Rational analyses of organelle trajectories in tobacco pollen tubes reveal characteristics of the actomyosin cytoskeleton. (1/2581)

To gain insight into the characteristics of organelle movement and the underlying actomyosin motility system in tobacco pollen tubes, we collected data points representing sequential organelle positions in control and cytochalasin-treated cells, and in a sample of extruded cytoplasm. These data were utilized to reconstruct approximately 900 tracks, representing individual organelle movements, and to produce a quantitative analysis of the movement properties, supported by statistical tests. Each reconstructed track appeared to be unique and to show irregularities in velocity and direction of movement. The regularity quotient was near 2 at the tip and above 3 elsewhere in the cell, indicating that movement is more vectorial in the tube area. Similarly, the progressiveness ratio showed that there were relatively more straight trajectories in the tube region than at the tip. Consistent with these data, arithmetical dissection revealed a high degree of randomlike movement in the apex, lanes with tip-directed movement along the flanks, and grain-directed movement in the center of the tube. Intercalated lanes with bidirectional movement had lower organelle velocity, suggesting that steric hindrance plays a role. The results from the movement analysis indicate that the axial arrangement of the actin filaments and performance of the actomyosin system increases from tip to base, and that the opposite polarity of the actin filaments in the peripheral (+-ends of acting filaments toward the tip) versus the central cytoplasm (+-ends of actin filaments toward to the grain) is installed within a few minutes in these tip-growing cells.

Male gametic cell-specific gene expression in flowering plants. (2/2581)

The role of the male gamete-the sperm cell-in the process of fertilization is to recognize, adhere to, and fuse with the female gamete. These highly specialized functions are expected to be controlled by activation of a unique set of genes. However, male gametic cells traditionally have been regarded as transcriptionally quiescent because of highly condensed chromatin and a very reduced amount of cytoplasm. Here, we provide evidence for male gamete-specific gene expression in flowering plants. We identified and characterized a gene, LGC1, which was shown to be expressed exclusively in the male gametic cells. The gene product of LGC1 was localized at the surface of male gametic cells, suggesting a possible role in sperm-egg interactions. These findings represent an important step toward defining the molecular mechanisms of male gamete development and the cellular processes involved in fertilization of flowering plants. (+info)

Exhaled and nasal NO levels in allergic rhinitis: relation to sensitization, pollen season and bronchial hyperresponsiveness. (3/2581)

Exhaled nitric oxide is a potential marker of lower airway inflammation. Allergic rhinitis is associated with asthma and bronchial hyperresponsiveness. To determine whether or not nasal and exhaled NO concentrations are increased in allergic rhinitis and to assess the relation between hyperresponsiveness and exhaled NO, 46 rhinitic and 12 control subjects, all nonasthmatic nonsmokers without upper respiratory tract infection, were randomly selected from a large-scale epidemiological survey in Central Norway. All were investigated with flow-volume spirometry, methacholine provocation test, allergy testing and measurement of nasal and exhaled NO concentration in the nonpollen season. Eighteen rhinitic subjects completed an identical follow-up investigation during the following pollen season. Exhaled NO was significantly elevated in allergic rhinitis in the nonpollen season, especially in perennially sensitized subjects, as compared with controls (p=0.01), and increased further in the pollen season (p=0.04), mainly due to a two-fold increase in those with seasonal sensitization. Nasal NO was not significantly different from controls in the nonpollen season and did not increase significantly in the pollen season. Exhaled NO was increased in hyperresponsive subjects, and decreased significantly after methacholine-induced bronchoconstriction, suggesting that NO production occurs in the peripheral airways. In allergic rhinitis, an increase in exhaled nitric oxide on allergen exposure, particularly in hyperresponsive subjects, may be suggestive of airway inflammation and an increased risk for developing asthma.

