the protein was highly enriched in the basal apparatuses. Immunogold electron microscopy of isolated cytoskeletons or whole cells revealed that p210 was located in the flagellar transition region. The protein was part of the Y-shaped fibrous linkers between the doublet microtubules and the flagellar membrane, as indicated by statistical analysis of post-labeled sections using anti-centrin and anti-tubulin as controls. In premitotic cells p210 was located in a fibrous layer at the distal end of nascent basal bodies, which was perforated by the outgrowing axoneme. During deflagellation the protein remained at the basal body but we observed changes in its distribution, indicating that p210 partially moved to the tip of the basal body. p210 can be used as a marker to determine basal body position, orientation (parallel or antiparallel) and number in S. similis by indirect immunofluorescence. We suppose that p210 is involved in linking basal bodies to the plasma membrane, which is an important step during ciliogenesis.  (+info)

Group II intron splicing in Escherichia coli: phenotypes of cis-acting mutations resemble splicing defects observed in organelle RNA processing. (7/989)

The mitochondrial group IIB intron rI1, from the green algae Scenedesmus obliquus ' LSUrRNA gene, has been introduced into the lacZ gene encoding beta-galacto-sidase. After DNA-mediated transformation of the recombinant lacZ gene into Escherichia coli, we observed correct splicing of the chimeric precursor RNA in vivo. In contrast to autocatalytic in vitro self-splicing, intron processing in vivo is independent of the growth temperature, suggesting that in E.coli, trans -acting factors are involved in group II intron splicing. Such a system would seem suitable as a model for analyzing intron processing in a prokaryotic host. In order to study further the effect of cis -mutations on intron splicing, different rI1 mutants were analyzed (with respect to their splicing activity) in E.coli. Although the phenotypes of these E. coli intron splicing mutants were identical to those which can be observed during organellar splicing of rI1, they are different to those observed in in vitro self-splicing experiments. Therefore, in both organelles and prokaryotes, it is likely that either similar splicing factors or trans -acting factors exhibiting similar functions are involved in splicing. We speculate that ubiquitous trans -acting factors, via recent horizontal transfer, have contributed to the spread of group II introns.  (+info)

Group II intron splicing in chloroplasts: identificationof mutations determining intron stability and fate of exon RNA. (8/989)

In order to investigate in vivo splicing of group II introns in chloroplasts, we previously have integrated the mitochondrial intron rI1 from the green alga Scenedesmus obliquus into the Chlamydomonas chloroplast tscA gene. This construct allows a functional analysis of conserved intron sequences in vivo, since intron rI1 is correctly spliced in chloroplasts. Using site-directed mutagenesis, deletions of the conserved intron domains V and VI were performed. In another set of experiments, each possible substitution of the strictly conserved first intron nucleotide G1 was generated, as well as each possible single and double mutation of the tertiary base pairing gamma-gamma ' involved in the formation of the intron's tertiary RNA structure. In most cases, the intron mutations showed the same effect on in vivo intron splicing efficiency as they did on the in vitro self-splicing reaction, since catalytic activity is provided by the intron RNA itself. In vivo, all mutations have additional effects on the chimeric tscA -rI1 RNA, most probably due to the role played by trans -acting factors in intron processing. Substitutions of the gamma-gamma ' base pair lead to an accumulation of excised intron RNA, since intron stability is increased. In sharp contrast to autocatalytic splicing, all point mutations result in a complete loss of exon RNA, although the spliced intron accumulates to high levels. Intron degradation and exon ligation only occur in double mutants with restored base pairing between the gamma and gamma' sites. Therefore, we conclude that intron degradation, as well as the ligation of exon-exon molecules, depends on the tertiary intron structure. Furthermore, our data suggest that intron excision proceeds in vivo independent of ligation of exon-exon molecules.  (+info)

