Classification of loops of lampbrush chromosomes according to the arrangement of transcriptional complexes. (1/41)

The arrangement of transcriptional units in the loops of lampbrush chromosomes from oocyte nuclei of urodele amphibia and from primary nuclei of the green alga Acetabularia have been studied in the electron microscope using spread preparations. Loops with different patterns of arrangement of matrix units (i.e. to a first approximation, transcriptional units) can be distinguished: (i) loops consisting of one active transcriptional unit; (ii) loops containing one active transcriptional unit plus additional fibril-free, i.e. apparently untranscribed, intercepts that may include 'spacer' regions; (iii) loops containing two or more transcriptional units arranged in identical or changing polarities, with or without interspersed apparent spacer regions. Morphological details of the transcriptional complexes are described. The observations are not compatible with the concept that one loop reflects one and only one transcriptional unit but, rather, lead to a classification of loop types according to the arrangement of their transcriptional units. We propose that the lampbrush chromosome loop can represent a unit for the coordinate transcription of either one gene or a set of several (different) genes.  (+info)

Temperature dependence of cycloheximide-sensitive phase of circadian cycle in Acetabularia mediterranea. (2/41)

The biochemical nature of the circadian regulatory system that controls many cellular activities is still unclear. Recent results obtained from the application of protein synthesis inhibitors to individual Acetabularia cells expressing circadian rhythms of photosynthesis indicate that some protein(s) must be synthesized on 80S ribosomes during a discrete part of each cycle to insure correct time-keeping. A comparative study of the effects of brief cycloheximide treatments on cells investigated at different temperature has revealed that the phase of cycloheximide sensitivity is 4-6 hr longer and occurs about 8 hr later in the cycle when cells are kept at 20 degrees rather than 25 degrees. Temperature is known to influence the function of the circadian regulatory system in Acetabularia, but the effect on frequency is small (Q10 approximately equal to 0.8) due to the existence of a temperature-compensating feature. The large effects of temperature observed here thus favor the interpretation that protein synthesis on 80S ribosomes, while providing an essential component of the circadian timing mechanism, does not itself generate the period of the photosynthesis rhythm.  (+info)

Whorl morphogenesis in the dasycladalean algae: the pattern formation viewpoint. (3/41)

The dasycladalean algae produce diverse whorled structures, among which the best known are the vegetative and reproductive whorls of Acetabularia acetabulum. In this paper, we review the literature pertaining to the origin of these structures. The question is addressed in terms of the necessary pattern-forming events and the possible mechanisms involved, an outlook we call the pattern formation viewpoint. The pattern-forming events involved in the morphogenesis of the vegetative and reproductive whorls of Acetabularia have been used to define five and six morphogenetic stages, respectively. We discuss three published mechanisms which account, at least in part, for the pattern-forming events. The mechanisms are mechanical buckling of the cell wall, reaction-diffusion of morphogen molecules along the cell membrane, and mechanochemical interactions between Ca2+ ions and the cytoskeleton in the cytosol. The numerous differences between these mechanisms provide experimental grounds to test their validity. To date, the results of these experiments point towards reaction diffusion as the most likely patterning mechanism. Finally, we consider the evolutionary origin of the vegetative and reproductive whorls and provide mechanistic explanations for some of the major evolutionary advances.  (+info)

Cytoplasmic induction of changes in the ultrastructure of the Acetabularia nucleus and perinuclear cytoplasm. (4/41)

The ultrasturcture of the cell nucleus and perinuclear cytoplasm in Acetabularia is quite different in young and old cells. When a nucleus of an old cell was implanted into the cytoplasm of a young cell the nucleus assumed the morphology typical of a young cell within less than 10 days. The cytoplasm of an old cell was able to induce the reverse change in an implanted nucleus from a young cell. This cytoplasmic induction of nuclear ageing appeared to proceed more rapidly than rejuvenation.  (+info)

Asymmetric subcellular mRNA distribution correlates with carbonic anhydrase activity in Acetabularia acetabulum. (5/41)