LeProT1, a transporter for proline, glycine betaine, and gamma-amino butyric acid in tomato pollen. (4/2581)

During maturation, pollen undergoes a period of dehydration accompanied by the accumulation of compatible solutes. Solute import across the pollen plasma membrane, which occurs via proteinaceous transporters, is required to support pollen development and also for subsequent germination and pollen tube growth. Analysis of the free amino acid composition of various tissues in tomato revealed that the proline content in flowers was 60 times higher than in any other organ analyzed. Within the floral organs, proline was confined predominantly to pollen, where it represented >70% of total free amino acids. Uptake experiments demonstrated that mature as well as germinated pollen rapidly take up proline. To identify proline transporters in tomato pollen, we isolated genes homologous to Arabidopsis proline transporters. LeProT1 was specifically expressed both in mature and germinating pollen, as demonstrated by RNA in situ hybridization. Expression in a yeast mutant demonstrated that LeProT1 transports proline and gamma-amino butyric acid with low affinity and glycine betaine with high affinity. Direct uptake and competition studies demonstrate that LeProT1 constitutes a general transporter for compatible solutes. (+info)

Process and current status of the epidemiologic studies on cedar pollinosis in Japan. (5/2581)

This paper reviews the present situation and future aspects of epidemiologic studies on Japanese cedar pollinosis. Increase of allergic rhinitis patients is observed in both the Patient Survey and the Reports on the Surveys of Social Medical Care Insurance Services, however, these surveys are conducted when cedar pollens do not pollute the air. Many have reported on the prevalence of pollinosis in limited areas but only a few nationwide epidemiologic surveys have been conducted. Most of the studies were conducted at special medical facilities such as university hospitals. There is a high possibility that patients who visit the specific facilities do not exactly represent the actual number of patients and epidemiologic pictures of pollinosis in Japan. The rapid advances in laboratory test methods may change the diagnostic criteria and increase the number of reported patients. Therefore, the prevalence of Japanese cedar pollinosis in Japan has not been determined yet. Determination of the prevalence of cedar pollinosis and description of the epidemiologic pictures constitute the essential steps toward the control of this clinical entity. Thus it is necessary to conduct an epidemiologic survey on Japanese representative samples with a standardized survey form with clear and concise diagnostic criteria. (+info)

Pollen ultrastructure in anther cultures of Datura innoxia. I. Division of the presumptive vegetative cell. (6/2581)

Ultrastructural features of embryogenic pollen in Datura innoxia are described, just prior to, during, and after completion of the first division of the presumptive vegetative cell. In anther cultures initiated towards the end of the microspore phase and incubated at 28 degrees C in darkness, the spores divide within 24 h and show features consistent with those of dividing spores in vivo. Cytokinesis is also normal in most of the spores and the gametophytic cell-plate curves round the presumptive generative nucleus in the usual highly ordered way. Further differentiation of the 2 gametophytic cells does not take place and the pollen either switches to embryogenesis or degenerates. After 48-72 h, the remaining viable pollen shows the vegetative cell in division. The cell, which has a large vacuole and thin layer of parietal cytoplasm carried over from the microspore, divides consistently in a plane parallel to the microspore division. The dividing wall follows a less-ordered course than the gametophytic wall and usually traverses the vacuole, small portions of which are incorporated into the daughter cell adjacent to the generative cell. The only structural changes in the vegetative cell associated with the change in programme appear to be an increase in electron density of both plastids and mitochondria and deposition of an electron-dense material (possibly lipid) on the tonoplast. The generative cell is attached to the intine when the vegetative cell divides. Ribosomal density increases in the generative cell and exceeds that in the vegetative cell. A thin electron-dense layer also appears in the generative-cell wall. It is concluded that embryogenesis commences as soon as the 2 gametophytic cells are laid down. Gene activity associated with postmitotic synthesis of RNA and protein in the vegetative cell is switched off. The data are discussed in relation to the first division of the embryogenic vegetative cells in Nicotiana tabacum. (+info)

Pollen ultrastructure in anther cultures of Datura innoxia. II. The generative-cell wall. (7/2581)

In young pollen grains of Datura innoxia, a wall of the usual hemispherical type separates the 2 gametophytic cells initially and, in the electron microscope, appears as an electron-translucent matrix which is contiguous with the intine. Before detachment of the generative cell from the intine, the matrix decreases in thickness and in places is dispersed altogether leaving the plasmalemmae on either side of it in close apposition. A particularly prominent zone, triangular in profile, is left where the wall joins with the intine. After detachment of the cell, remnants of the matrix can be seen distributed irregularly around the cell and it is supposed that these are partly derived from material in the triangular zone as the cell is drawn away from the intine. The wall residues persist throughout the maturation phase of the pollen and are considered to be either callose resulting from incomplete digestion of the initial wall, or some other polysaccharide material which is unevenly laid down along the wall and concentrated at the junction with the intine. In pollen induced into embryogenesis by anther culture, wall material is also distributed irregularly around the detached cell in a series of discrete zones, but these are more extensive than in vivo, closer together and in many instances highly dilated. The wall profiles thus have a beaded appearance, the 'beads' being connected together by short links of the 2 apposed plasmalemmae. The contents of the swollen zones have a similar electron density to that of the matrix in vivo but also show traces of a fibrillar component. It is postulated that this unusual swelling is a prelude to dispersal of the wall by disruption of the plasmalemmal links and to the establishment of cytoplasmic continuity between the 2 cells. The significance of such binucleate pollen grains in the formation of non-haploid embryos is discussed. (+info)

