Systematic significance of cell inclusions in Haemodoraceae and allied families: silica bodies and tapetal raphides. (1/6)

This paper presents the first record of silica deposits in tissues of Haemodoraceae and adds new records of tapetal raphides in this family. Within the order Commelinales, silica is present in leaves of three families (Hanguanacaeae, Haemodoraceae and Commelinaceae), but entirely absent from the other two (Pontederiaceae and Philydraceae). Presence or absence of characteristic cell inclusions may have systematic potential in commelinid monocotyledons, although the existing topology indicates de novo gains and losses in individual families. Silica sand was observed in leaves of five out of nine genera examined of Haemodoraceae, predominantly in vascular bundle sheath cells and epidermal cells. Within Haemodoraceae, silica is limited to subfamily Conostylidoideae. The occurrence of silica in Phlebocarya supports an earlier transfer of this genus from Haemodoroideae to Conostylidoideae. The presence of raphides (calcium oxalate crystals) in the anther tapetum represents a rare character, only reported in a few monocot families of the order Commelinales, and possibly representing a mechanism for regulation of cytoplasmic free calcium levels. Tapetal raphides were observed here in Anigozanthus and Conostylis (both Haemodoraceae), and Tradescantia (Commelinaceae), thus supplementing two earlier records in Haemodoraceae, Philydraceae and Commelinaceae.  (+info)

Pollinator effectiveness varies with experimental shifts in flowering time. (4/6)

The earlier flowering times exhibited by many plant species are a conspicuous sign of climate change. Altered phenologies have caused concern that species could suffer population declines if they flower at times when effective pollinators are unavailable. For two perennial wildflowers, Tradescantia ohiensis and Asclepias incarnata, we used an experimental approach to explore how changing phenology affects the taxonomic composition of the pollinator assemblage and the effectiveness of individual pollinator taxa. After finding in the previous year that fruit set varied with flowering time, we manipulated flowering onset in greenhouses, placed plants in the field over the span of five weeks, and measured pollinator effectiveness as the number of seeds produced after a single visit to a flower. The average effectiveness of pollinators and the expected rates of pollination success were lower for plants of both species flowering earlier than for plants flowering at historical times, suggesting there could be reproductive costs to earlier flowering. Whereas for A. incarnata, differences in average seed set among weeks were due primarily to changes in the composition of the pollinator assemblage, the differences for T. ohiensis were driven by the combined effects of compositional changes and increases over time in the effectiveness of some pollinator taxa. Both species face the possibility of temporal mismatch between the availability of the most effective pollinators and the onset of flowering, and changes in the effectiveness of individual pollinator taxa through time may add an unexpected element to the reproductive consequences of such mismatches.  (+info)

Pointillist structural color in Pollia fruit. (5/6)

Biological communication by means of structural color has existed for at least 500 million years. Structural color is commonly observed in the animal kingdom, but has been little studied in plants. We present a striking example of multilayer-based strong iridescent coloration in plants, in the fruit of Pollia condensata. The color is caused by Bragg reflection of helicoidally stacked cellulose microfibrils that form multilayers in the cell walls of the epicarp. We demonstrate that animals and plants have convergently evolved multilayer-based photonic structures to generate colors using entirely distinct materials. The bright blue coloration of this fruit is more intense than that of any previously described biological material. Uniquely in nature, the reflected color differs from cell to cell, as the layer thicknesses in the multilayer stack vary, giving the fruit a striking pixelated or pointillist appearance. Because the multilayers form with both helicoidicities, optical characterization reveals that the reflected light from every epidermal cell is polarized circularly either to the left or to the right, a feature that has never previously been observed in a single tissue.  (+info)

