The closest relatives of Cercozoa are the Retaria (Foraminifera and Radiozoa; Cavalier-Smith 1999). Radiozoa are all marine unicellular organisms with microtubule-supported axopodia; they comprise the classical polycystine Radiolaria (with silica skeletons), the Acantharea (with strontium sulphate skeletons), which both also possess axopodia, and the curious floating and axopodially swimming Sticholonche which is not mineralized. Radiozoa now excludes the Phaeodarea, which despite their silica skeleton and axopodia, clearly belong in Cercozoa. Phaeodarea appear to be related to the filosan group known as Thecofilosea, which includes filose testate amoebae without silica scales and also the exclusively marine ebriid flagellates, which like the Phaeodarea have a hollow silica endoskeleton, which might therefore have been a common ancestral character for both groups. A hollow silica endoskeleton is unknown in any other eukaryotes. Two groups of Cercozoa (the euglyphid testate amoebae and the ...

Mechanical micromanipulation is a classic method to isolate uncultivated microorganisms or early embryos, and it involves using a capillary pipette to suck up a single cell from a cell suspension with visual inspection of cellular morphology and coloring characteristics under a microscope [13, 14] (Fig. 1b). The drawback of mechanical micromanipulation is that it is low-throughput and time-consuming and can cause cellular injury from mechanical shearing during manipulation [15]. Additionally, it often leads to a failure for an unskilled manipulator or misidentification of the cellular morphology under the microscope.. FACS is the most efficient and economical method to isolate hundreds of thousands of individual cells per minute based on their size, granularity and fluorescence properties [4] (Fig. 1c). The high-throughput, time-saving and automatic properties are the main advantage of FACS. Additionally, it allows researchers to isolate specific individual cells from heterogeneous cell samples ...

Plastids have a tremendous importance in plants as they are the photosynthetic organelles. But their importance extends way beyond this physiological role, as they are also part of the regulatory network that controls the life cycle of the entire plant. Our research is focussed on the integration of the cell organelles (plastids as well as mitochondria) into cellular response regulation of plants with a particular focus on dually targeted proteins.

ABSTRACT Marine phytomyxids (Cercozoa: Phytomyxea) represent a group of obligate biotrophic eukaryotes known for infecting several algae and oomycetes and counted among three taxa generally reported to behave as seagrass-pathogens. Due to their low-key nature, they are observed only sporadically and very limited information about their diversity, life cycles or distribution is available. In order to extend the knowledge of this enigmatic group of marine protists, an extensive research on a phytomyxid found in the invasive seagrass Halophila stipulacea was carried out. In situ observations, light and scanning electron microscopy and molecular methods were used to approach the species ecology, geographical range and phylogenetic placement within the class Phytomyxea. The organism was confirmed to be present in the Red, the Mediterreanean and the Caribbean Sea, suggesting a potential case of a host-parasite comigration on a global scale. Phylogenetically it represents the first and so far the only ...
The Rhizaria are a species-rich supergroup of mostly unicellular[1] eukaryotes.[2] Except from the Chlorarachniophyte and three species in the genus Paulinella in the phylum Cercozoa, they are all non-photosyntethic, but many foraminifers have a symbiotic relationship with unicellular algae. A multicellular form, Guttulinopsis vulgaris, a cellular slime mold, has also been described.[3] This supergroup was proposed by Cavalier-Smith in 2002. Being described mainly from rDNA sequences, they vary considerably in form, having no clear morphological distinctive characters (synapomorphies), but for the most part they are amoeboids with filose, reticulose, or microtubule-supported pseudopods. Many produce shells or skeletons, which may be quite complex in structure, and these make up the vast majority of protozoan fossils. Nearly all have mitochondria with tubular cristae. ...

The Antarctic nematode Panagrolaimus davidi can survive intracellular freezing. Genetic studies indicate the culture strain (now designated as Panagrolaimus sp. DAW1) is a different species to the P. davidi of field origin. This paper reports further attempts both to isolate DAW1 from Antarctic soils and to culture P. davidi itself. Sequencing of the 18S rRNA gene of 151 individuals indicates that DAW1 is rare in the field, but characterising two new isolates shows that, nevertheless, it is present. Panagrolaimus davidi is common in the field, but cannot be cultured using the media tested here. These two species are difficult to distinguish morphologically, apart from the absence of males in DAW1 and its longer recurved tail. Whilst it is possible that DAW1 is an introduced species, the sites at Shackletons hut at Cape Royds are dominated by P. davidi, which is clearly an endemic species.