Structure of a minimal photosystem I from the green alga Dunaliella salina | Nature PlantsStructure of a minimal photosystem I from the green alga Dunaliella salina | Nature Plants
Solar energy harnessed by oxygenic photosynthesis supports most of the life forms on Earth. In eukaryotes, photosynthesis occurs in chloroplasts and is achieved by membrane-embedded macromolecular complexes that contain core and peripheral antennae with multiple pigments. The structure of photosystem I (PSI) comprises the core and light-harvesting (LHCI) complexes, which together form PSI-LHCI. Here we determined the structure of PSI-LHCI from the salt-tolerant green alga Dunaliella salina using X-ray crystallography and electron cryo-microscopy. Our results reveal a previously undescribed configuration of the PSI core. It is composed of only 7 subunits, compared with 14-16 subunits in plants and the alga Chlamydomonas reinhardtii, and forms the smallest known PSI. The LHCI is poorly conserved at the sequence level and binds to pigments that form new energy pathways, and the interactions between the individual Lhca1-4 proteins are weakened. Overall, the data indicate the PSI of D. salina represents a

BackgroundThe genome of the pico-eukaryotic (bacterial-sized) prasinophyte green alga Ostreococcus lucimarinus has one of the highest gene densities known in eukaryotes, yet it contains many introns. Phylogenetic studies suggest this unusually compact genome (13.2 Mb) is an evolutionarily derived state among prasinophytes. The presence of introns in the highly reduced O. lucimarinus genome appears to be in opposition to simple explanations of genome evolution based on unidirectional tendencies, either neutral or selective. Therefore, patterns of intron retention in this species can potentially provide insights into the forces governing intron evolution.Methodology/Principal FindingsHere we studied intron features and levels of expression in O. lucimarinus using expressed sequence tags (ESTs) to annotate the current genome assembly. ESTs were assembled into unigene clusters that were mapped back to the O. lucimarinus Build 2.0 assembly using BLAST and the level of gene expression was inferred from the

Heat shock protein 90 (Hsp90) is a molecular chaperone highly conserved across the species from prokaryotes to eukaryotes. Hsp90 is essential for cell viability under all growth conditions and is proposed to act as a hub of the signaling network and protein homeostasis of the eukaryotic cells. By interacting with various client proteins, Hsp90 is involved in diverse physiological processes such as signal transduction, cell mobility, heat shock response and osmotic stress response. In this research, we cloned the dshsp90 gene encoding a polypeptide composed of 696 amino acids from the halotolerant unicellular green algae Dunaliella salina. Sequence alignment indicated that DsHsp90 belonged to the cytosolic Hsp90A family. Further biophysical and biochemical studies of the recombinant protein revealed that DsHsp90 possessed ATPase activity and existed as a dimer with similar percentages of secondary structures to those well-studied Hsp90As.

The halotolerant green alga Dunaliella salina accumulates large amounts of beta-carotene when exposed to various stress conditions. Although several studies concerning accumulation and biotechnological production of beta-carotene have been published, the molecular basis and regulation of the genes involved in carotenoid biosynthesis in D. salina are still poorly known. In this paper, we report the isolation and regulation of the lycopene beta-cyclase (Lcy-beta) gene by abiotic stress. The function of this gene was determined by heterologous genetic complementation in E. coli. Gene expression and physiological analyses revealed that D. salina Lcy-beta steady-state transcript and carotenoid levels were up-regulated in response to all stress conditions tested (salt, light and nutrient depletion). The results presented here suggest that nutrient availability is a key factor influencing carotenogenesis as well as carotenoid biosynthesis-related gene expression in D. salina.. ...

Host-derived viral transporter protein for nitrogen uptake in infected marine phytoplanktonHost-derived viral transporter protein for nitrogen uptake in infected marine phytoplankton
Phytoplankton community structure is shaped by both bottom-up factors, such as nutrient availability, and top-down processes, such as predation. Here we show that marine viruses can blur these distinctions, being able to amend how host cells acquire nutrients from their environment while also predating and lysing their algal hosts. Viral genomes often encode genes derived from their host. These genes may allow the virus to manipulate host metabolism to improve viral fitness. We identify in the genome of a phytoplankton virus, which infects the small green alga Ostreococcus tauri, a host-derived ammonium transporter. This gene is transcribed during infection and when expressed in yeast mutants the viral protein is located to the plasma membrane and rescues growth when cultured with ammonium as the sole nitrogen source. We also show that viral infection alters the nature of nitrogen compound uptake of host cells, by both increasing substrate affinity and allowing the host to access diverse ...