The present invention contemplates chromophore-containing polynucleotides having at least two donor chromophores operatively linked to the polynucleotide by linker arms, such that the chromophores are positioned by linkage along the length of the polynucleotide at a donor-donor transfer distance, and at least one fluorescing acceptor chromophore operatively linked to the polynucleotide by a linker arm, such that the fluorescing acceptor chromophore is positioned by linkage at a donor-acceptor transfer distance from at least one of the donor chromophores, to form a photonic structure for collecting photonic energy and transferring the energy to an acceptor chromophore, and methods using the photonic structures.
much broader, although they vary in width and colour. One interesting feature is that the patches of colour that look fiery orange to the naked eye are composed of a mixture of pinkish-red scales interspersed with variable numbers of yellow scales. The whole effect is reminiscent of colours produced in Pointillist paintings, of the kind made famous by George Seurat. By Seurats day (1859-1891) the study of colour had revealed that the close juxtaposition of points of two colours could produce the effect of a third colour when viewed from a distance and Seurat exploited this in his meticulously executed paintings. The computer monitor screen that you are viewing this blogpost on uses a similar principle, of coloured dots, to produce its vast range of colours. Butterflies and moths have been exploiting the same phenomenon for millions of years, to either make themselves conspicuous to mates or generate camouflage patterns. ...
The second show begins as the Pointillist style developed, based on scientific color theory: science says that if we paint in this way, our paintings will glow! The weird thing about that was that, with one exception, every Pointillist piece I saw there appeared absolutely static, no sense of motion at all, even in a painting which showed a skirt blowing in the wind. Only Théo van Rysselberghes Man at the Tiller gave me an actual sense of motion. (If you look it up on line, be aware that the colors do not reproduce correctly!) Still, a woman told me that her husband felt that, when he walked past another Pointillist landscape, the light shifted with him. Maybe thats what they were about. But most of them didnt give me much sense of light direction. Theres a very short distance from some of the Pointillists to Roy Lichtenstein ...
The concept of photonic crystals was born in the late 1980s when two important letters were published that showed the possibility to control light propagation by a periodic structure. A photonic crystals consists of two or more materials with different dielectric functions periodically arranged on the length scale of light. If the conditions are favorable, a gap will open in the dispersion relation, often called photonic band structure, and electromagnetic waves with frequency in the gap range cannot propagate through the photonic crystal.. In this thesis, mainly two types of structures and their properties have been numerically investigated: two-dimensional structures that are either square or triangular. In the calculations, both dielectric and polaritonic materials have been used. Polaritonic materials have an interval of high reflectance in the IR range, due to strong lattice resonances. Within such an interval, the real part of the dielectric function is negative, which causes a metal-like ...
Because of the complex optical signature of plant tissues, it is typically necessary to investigate their anatomical morphology in order to understand the origin of the spectral response. Scanning electron microscopy (SEM) is therefore an indispensable tool, to start analysing the surface of the tissues, since it combines high spatial resolution with relatively simple sample preparation. The standard SEM preparation of biological samples requires chemical fixing to preserve and stabilize the structure of the tissue. A solution of glutaraldehyde is often used as fixative before dehydration by ethanol and critical point drying. To prevent charging by the electron beam, the samples are coated with noble metals, such as gold, using a sputter coater. However, fixing techniques sometimes damage the cuticle of the petal surface. Thus, it can often be advantageous to use cryo-SEM [25] in order to image fully hydrated biological tissues in their chemically unmodified state. Here, fresh samples attached ...

How to Train Your Own Brain - Technology Review: "In addition, focusing on a limited region adds extra noise to the system-much like looking too closely at just one swatch of a Pointillist painting-the mix of odd colors doesnt make sense until you step back and see how the dots fit together.

I learned of the tower when I was five, attracted to the pointillist rings glowing on photos and postcards. I was smitten by the great circular aura shooting into the onyx skyscape from the six carbon arc lamps planted at the towers peak. And when my parents took me to Kelly Park, I became overcome with tumultuous wonder when my little eyes snagged onto a replica of the tower built in History Park. The replica was only 115 feet tall, recently constructed, and I remember asking the tour guide why it was so small. I had somehow remembered the height of the original, plucking it from some stray placard that most tourists ignored. What was the point of reproducing a tower if you couldnt put it in the right place or match the previous height? The tour guide, sifting through his mental arsenal for general historical information to answer my question, told me how the original tower fell. Gale force winds had ravaged the tower on December 3, 1915. It was the deadliest part of a vicious storm. The ...