Penicillin-binding protein 3 (PBP3) of Pseudomonas aeruginosa is the primary target of beta-lactams used to treat pseudomonas infections. Meanwhile, structure change and overproduction of PBP3 play important roles in the drug resistance of P. aeruginosa. Therefore, studies on the gene and structure of PBP3 are urgently needed. P. aeruginosa CMCC 10104 is a type culture strain common used in China. However, there is no report on its genomic and proteomic profiles. In this study, based on ftsl of P. aeruginosa PAO1, the gene encoding PBP3 was cloned from CMCC 10104. A truncated version of the ftsl gene, omitting the bases encoding the hydrophobic leader peptide (amino acids 1-34), was amplified by PCR. The cloned DNA shared 99.76% identity with frsl from PAO1. Only four bases were different (66 C-A, 1020 T-C, 1233 T-C, and 1527 T-C). However, there were no differences between their deduced amino acid sequences. The recombinant PBP3 (rPBP3), containing a 6-histidine tag, was expressed in ...
Small RNAs, including microRNAs (miRNAs) and small interfering RNAs (siRNAs), are important regulators of eukaryotic gene expression by guiding mRNA cleavage, translational inhibition or chromatin modification. We utilize genomics, genetics, molecular and biochemical approaches to identify and functionally characterize infection-regulated small RNAs, including those from plant hosts and from eukaryotic pathogens. My lab provided the first example of a plant endogenous siRNA that regulates plant immune responses. We further discovered that some small RNAs from aggressive fungal pathogens are delivered into host cells to hijack host RNAi machinery to suppress host immunity genes. These studies have added small RNAs to the list of pathogen effectors, which unveiled a novel virulence mechanism in aggressive eukaryotic pathogens. The transport of small RNAs from fungal pathogens to plant hosts also represents a naturally occurring cross-kingdom RNAi event. We recently show that such cross-kingdom ...

Endosulfan is a synthetic cyclodiene non-systemic insecticide and acaricide with both contact and stomach activity. Microorganisms play a key role in removal of xenobiotics like endosulfan from the contaminanted sites because of their dynamic, complex, and complicated enzymatic systems which degrade these chemical. In this study, endosulfan was degraded by indigenous bacteria strains of Pseudomonas aeruginosa and Staphylococcus aureus. The biodegradation process was carried out according to the method established by Buff et al., 1992. The results obtained showed that the bacterial strains efficiently degraded endosulfan by consuming more than 90 % of 40 mg/l of the minimal media within 7 days of incubation. Maximum biodegration by these two selected bacterial stains was observed at an initial pH of 8.0 at an incubation temperature of 30 °C. The findings from present study suggest that these bacterial strains could be potentially promising as a low cost effective technology in the biodegradation ...
1. Immune sera produced in rabbits by treatment with our Culture Strain A of Treponema pallidum agglutinated not only the homologous strain, but also the Noguchi strains, and indicate a close group relationship of other non-pathogenic treponemata. Absorption experiments confirmed this, indicating a close relationship between the pallidum and the calligyrum.. 2. Culture treponemata are not agglutinated to a much greater extent by the sera of syphilitic rabbits than they are by those of normal rabbits.. 3. Culture treponemata are not agglutinated to any considerable extent by the sera of rabbits immunized with virulent treponemata.. 4. The sera of syphilitic patients, especially those in the tertiary stages, agglutinate culture pallidum to a slightly greater extent than do those of normal individuals, but the culture pallidum is agglutinated to an almost equal degree by the sera of many individuals with diseases other than syphilis. We do not think that we could definitely distinguish the ...

A global phylogeny of major eukaryotic lineages is a significant and ongoing challenge to molecular phylogenetics. Currently, there are five hypothesized major lineages or supergroups' of eukaryotes. One of these, the chromalveolates, represents a large fraction of protist and algal diversity. The chromalveolate hypothesis was originally based on similarities between the photosynthetic organelles (plastids) found in many of its members and has been supported by analyses of plastid-related genes. However, since plastids can move between eukaryotic lineages, it is important to provide additional support from data generated from the nuclear-cytosolic host lineage. Genes coding for six different cytosolic proteins from a variety of chromalveolates (yielding 68 new gene sequences) have been characterized so that multiple gene analyses, including all six major lineages of chromalveolates, could be compared and concatenated with data representing all five hypothesized supergroups. Overall support for
TTP Labtech, a global leader in the design and development of automated instrumentation and consumables for life science applications, and the University of California San Diego (UC San Diego), have announced that their collaboration has resulted in a new workflow for single cell sequencing, which reduces the cost of sample preparation by 90%.. The workflow, which has been published in the Journal of Laboratory Automation, was developed through the combination of UC San Diegos expertise in genomics and the use of TTP Labtechs mosquito liquid handlers, which can pipette nanolitre to microlitre volumes with high accuracy and reproducibility, to miniaturise and automate the process.. Although single-cell genomics is advancing rapidly, researchers face challenges linked with reproducibility, sensitivity, scalability and cost, particularly when trying to miniaturize high-throughput applications. To maximize accuracy and precision, library prep protocols recommend volumes that are within the range ...