Analyses of morphological and ultrastructural characters, and also of the information carried by gene sequences have established that green algae belonging to the class Charophyceae gave rise to the more than 500,000 land plant species currently inhabiting our planet [1, 2]. Charophycean green algae and land plants form the green plant lineage Streptophyta [3], whereas most, if not all, of the other extant green algae belong to the sister lineage Chlorophyta [2]. In contrast to the large diversity of land plants, only a few thousands charophycean species are living today. Six monophyletic groups are currently recognized in the Charophyceae: the Mesostigmatales [4] represented by Mesostigma viride, a scaly biflagellate that has long been thought to be a member of the Prasinophyceae (the earliest-diverging lineage of the Chlorophyta) [5]; the Chlorokybales represented as well by a single species (Chlorokybus atmophyticus); the Klebsormidiales (3 genera, 45 spp.); the Zygnematales (~ 50 genera, ~ ...

We report on a novel arctic strain BM1 of a carotenogenic chlorophyte from a coastal habitat with harsh environmental conditions (wide variations in solar irradiance, temperature, salinity and nutrient availability) identified as Haematococcus pluvialis Flotow. Increased (25‰) salinity exerted no adverse effect on the growth of the green BM1 cells. Under stressful conditions (high light, nitrogen and phosphorus deprivation), green vegetative cells of H. pluvialis BM1 grown in BG11 medium formed non-motile palmelloid cells and, eventually, hematocysts capable of a massive accumulation of the keto-carotenoid astaxanthin with a high nutraceutical and therapeutic potential. Routinely, astaxanthin was accumulated at the level of 4% of the cell dry weight (DW), reaching, under prolonged stress, 5.5% DW. Astaxanthin was predominantly accumulated in the form of mono- and diesters of fatty acids from C16 and C18 families. The palmelloids and hematocysts were characterized by the formation of red-colored

We analyzed the reactive oxygen species (ROS) accumulation in the colony-forming green microalga Botryococcus braunii in response to several stress inducers such as NaCl, NaHCO3, salicylic acid (SA), methyl jasmonate, and acetic acid. A staining assay using the fluorescent dye CellROX Green was used. CellROX Green is a fluorogenic probe used for measuring oxidative stress in live cells. The dye is weakly fluorescent inside cells in a reduced state but exhibits bright green photostable fluorescence upon oxidation by ROS and subsequent binding to DNA. The large amount of liquid hydrocarbons produced and excreted by B. braunii, creates a highly hydrophobic extracellular environment that makes difficult to study short times defense responses on this microalga. The procedure developed here allowed us to detect ROS in this microalga even within a short period of time (in minutes) after treatment of cells with different stress inducers.

There are four stages in the spontaneous generation of Bryopsis sub-protoplasts: aggregation of cell organelles, changes in protoplasmic masses to a spherical shape, primary envelope formation and secondary membrane development. Our data indicate that at least two types of molecules are involved in the aggregation of cell organelles, one acts at an optimum of pH 5-6 and the other on the surfaces of cell organelles acts at an optimum of pH 8-9. This result was surprising because it is contrary to previous results (Pak et al., 1991). Pak et al. suggested that the most effective material for agglutination of cell organelles might be contained in the vacuolar sap and, therefore, the sequential action of vacuolar sap (pH 5-6) and seawater would be very important for the aggregation of cell organelles. They also reported that prompt dilution of extruded algal cell contents with 20 volumes of seawater prevented aggregation. The discrepancy between our results and those of Pak et al. may be due to ...

Known for its antioxidant activity because of its ability to create large amount of carotenoids, it is used in cosmetics and dietary supplements. Few organisms can survive like D. salina does in such highly saline conditions as salt evaporation ponds. To survive, these organisms have high concentrations of β-carotene to protect against the intense light, and high concentrations of glycerol to provide protection against osmotic pressure. This offers an opportunity for commercial biological production of these substances. Dunaliella salina was named by E.C. Teodoresco of Bucharest, Romania after its original discoverer, Michel Felix Dunal, who first scientifically reported sighting the organism in saltern evaporation ponds in Montpellier, France in 1838. He initially named the organism Haematococcus salinus and Protococcus. The organism was fully described as a new, separate genus simultaneously by ...

