Biosynthesis of L-ascorbic acid and conversion of carbons 1 and 2 of L-ascorbic acid to oxalic acid occurs within individual calcium oxalate crystal idioblasts. (1/90)

L-Ascorbic acid (AsA) and its metabolic precursors give rise to oxalic acid (OxA) found in calcium oxalate crystals in specialized crystal idioblast cells in plants; however, it is not known if AsA and OxA are synthesized within the crystal idioblast cell or transported in from surrounding mesophyll cells. Isolated developing crystal idioblasts from Pistia stratiotes were used to study the pathway of OxA biosynthesis and to determine if idioblasts contain the entire path and are essentially independent in OxA synthesis. Idioblasts were supplied with various (14)C-labeled compounds and examined by micro-autoradiography for incorporation of (14)C into calcium oxalate crystals. [(14)C]OxA gave heavy labeling of crystals, indicating the isolated idioblasts are functional in crystal formation. Incubation with [1-(14)C]AsA also gave heavy labeling of crystals, whereas [6-(14)C]AsA gave no labeling. Labeled precursors of AsA (L-[1-(14)C]galactose; D-[1-(14)C]mannose) also resulted in crystal labeling, as did the ascorbic acid analog, D-[1-(14)C]erythorbic acid. Intensity of labeling of isolated idioblasts followed the pattern OxA > AsA (erythorbic acid) > L-galactose > D-mannose. Our results demonstrate that P. stratiotes crystal idioblasts synthesize the OxA used for crystal formation, the OxA is derived from the number 1 and 2 carbons of AsA, and the proposed pathway of ascorbic acid synthesis via D-mannose and L-galactose is operational in individual P. stratiotes crystal idioblasts. These results are discussed with respect to fine control of calcium oxalate precipitation and the concept of crystal idioblasts as independent physiological compartments.  (+info)

Interaction of sulfate assimilation with carbon and nitrogen metabolism in Lemna minor. (2/90)

Cysteine synthesis from sulfide and O-acetyl-L-serine (OAS) is a reaction interconnecting sulfate, nitrogen, and carbon assimilation. Using Lemna minor, we analyzed the effects of omission of CO(2) from the atmosphere and simultaneous application of alternative carbon sources on adenosine 5'-phosphosulfate reductase (APR) and nitrate reductase (NR), the key enzymes of sulfate and nitrate assimilation, respectively. Incubation in air without CO(2) led to severe decrease in APR and NR activities and mRNA levels, but ribulose-1,5-bisphosphate carboxylase/oxygenase was not considerably affected. Simultaneous addition of sucrose (Suc) prevented the reduction in enzyme activities, but not in mRNA levels. OAS, a known regulator of sulfate assimilation, could also attenuate the effect of missing CO(2) on APR, but did not affect NR. When the plants were subjected to normal air after a 24-h pretreatment in air without CO(2), APR and NR activities and mRNA levels recovered within the next 24 h. The addition of Suc and glucose in air without CO(2) also recovered both enzyme activities, with OAS again influenced only APR. (35)SO(4)(2-) feeding showed that treatment in air without CO(2) severely inhibited sulfate uptake and the flux through sulfate assimilation. After a resupply of normal air or the addition of Suc, incorporation of (35)S into proteins and glutathione greatly increased. OAS treatment resulted in high labeling of cysteine; the incorporation of (35)S in proteins and glutathione was much less increased compared with treatment with normal air or Suc. These results corroborate the tight interconnection of sulfate, nitrate, and carbon assimilation.  (+info)

Fatty acid composition of Dracunculus vulgaris Schott (Araceae) seed oil from Turkey. (3/90)

Dracunculus vulgaris Schott is only one taxon of the genus Dracunculus (Araceae) in Turkey. The tubers and the fruits with the seeds of D. vulgaris have long been in use for the treatment of rheumatism and hemorrhoids, respectively. The fatty acid composition of D. vulgaris seeds have been analyzed as their methyl esters by GC and GC-mass spectrometry. C16:0, C16:1n-7, C18:1n-9, C18:1n-7 (cis -vaccenic acid), C18:2n-6 and 13-phenyl tridecanoic acids were found to be the main components in the seed oil.  (+info)

Identification of Streptomyces coelicolor proteins that are differentially expressed in the presence of plant material. (4/90)

Streptomyces coelicolor and Lemna minor were used as a model to study the modulation of bacterial gene expression during plant-streptomycete interactions. S. coelicolor was grown in minimal medium with and without L. minor fronds. Bacterial proteomes were analyzed by two-dimensional gel electrophoresis, and a comparison of the two culture conditions resulted in identification of 31 proteins that were induced or repressed by the presence of plant material. One-half of these proteins were identified by peptide mass fingerprinting by using matrix-assisted laser desorption ionization-time of flight mass spectrometry. The induced proteins were involved in energetic metabolism (glycolysis, pentose phosphate pathway, oxidative phosphorylation), protein synthesis, degradation of amino acids, alkenes, or cellulose, tellurite resistance, and growth under general physiological or oxidative stress conditions. The repressed proteins were proteins synthesized under starvation stress conditions. These results suggest that root exudates provide additional carbon sources to the bacteria and that physiological adaptations are required for efficient bacterial growth in the presence of plants.  (+info)