Pollen ultrastructure in anther cultures of Datura innoxia. III. Incomplete microspore division. (8/2581)

During the microspore division in Datura innoxia, the mitotic spindle is oriented in planes both perpendicular (PE) and oblique (OB) to the spore wall against which the nucleus is situated. However, irrespective of polarity, the usual type of hemispherical wall is laid down at cytokinesis and isolates the generative cell from the rest of the pollen grain (type A). In PE spores the vegetative nucleus initially occupies a central position in the pollen grain, whereas in OB spores the vegetative nucleus lies at the periphery of the grain close to the generative cell. In anther cultures initiated just before the microspore division is due to take place, no marked change can be observed in either orientation or symmetry of the mitotic spindle when the spores divide. In some, however, cytokinesis is disrupted and deposition of the hemispherical wall arrested. In the absence of a complete wall, differentiation of the generative cell cannot take place and binucleate pollen grains are formed having 2 vegetative-type nuclei (type B). The 2 nuclei in the B pollens are always situated against the pollen-grain wall, suggesting that the disruption phenomenon is related to the OB spores. The incomplete wall always makes contact with the intine on the intine-side of the spindle. Wall material may be represented merely as short stubs projecting out from the intine into the cytoplasm, in which event the 2 nuclei lie close to each other and are separated by only a narrow zone of cytoplasm. In other grains the wall is partially developed between the nuclei and terminates at varying distances from the tonoplast; in these, the nuclei are separated by a wider zone of cytoplasm. The significance of these binucleate grains in pollen embryogenesis is discussed. (+info)

Rhinitis, allergic, seasonal, is a type of inflammation of the nasal passages that occurs in response to exposure to allergens, such as pollen, mold spores, or dust mites, that are typically present in the environment during certain times of the year. It is also known as seasonal allergic rhinitis or hay fever. Symptoms of seasonal allergic rhinitis can include sneezing, runny nose, itchy or watery eyes, congestion, and postnasal drip. These symptoms are usually worse in the morning or after exposure to allergens and can be relieved with over-the-counter antihistamines or nasal decongestants. Seasonal allergic rhinitis is a common condition that affects millions of people worldwide. It is typically treated with avoidance of allergens, the use of medications to relieve symptoms, and immunotherapy (allergy shots) to reduce sensitivity to allergens over time.

Plant proteins are proteins that are derived from plants. They are an important source of dietary protein for many people and are a key component of a healthy diet. Plant proteins are found in a wide variety of plant-based foods, including legumes, nuts, seeds, grains, and vegetables. They are an important source of essential amino acids, which are the building blocks of proteins and are necessary for the growth and repair of tissues in the body. Plant proteins are also a good source of fiber, vitamins, and minerals, and are generally lower in saturated fat and cholesterol than animal-based proteins. In the medical field, plant proteins are often recommended as part of a healthy diet for people with certain medical conditions, such as heart disease, diabetes, and high blood pressure.

Immunoglobulin E (IgE) is a type of antibody that plays a key role in the immune system's response to allergens and parasites. It is produced by B cells in response to specific antigens, such as those found in pollen, dust mites, or certain foods. When an allergen enters the body, it triggers the production of IgE antibodies by B cells. These antibodies then bind to mast cells and basophils, which are immune cells that are involved in the inflammatory response. When the same allergen enters the body again, the IgE antibodies on the mast cells and basophils bind to the allergen and cause the release of histamine and other inflammatory chemicals. This leads to symptoms such as itching, swelling, and difficulty breathing. IgE is also involved in the immune response to parasites, such as worms. In this case, the IgE antibodies help to trap and kill the parasites by binding to them and marking them for destruction by other immune cells. Overall, IgE is an important part of the immune system's defense against allergens and parasites, but it can also contribute to allergic reactions and other inflammatory conditions when it binds to inappropriate antigens.