Saturating pulse fluorescence measurements, well known from studies of higher plants for determination of photosystem II (PS II) characteristics, were applied to cultures of the green alga Dunaliella teitiolecta (Chapter 2). The actual efficiency of PS II (φ PS II ), the maximal efficiency of PS II (F v /F m ), and both photochemical and non- photochemical fluorescence quenching were determined for cultures of D. tertiolecta growing under varying light intensities. The rate of PS II electron flow (J E ) estimated as the product of φ PS II , and the photon flux density (PFD), appeared to correlate well with growth rates determined for the D. tertiolecta cultures . The results indicated that the saturating pulse fluorescence method may be successfully used to determine photosynthetic characteristics of phytoplankton. However, an increase of sensitivity by a factor 1000 was found to be needed for the application of this technique to in situ measurements. Conditions were outlined which have led to ...

Cells of Dunaliella acidophila, an acidophilic and halotolerant green alga, which can grow at pH as high as 2.5 and as low as 0.2 (corresponding to 1.2 M H2SO4) accumulate glycerol when exposed to or grown in medium supplemented with glucose, NaCl, Na2SO4 or H2SO4, The cellular response was not dependent on the type of solute, but only on the solute concentration. When cells were exposed to hypertonic media, synthesis of glycerol commenced at once and continued until a new osmotic equilibrium was established between the cell sap and the medium. Only in hypertonic solution approaching lethal levels was a delay in the glycerol synthesis observed. The transition to hypertonic media showed an initial inhibition of photosynthesis and respiration followed by a full recovery of these activities. The inhibition and the time of recovery were dependent on the extent of hypertonic stress, no significant difference being shown by the solute type. In the same time scale, glycerol synthesis continued up to ...

Author: Rameshprabu Ramaraj, Rungthip Kawaree, Yuwalee Unpaprom. Category: [Download PDF]. Abstract:. Microalgae biodiesel are reported to be better than fossil fuels in terms of life-cycle energy performance. Green alga, Botryococcus braunii symbolizes one of the most favorable resources of biodiesel due to relatively high lipid content. The present study focused on the cultivation of Botryococcus braunii with the fed-batch in 4 L lab-scale continuously stirred tank reactors (CSTRs) through inexpensive red Nile tilapia effluent medium (RNTEM), biomass growth, protein, carbohydrate, lipid, hydrocarbon production and fatty acids profiles. Additionally, in this study we have evaluated the feasibility of biodiesel production directly from B. braunii biomass at laboratory scale achieved through direct transesterification process. B. braunii growth confirmed the highest biomass yield (8.57 g L?1) and 35.32% hydrocarbon content was observed. Further, 47.59% lipids, 16.39% proteins and 38.21% ...

Novel touch-induced, Ca(2+)-dependent phobic response in a flagellate by Georg Kreimer and George B. WitmanNovel touch-induced, Ca(2+)-dependent phobic response in a flagellate by Georg Kreimer and George B. Witman
The biflagellate green alga Spermatozopsis similis exhibits a remarkable avoidance reaction in addition to the photophobic or stop response characteristic of such algae. S. similis normally swims forward with its anteriorly attached flagella directed posteriorly and propagating sine-like waves base to tip. Upon contact with surfaces or other cells, S. similis responds with rapid backward swimming, covering distances of up to 50 microns in 140 to 220 msec. This reaction, which we term the mechanoshock response, also can be triggered by vigorous mechanical stimulation, but not by physiological light intensities. It consists of 3 phases: (1) a rapid acceleration phase with average duration of 31 msec; (2) a phase of about 66 msec with constant high speed (maximal velocities of | 600 microns.sec-1) or slow deceleration; and (3) a deceleration phase of approximately 83 msec, followed by a stop or short period of circling. The cells then resume forward swimming in a random direction. Prior to the mechanoshock

The global explosion of eukaryotic algae: The potential role of phosphorus?The global explosion of eukaryotic algae: The potential role of phosphorus?
There arose one of the most important ecological transitions in Earths history approximately 750 million years ago during the middle Neoproterozoic Era (1000 to 541 million years ago, Ma). Biomarker evidence suggests that around this time there was a rapid shift from a predominantly bacterial-dominated world to more complex ecosystems governed by eukaryotic primary productivity. The resulting Rise of the algae led to dramatically altered food webs that were much more efficient in terms of nutrient and energy transfer. Yet, what triggered this ecological shift? In this study we examined the theory that it was the alleviation of phosphorus (P) deficiency that gave eukaryotic alga the prime opportunity to flourish. We performed laboratory experiments on the cyanobacterium Synechocystis salina and the eukaryotic algae Tetraselmis suecica and examined their ability to compete for phosphorus. Both these organisms co-occur in modern European coastal waters and are not known to have any allelopathic