Isolation of a crystal matrix protein associated with calcium oxalate precipitation in vacuoles of specialized cells. (5/90)

The formation of calcium (Ca) oxalate crystals is considered to be a high-capacity mechanism for regulating Ca in many plants. Ca oxalate precipitation is not a stochastic process, suggesting the involvement of specific biochemical and cellular mechanisms. Microautoradiography of water lettuce (Pistia stratiotes) tissue exposed to 3H-glutamate showed incorporation into developing crystals, indicating potential acidic proteins associated with the crystals. Dissolution of crystals leaves behind a crystal-shaped matrix "ghost" that is capable of precipitation of Ca oxalate in the original crystal morphology. To assess whether this matrix has a protein component, purified crystals were isolated and analyzed for internal protein. Polyacrylamide gel electrophoresis revealed the presence of one major polypeptide of about 55 kD and two minor species of 60 and 63 kD. Amino acid analysis indicates the matrix protein is relatively high in acidic amino acids, a feature consistent with its solubility in formic acid but not at neutral pH. 45Ca-binding assays demonstrated the matrix protein has a strong affinity for Ca. Immunocytochemical localization using antibody raised to the isolated protein showed that the matrix protein is specific to crystal-forming cells. Within the vacuole, the surface and internal structures of two morphologically distinct Ca oxalate crystals, raphide and druse, were labeled by the antimatrix protein serum, as were the surfaces of isolated crystals. These results demonstrate that a specific Ca-binding protein exists as an integral component of Ca oxalate crystals, which holds important implications with respect to regulation of crystal formation.  (+info)

Genetic relationships of Aglaonema species and cultivars inferred from AFLP markers. (6/90)

BACKGROUND AND AIMS: Aglaonema is an important ornamental foliage plant genus, but genetic relationships among its species and cultivars have not been reported. This study analysed genetic relatedness of 54 cultivars derived from nine species using amplified fragment length polymorphism (AFLP) markers. METHODS: Initially, 48 EcoRI + 2/MseI + 3 primer set combinations were screened, from which six primer sets that showed clear scoreable and highly polymorphic fragments were selected and used for AFLP reactions. AFLP fragments were scored and entered into a binary data matrix as discrete variables. Jaccard's coefficient of similarity was calculated for all pair-wise comparisons among the 54 cultivars, and a dendrogram was constructed by the unweighted pair-group method using the arithmetic average (UPGMA). KEY RESULTS: The number of AFLP fragments generated per primer set ranged from 59 to 112 with fragment sizes varying from 50 to 565 bp. A total of 449 AFLP fragments was detected, of which 314 were polymorphic (70 %). All cultivars were clearly differentiated by their AFLP fingerprints. The 54 cultivars were divided into seven clusters; cultivars within each cluster generally share similar morphological characteristics. Cluster I contains 35 cultivars, most of them are interspecific hybrids developed mainly from A. commutatum, A. crispum or A. nitidum. However, Jaccard's similarity coefficients among these hybrids are 0.84 or higher, suggesting that these popular hybrid cultivars are genetically much closer than previously thought. This genetic similarity may imply that A. nitidum and A. crispum are likely progenitors of A. commutatum. CONCLUSIONS: Results of this study demonstrate the efficiency and ease of using AFLP markers for investigating genetic relationships of ornamental foliage plants, a group usually propagated vegetatively. The AFLP markers developed will help future Aglaonema cultivar identification, germplasm conservation and new cultivar development.  (+info)

Effects of a PAL inhibitor on phenolic accumulation and UV-B tolerance in Spirodela intermedia (Koch.). (7/90)

Duckweed (Spirodela intermedia) was grown axenically on 1/2 strength Hutner's nutrient solution plus 1% sucrose, with the l-phenylalanine ammonia-lyase (PAL) inhibitor 2-aminoindan-2-phosphonic acid (AIP) at 0.0, 0.05, or 10 microM, at constant 25 degrees C and a light intensity of 300 micromol m(-2) s(-1) photosynthetically active radiation from CW fluorescent lamps. Growth with 10 microM AIP led to decreased frond area and fresh weight, but dry weight was unchanged. Microscopic examination of fronds revealed increased frond thickness and a lack of reticulate aerenchyma. Ultraviolet epifluorescence microscopy and UV-Vis spectroscopy of methanolic extracts confirmed the dose-dependent inhibition of secondary phenolic synthesis with the near total elimination of secondary phenolic accumulation at the 10 microM level. AIP-treated plants showed increased sensitivity to UV-B as shown by a reduced F(v)/F(m). The results provided direct evidence of the working hypothesis that phenols function to screen UV radiation from reaching photosynthetic tissues or damaging other sensitive tissues. A novel histochemical method employing zirconyl chloride to visualize phenols is discussed.  (+info)

Coronamycins, peptide antibiotics produced by a verticillate Streptomyces sp. (MSU-2110) endophytic on Monstera sp. (8/90)