Arabidopsis Proteins refer to proteins that are encoded by genes in the genome of the plant species Arabidopsis thaliana. Arabidopsis is a small flowering plant that is widely used as a model organism in plant biology research due to its small size, short life cycle, and ease of genetic manipulation. Arabidopsis proteins have been extensively studied in the medical field due to their potential applications in drug discovery, disease diagnosis, and treatment. For example, some Arabidopsis proteins have been found to have anti-inflammatory, anti-cancer, and anti-viral properties, making them potential candidates for the development of new drugs. In addition, Arabidopsis proteins have been used as tools for studying human diseases. For instance, researchers have used Arabidopsis to study the molecular mechanisms underlying human diseases such as Alzheimer's, Parkinson's, and Huntington's disease. Overall, Arabidopsis proteins have become an important resource for medical research due to their potential applications in drug discovery and disease research.

Hypersensitivity is a medical term used to describe an exaggerated immune response to a substance that is normally harmless or even beneficial to the body. This response can occur in response to a variety of stimuli, including allergens, toxins, and medications. There are four main types of hypersensitivity reactions, each with its own specific characteristics and mechanisms: 1. Type I hypersensitivity (also known as immediate hypersensitivity) is an allergic reaction that occurs within minutes or hours of exposure to an allergen. It is mediated by IgE antibodies and involves the release of histamine and other inflammatory mediators from mast cells and basophils. 2. Type II hypersensitivity (also known as cytotoxic hypersensitivity) is an immune response that involves the destruction of cells by antibodies. It is typically seen in autoimmune diseases, where the immune system mistakenly attacks the body's own cells. 3. Type III hypersensitivity (also known as immune complex-mediated hypersensitivity) is an immune response that involves the formation of immune complexes, which can deposit in tissues and trigger inflammation. It is seen in conditions such as systemic lupus erythematosus and rheumatoid arthritis. 4. Type IV hypersensitivity (also known as delayed-type hypersensitivity) is an immune response that occurs over a period of days or weeks after exposure to an allergen or antigen. It involves the activation of T cells and the release of cytokines, which can cause inflammation and tissue damage. Overall, hypersensitivity reactions can range from mild to severe and can cause a wide range of symptoms, including itching, swelling, redness, and pain. Treatment typically involves avoiding the allergen or antigen that triggers the reaction, as well as medications to manage symptoms and reduce inflammation.

Despite the importance of pollination, for many years research has been limited as there is no efficient way to study pollen distribution or track individual pollen grains. (soci.org)
The quantum dots were equipped with lipophilic (fat-loving) ligands to allow them to stick to the fatty outer layer of pollen grains. (soci.org)
Bee was caught after it visited a flower of which the pollen grains were labelled with quantum dots. (soci.org)
After successfully labelling the pollen, the next step was to design a cheap and effective method to view the fluorescent pollen grains under a field dissection microscope. (soci.org)
The method has proven to be successful in tracking individual pollen grains so far, despite the meticulous pollen counting work that is required. (soci.org)
data concerning pollen grains should not be used in Shroud research. (shroudstory.com)
A paper from the Valencia conference, The question of pollen grains on the Shroud of Turin and the Sudarium of Oviedo , by Emanuela Marinelli, came up in the discussion. (shroudstory.com)
In subsequent analyses of dust samples it was possible to find and classify a large number of pollen grains which, properly treated, have allowed the precise determination of the family, genus and species of the plant itself. (shroudstory.com)
He examined 165 pollen grains, of which 45 (27.3%) were Gundelia tournefortii. (shroudstory.com)
Prof. Litt concluded that none of the pollen grains he saw could be named at a species level. (shroudstory.com)
Hence, all the conclusions drawn from previous palynological investigations of Dr. Frei's material should be suspended until a new collection of pollen grains can be carried out and the grains thus obtained can be studied with modern equipment and by an expert of pollen of this area. (shroudstory.com)
Since writing [Prof. Litt's] conclusions in 2001 no pollen grains have been collected and investigated as he suggested, so the data concerning pollen grains should not be used in Shroud research. (shroudstory.com)
In order for pollination to occur, pollen grains must be transferred from the anther to the female stigma of another plant. (zyrtec.com)
They have found fossilised grains of pollen that provide us with answers to what happened to plant life at the time of the extinction of the dinosaurs. (lu.se)
Looking at variations in pollen grains is therefore a good way to study how plant life changed after the asteroid impact. (lu.se)
Some pollen grains look the same as their modern equivalents, and sometimes the researchers are lucky enough to find a fossilised flower with its pollen - this makes it possible to identify more specifically what plant the pollen is from. (lu.se)
The surface of pollen grains is reinforced by pollen wall components produced noncell autonomously by tapetum cells that surround developing pollen within the male floral organ, the anther. (bvsalud.org)
Coordination of tapetum activity with pollen grain development depends on the action of subtilases, including AtSBT5.4, which are produced stage specifically by developing pollen grains . (bvsalud.org)