Volvox colonies. Microscope footage of Volvox sp. colonies. Volvox are small freshwater unicellular green algae that usually make up larger spherical colonies, which behave like a multicellular organisms. Individual cells are connected to each other via protoplasmic strands, and embedded in a globe of glycoprotein. Daughter colonies (small green spheres) are produced asexually inside each parent colony, which disintegrates to release them when they are mature. Colonies also reproduce sexually, in which case male and female gametes are produced and a sexual union occurs. Individual Volvox cells have two hair-like flagella that protrude outwards and are used for colony locomotion. - Stock Video Clip K005/4089

Algaes enzyme might hold the secret to mass producing biofuel | EngadgetAlgaes enzyme might hold the secret to mass producing biofuel | Engadget
A common microscopic pond and lake alga named Botryococcus braunii makes big amounts of liquid hydrocarbons that can be used to make biofuel. Problem is, we cant use the organism itself as a source, because it grows very slowly. A group of scientists from Texas A&M AgriLife Research, however, is looking into what genes are responsible for producing its enzyme that initiates the production of oil. See, the group wants to replicate its ability to make big amounts of oil in other plants more suitable for mass production. And they think the key is to express the enzymes associated genes in those other organisms, such as faster-growing algae.

Sandwalk: Is lateral gene transfer (LGT) Lamarckian?Sandwalk: Is lateral gene transfer (LGT) Lamarckian?
Regarding mechanisms. In the Leger et al. paper we cite many papers that discuss potential mechanisms in detail (inter-kingdom conjugation, viral transduction, gene transfer from endosymbionts). If one still finds it hard to believe that genes can get moved around between eukaryote genomes, then consider the rate of discovery of new eukaryotic viruses lately -- it is likely that we have only found the tip of the iceberg. Consider for example, a recently described giant virus in the green alga Tetraselmis (Schvarcz CR and Steward GF (2018) A giant virus infecting green algae encodes key fermentation genes. Virology 518:423-433). Two of the host-derived genes encoded in this virus are in fact involved in anaerobic pyruvate metabolism (pyruvate formate lyase and its activating enzyme). These are the same genes as found in anaerobic protists functioning in their mitochondria (see Stairs et al (2011) Mol. Biol. Evol. 28:2087-99 or Müller et al. (2012)). Couple this observation with the findings of ...

More on Gonium from Erik HanschenMore on Gonium from Erik Hanschen
Sex and the evolution of multicellularity are pretty tightly entwined in the volvocine algae- many aspects of sex, anisogamy, oogamy, internal/external fertilization, anisogamy ration, all correlate with size. On the molecular side, RB has moved into the mating locus of Gonium and Volvox, and Volvox has male/female specific alleles. Now, we dont know all the specific details- if moving into the mating locus and evolving male/female specific alleles in Volvox are a cause of increasing morphological complexity, or rather a consequence of being in non-recombining regions. The Volvox mating type locus showed there are differences in RB intron splicing both between male/female alleles and asexual/sexual expression, suggesting that RB is playing different roles in males and females and involved in sexual development. If RB is playing a role in sexual development, theres strong selection pressure to end up in the mating type locus, which is why RB moving into the mating locus is interesting. But this ...

Why Blue Green Algae Makes Me Tired. Actually, the algae isnt tiring me. Im tired of the people trying to sell it to me.

Algal MIPs, high diversity and conserved motifs | BMC Evolutionary Biology | Full TextAlgal MIPs, high diversity and conserved motifs | BMC Evolutionary Biology | Full Text
The algal PIPs show many similarities with the PIPs of land plants and it is tempting to make the assumption that PIPs, with those shared features, were present already some 1000 MYA at the split of the chlorophytes and the streptophytes [10-12]. Land plant PIPs are known to be regulated by pH, Ca2+ and phosphorylation and a molecular gating mechanism has been suggested. In this, several of the residues have overlapping functions in controlling the D-loop conformation in response to the different signals. However, the evolution of the gating mechanism is likely to have been a stepwise process, starting out from a primitive regulatory mechanism and then sequentially adding further functionality. The presence of an among all PIPs conserved histidine crucial for pH gating [H193 in SoPIP2;1; 20, 21] in the algal PIPs, implies that this regulatory feature might be such a primitive mechanism. Contrary to this, the acidic amino acid residues responsible for Ca2+ binding (D28 and E31 in SoPIP2;1) are ...