Coronamycin is a complex of novel peptide antibiotics with activity against pythiaceous fungi and the human fungal pathogen Cryptococcus neoformans. It is also active against the malarial parasite, Plasmodium falciparum, with an IC(50) of 9.0 ng ml(-1). Coronamycin is produced by a verticillate Streptomyces sp. isolated as an endophyte from an epiphytic vine, Monstera sp., found in the Manu region of the upper Amazon of Peru. Bioassay-guided fractionation of the fermentation broths of this endophyte on silica gel and HPLC chromatography yielded two principal, inseparable, peptides with masses of 1217.9 and 1203.8 Da. Three other minor, but related components, are also present in the preparation. Amino acid analysis of coronamycin revealed residues of component 1, component 2, methionine, tyrosine and leucine at a ratio of 2:2:1:1:3. Other compounds with antifungal activities are also produced by this endophytic streptomycete.  (+info)

Pistia stratiotes, commonly called water lettuce, is a free-floating, frost-tender aquatic perennial that is commonly used as an ornamental plant in water gardens. It produces rosettes (4-6" across) of wedge-shaped, overlapping, fluted, velvety, soft green leaves covered with water-repellant hairs. Plants resemble small open heads of lettuce. New plants are formed at the ends of stolons radiating outward from the mother plant. Plants can spread rapidly to form dense mats of foliage (to 4" tall), and are considered to be noxious weeds in many tropical and sub-tropical areas where they can quickly cover a pond or lake from shore to shore. Tubular, axillary, arum-like, yellowish-green to creamy white flowers are generally inconspicuous. Flowers give way to similarly inconspicuous green berry-like fruits. Feathery roots dangle downward from the plants, providing a shelter for many small fish. As an ornamental plant, water lettuce provides attractive foliage that inhibits growth of algae and helps ...

On June 27, organized by the Ministry of Agriculture, the National Invasive Species Eradication Activities had been started in Xincheng County, Laibin City, Guangxi Province with the beginning of the removal of Pistia Stratiotes. The theme was "eradicating alien creatures, and build a beautiful homeland." After the ceremony, the participants came to the Xincheng County and begun the eradication of Pistia stratiotes in Shilong village.. Pistia stratiote is also known as "pig grass", "lettuce", because of its shape looks like a Chinese cabbage, it is also known as "water cabbage." Pistia stratiote was imported from Brazil in the 1950s as pig feed in China to promote pig cultivation. The "Water cabbage" can grow quickly in calm freshwater lakes, reservoirs, ditches and can clog waterways affecting aquaculture, resulting in death of submerged plants, bringing harm to aquatic ecosystems. ...

The influence of ethylenediaminetetraacetic acid (EDTA) and chemical species on arsenic accumulation in aquatic floating macrophyte Spirodela polyrhiza L. (duckweed) was investigated. The uptake of inorganic arsenic species (arsenate; As(V) and arsenite; As(III)) into the plant tissue and their adsorption on iron plaque of plant surfaces were significantly (p,0.05) higher than those of organic species (monomethylarsonic acid (MMAA) and dimethylarsinic acid (DMAA)). The addition of EDTA to the culture media increased the uptake of As(V) and As(III) into the plant tissue though the MMAA and DMAA uptake were not affected. About 46% of the inorganic arsenic species were desorbed or mobilized from iron plaque by EDTA. Desorption of organic arsenic species was not affected by EDTA addition because the co-precipitation occurs only with inorganic species. Phosphate uptake was not affected by EDTA though its concentration in citrate-bicarbonate-EDTA (CBE)-extract was much higher than that of plant ...
High arsenic (As) concentrations are toxic to all the living organisms and the cellular response to this metalloid requires the involvement of cell signaling agents, such as nitric oxide (NO). The As toxicity and NO signaling were analyzed in Pistia stratiotes leaves. Plants were exposed to four treatments, for 24 hours: control; SNP (sodium nitroprusside (NO donor); 0.1 mg L-1); As (1.5 mg L-1) and As + SNP (1.5 and 0.1 mg L-1, respectively). The absorption of As increased the concentration of reactive oxygen species (ROS) and triggered changes in the primary metabolism of the plants. While photosynthesis and photorespiration showed sharp decrease, the respiration process increased, probably due to chemical similarity between arsenate and phosphate, which compromised the energy status of the cell. These harmful effects were reflected in the cellular structure of P. stratiotes, leading to the disruption of the cells and a possible programmed cell death. The damages were attenuated by NO, which was able

Commonly called Chinese evergreen, Aglaonema is one of the most widely used foliage plants due to its ability to tolerate low light and low humidity, and its resistance to diseases and pests. This crop has been commercially cultivated in Florida since the 1930s. The genus Aglaonema includes 21 species native to Southeast Asia. In the wild, Aglaonema species are open-pollinated. The base number of chromosomes is 2n = 6, with subsequent polyploidy in many cases.. Aglaonema hybrids for ornamental foliage production are almost exclusively developed via interspecific hybridization within traditional breeding programs. The species A. nitidum, A. commutatum, A. costatum, and A. rotundum are commonly used in the interspecific hybridization work. Current breeding activities focus on generating novel foliage variegation patterns, new petiole colors, increased branching, and better chilling resistance.. Popular hybrids from the breeding program at the University of Floridas MREC in Apopka include ...