The unicellular green macroalga Acetabularia acetabulum L. Silva is an excellent system for studying regional differentiation within a single cell. In late adults, physiologically mediated extracellular alkalinity varies along the long axis of the alga with extracellular pH more alkaline along the apical and middle regions of the stalk than at and near the rhizoid. Respiration also varies with greater respiration at and near the rhizoid than along the stalk. We hypothesized that the apical and middle regions of the stalk require greater carbonic anhydrase (CA) activity to facilitate inorganic carbon uptake for photosynthesis. Treatment of algae with the CA inhibitors acetazolamide and ethoxyzolamide decreased photosynthetic oxygen evolution along the stalk but not at the rhizoid, indicating that CA facilitates inorganic carbon uptake in the apical portions of the alga. To examine the distribution of enzymatic activity within the alga, individuals were dissected into apical, middle, and basal tissue pools and assayed for both total and external CA activity. CA activity was greatest in the apical portions. We cloned two CA genes (AaCA1 and AaCA2). Northern analysis demonstrated that both genes are expressed throughout much of the life cycle of A. acetabulum. AaCA1 mRNA first appears in early adults. AaCA2 mRNA appears in juveniles. The AaCA1 and AaCA2 mRNAs are distributed asymmetrically in late adults with highest levels of each in the apical portion of the alga. mRNA localization and enzyme activity patterns correlate for AaCA1 and AaCA2, indicating that mRNA localization is one mechanism underlying regional differentiation in A. acetabulum.  (+info)

The circadian rhythm in photosynthesis in Acetabularia in the presence of actinomycin D, puromycin, and chloramphenicol. (6/41)

Anucleate Acetabularia crenulata shows a circadian rhythm in photosynthesis. In this study, an oxygen electrode was employed to measure this photosynthetic rhythm in the presence and absence of the inhibitors, actinomycin D, chloramphenicol, and puromycin. High concentrations of the inhibitors were used: actinomycin D, 20-40 micrograms ml-1; puromycin, 30 and 100 micrograms ml-1; and chloramphenicol, 250 micrograms ml-1. The effectiveness of these inhibitors on protein synthesis was also measured under the same conditions used for the determination of rhythmicity. In spite of large effects of all three inhibitors on the incorporation of 14C leucine, no effect on the period or the phase of the photosynthetic rhythm was observed. The higher concentration of puromycin and chloramphenicol produced toxic effects which were expressed as a reduction in the amount of photosynthesis, but rhythmicity was still apparent. After 3 or 4 days' exposure to actinomycin, Acetabularia became resistant to its effect. Recovery was also observed in the ability to incorporate leucine. The implications of these results for theories of the basic oscillator responsible for circadian rhythmicity are discussed.  (+info)

Growth of the nuclear envelope in the vegetative phase of the green alga Acetabularia. Evidence for assembly from membrane components synthesized in the cytoplasm. (7/41)

The primary nucleus of the green alga Acetabularia grows about 25,000-fold in volume while it is separated from the endoplasmic reticulum and the whole cytoplasm by a special paranuclear cisterna of a vacuolar labyrinthum system which shows only very few (two to six per square micrometer) and small (ca. 40-120 nm in diamter) fenestrations. The nuclear envelope does not bear polyribosomes, nor do they occur in the entire zone intermediate between the nuclear envelope and the paranuclear cisterna. It is suggested that this special form of nuclear envelope growth takes place by assembly from cytoplasmically synthesized proteins that are translocated across the paranuclear cisterna in a nonmembrane-structured form.  (+info)

Expression of V-ATPase proteolipid subunit of Acetabularia acetabulum in a VMA3-deficient strain of Saccharomyces cerevisiae and its complementation study. (8/41)

The function of the translation products of six different cDNAs for Acetabularia V-ATPase proteolipid subunit (AACEVAPD1 to AACEVAPD6) was examined using a Saccharomyces cerevisiae VMA3-deficient strain that lacked its own gene for one of the proteolipid subunits of V-ATPase. Expression of the cDNAs in the strain revealed that four cDNAs from the six complemented the proton transport activity into the vacuole, visualized by fluorescence microscopy. The vacuolar-membrane-enriched fractions from the four transformants showed cross-reactivity with antibodies against the subunits a and A of S. cerevisiae V-ATPase. Two translation products from the other two cDNAs were demonstrated not to be localized in vacuolar membranes, and thus could not complement the function of the VMA3-deficient strain. As the primary structures deduced from the former four cDNAs are similar but clearly different from those of the latter two, the latter two translation products may not be able to substitute for theVMA3 gene product.  (+info)