A phylogenetic analysis of plastid DNA sequences from the trnL-F region corroborates the hypothesis that Haemodoraceae, a small monocotyledonous family centred in southwestern Australia, are monophyletic with relationships to Philydraceae, Pontederiaceae and Comme-linaceae. It also supports the long-standing recognition of two subfamilies. In Conostylidoideae Tribonanthes falls in an isolated position, thus supporting its segregation as a recently recognized monogeneric tribe. Tribal status for Phlebocarya is not supported as this taxon is unexpectedly placed in Conostylideae as sister to Conostylis-Blancoa. Macropidia falls as sister to Anigozanthos. The DNA tree permits continued recognition of Macropidia and Blancoa as distinct genera, contrary to a recent morphological cladistic analysis. Haemodoroideae fall into two clades: (Dilatris(Lachnanthes+Haemodorum)) and (Xiphidium(Schiekia+Wachendofia)). It is unlikely that Haemodoraceae are of Gondwanan origin, and the phylogenetic pattern ...

Three-dimensional-ordered or quasi-ordered structures with appropriately sized spatial variations in RI underpin the structural colours associated with a range of different species across many different animal species, notably birds and butterflies, but also many beetles (Durrer 1977; Vukusic & Sambles 2003; Welch 2005; Prum 2006; Galusha et al. 2008). Natural photonic structures with three-dimensional periodicity appear first to have been identified in some detail among the lepidoptera (Morris 1975) and were originally thought to be rather rare, but are now found with increasing frequency. Although their optical behaviour was originally well understood at a conceptual level, the photonics modelling processes that were available at the time were insufficiently advanced to enable formal theoretical treatments. More recently, with improvements in computing facilities and the development of the field of photonics in technological systems, theoretical modelling methods, by which natural ...
Structural colours and superwettability are of great interest due to their unique characteristics. However, the application of materials with either structural colours or superwettability is limited. Moreover, materials possessing both structural colours and superwettability are crucial for many practical ap

A growing demand of data exchange capacity and sensitive monitoring of quality, as well as of environmentally or health-relevant agents is driving scientific research. In this context, harnessing quantum effects at the individual particle level promises exponentially faster computing, fully secure communications and unparalleled sensing capabilities. Nowadays, photonic structures able to guide light propagation can be designed and engineered in order to efficiently collect the radiation of nearby-placed single emitters, and, thanks to the Purcell effect, it is in principle possible to enhance the coupling into a simple dielectric waveguide mode up to 50%. Single Polyaromathic Hydrocarbons (PAHs) molecules in appropriate host systems coherently interact with light at low temperatures. Such interaction can be controlled at the single photon level when the emitters are efficiently coupled to nanophotonic devices. In such a system, single molecules can play both the role of single photon sources and ...
Photonic structures capable of responding to an analyte with an easily identifiable change in their optical properties have generated wide interest due to their possible application as holographic sensors. Holographic sensors are considered a low-cost, lightweight and disposable technology, and have potential for application in different areas ranging from medical diagnostics to environmental sensing including the monitoring of environmental temperature and relative humidity. In spite of the existing wide range of temperature and humidity sensors, holographic sensors are of special interest as they can provide fast, real-time, reversible or irreversible, visual colorimetric or electronic readouts. The main objective of this project was the development of holographic sensors with response to relative humidity and/or temperature. Holographic humidity sensors were fabricated by holographic recording of volume phase transmission gratings in acrylamide /diacetone acrylamide-based photopolymers containing
I studied the room, and I realized that I now formed a continuum with everything in sight. The room seemed to shimmer in the dying rays of sunlight, and I was aware once more of the atomic substructure that underlay the visible world of the senses. It struck me that the visible world was wholly real, and in no way a deception, but it nevertheless had this underlying structure which glowed and pulsed like a living force. And it all ran together in a single composition. This is hard to describe, and the only analogy I can think of is in painting for example, Seurats huge pointillist canvas, A Sunday Afternoon on the Grande Jatte. The figures on the grass are real enough, and there is a logic to their placement and development; if you look closely, however, you will see that the figures and the grass and the sparkling water are all composed of tiny dots of color, and these dots all blend together to form a single scene and a single reality.