Aglaonema have been grown as luck-bringing ornamental plants in Asia for centuries.[3] They were introduced to the West in 1885,[3] when they were first brought to the Royal Botanic Gardens, Kew.[4] They have been cultivated, hybridized, and bred into a wide array of cultivars. They live in low-light conditions and are popular houseplants.[3] This mainly tropical genus is known for its intolerance of cold temperatures. Chilling injury can begin at 59 °F (or 15 °C).[5] The injury manifests in dark, greasy-looking patches on the foliage.[5] Cultivars have been selected for their shape and size, and especially for the color and pattern of the leaves. Many have white or cream-colored stems. Some have also been developed to tolerate colder temperatures.[3] The most common cultivar is Silver Queen,[3] which has gained the Royal Horticultural Societys Award of Garden Merit.[6] Most propagation of Aglaonema is done with cuttings and by dividing the basal shoots. Care of the houseplant involves ...

Anthurium plowmanii is an evergreen plant belonging to the pant Family Araceae. It is said to have originated from South America. It has become very popular in Indonesia and fetches high price when sold as ornamental plant. It is said that the more ruffled the leaf perimeter is, the higher is the price tag on it. The love for the ruffle has earned the plant the nickname "Gelombang Cinta", which means "Wave of Love". In Malaysia the craze for this plant is not obvious ...

Short chain ω-phenylalkanoic acids have long been known to occur in natural products. Phenylacetic, 3-phenylpropanoic and 3-phenylpropenoic (cinnamic) acids are found in propolis, mammalian exocrine secretions or plant fragrances. During a systematic study of the lipids from seeds of the plant Araceae, the presence of 13-phenyltridecanoic acid as a major component (5-16% of total fatty acids)was discovered. Other similar compounds but with 11 and 15 carbon chain lengths and saturated or unsaturated were shown to be also present but in lower amounts. At the same time, the even carbon chain ω-phenylalkanoic acids of C10 up to C16 were discovered in halophilic bacteria. Later, an exhaustive study of 17 genus of the subfamily Aroideae of Araceae revealed the presence of three major acids, 11-phenylundecanoic acid, 13-phenyltridecanoic acid and 15-phenylpentadecanoic acid in seed lipids. Other odd carbon number acids from C7 to C23 were detected but in trace amounts. Similarly, two series of ...
We aimed to analyze the rheological characteristics during elongation of the root segments in Lemna minor. The elastic component of segment elongation (EC) increased for the first 6 h, and then almost stopped. However, the plastic component of the segment elongation (PC) began to rapidly increase from 6 h onwards. Uniconazole-P, a gibberellin biosynthesis inhibitor, inhibited the total elongation of root segments (TE), and this inhibition was mainly caused by suppression of the rapid increase in the PC after 6 h. Concomitant with this inhibition, the cortical microtubule (CMT) array within root epidermal cells became disorganized in the presence of uniconazole-P from 6 h onwards. Adding GA3 abolished the inhibition of TE by uniconazole-P treatment, and this recovery was caused not by the increase in the EC but by an increase in the PC. Furthermore, the CMT arrays also recovered their characteristic organization in the presence of GA3. These findings suggest that endogenous gibberellin ...
The swamp or skunk cabbage (Symplocarpus foetidus) emerged a couple of weeks ago down at the stream. I had read that it provides one of the earliest sources of pollen in the spring and I was curious if my bees were taking part. Upon closer scrutiny I indeed found many bees flying in, crawling deep into the dark purplish curled hood and then off again to the hive to store the pollen. The foul odor attracts the bees and inside they may find a cozy temperature reaching into the 80s. After knee deep in mud and patiently awaiting for a bee to emerge, I captured this great shot. If you click on the picture, you can see the bee at the tip.. ...
A contaminação dos ecossistemas aquáticos pelo manganês (Mn) está associada, em grande escala, as ações antrópicas como, processos de manufatura de papel, resíduos de mineração e resíduos de esgoto domésticos. A fitorremediação consiste na utilização de plantas, dentre as quais as macrófitas aquáticas, com potencial para remover, degradar ou inativar contaminantes orgânicos e inorgânicos do meio, minimizando seus efeitos sobre os organismos vivos e o ambiente. O presente estudo avaliou o potencial fitorremediador de três espécies de macrófitas aquáticas: Azolla caroliniana, Salvinia minima e Spirodela polyrhiza para acumular Mn em solução. O acúmulo de Mn, o crescimento, o conteúdo de clorofila total e carotenóides foram avaliados nas três espécies submetidas a concentrações crescentes (0,05; 0,1; 0,2; 03; 0,4 mM) de Mn. As três espécies de macrófitas acumularam Mn em seus tecidos e a absorção foi dependente da concentração do metal em solução. As ...

