Biosynthetic pathway of insect juvenile hormone III in cell suspension cultures of the sedge Cyperus iria. (1/20)
In most insect species, juvenile hormones regulate critical physiological processes such as metamorphosis and reproduction. In insects, these sesquiterpenoids are synthesized by retrocerebral endocrine organs, the corpora allata, via the classical mevalonate (MVA) pathway. One of these compounds, juvenile hormone III (JH III), has also been identified in the sedge Cyperus iria. In higher plants, biosynthesis of the sesquiterpenoid backbone may proceed through two distinct pathways: the MVA pathway or the 2C-methyl erythritol 4-phosphate pathway or through a combination of both pathways. Cell suspension cultures of C. iria were used to elucidate the biosynthetic pathway of JH III in the plant. Enzyme inhibition and labeling studies conclusively demonstrated that the biosynthesis of the sesquiterpenoid backbone of JH III proceeds via the MVA pathway. Inhibitor and precursor feeding studies also suggest that later steps of JH III biosynthesis in C. iria are similar to the insect pathway and that the final enzymatic reaction in JH III biosynthesis is catalyzed by a cytochrome P(450) monooxygenase. (+info)Oscillations of plants' stems and their damping: theory and experimentation. (2/20)
Free oscillations of upright plants' stems, or in technical terms slender tapered rods with one end free, can be modelled by considering the equilibrium between bending moments and moments resulting from inertia. For stems with apical loads and negligible mass of the stem and for stems with finite mass but without top loading, analytical solutions of the differential equations with appropriate boundary conditions are available for a finite number of cases. For other cases approximations leading to an upper and a lower estimate of the frequency of oscillation omega can be derived. For the limiting case of omega = 0, the differential equations are identical with Greenhill's equations for the stability against Euler buckling of slender poles. To illustrate, the oscillation frequencies of 25 spruce trees (Picea sitchensis (Bong.) Carr.) were compared with those calculated on the basis of their morphology, their density and their static elasticity modulus. For Arundo donax L. and Cyperus alternifolius L. the observed oscillation frequency was used in turn to calculate the dynamic elasticity modulus, which was compared with that determined in three-point bending. Oscillation damping was observed for A. donax and C. alternifolius for plants' stems with and without leaves or inflorescence. In C. alternifolius the difference can be attributed to the aerodynamic resistance of the leaves, whereas in A. donax structural damping in addition plays a major role. (+info)Symptomatology and morphology of Claviceps cyperi on yellow nut sedge in South Africa. (3/20)
Symptoms of ergot on yellow nut sedge, germination of sclerotia of the causal organism, Claviceps cyperi, and morphology of fresh specimens of the pathogen are described for the first time. The initial symptom of infection was a black sooty layer on inflorescences of infected plants due to colonization of the ergot honeydew by Cladosporium cladosporioides. Sclerotia of C. cyperi started to develop in March and April and could be discerned as small protuberances on inflorescences in the place of seed. Mature sclerotia were purplish-black. They generally remained viable for less than a year and germinated without prior cold treatment, although exposure for 21 d to 5 C before incubation significantly increased the germination rate. Under moist conditions at 24 C in the laboratory, germination commenced within 4-8 wk. Stromata took about 12 d to mature. Mature capitula were distinctly lobulate with a perithecium embedded in each lobe and a collar-like appendage around the base. Although dimensions of sclerotia, stipes, capitula, asci and ascospores were larger than in the original description, the general morphology supports treatment of C. cyperi as a distinct species.