Acetabularia is a genus of green algae, specifically of the Polyphysaceae family, Typically found in subtropical waters, Acetabularia is a single-celled organism, but gigantic in size and complex in form, making it an excellent model organism for studying cell biology. In form, the mature Acetabularia resembles the round leaves of a nasturtium, is 0.5 to 10 cm tall and has three anatomical parts: a bottom rhizoid that resembles a set of short roots; a long stalk in the middle; and a top umbrella of branches that may fuse into a cap. The single nucleus of Acetabularia is located in the rhizoid, and allows the cell to regenerate completely if its cap is removed. The caps of two Acetabularia may also be exchanged, even from two different species.[citation needed] In addition, if a piece of the stem is removed, with no access to the nucleus in the rhizoid, this isolated stem piece will also grow a new cap. In the 1930s-1950s Joachim Hämmerling conducted experiments in which he demonstrated ...
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 ...

Dr. Joachim Hämmerling ForMemRS (9 March 1901 - 5 August 1980) was a pioneering Danish-German biologist funded by Nazi Germany who determined that the nucleus of a cell controls the development of organisms. His experimentation with the green algae Acetabularia provided a model subject for modern cell biological research, and proved the existence of morphogenetic substances, or mRNP. Joachim August Wilhelm Hämmerling was born on 9 March 1901 in Berlin. He was educated at the University of Berlin and University of Marburg. He received his doctorate in 1924. From 1924 to 1931 he was a research assistant at the Kaiser Wilhelm Institute for Biology, and from 1931 to 1940 a lecturer. In 1940 he became Director of the German-Italian Institute of Marine Biology. In 1942 he became an associate professor of marine biology at the University of Berlin, before becoming the head of the Kaiser Wilhelm Institute for Biology in Langenargen am Bodensee in 1946. From 1949-1970 he served as the Director of the ...
The ultrastructure of twO kinds of transcription ally active chromatin, the lampbrush chromosome loops and the nucleoli from amphibian oocytes and primary nuclei of the green alga Acetabularia, has been examined after manual isolation and dispersion in low salt media of slightly alkaline pH using various electron microscopic staining techniques (positive staining, metal shadowing, negative staining, preparation on positively charged films, etc.) and compared with the appearance of chromatin from various somatic cells (hen erythrocytes, rat hepatocytes, ClIltured murine sarcoma cells) prepared in parallel. While typical nucleosomes were revealed with all the techniques for chromatin from the latter three cell system, no nucleosomes were identified in either the lampbrush chromosome structures or the nucleolar chromatin. Nucleosomal arrays were absent not only in maximally fibril-covered matrix units but also in fibril-free regions between transcriptional complexes, including the apparent spacer ...
As an undergraduate, I was fascinated by the realisation that all cells have the same set of genes yet do such different things to generate a functioning organism. I wanted to understand where the programme for development is encoded. At that time, the place where I was studying - the University of Sussex - was a hotbed of evolutionary biologists, geneticists and developmental biologists, so it was the right place to be thinking about these questions. For my PhD I chose to stay at Sussex to work under Brian Goodwin, originally a physicist who did his PhD with the great C. H. Waddington and was one of the pioneers in theoretical biology. I dreamt that it should be possible to master a combination of theory and experiment side by side to understand the rules that govern development. Brians lab had a mixture of people studying a variety of processes in many different systems: aggregation of the slime mould Dictyostelium, regeneration in the unicellular plant Acetabularia and of the limbs of ...

You can do the math. Lets think optimum conditions for SWD development. A single female can lay around 350 eggs during her lifetime, about 15 per day. The egg to adult phase of the life cycle takes as little as 6 days. So, one female in one day can result in 15 more adults 6 days later, and, during those 6 days, she will have laid another 90 eggs. 6 days after that, those 90 eggs will all be adults. Half of the 105 adults will be females, capable of laying ~350 eggs during their lifetimes...thats 18,375 eggs. A typical life span for SWD is 3 to 9 weeks and there are estimated to be about 10 generations per year in the US, depending on climate.. ...