Ive dabbled with a few Colocasias in the past and grew an impressive Jacks Giant two summers ago. This year I seem to have seen them and their relatives everywhere from chilly Norfolk in the UK to the sunshine of New York. Inevitably Will Giles had a some in his exotic garden including some great Xanthosomas in his new polythene tunnel. Not surprisingly there was a good selection at the Brooklyn Botanic Garden and a few in the Conservatory Gardens in Central Park. What did surprise me was their usage in planters in public areas. I wonder if this would work in the UK? I somehow doubt we would have enough sunshine and warmth to encourage them to really thrive! Anyway heres a few pictures to show you what has grabbed my attention. Naming may be a bit hit and miss as some inevitably werent labelled. If you have a better guess - let me know or leave a comment! First some Alocasias - probably the most difficult to grow. ...

To understand the reason behind this mystery, a team of plant researchers headed by Dr. Meret Huber from the Max Planck Institute for Chemical Ecology in Jena and the University of Münster measured the mutation rate of this duckweed under outdoor conditions, i.e. how many mutations accumulate per generation. The result: low genetic diversity in this plant was accompanied by an extremely low mutation rate. "Our study emphasizes that accurate estimates of mutation rates are important for explaining patterns of genetic diversity among species," says Meret Huber. The results are not only relevant for future studies on the evolution of plants, including many crops that have similar reproductive strategies like duckweeds, they will also accelerate the use of duckweeds both for basic research and industrial applications. The study was published in the journal Nature Communications ...

ABSTRACT: The bivalve mollusc Corbula gibba (Olivi) is often regarded as an invasive weed species that forms monospecific stands in organically enriched hypoxic habitats. However, despite its status as a potential menace, surprisingly little is known about its basic biology, including its dispersal capacity. Measurement of the respiration rate of C. gibba revealed a respiratory demand of 3.12 µl O2 h 1 and a respiratory quotient of 0.61, which suggests that C. gibba adopts a conservationist rather than exploitative mode of life. Examination of the hypoxic tolerance of C. gibba determined that adults could survive for ,34 d (LT50 ≥ 34 d) and juveniles for ,30 d (LT50 = 14 d), indicating that this species is well adapted to living in low oxygen habitats. Unusually, adults under hypoxia had a greater survival rate than control adults in normoxic conditions. Investigation of the salinity tolerance of C. gibba revealed that it could readily survive for 2 d at 0 to 16 psu, with increasing mortality ...
Skillicorn recommended that Hookerton install 26 greenhouses, each 100-feet-by-15 feet. Untreated waste from the first lagoon would enter the greenhouses, where duckweed would feed off nutrients in the waste, growing rapidly. Nutrients dumped into rivers and streams generate algae blooms that rob waters of oxygen, hurting plant and animal life. But under Skillicorns plan, duckweed would break down the nutrients while removing those pollutants from the water ...
Fortunately, the wayward hummer appeared at the home of Tania and Corey Perry. Tania is a birder, and knew right away that the hummingbird was something special. For a while, the identification was up in the air, which isnt surprising. The Calliope Hummingbird used to be placed in its own genus, Stellula, but has recently been submerged into the genus Selasphorus, which includes Allens, Broad-tailed, and Rufous hummingbirds. The latter two, especially, are quite similar to the Calliope in subadult plumage. Rufous is the default vagrant hummingbird here, with dozens of records and birds turning up annually. There is but one Ohio record of Allens Hummingbird, from late fall/early winter 2009. Ditto the Calliope Hummi ...

We assessed the effect of two biological control agents, the mirid Eccritotarsus catarinensis (Carvalho) and the weevil Neochetina eichhorniae (Warner), singly or in combination, on the competitive ability of their host plant, water hyacinth, Eichhornia crassipes (Mart.) Solms-Laub., grown in a screen house, in competition with another aquatic plant (Pistia stratiotes L.). Water hyacinth plant growth characteristics measured included fresh weight, leaf and petiole lengths, number of inflorescences produced, and new shoots. Without herbivory, water hyacinth was 18 times more competitive than water lettuce (across all experimental combinations of initial plant densities), as estimated from fresh weights. Both insect species, singly or in combination, reduced water hyacinth plant growth characteristics. E. catarinensis alone was less damaging than the weevil and under normal conditions, i.e., floating water hyacinth, is not expected to increase control of water hyacinth beyond that of the weevil. ...
The origin, development and formation of foliage-leaf-patterns could be explained with selected variegaten forms of the Araceae, Asteraceae, Ericaceae, Marantaceae and Rosaceae. In order to prove this the plants were examined according to the problem and classified in three different groups: In the first group, leaf-patterns with irregular maculated patterns, Monstera deliciosa, Syngonium podophyllum and the sorts Pirol and Luyona of Dendranthema grandiflorum showed an irregular foliage-leaf-pattern, thought neither to show periclinal chimeras with white edges nor with green edges. Mixed cells were detected by direct (microscopic) and indirect (In vitro culture and self pollination) test. After the plastid sorting out in the layers of the meristems, the green over white Form was proven with Syngonium, Monstera and the two sorts of Dendranthema as a single stable periclinal chimera. In the second group, eversporting periclinal chimeras, the green over aurea chimeral constitution with Spiraea ...