Optical micropillar Bragg cavities of different diameters and coupled by a small bridge have been realized experimentally by means of a focused ion beam system. The resonator modes in these coupled microcavities are either localized in one pillar or delocalized over the whole photonic structure, a fact that could be exploited to control the coupling between two spatially separated quantum dots, i.e. placed in different pillars, via the enhanced electromagnetic field in such a coupled microcavity. A simplified two dimensional simulation has been used to predict the resonant wavelengths and design the optical modes in these coupled Bragg cavities.. ©2007 Optical Society of America.

DOI: 10.1016/j.apsusc.2019.05.273. Traditionally porous silicon based photonic structures have been prepared by electrochemically etching of silicon. In this work, porous multilayers of nanocolumnar SiOx and SiO2 thin films acting as near infrared (NIR) 1D-photonic nanostructures are prepared by magnetron sputtering deposition at oblique angles (MS-OA). Simultaneous control of porosity and stoichiometry of the stacked films is achieved by adjusting the deposition angle and oxygen partial pressure according to a parametric formula. This new methodologoy is proved for the synthesis of SiOx thin films with x close to 0.4, 0.8, 1.2, 1.6 and nanostructures varying from compact (at 0° deposition angle) to highly porous and nanocolumnar (at 70° and 85° deposition angles). The strict control of composition, structure and nanostructure provided by this technique permits a fine tuning of the absorption edge and refraction index at 1500 nm of the porous films and their manufacturing in the form of ...
Mix a pitcher of martinis Tuesday evening to fortify yourself against the torrent of election returns painting a pointillist portrait of the nations mind. Before you become too mellow to care, consider some indexes of our civic tendencies. Voting began, and "persuasion campaigning" receded, weeks ago. Mobilization measures became more important than ads. Saturation spending on ads makes for a steep decline in the utility of the last dollars spent on them. In the 2012 presidential race, $46 million was spent on 56,837 ads in Las Vegas; $30 million was spent on 39,259 in Columbus, Ohio. Ads become audible wallpaper, there but not really noticed. Future campaign money may increasingly be spent on the expensive because labor-intensive business of identifying and prodding to the polls likely supporters. Tammany Hall did this 150 years ago, although its infantry did not carry smartphones with apps sending data about voters to the campaigns. In midterm elections, turnout usually is "frail and pale," ...

ISR-affiliated Associate Professor Miao Yu (ME) is the principal investigator for a three-year, $400K National Science Foundation grant, "Planar photonic crystals for ultra-broadband ultrasound detection and generation." Ultrasound plays an important role in many applications, including health care (e.g., clinical diagnostics, medical therapy, and surgery) and industrial monitoring (e.g., non-destructive detection and material characterization). In all these applications, transducers are critically needed for detection and generation of ultrasound. However, the current ultrasonic transducers are limited in detectability, spatial resolution, and bandwidth, which seriously hinder the performance of existing ultrasonic techniques. This award will support fundamental research on novel artificially designed low-dimensional periodic photonic structures (i.e., planar photonic crystals) for ultrasound detection and generation. This work is expected to open up new avenues for the development of novel ...
The Limnanthaceae are a small family of annual herbs occurring throughout temperate North America. There are eight species and nineteen taxa currently recognized. Members of this family are prominent in vernal pool communities of California. Some taxa have been domesticated for use as an oil seed crop. Some members are listed as threatened or endangered and have been the focus of disputes over development plans (e.g. Limnanthes floccosa subsp. californica, Limnanthes vinculans ) The Limnanthaceae are members of a recently identified clade (Brassicales) of mustard oil producing plants. They have a sharp flavor similar to mustard greens, radish or capers. Two genera are recognized in the family. The monotypic genus Floerkea inhabits shaded, vernally wet habitats in eastern North American deciduous forests, high montane islands in the great basin and humid coniferous forests along the northwest coast. All seven species of Limnanthes, with one British Columbian exception, occur solely in the ...