Plants in the juvenile phase of growth generally are easier to propagate vegetatively than plants that have reached the adult phase (Preece, 2002). Cuttings taken from adult shoots of plants can be rooted, but the frequency of success is low, especially with woody plants. Likewise, researchers have had great challenges when attempting to micropropagate adult forms of many woody species. In fact, the change from the juvenile to adult phase is considered to be the most serious constraint to rooting cuttings (Howard, 1990) and micropropagation of shrubs and trees. Most of the difficulty experienced in rooting mature shoots seems to be caused by their altered physiology, but can also be related to greater contamination with microorganisms and viruses than with juvenile forms.. Juvenile explants are usually most readily established in vitro, grow and proliferate at a more rapid rate, and are more rootable than adult material. This is especially true with tree species where mlcropropagatlon of adult ...
The Lyb-2 cell-surface alloantigens of the mouse are selectively and perhaps exclusively expressed in the B lymphocyte lineage, but not on antibody- forming cells. Thus if the Lyb-2 molecule is concerned in specific B cell function, it must participate in the generative phase of the antibody response. Accordingly, monoclonal Lyb-2 antibody was found to depress the plaque- forming cell (PFC) response to sheep erythrocytes in 5-d Mishell-Dutton assays when added within the first 3 d of culture, but not later. The rate of PFC generation was not affected, signifying an absolute reduction in the number of PFC generated. Because reduction of PFC counts by Lyb-2 antibody was not affected by exclusion of Lyt-2(+) T cells, it is unlikely that the reduction depends on augmented suppression by T cells. Augmented B cell- mediated suppression is also unlikely, because the PFC response of serial combinations of congenic Lyb-2.1 and Lyb-2.2 cells, in the presence of monoclonal Lyb-2.1 antibody, was reduced ...

The ability of adolescents to access safe and effective new products for HIV prevention and treatment is optimised by adolescent licensure at the same time these products are approved and marketed for adults. Many adolescent product development programmes for HIV prevention or treatment products may proceed simultaneously with adult phase III development programmes. Appropriately implemented, this strategy is not expected to delay licensure as information regarding product efficacy can often be extrapolated from adults to adolescents, and pharmacokinetic properties of drugs in adolescents are expected to be similar to those in adults. Finally, adolescents enrolled in therapeutic HIV prevention and treatment research can be considered adults, based on US Food and Drug Administration (FDA) regulations and the appropriate application of state law. The FDA permits local jurisdictions to apply state and local HIV/sexually transmitted infection minor treatment laws so that adolescents who are ...

