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)I'm not a medical expert, but I can provide you with some information about algal DNA.
Algal DNA refers to the genetic material found in algae, which are simple, photosynthetic organisms that live in various aquatic environments. The DNA of algae is similar to that of other living organisms, as it carries the genetic instructions necessary for the growth, development, and reproduction of these single-celled or multicellular life forms.
Algal DNA can be found in different types of algae, including:
1. Chlorophyta (green algae)
2. Rhodophyta (red algae)
3. Phaeophyceae (brown algae)
4. Cyanobacteria (blue-green algae or cyanoprokaryotes, which are actually bacteria with photosynthetic capabilities)
These different groups of algae have unique characteristics and ecological roles in their environments. Studying the DNA of algae can help researchers understand their evolutionary relationships, genetic diversity, and potential applications in various fields such as biotechnology, bioenergy, and environmental science.
I'm sorry for any confusion, but seaweed is not typically referred to in medical definitions. Seaweed is a common name for various marine macroalgae, which are multicellular aquatic plants found in the ocean. They are often consumed as food and have been used in traditional medicine in some cultures. However, there is no widely accepted medical definition for seaweed. If you're looking for information about a specific compound or substance derived from seaweed that might be relevant to medical definitions, I would be happy to help if you could provide more details.
"Ulva" is a genus of green algae, also known as sea lettuce. It is a common marine plant that can be found in both fresh and saltwater environments worldwide. Ulva species are characterized by their thin, leaf-like blades that can vary in color from bright green to yellowish-green. They play an essential role in the aquatic ecosystem as they provide food and shelter for various marine organisms. Additionally, they can reproduce both sexually and asexually, contributing to their rapid growth and ability to form large colonies or mats. However, when they grow excessively, they can become a nuisance, known as "green tides," which can have negative impacts on the environment and local economies.
Phytoplankton are microscopic photosynthetic organisms that live in watery environments such as oceans, seas, lakes, and rivers. They are a diverse group of organisms, including bacteria, algae, and protozoa. Phytoplankton are a critical component of the marine food chain, serving as primary producers that convert sunlight, carbon dioxide, and nutrients into organic matter through photosynthesis. This organic matter forms the base of the food chain and supports the growth and survival of many larger organisms, including zooplankton, fish, and other marine animals. Phytoplankton also play an important role in global carbon cycling and help to regulate Earth's climate by absorbing carbon dioxide from the atmosphere and releasing oxygen.
Rhodophyta, also known as red algae, is a division of simple, multicellular and complex marine algae. These organisms are characterized by their red pigmentation due to the presence of phycobiliproteins, specifically R-phycoerythrin and phycocyanin. They lack flagella and centrioles at any stage of their life cycle. The cell walls of Rhodophyta contain cellulose and various sulphated polysaccharides. Some species have calcium carbonate deposits in their cell walls, which contribute to the formation of coral reefs. Reproduction in these organisms is typically alternation of generations with a dominant gametophyte generation. They are an important source of food for many marine animals and have commercial value as well, particularly for the production of agar, carrageenan, and other products used in the food, pharmaceutical, and cosmetic industries.
Eukaryota is a domain that consists of organisms whose cells have a true nucleus and complex organelles. This domain includes animals, plants, fungi, and protists. The term "eukaryote" comes from the Greek words "eu," meaning true or good, and "karyon," meaning nut or kernel. In eukaryotic cells, the genetic material is housed within a membrane-bound nucleus, and the DNA is organized into chromosomes. This is in contrast to prokaryotic cells, which do not have a true nucleus and have their genetic material dispersed throughout the cytoplasm.
Eukaryotic cells are generally larger and more complex than prokaryotic cells. They have many different organelles, including mitochondria, chloroplasts, endoplasmic reticulum, and Golgi apparatus, that perform specific functions to support the cell's metabolism and survival. Eukaryotic cells also have a cytoskeleton made up of microtubules, actin filaments, and intermediate filaments, which provide structure and shape to the cell and allow for movement of organelles and other cellular components.