The dried stem tubers of Pinellia ternata (Thunb.) Breit, P. pedatisecta Schott and Typhonium flagelliforme (Lodd.) Blume from the Araceae family are used as Chinese medicines, namely Banxia, Zhangye Banxia and Shui Banxia, respectively. They have been reported to have a strong irritative effect on mucosa. Previous studies have indicated that the pure raphides of calcium oxalate contained in the stem tubers of three plants have attributed to this strong irritation. However, the processed products of the stem tubers of P. ternata, including Fabanxia, Qingbanxia and Jiangbanxia, have been found to have no irritative effects on mucosa. Currently, the secondary metabolites from the raphides of calcium oxalate contained in the stem tubers of P. ternata with its processed products, P. pedatisecta and T. flagelliforme were analyzed by means of laser microdissection and ultra-high performance liquid chromatography- quadrupole/time of flight-mass spectrometry. The results indicate that the stem tubers of P.
For persons wholly unfamiliar with the musical theatre canon of Stephen Sondheim, the Neo-impressionist artist George Seurat and his famous painting A Sunday on La Grande Jatte, or the work of DC-area director Matthew Gardiner, Sunday in the Park with George at Signature Theatre is worth seeing. For fans and admirers of Sondheim, Seurat, or Gardiner, seeing Signatures production is absolutely essential. In fact, its vital. In the 97-year history of the Pulitzer Prize for drama, only eight musicals have won the coveted award and in 1985, Sondheim and book writer James Lapines fictionalized story of Seurat and his pointillist creation of A Sunday on La Grande Jatte became the sixth musical to achieve such an honor. Inspired by Seurats technique of applying a series of tiny, individual colored dots to form an image, Sondheim not only mimicked the style musically and verbally- through the use of staccato phrases, simple melodies, and clipped conversation-but he even named his female protagonist ...
Fungi are one of the most important and highly diverse organisms. Although some attention has been given to species with interest for conservation biology, such as endangered or invasive alien species, none of these have been examined systematically.. In the present paper, the authors seek to assess the endemicity of Japanese fungi using GBIF-mediated data. Endemic species are unique to a given geographic location, such as an island, country or other defined area. Categorizing a species as endemic should be limited to well-known species to avoid falsely classifying due to lack of data. Proving the endemicity of a species is difficult, if not impossible. Primary biodiversity data, however, makes it easy to confirm the occurrence of a species in an overseas location and thereby ruling out endemicity.. By examining two volumes of Colored Illustrations of Mushrooms of Japan (I and II) (Imazeki and Hong 1987, 1989), a masterpiece of mycobiota information, researchers reviewed the comments of 3,928 ...
Do you want the good news or the bad news? We now have 8821 names on the International Bromeliad Cultivar Register of which 4366 are Neoregelia. If you wanted to buy one of these plants how lucky would you be? Many of the older ones would be very difficult to find. With many of the newer ones you could try contacting the hybridist but even then you could have problems. Let me explain.. In the good-old-days, Nurseries printed Catalogues and advertised their wares in various Newsletters and Journals. However, as Herb Plever from New York already pointed out these Catalogues are becoming few and far between and yet plants, especially hybrids, are still sold and purchased around the world.. Ever since I became Registrar in 2000 I have tried to point out the advantages of registering hybrids if only to give some way of identification compared to the names that just occur in Catalogues, which for want of a term I have always called Nurserymen s Names or NN for short. If mentioned in a Bromeliad ...