Essay on Algae : Top 21 Essays on AlgaeEssay on Algae : Top 21 Essays on Algae
Sexual reproduction is one of the means of perpetuation of species in algae with ultimate increase in the population of the individuals. The process involves the fusion of two gametes or sex cells which may originate from the same thallus (monoecious) or from different thalli (dioecious). The gametes may he flagellate or non-flagellate. In algae, the mode of sexual reproduction ranges from isogamy, anisogamy to oogamy. In general, sexual reproduction takes place after the alga had attained a certain amount of vegetative growth and having certain amount of reserve food built up. In algae, an isogamous fusion of two zoogametes is the most primitive type of sexual reproduction. The evolutionary tendency is isogamy, anisogamy to oogamy. Anisogamy is an advanced condition than isogamy. Among anisogamy again there are two condi-tions prevailing: (i) both the fusing pair of gametes may be flagellate, and (ii) the larger one is non-flagellate as against the smaller which is flagellate. It is evident ...

Volvox 2015: taxonomy, phylogeny & ecologyVolvox 2015: taxonomy, phylogeny & ecology
The worst-kept secret among Volvox researchers is that the current volvocine taxonomy is a train wreck. Within the largest family, the Volvocaceae, five nominal genera are polyphyletic (Pandorina, Volvulina, Eudorina, Pleodorina, and Volvox). Of the remaining three, two are monotypic (Platydorina and Yamagishiella). Only the newly described Colemanosphaera is monophyletic with more than one species. The extent of the problem was suspected long before it was confirmed by molecular phylogenetics, and ad hoc attempts to deal with it have led to the existence of such taxonomic abominations as sections, formas, and syngens. An overhaul is called for, but it is complicated by the aforementioned loss of type cultures.. Even species-level taxonomy is often questionable, since a lot of the older descriptions were based entirely on morphological traits, which we know are often convergent. The opposite problem occurs, too. Hisayoshi Nozaki described fixed differences between Volvox strains collected ...

For a sustainable production platform, the algae cultivation should be integrated with downstream processes. Ideally the algae are not harvested, but the product is isolated while cultivation and growth is continued especially if the doubling time is slow. Consequently, hydrocarbons can be extracted while keeping the algae viable.

Folding and misfolding in a naturally occurring circularly permuted PDZ domainFolding and misfolding in a naturally occurring circularly permuted PDZ domain
One of the most extreme and fascinating examples of naturally occurring mutagenesis is represented by circular permutation. Circular permutations involve the linking of two chain ends and cleavage at another site. Here we report the first description of the folding mechanism of a naturally occurring circularly permuted protein, a PDZ domain from the green alga Scenedesmus obliquus. Data reveal that the folding of the permuted protein is characterized by the presence of a low energy off-pathway kinetic trap. This finding contrasts with what was previously observed for canonical PDZ domains that, although displaying a similar primary structure when structurally re-aligned, fold via an on-pathway productive intermediate. Although circular permutation of PDZ domains may be necessary for a correct orientation of their functional sites in multi-domain protein scaffolds, such structural rearrangement may compromise their folding pathway. This study provides a straightforward example of the divergent ...

The sex-inducer of the spherical green alga Volvox carteri is one of the most potent biological effector molecules known: it is released into the medium by sexual males and triggers the switch to the sexual cleavage program in the reproductive cells of vegetatively grown males and females even at concentrations as low as 10 (-16) M. In an adult Volvox alga, all cells are embedded in an extensive extracellular matrix (ECM), which constitutes >99% of the volume of the spheroid. There exist no cytoplasmic connections between the cells in an adult alga, so any signal transduction between different cells or from the organisms environment to a reproductive cell must involve the ECM. Recently, a small cysteine-rich extracellular protein, VCRP, was identified in Volvox and shown to be quickly synthesized by somatic cells in response to the sex-inducer. Due to its characteristics, VCRP was speculated to be an extracellular second messenger from somatic cells to reproductive cells. Here a related ...