Climate change will potentially lead to both higher pollen concentrations and longer pollen seasons, causing more people to suffer more health effects from pollen and other allergens. (cdc.gov)

Allergic conjunctivitis is the inflammation of the lining of the eye (conjunctiva) due to exposure to allergens like those in pollen. (cdc.gov)
Higher pollen concentrations and longer pollen seasons can also make you more sensitive to allergens. (cdc.gov)

Each microscopic grain of pollen contains proteins that can cause allergic reactions when breathed in. (kidshealth.org)
The process whose specific outcome is the progression of the pollen grain over time, from its formation to the mature structure. (mcw.edu)
The nucleus of each microspore then divides by mitosis to form a two-celled organism, the pollen grain, that contains a tube cell as well as a smaller generative cell. (mcw.edu)
The pollen grain is surrounded by an elaborate cell wall. (mcw.edu)
In most flowering plants, however this division takes place later, in the tube that develops when a pollen grain germinates. (mcw.edu)
Pollen grain coats from the end of the dinosaur era. (lu.se)
Only the outer shell of the pollen grain is preserved in the rock, but that is sufficient to be able to identify what type of plant the pollen came from - whether a flowering plant or a coniferous tree. (lu.se)

While pollen allergies might appear to be the unavoidable cost of living with flowering plants, the suffering engendered by pollen allergies is largely our own creation. (minnesotalawreview.org)
Reducing much of the human suffering caused by pollen allergies simply requires removing certain allergenic plants from cities and replacing them with less allergenic species near where we live and work. (minnesotalawreview.org)
Several cities already regulate allergenic plants, but government can do more to reduce pollen allergies. (minnesotalawreview.org)

The IC50 results for saffron pollen extract was found to be 0.177 ± 0.08, 0.191 ± 0.09, 0.182 ± 0.08 g per 100 g, for 140, 160 and 180 , respectively. (magiran.com)

Though pollen counts are typically higher during the warmer seasons, some plants pollinate year-round. (cdc.gov)
Changes in patterns of outdoor aeroallergens caused by increasing temperatures and amounts of carbon dioxide in the atmosphere are major factors linked to increased duration of pollen seasons, increased pollen production, and possibly increased allergenicity of pollen. (cdc.gov)
Longer warm seasons mean longer pollen seasons. (cdc.gov)
From 1995 to 2011, pollen seasons lasted two weeks longer in some northern cities. (cdc.gov)

With these five species, the most important species are covered throughout the entire pollen season, as they bloom one after another over the course of the year. (admin.ch)
MeteoSwiss is now expanding this system and investing in development work concerning the calculation of the pollen count, for example to improve the quality of the pollen counts for the existing species or to introduce additional pollen species that are important for allergy sufferers. (admin.ch)
It is not true that pollen is classifiable at species level even today, and was even less so 40 years ago. (shroudstory.com)

Warmer temperatures affect pollen production. (richmondmagazine.com)

For narrow valleys such as the Lauterbrunnental (Fr: Val d'Hérens, It: Val Verzasca), however, the resolution of 1.1 km is still too coarse for a local pollen forecast. (admin.ch)

Rather, brush off excess pollen and hang garment outdoors in direct sunlight for a few hours and the stain will disappear! (tellmehowto.net)

Since pollen is small, dry, and lightweight, it can easily become airborne and be spread over long distances by wind. (zyrtec.com)

The scientists are already using the methodology for finding new information about the distribution of pollen. (soci.org)

Bee pollen is flower pollen that's collected by worker bees, mixed with nectar and bee saliva, and then packed into honeycomb cells in the hive. (medlineplus.gov)

Pollen forecast with COSMO-ART - how should the maps be interpreted? (admin.ch)
The numerical weather forecast model used by MeteoSwiss, COSMO, can model the pollen count with the ART pollen module. (admin.ch)
This makes it possible to correct the COSMO pollen forecast at regular intervals with the real-time data and thus improve it. (admin.ch)

The amount and type of pollen in the air depends on the season and geographic region. (cdc.gov)