The latest achievements in the fabrication of thin layers of black phosphorus (BP), toward the technological breakthrough of a phosphorene atomically thin layer, are paving the way for their use in electronics, optics, and optoelectronics. In this work, we have simulated the optical properties of one-dimensional photonic structures, i.e., photonic crystals and microcavities, in which few-layer BP is one of the components. The insertion of the 5-nm black phosphorous layers leads to a photonic band gap in the photonic crystals and a cavity mode in the microcavity that is interesting for light manipulation and emission enhancement.. © 2016 Optical Society of America.

Self-assembly of colloidal particles produces structural materials for a broad range of applications such as metamaterials (1), solar cells (2), photonic sensors (3), and drug delivery (4). In most of these applications, the assembly of colloids results in structural colors that are more resistant to chemical washing or photobleaching than pigment-based colors (5, 6). The current state-of-the-art structural colors from colloidal assemblies are mostly constrained to film geometries using evaporation-induced assembly (7), electrophoretic deposition (8), and spray coating (9). These films are difficult to apply as "pigment-like" colorants that can be directly added to other materials such as paints or textiles. Furthermore, the interference-based structural colors on flat substrates are mostly iridescent, limiting their use in wide-angle display or accurate sensing applications. Recently, a simple approach involving self-assembly of colloidal nanoparticles in emulsion droplets was used to fabricate ...
Family Tingidae (lace bugs). Adults and nymphs of Megalocysta gibbifera (Picado) (Hemiptera: Tingidae) were noted to feed on Aechmea bromeliad leaves at Orosí in Costa Rica, and the nymphs were sometimes parasitized by larvae of small wasps possibly of Braconidae (Picado 1913). Their discoverer was perplexed that they should often be found stuck firmly in the gelatinous gum exuded by their host plants. This writer wonders whether the conditions for adhesion of the tingids were created by the method of their capture (dismembering bromeliads using considerable force and perhaps accidentally pressing the insects into the gum); his observations are that such gum is secreted only when bromeliads and members of some related families undergo gross physical damage (for example by breaking a bromeliad flower spike, or tearing the leaves from a stem); thus, under normal circumstances no gum would be exuded, so the tingids would not encounter it. ...
This study presents a list of species of the two most important families with epiphytic elements, Bromeliaceae and Orchidaceae, from the Reserva de la Biosfera Barranca de Metztitlán (RBBM), the largest Reserve in Hidalgo, Mexico. Thirty-four species are included, 26 corresponding to species in three genera of bromeliads, and eight species in six genera of orchids. The new records represent 26.5% of the total listed in the area; nine of them are new records for the Reserve (RBBM) and one is new for Hidalgo State. This study reveals that endemism for both families is very important in the Reserve (55.88%), since it includes 13 Mexican bromeliads, of which two are endemic to Hidalgo and one to the Reserve, and three orchids, two endemic to Mexico and one to the Reserve. We found species with different types of relative abundance: rare (16) and occasional (7). Additionally, we include information about the category (IUCN, CITES, NOM-059-SEMARNAT) as well as uses reported in the literature for the species
A perfect present sending a plant is the gift which keeps on giving. Vibrant oranges and yellows feature in this potted bromeliad, perfect to show someone how much you care.
Bromeliaceae (the bromeliads) is a family of monocot flowering plants of around 3,170 species native mainly to the tropical Americas, with a few species found in the American subtropics and one in tropical west Africa, Pitcairnia feliciana. It is the one of the basal families within the Poales and is unique because it is the only family within the order that has septal nectaries and inferior ovaries. These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both epiphytes, such as Spanish moss (Tillandsia usneoides), and terrestrial species, such as the pineapple (Ananas comosus). Many bromeliads are able to store water in a structure formed by their tightly-overlapping leaf bases. However, the family is diverse enough to include the tank bromeliads, grey-leaved epiphytic Tillandsia species that gather water only from leaf structures called trichomes, and a large number of desert-dwelling succulents. The largest bromeliad is Puya raimondii, which ...