Abstract: Cancer cells have a relatively high telomerase activity compared to normal cells, so that cancer cells have the ability for continued proliferation and uncontrolled mitosis. Telomerase is an enzyme responsible for the length of telomeres, DNA segments located at the ends of eukaryotic chromosomes. Natural materials such as rodent tuber (Typhonium flagelliforme) have anticancer potential. The purpose of the present study was to determine the effects of Typhonium flagelliforme extract on telomerase expression in HeLa cervical cancer and T47D breast cancer cells. ...

Amorphophallus paeoniifolius occurs through the tropics, from India to New Guinea and to Australia where it is found in tropical Queensland and Northern Territory in seasonally dry areas. The species was previously called Amorphophallus campanulatus.. This plant produces a single inflorescence followed by a solitary leaf. The plant is deciduous, dying back to a large underground corm, weighing up to 8kg, after the growing season.. Some people regard the inflorescence as bizarre. It comprises a large spadix crowned with a bulbous purple knob, encircled by a fleshy purple and green-blotched spathe up to 50cm wide. On successful pollination of the female flowers the spadix can extend to 2m tall. The fresh inflorescence emits an odor reminiscent of rotting flesh to attract pollinating carrion flies and beetles.. The solitary leaf resembles a small tree. The leaf blade is much divided into hundreds of leaflets and can reach over 1m wide. This blade sits atop a thick fleshy stem up to 13cm diameter ...
Araceae are herbs with leaves that are usually divided into a petiole and expanded blade. They have a distinctive inflorescence of a more or less petal-like spathe plus a spadix made up of densely-packed, sessile, ebracteate flowers - in many taxa the spadix has a large, terminal, sterile part. The fruit is a berry. Evolution: Divergence & Distribution. Mayoa pollen grains that look very like those of Monsteroideae have been found in Early Cretaceous deposits of the late Barremian-early Aptian of some 120-110 Ma in Portugal (Friis et al. 2004; see also Hesse & Zetter 2007). Although the identity of some of these grains has been questioned (Hoffmann & Zetter 2010), macrofossils apparently of staminate flowers belonging to Aroideae (a decidedly non-basal clade) have been discovered in slightly younger deposits ca 112 Ma and also in Portugal (Friis et al. 2010: c.f. pollen; Friis et al. 2011; Isles et al. 2015). Thus the fossil record would suggest that all eight subfamilies of Araceae may have ...
Today, many once-popular horticultural trends are just as passé as swim-tops for men and iceberg lettuce in a salad. Remember when everybody had an air plant pinned to the curtains in most rooms of the house and gardeners were happy to have plain white petunias? If you dont recall those days of yore, you certainly will not remember the popularity once surrounding the Monstera deliciosa, or Swiss-cheese plant.

The botanical name, Monstera, is Latin for strange or monstrous, and points to some of the oddities associated with this rambling vine. These include aerial roots and large, glossy leaves full of deeply lobed cutouts and neatly cut round or oval holes, hence the common name Swiss-cheese plant.
With tunes like "someone", "saussurea" and "monstera", this EP has the essence of a night out, while keeping things from getting too clubby which makes the recording an enjoyment in your room, car, iPod or wherever you prefer to partake.. Only a DJ/Producer with the experience of veteran can be mature enough to craft a collection of tunes that seem as if they were meant to have been mixed back to back while keeping things interesting enough to lock a listener in for the entire listen.. The odd thing here is that the veteran in question, Jarradcleofé, seems to still be very young. But that doesnt stop him from producing like a veteran!. All of the productions on this EP are virtually perfect in form, melody, style and groove in my opinion. That is much more than I could say in many of my recent electronic review contributions. In a period where the number of progressive releases seems endless, there often comes along one recording that blows everything else out of the water, "monstera" is one ...
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.

The plant |i |Typhonium flagelliforme|/i|, commonly known as “rodent tuber” in Malaysia, is often used as a health supplement and traditional remedy for alternative cancer therapies, including leukemia. This study aimed to evaluate |i |in vitro|/i| anti-leukemic activity of dichloromethane extract/fraction number 7 (DCM/F7) from |i |T. flagelliforme|/i| tuber on human T4 lymphoblastoid (CEMss) cell line. The DCM extract of tuber has been fractionated by column chromatography. The obtained fractions were evaluated for its cytotoxicity toward CEMss cells as well as human primary blood lymphocytes (PBLs). Assessment of apoptosis produced by the most active fraction was evaluated by various microscopic techniques and further confirmation of apoptosis was done by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Phytochemical screening was done by gas chromatography-mass spectrometry (GC-MS). The results shows that 7 out of 12 fractions showed significant

The most surprising find was insight into the molecular basis for genes involved in maturation - a forever-young lifestyle," said senior author Joachim Messing, director of the Waksman Institute of Microbiology at Rutgers University.. S. polyrhiza leaves resemble cotyledons, embryonic leaves inside plant seeds that become the first leaves after germination. But where other plants develop other kinds of leaves as they mature, S. polyrhizas never progresses and continuously produces cotyledon leaves. This prolonging of juvenile traits is called "neoteny." S. polyrhiza had fewer genes to promote and more genes to repress the switch from juvenile to mature growth.. "Because of the reduction in neoteny, there is an arrest in development and differentiation of organs. So this arrest allowed us to uncover regulatory networks that are required for differentiation and development," Messing said.. Also intriguing to the research team were which genes were preserved over time and which were not. Many of ...