To date, almost all the pathogen effectors studied or discovered have been proteins," said lead author Hailing Jin, a professor of plant pathology and microbiology. "Ours is the first study to add the RNA molecule to the list of effectors. We expect our work will help in the development of new means to control aggressive pathogens.". Small RNAs guide gene silencing in a wide range of eukaryotic organisms. In the case of Botrytis cinerea, small RNAs silence the expression of host defense genes, resulting in the host plant cells being less able to resist the fungal attack. The process is similar to how protein effectors weaken host immunity in the case of most pathogens.. "What we have discovered is a naturally-occurring cross-kingdom RNAi phenomenon between a fungal pathogen and a plant host that serves as an advanced virulence mechanism," Jin said.. RNA interference or RNAi is a conserved gene regulatory mechanism that is guided by small RNAs for silencing (or suppressing) genes.. Next, Jin and ...
In situ sequencing differs from previous sequencing generations in two respects, both of which are relevant for its use in research and diagnostics. First, the spatial distribution of the sequencing reads over the sample can be seen, adding an important level of information. We demonstrated in our article how this information can be used to visualize tissue heterogeneity based on a number of known molecular markers.. Lee and colleagues showed that subcellular resolution can be achieved with their method, an interesting feature that would allow the study of regulatory elements such as non-coding RNA species in complex populations of cells, for example, in brain tissue. A second difference is the throughput in terms of the number of cells it is possible to simultaneously analyze. Single-cell RNA sequencing methods have been developed to work robustly with just a few picograms of starting material, and there has been an increase in the rate of cell sequencing as well as a decrease in cost [9]. ...
The Rhizaria are a heterogeneous assemblage encompassing lineages such as Foraminifera, radiolarians and euglyphid testate amoebae, chlorarachniophytes, parasitic groups (Phytomyxea, Haplosporidia), as well as a multitude of other lesser-known flagellates (figure 2b) that emerge as having fundamental ecological roles [13,74-76]. Filamentous pseudopodia are a recurrent morphological feature among amoeboid members of Rhizaria, in contrast to the lobose or broad pseudopodia of many Amoebozoa. Complete sexual life cycles are documented for two lineages (Foraminifera and Gromia); karyogamy or meiosis (direct evidence) has been observed in five lineages (Euglyphida, Thecofilosea, Chlorarachniophyta, Plasmodiophorida and Phaeodarea); and indirect evidence (such as cell fusion or formation of putative gametes) has been witnessed in five lineages (Acantharea, Polycystinea, Cercomonas, Helkesimastix and Lateromyxa).. There are at least two lineages in the Rhizaria with confirmed sexual life cycles. ...

Over the last few years, the development of multi-channel sensors motivated interest in methods for the coherent processing of multivariate data. Some specific issues have already been addressed as testified by the wide literature on the so-called blind source separation (BSS) problem. In this context, as clearly emphasized by previous work, it is fundamental that the sources to be retrieved present some quantitatively measurable diversity. Recently, sparsity and morphological diversity have emerged as a novel and effective source of diversity for BSS. We give here some essential insights into the use of sparsity in source separation and we outline the essential role of morphological diversity as being a source of diversity or contrast between the sources. This paper overviews a sparsity-based BSS method coined Generalized Morphological Component Analysis (GMCA) that takes advantages of both morphological diversity and sparsity, using recent sparse overcomplete or redundant signal representations. GMCA

Many aldehydes are important components of natural flavours. They are used in food, cosmetic, and biomedical industries in large amounts. Plant cells or microorganisms carry out their production by biotransformation, which is one of the biotechnological methods that allow them to be defined as natural. Cell cultures of Silybum marianum and Peganum harmala have been studied with a view to investigat their abilities to produce flavonolignans and b-carboline alkaloids respectively. However, we have isolated S. marianum and P. harmala culture strain, which are able to metabolise several aromatic aldehydes. Ten culture strains derived from S. marianum and P. harmala were examined for their ability to biotransform exogenous aromatic aldehyde compounds, including benzaldehyde, 2-methoxybenzaldehyde, 4-methoxybenzaldehyde, cinnamaldehyde and 3-methoxy, 4-hydroxy benzaldehyde. Callus cultures of Silybum marianum and Peganum harmala were established from seedlings, and healthy suspensions were grown using