Haematococcus pluvialis is the best source of natural astaxanthin, known as the king of antioxidants. H. pluvialis have four cell forms: spore, motile cell, non-motile cell and akinete. Spores and motile cells are susceptible to photoinhibition and would die under photoinduction conditions. Photoinduction using non-motile cells as seeds could result in a higher astaxanthin production than that using akinetes. However, the mechanism of this phenomenon has not been clarified. Transcriptome was sequenced and annotated to illustrate the mechanism of this phenomenon. All differentially expressed genes involved in astaxanthin biosynthesis were up-regulated. Particularly, chyb gene was up-regulated by 16-fold, improving the conversion of β-carotene into astaxanthin. Pyruvate was the precursor of carotenoids biosynthesis. Pyruvate kinase gene expression level was increased by 2.0-fold at the early stage of akinetes formation. More changes of gene transcription occurred at the early stage of akinetes formation,

Biodiesel or ethanol derived from lipids or starch produced by microalgae may overcome many of the sustainability challenges previously ascribed to petroleum-based fuels and first generation plant-based biofuels. The paucity of microalgae genome sequences, however, limits gene-based biofuel feedstock optimization studies. Here we describe the sequencing and de novo transcriptome assembly for the non-model microalgae species, Dunaliella tertiolecta, and identify pathways and genes of importance related to biofuel production. Next generation DNA pyrosequencing technology applied to D. tertiolecta transcripts produced 1,363,336 high quality reads with an average length of 400 bases. Following quality and size trimming, ~ 45% of the high quality reads were assembled into 33,307 isotigs with a 31-fold coverage and 376,482 singletons. Assembled sequences and singletons were subjected to BLAST similarity searches and annotated with Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) orthology

Amputated apices from vegetative wildtype cells of the uninucleate green alga Acetabularia acetabulum can differentiate a reproductive structure of cap in the absence of the nucleus (Hammerling, J. (1932) Biologisches Zentralblatt 52, 42-61). To define the limits of the ability of wildtype cells to control reproductive differentiation, we determined when during development apices from wildtype cells first acquired the ability to make a cap in the absence of the nucleus and, conversely, when cells with a nucleus lost the ability to recover from the loss of their apices. To see when the apex acquired the ability to make a cap without the nucleus, we removed apices from cells varying either the developmental age of the cells or the cellular volume left with the apex. Cells must have attained the adult phase of development before the enucleate apex could survive amputation and make a cap. Apices removed from cells early in adult growth required more cell volume to make a cap without the nucleus ...

The extracellular matrix (ECM) of Volvox is modified during development or in response to external stimuli, like the sex-inducing pheromone. It has recently been demonstrated that a number of genes triggered by the sex-inducing pheromone are also inducible by wounding. By differential screening of a cDNA library, a novel gene was identified that is transcribed in response to the pheromone. Its gene product was characterized as an ECM glycoprotein with a striking feature: it exhibits a hydroxyproline content of 68% and therefore is an extreme member of the family of hydroxyproline-rich glycoproteins (HRGPs). HRGPs are known as constituents of higher plant ECMs and seem to function as structural barriers in defense responses. The Volvox HRGP is also found to be inducible by wounding. This indicates that the wound response scenarios of higher plants and multicellular green algae may be evolutionary related ...

Volvox carteri - microbewikiVolvox carteri - microbewiki
A notable structural feature of Volvox carteri is the formation of microscopic cytoplasmic bridges between somatic cells of the colonies, originating from incomplete cell division during cytokinesis.[1] These connections, which can only be seen by using electron microscopy, form a hexagonal pattern in the extracellular matrix and allows the movement of small organelles such as mitochondria between cells.[10] As the cells of a colony move further apart, the strands become stretched and therefore smaller, allowing only ribosomes and endoplasmic reticulum to be exchanged among cells.[3] The ability to transport information between cells allows V. carteri to synchronize its flagellate movements and reproductive actions.[1][3] This unique quality of cells interacting with one another in order to benefit the parent colony is similar to the actions of a highly developed multicellular organism.[1] Volvox carteri is classified as a species of green algae and therefore obtains its energy through ...