The sources of the toxic gas formaldehyde are building materials including carpeting, curtains, plywood, and adhesives.. As it is emitted, it deteriorates the air quality, which can lead to multiple chemical sensitivity and sick building syndrome, medical conditions with symptoms such as allergies, asthma, and headaches.. The prevalence of formaldehyde and other volatile organic compounds (VOC) is greater in new construction.. In the study, lead author Kwang Jin Kim of Koreas National Horticultural Research Institute compared the absorption rate of two types of houseplants, Weeping Fig (Ficus benjamina) and Fatsia japonica, an evergreen shrub.. During the study, equal amounts of formaldehyde were pumped into containers holding each type of plant in three configurations: whole, roots-only with the leafy portion cut off, and aerial-only, with the below-ground portion sealed off, leaving the stem and leaves exposed. The results showed the combined total of aerial-only and roots-only portions ...

Typhonium trilobatum, T. flagelliforme, T. roxburghii, and T. blumei are taxonomically distinct, but their epithets (including that of T. divaricatum, nom. illegit.) frequently have been interchanged, primarily because of nomenclatural problems involving synonymy and (mis)typifications. It is concluded that the last monographer (Engler, 1920) used the correct names for the four species, except for what he called T. divaricatum, here called T. blumei ...
Simple and primitive, a duckweed plant consists of a single small kidney-shaped leaf about the size of a pencil-top eraser that floats on the surface of the water with a few thin roots underwater. It grows in almost all geographic areas, at nearly any altitude. Although its a flowering plant, it only rarely forms small indistinct flowers on the underside of its floating leaves. Most of the time, it reproduces by budding off small leaves that are clones of the parent leaf. It often forms thick mats on the edges of ponds, quiet inlets of lakes and in marshes. Its among the fastest growing plants, able to double its population in a couple of days under ideal conditions.. These and other properties make it an ideal candidate as a biofuel feedstock - a raw source for biofuel production.

IMPORTANT!. Our conscious level of pain or discomfort during a cryotherapy treatment is not a benchmark to the efficiency of the treatment.. Clinical studies show that cryotherapy works efficiently under temperatures of -166 degrees Ferhenight (-110°C).. On the other hand, the more even cold distribution around the body the more pleasant the session is. Nonetheless, the physiological response that we seek is triggered when our bodys receptor feels endangering temperatures. Here is why…. How Do React to Change in Temperature?. We have a built-in sensory system for perceiving temperature.. Being a warm-blooded (or homeothermic) animal, we humans have a built-in sensory process (called thermo-reception) by which we detect different levels of temperatures in the environment and the body. This process helps us to maintain considerable inner physiological stability (e.g., body temperature and metabolism) under changing environmental conditions.. Thermal Body Sensors. Different sensors perceive ...

Chinese evergreens (Aglaonema cvv.) are one of the best plants in this situation. Though the stems do eventually get leggy (bare at the bottom, with a tuft of leaves at the top), theyre slow-growing enough that it takes quite a while for that to happen, and when things reach that point, you can cut off the tops and the base will usually produce new shoots. Though that also takes a while, so I wouldnt recommend cutting all the stems back simultaneously. They wont lose variegation in low light, and there are way more than 21 varieties. (I dont recommend the pink/red varieties like Sparkling Sarah, as those seem to need more light and heat than what youll have available, but the varieties with white or cream-colored petioles like Brilliant, Cory, Golden Bay, and Peacock are just as easy as the green-petiole types like Diamond Bay, Silver Queen, B. J. Freeman, etc., and give a more colorful impression.) Dumb cane (Dieffenbachia cvv.) looks similar but doesnt age nearly as well, ...

Our garden wildlife pond has become, fairly rapidly, full of green slime...horrid wispy (and more solid) trails, like veils under the surface and floating islands. The surface is also covered by bubbles - the bottom of the pond seems to be fermenting! Last year there was masses of oxygenating pond weed in the deeper half but its as if its all died and is decomposing. I know theres a fair amount of sludge at the bottom, and yes, we have at times allowed our ducks to have access, tho its been mostly duck-free for over a year. The shallower half of the pond has a good coverage of pond plants which seem to be fine, albeit with much duckweed amongst the foliage. There are loads of newts. Any ideas, pond-people???