Novel glycine oxidase (GlyOX) from Marinomonas mediterranea depends on cysteine tryptophilquinone (CTQ) and catalyzes the oxidative deamination of glycine to produce a glyoxylate, ammonia, and hydrogen peroxide. M. mediterranea GlyOX genes (goxA and goxB) were cloned and recombinant GlyOX was heterologously expressed by E. coli. The purification of recombinant GlyOX was carried out by metal affinity and DEAE-Toyopearl 650M column chromatographies. M. mediterranea GlyOX was homotetramic with a molecular mass of 76kDa and showed optimum activity around 30°C and at pH 5.0, and stability below 50°C and between pH 5.0 to 9.0. M. mediterranea GlyOX shows a strict substrate specificity toward glycine, and the Michaelis constant for glycine was 0.5mM. M. mediterranea GlyOX could determine the quantity of glycine in human serum and human blood plasma with high sensitivity. This study revealed the catalytic and structural properties of M. mediterranea GlyOX with high substrate specificity. ...
Abscisic acid (ABA) has been implicated as a key component in water-deficit-induced responses, including those triggered by drought, NaCl, and low- temperature stress. In this study a role for ABA in mediating the NaCl-stress-induced increases in tonoplast H1-translocating ATPase (V-ATPase) and Na1/H1 antiport activity in Mesembryanthemum crystallinum, leading to vacuolar Na1 sequestration, were investigated. NaCl or ABA treatment of adult M. crystallinum plants induced V-ATPase H1 transport activity, and when applied in combination, an additive effect on V-ATPase stimulation was observed. In contrast, treatment of juvenile plants with ABA did not induce V-ATPase activity, whereas NaCl treatment resulted in a similar response to that observed in adult plants. Na1/H1 antiport activity was induced in both juvenile and adult plants by NaCl, but ABA had no effect at either developmental stage. Results indicate that ABA-induced changes in V-ATPase activity are dependent on the plant reaching its adult phase,
The life cycle of a honey bee is broken down into three different stages. The three stages are the larval, pupal and adult phases. The queen bee is the only egg laying bee in an entire hive. She can lay either fertilized or unfertilized eggs. Fertilized eggs become either worker bees or queen bees. Unfertilized eggs become drone bees. Eggs in the hive hatch 3 days after they were laid. Worker bees, drone bees and queen bees all have different jobs in the hive.. Worker bees hatch from a fertilized egg and are the female bees. After the female bees hatch, they spend around 6 days in the larval stage. In the larval stage, the bees are fed between 150-800 times per day by the adult worker bees. At this time, fat bodies are being built so that the bee has an adequate amount of storage for lipids, glycogen, amino acids and mitochondria for the bee during the pupal stage. After about 8 or 9 days, the cells with these larva are capped and the larva begin to grow. The pupal stage is the most important ...
The team brings together colleagues from the unit specialized in ontogenesis processes, which are the processes that lead to the establishment of differentiated cells, tissues, organs or functional structures. These processes can occur during the development phases (embryo, larvae) as well as during the juveniles or adult phases: embryogenesis, morphogenesis, gametogenesis, gonadogenesis, neurogenesis and genesis of the shell (biomineralization). All these processes condition closely the adaptation of organisms to their environment and if their determinism is primarily genetic they are also likely influenced by their environment.. Members of the team develop their expertise on economically important species presenting relevant characteristics for the questions addressed: the differently structured germinal niches between oysters (Mollusc, bivalve) and the small-spotted catshark (Vertebrate, Chondrichthyes), gametogenesis blockings observed in triploid oysters with partial sterilisation, the ...
Ontogenetic changes in the relative growth of males and females of the spider crab Maja brachydactyla, a species with terminal moult and determinate growth, were analysed and related to their reproductive (maturity) status. Based on the allometry of cheliped size, two morphometric groups of males separated juvenile and adult phases. Juvenile males also showed two growth phases, immature (smaller ones, without spermatophores) and adolescent (with spermatophores). Size at gonad maturity in males (estimated as CL50) was 96.2 mm carapace length (CL). Histological analysis of males showed that ,60% of morphometric juveniles and 100% of morphometric adults had spermatophores in the gonad. Females begin to develop gonads 2-3 months after the terminal moult. Size at morphometric maturity was estimated comparing two methodologies: the size at 50% maturity (CL50) and the median size of adult cohorts (CLM). In all cases the CLM size at maturity was greater than that resulting from the CL50 method, and, in ...
This paper reports on the application of a chemical fractionation scheme for assessing the amounts, forms and potential mobility (recycling potential) of phosphorus in the sediments of the freshwater Loch Leven, which is currently highly topical in relation to eutrophication and its manifest dense, potentially toxic, blue-green algae. The findings are placed in the context of the biological importance of the loch, the problems it is experiencing and some management options for its restoration. The fractionation scheme adopted enabled quantification of phosphorus in sediment pore water and in sedimentary solid phases classified as loosely-bound, reductant-soluble, oxide-adsorbed, organic, apatite-bound and residual in the sections of a 16-cm core collected in January 1990. Vertical profiles of reductant-soluble and pore water phosphorus and iron show redox-controlled remobilization and cycling within the sediment to be the principal mechanisms leading to the surface sediment enrichment of ...
Redox-regulation of receptors and transcription factors are important for lymphocyte activation, differentiation and apoptosis. Thioredoxin (Trx) is a key redox-regulating protein and oxidative stress sensor operating in synergy with Trx-reductase and protein disulfide isomerase (PDI). The expression of Trx, PDI, and the Trx-regulated transcription-factor Pax5 were analyzed in a panel of human B cell lines and were compared with that of the Bcl-2 family proteins, also redox-controlled. The panel included representative cells from various stages: FLEB14-4 (pro-B), REH and NALM-6 (pre-B), Rael and Daudi (small mature B), U-698 and NC0467.3 (B-blasts), LP-1, U-1996, and U-266 (plasma cells). We found a significant congruence and co-variation of Trx and Bcl-2 levels in the B-lineage, with high expression levels in early stages (pro-B and pre-B) and in the late stage representing terminally-differentiated plasma cells, whereas mid-stage small resting B cells showed a very low expression. PDI ...