Micromonas strains of small prasinophyte green algae are found throughout the worlds oceans, exploiting widely different niches. We grew arctic and temperate strains of Micromonas and compared their susceptibilities to photoinactivation of Photosystem II, their counteracting Photosystem II repair capacities, their Photosystem II content, and their induction and relaxation of non-photochemical quenching. In the arctic strain Micromonas NCMA 2099, the cellular content of active Photosystem II represents only about 50 % of total Photosystem II protein, as a slow rate constant for clearance of PsbA protein limits instantaneous repair. In contrast, the temperate strain NCMA 1646 shows a faster clearance of PsbA protein which allows it to maintain active Photosystem II content equivalent to total Photosystem II protein. Under growth at 2 A degrees C, the arctic Micromonas maintains a constitutive induction of xanthophyll deepoxidation, shown by second-derivative whole-cell spectra, which supports ...

Nitrogen starvation and limitation are known to induce important physiological changes especially in lipid metabolism of microalgae (triglycerides, membrane lipids, beta-carotene, etc.). Although little information is available for Dunaliella salina, it is a promising microalga for biofuel production and biotechnological applications due to its ability to accumulate lipid together with beta-carotene. Batch and chemostat experiments with various degrees of nitrogen limitation, ranging from starvation to nitrogen-replete conditions, were carried out to study carbon storage dynamics (total carbon, lipids, and beta-carotene) in steady state cultures of D. salina. A new protocol was developed in order to manage the very high beta-carotene concentrations and to more accurately separate and quantify beta-carotene and triglycerides by chromatography. Biomass evolution was appropriately described by the Droop model on the basis of the nitrogen quota dynamics. Triglycerides and beta-carotene were both strongly

The production of biofuels from microalgae is a promising and sustainable alternative. Its production is determined by the content of lipids and carbohydrates, which is different for each microalgae species and is affected by environmental factors, being lighting one of the principal determining their biochemical composition. The colour temperature (electromagnetic radiation and light spectrum) is a determining factor for the production of lipids and carbohydrates in microalgae. The aim of this assay was to evaluate the effect of three colour temperatures (6500, 10,000 and 20,000 °K) on the biomass (cel mL−1), biomass production and productivity (g L−1 and g L−1 day−1), lipid and carbohydrate content (%), lipid and carbohydrate production and productivity (mg L−1 and mg L−1 day−1), composition and content of fatty acids (%) in two microalgae species: Dunaliella salina and Nannochloropsis oculata.

Photoperiods have an important impact on macroalgae living in the intertidal zone. Ocean acidification also influences the physiology of macroalgae. However, little is known about the interaction between ocean acidification and photoperiod on macroalgae. In this study, a green alga Ulva linza was cultured under three different photoperiods (L: D = 8:16, 12:12, 16:8) and two different CO2 levels (LC, 400 ppm; HC, 1,000 ppm) to investigate their responses. The results showed that relative growth rate of U. linza increased with extended light periods under LC but decreased at HC when exposed to the longest light period of 16 h compared to 12 h. Higher CO2 levels enhanced the relative growth rate at a L: D of 8:16, had no effect at 12:12 but reduced RGR at 16:8. At LC, the L: D of 16:8 significantly stimulated maximum quantum yield (Yield). Higher CO2 levels enhanced Yield at L: D of 12:12 and 8:16, had negative effect at 16:8. Non-photochemical quenching (NPQ) increased with increasing light period. High

Massive Trentepohlia-Bloom in a Glacier Valley of Mt. Gongga, China, and a New Variety of Trentepohlia (Chlorophyta)Massive Trentepohlia-Bloom in a Glacier Valley of Mt. Gongga, China, and a New Variety of Trentepohlia (Chlorophyta)
Trentepohlia is a genus of subaerial green algae which is widespread in tropical, subtropical, and also temperate regions with humid climates. For many years, small-scale Trentepohlia coverage had been found on the rocks of some glacier valleys on the northern slopes of Mt. Gongga, China. However, since 2005, in the Yajiageng river valley, most of the rocks are covered with deep red coloured algal carpets, which now form a spectacular sight and a tourist attraction known as Red-Stone-Valley. Based on morphology and molecular data, we have named this alga as a new variety: Trentepohlia jolithus var. yajiagengensis var. nov., it differs from the type variety in that its end cells of the main filament are often rhizoid, unilateral branches. This new variety only grows on the native rock, both global warming and human activity have provided massive areas of suitable substrata: the rocks surfaces of the Yajiageng river valley floodplain were re-exposed because of heavy debris flows in the summer of 2005;