Eukaryotes are diverse and can be found in many different environments, ranging from single-celled organisms that live in water or soil to multicellular organisms that live on land or in aquatic habitats. Some eukaryotes are unicellular, meaning they consist of a single cell, while others are multicellular, meaning they consist of many cells that work together to form tissues and organs.
In summary, Eukaryota is a domain of organisms whose cells have a true nucleus and complex organelles. This domain includes animals, plants, fungi, and protists, and the eukaryotic cells are generally larger and more complex than prokaryotic cells.
18S rRNA (ribosomal RNA) is the smaller subunit of the eukaryotic ribosome, which is the cellular organelle responsible for protein synthesis. The "18S" refers to the sedimentation coefficient of this rRNA molecule, which is a measure of its rate of sedimentation in a centrifuge and is expressed in Svedberg units (S).
The 18S rRNA is a component of the 40S subunit of the ribosome, and it plays a crucial role in the decoding of messenger RNA (mRNA) during protein synthesis. Specifically, the 18S rRNA helps to form the structure of the ribosome and contains several conserved regions that are involved in binding to mRNA and guiding the movement of transfer RNAs (tRNAs) during translation.
The 18S rRNA is also a commonly used molecular marker for evolutionary studies, as its sequence is highly conserved across different species and can be used to infer phylogenetic relationships between organisms. Additionally, the analysis of 18S rRNA gene sequences has been widely used in various fields such as ecology, environmental science, and medicine to study biodiversity, biogeography, and infectious diseases.
Phylogeny is the evolutionary history and relationship among biological entities, such as species or genes, based on their shared characteristics. In other words, it refers to the branching pattern of evolution that shows how various organisms have descended from a common ancestor over time. Phylogenetic analysis involves constructing a tree-like diagram called a phylogenetic tree, which depicts the inferred evolutionary relationships among organisms or genes based on molecular sequence data or other types of characters. This information is crucial for understanding the diversity and distribution of life on Earth, as well as for studying the emergence and spread of diseases.
Molecular evolution is the process of change in the DNA sequence or protein structure over time, driven by mechanisms such as mutation, genetic drift, gene flow, and natural selection. It refers to the evolutionary study of changes in DNA, RNA, and proteins, and how these changes accumulate and lead to new species and diversity of life. Molecular evolution can be used to understand the history and relationships among different organisms, as well as the functional consequences of genetic changes.
DNA Sequence Analysis is the systematic determination of the order of nucleotides in a DNA molecule. It is a critical component of modern molecular biology, genetics, and genetic engineering. The process involves determining the exact order of the four nucleotide bases - adenine (A), guanine (G), cytosine (C), and thymine (T) - in a DNA molecule or fragment. This information is used in various applications such as identifying gene mutations, studying evolutionary relationships, developing molecular markers for breeding, and diagnosing genetic diseases.
The process of DNA Sequence Analysis typically involves several steps, including DNA extraction, PCR amplification (if necessary), purification, sequencing reaction, and electrophoresis. The resulting data is then analyzed using specialized software to determine the exact sequence of nucleotides.
In recent years, high-throughput DNA sequencing technologies have revolutionized the field of genomics, enabling the rapid and cost-effective sequencing of entire genomes. This has led to an explosion of genomic data and new insights into the genetic basis of many diseases and traits.
Chlorophyta is a division of green algae, also known as green plants. This group includes a wide variety of simple, aquatic organisms that contain chlorophylls a and b, which gives them their characteristic green color. They are a diverse group, ranging from unicellular forms to complex multicellular seaweeds. Chlorophyta is a large and varied division with approximately 7,00
Molecular sequence data refers to the specific arrangement of molecules, most commonly nucleotides in DNA or RNA, or amino acids in proteins, that make up a biological macromolecule. This data is generated through laboratory techniques such as sequencing, and provides information about the exact order of the constituent molecules. This data is crucial in various fields of biology, including genetics, evolution, and molecular biology, allowing for comparisons between different organisms, identification of genetic variations, and studies of gene function and regulation.