The structural colours of butterflies and moths (Lepidoptera) have been attributed to a diversity of physical mechanisms, including multilayer interference, diffraction, Bragg scattering, Tyndall scattering and Rayleigh scattering. We used fibre optic spectrophotometry, transmission electron microscopy (TEM) and 2D Fourier analysis to investigate the physical mechanisms of structural colour production in twelve lepidopteran species from four families, representing all of the previously proposed anatomical and optical classes of butterfly nanostructure. The 2D Fourier analyses of TEMs of colour producing butterfly scales document that all species are appropriately nanostructured to produce visible colours by coherent scattering, i.e. differential interference and reinforcement of scattered, visible wavelengths. Previously hypothesized to produce a blue colour by incoherent, Tyndall scattering, the scales of Papilio zalmoxis are not appropriately nanostructured for incoherent scattering. Rather, ...
Aechmea fasciata is an epiphytic Bromeliad from Brazil. Aechmeas are among the most beautiful of all Bromeliads for indoor decoration. Large, colorful blooms rise high above the vase-shaped rosette of leaves. Blooming time: Most Bromeliads will flower naturally when they reach maturity; they can also be made to flower by supplying the substances which begin bud formation: for example, enclose the entire plant ( with its cup empty of water to prevent excessive humidity buildup) in a plastic bag together with a ripe apple. The apple gives off ethylene gas which stimulates flowering in Bromeliads. Leave plant and apple in the plastic bag for 7-10 days; f lower will appear in 1-2 months. Culture: Add peatmoss to an equal volume of general house plant mix for a humusy and well drained combination. Soil may dry out between waterings. Keep water in central cup formed by leafy rosette. Fertilize every 1-2 months, applied to the soil. Or fill the cup with half-strength dilution of fertilizer every month. ...
The beneficial influence of an aerobic propagation medium for in vitro cultures during the rooting phase was found for 28 Australian species and genotypes from the families Liliaceae, Haemodoraceae, Myrtaceae, Thymelaeaceae, Proteaceae, Goodeniaceae and Rutaceae. Microcuttings from established shoot cultures were pulsed for 7 days in the dark on a high-auxin (40 μM indole-3-butyric acid, IBA), agar-solidified medium. The microcuttings were then transferred either to an agar-solidified medium without plant-growth regulators (M1) or a sterile propagation mix. The protocol utilising propagation mix used is referred to as IVS (in vitro soil-less medium). The pulsed cuttings in agar or IVS were placed in the culture room under standard light and temperature regimes and allowed to root. When compared over two harvest times, the use of IVS as a rooting medium gave consistent improvements over the use of M1 medium for percentage rooting, average total root length and root number per microcutting.

What is it about we gardeners that when we see a plant we really love, the next thing you know weve got two hundred of them???? (or around three hundred fifty or so as is the case with my bromeliads) Or is it just me? I really dont think so as Ive seen a lot of beautiful and very large collections of all sorts of plants on peoples blogs. Anyway, my most recent obsession is bromeliads. I absolutely adore them. They come in all different sizes, colors and patterns and are easy peasy to take care of. Unfortunately or fortunately depending on how much room a gardener has, they grow, bloom and send out pups like agaves. So, I now have multiples of just about everything, they are all growing to adulthood and its time to bring things indoors and also time to thin out my collection.

Chronic liver disease with cirrhosis is the 12th leading cause of death in the United States, and alcoholic liver disease accounts for approximately half of all cirrhosis deaths. Chronic alcohol consumption is associated with intestinal bacterial dysbiosis, yet we understand little about the contribution of intestinal fungi, or mycobiota, to alcoholic liver disease. Here we have demonstrated that chronic alcohol administration increases mycobiota populations and translocation of fungal β-glucan into systemic circulation in mice. Treating mice with antifungal agents reduced intestinal fungal overgrowth, decreased β-glucan translocation, and ameliorated ethanol-induced liver disease. Using bone marrow chimeric mice, we found that β-glucan induces liver inflammation via the C-type lectin-like receptor CLEC7A on Kupffer cells and possibly other bone marrow-derived cells. Subsequent increases in IL-1β expression and secretion contributed to hepatocyte damage and promoted development of ...