Herbs, perennial, wetland, usually with aromatic oil, especially in rhizomes. Rhizomes horizontal, creeping at or near surface, branched. Stems repent, branched rhizomes. Cataphylls absent. Leaves not differentiated into petiole and blade, equitant, sword-shaped, larger than 1.5 cm; venation parallel along length of leaf. Inflorescences: spadices, from 3-angled axis (peduncle fused with proximal portion of sympodial leaf, i.e., leaf encircling terminal inflorescence), distal sympodial leaf extending beyond spadix; true spathe absent; spadix nearly cylindric, tapering, apex obtuse. Flowers bisexual; tepals 6; stamens 6, distinct; ovariesy 1, (1--)3-locular, sessile; stigmas sessile (styles essentially absent), minute. Fruits berries; pericarp thin, leathery. Seeds 1--6(--14), from apex of locule. Acorus historically was recognized as an aberrant genus within Araceae, but much evidence supports its treatment as a separate family and the removal of this family from Arales (M. H. Grayum 1987).

Monocots, or monocotyledons, are a class of the flowering plants, or angiosperms. Monocots are named for and recognized by the single cotyledon , or seed leaf, within the seed. The first green blade emerging from the seed upon germination is the cotyledon, which contains sugars and other nutrients for growth until the leaf is able to photosynthesize. Monocots comprise about 67,000 species, or one-quarter of all flowering plants. They include not only the very large grass family (Poaceae, 9,000 species), but also the orchid family (Orchidaceae, 20,000 species), and the sedge family (Cyperaceae, 5,000 species), as well as palms, lilies, bromeliads (including pineapple), and the Araceae, which includes skunk cabbage and philodendron. The angiosperms have traditionally been divided into monocots and dicots alone, but recent work has shown that while monocots form a natural evolutionary group, dicots do not, and so the angiosperms are now grouped into monocots, eudicots , and basal angiosperms. In ...
The verses in the prophets (op. cit.) clearly indicate the value of calamus and the fact that it was widely traded with nations in Asia. Two plants have been suggested. The first is a widespread plant of wetlands in the northern hemispheres of both the Old and New Worlds, Acorus calamus L. (Araceae). The rhizome has a peculiar sweet, lingering aroma suitable as a "carrier" in a perfume. Motley (1994) suggests that A. calamus is the calamus mentioned in Exodus 3 for the anoint ing oil applied to priests and objects in the tabernacle. Milne and Milne (1967) state that A. calamus was found in the tombs of the Pharaohs but cite no reference. Acorus calamus is not listed in a modern treatment of perfumery (Calkin and Jellinek 1994) but is still used in medicine and cosmetics (Leung and Foster 1996 ...

The activity of pyrophosphate:fructose-6-phosphate 1-phosphotransferase [PFK (PPi); EC 2.7.1.90] in extracts of the storage tissues of leek (Allium porrum), beetroot (Beta vulgaris) and roots of darnel (Lolium temulentum) exceeded 0.15 mumol/min per g fresh wt. As net flux from fructose 1,6-bisphosphate to fructose 6-phosphate in these tissues is unlikely, it is suggested that PFK (PPi) does not contribute to gluconeogenesis or starch synthesis. The maximum catalytic activities of PFK (PPi) in apex, stele and cortex of the root of pea (Pisum sativum) and in the developing and the thermogenic club of the spadix of cuckoo-pint (Arum maculatum) were measured and compared with those of phosphofructokinase, and to estimates of the rates of carbohydrate oxidation. PPi and fructose 2,6-bisphosphate in Arum clubs were measured. The above measurements are consistent with a glycolytic role for PFK (PPi) in tissues where there is marked biosynthesis, but not in the thermogenic club of Arum. The possibility ...

Bartonella quintana (BQ) is a gram-negative human pathogen that causes serious and potentially fatal infections, and is the leading cause of culture-negative heart valve infection in the US. BQ also causes persistent bacteremia and fatal illness in immunocompromised individuals with cancer and HIV/AIDS. BQ is transmitted to humans by the body louse; humans become infected when the BQ bacteria in the louse feces are introduced into the louse bite wound by scratching. BQ alternates between two very different niches: the bloodstream of the homeothermic mammalian reservoir (37C) and the gut of the poikilothermic arthropod vector (28C). Virtually nothing is known about the virulence factors involved in the transition between the host and arthropod vector. However, the arthropod niche is an essential part of the life cycle of BQ, and it is required for infection of humans. To surviv and proliferate, BQ bacteria must adapt rapidly during the shift between these two disparate environments. Such ...

As gunerídeas são um grande grupo de eudicotiledóneas que haviam sido nomeadas informalmente como «núcleo das eudicotiledóneas» ou «eudicotiledóneas nucleares» (em inglés "core eudicots") por quase todos os trabalhos sobre filogenia das angiospérmicas. Compreendem um grupo extremamente amplo e diverso de angiospérmicas, com uma grande variabilidade no hábito, morfologia, química, distribuição geográfica e outros atributos. A sistemática clássica, baseada unicamente em informação morfológica, não foi capaz de reconhecer este grupo. Como tal, a circunscrição das gunerídeas como um clado é baseada numa forte evidencia a partir de dos dados de análises moleculares.[25][26][27] A composição do clado é a seguinte: Gunnerales, Berberidopsidales (incluindo Aextoxicaceae),[28][29]Dilleniaceae, Santalales, Saxifragales, Vitaceae e todos os clados de Asteridae, Caryophyllales e Rosidae.