The ethanol extract of Cyperus rotundus (EECR) was tested for possible pharmacological effects on experimental animals. EECR significantly potentiated the sleeping time of mice induced by standard hypnotics, viz. pentobarbitone sodium, diazepam, and meprobamate in a dose dependent manner. EECR showed significant analgesic properties as evidenced by the significant reduction in the number of writhes and stretches induced in mice by 1.2% acetic acid solution. It also potentiated analgesia induced by morphine and pethidine in mice. Pretreatment with EECR caused significant protection against strychnine and leptazol-induced convulsions. The behavioral studies on mice indicate CNS depressant activity of the ethanol extract of C. rotundus. (+info)Polyphasic analysis of the bacterial community in the rhizosphere and roots of Cyperus rotundus L. grown in a petroleum-contaminated soil. (8/20)
Cyperus rotundus L. is a perennial herb which was found prevailing in an area in the northeast of Brazil previously contaminated with petroleum. In order to enlarge the knowledge of microorganism-plant interaction in phytoremediation, the bacterial community present in the rhizosphere and roots of C. rotundus was evaluated by culture-dependent and molecular approaches. PCR-DGGE analyses based on the 16S rRNA gene showed that the profiles of bulk soil, rhizosphere and root samples had a high degree of similarity. A complex community of alkane utilizing-bacteria and a variable nitrogen-fixing community were observed when the PCR-DGGE analyses were based on the genes alkB and nifH, respectively. In addition, two clone libraries were generated from the alkB fragments of bulk and rhizosphere soils. Statistical analyses showed that the libraries were different concerning the alkB population composition. Using culture-dependent techniques, 209 bacterial strains were isolated from the rhizosphere and rhizoplane/roots of C. rotundus. Dot blotting analysis showed that the DNA from 17 strains hybridized, simultaneously, with the alkB and nifH probes. After partial 16S rRNA gene sequencing, these strains were affiliated with the genera Bosea, Cupriavidus, Enterobacter, Gordonia, Mycoplana, Pandoraea, Pseudomonas, Rhizobium and Rhodococcus. They can be considered of great potential for phytoremediation in this tropical soil area. (+info)In the medical field, "Cyperus" refers to a genus of plants in the family Cyperaceae, commonly known as sedges. There are over 5,000 species of Cyperus, and they are found in a wide range of habitats around the world, including wetlands, grasslands, and forests. Some species of Cyperus are used in traditional medicine for a variety of purposes. For example, the roots of Cyperus rotundus (also known as "chavica" or "gundhi") are used in Ayurvedic medicine to treat digestive disorders, while the leaves of Cyperus alternifolius (also known as "papyrus sedge") are used in traditional African medicine to treat fever and other infections. In addition to their medicinal uses, some species of Cyperus are also used in horticulture as ornamental plants. They are valued for their attractive foliage and flowers, and are often used in gardens, parks, and other outdoor spaces.
Cyperaceae is a family of monocotyledonous flowering plants commonly known as sedges. They are found in a wide range of habitats, including wetlands, grasslands, and forests. In the medical field, Cyperaceae plants are known for their medicinal properties and have been used for centuries in traditional medicine to treat various ailments. Some species of Cyperaceae are used to treat digestive disorders, respiratory problems, and skin conditions. For example, the leaves of the common sedge (Carex species) are used in traditional medicine to treat digestive problems such as diarrhea and dysentery. The roots of the yellow sedge (Cyperus esculentus) are used to treat respiratory problems such as coughs and bronchitis. The leaves of the saw sedge (Cladium jamaicense) are used to treat skin conditions such as eczema and psoriasis. However, it is important to note that the use of Cyperaceae plants for medicinal purposes should be done under the guidance of a qualified healthcare professional, as some species may have toxic effects or interact with other medications.
Amylopectin is a type of starch that is found in plants, particularly in grains such as wheat, rice, and corn. It is a complex carbohydrate made up of long chains of glucose molecules that are branched at regular intervals. In the medical field, amylopectin is often studied in relation to its role in digestion and metabolism. It is slowly broken down by digestive enzymes in the small intestine, releasing glucose into the bloodstream. This process is important for providing the body with energy. Amylopectin is also used in the production of certain medications, such as insulin, and as a thickening agent in food products. However, excessive consumption of amylopectin-rich foods has been linked to an increased risk of certain health conditions, such as type 2 diabetes and obesity.
Biological Oxygen Demand (BOD) analysis is a laboratory test used to determine the amount of oxygen required by microorganisms to decompose organic matter in a sample of water. The test is commonly used in the medical field to assess the quality of water used for drinking, irrigation, and other purposes. In the medical field, BOD analysis is often used to evaluate the effectiveness of wastewater treatment systems, as well as to monitor the quality of hospital effluent and other medical waste streams. The test can also be used to assess the potential for waterborne diseases, as high levels of organic matter in water can provide a breeding ground for harmful bacteria and other microorganisms. To perform a BOD analysis, a sample of water is collected and incubated under controlled conditions to allow microorganisms to break down the organic matter in the sample. The amount of oxygen consumed during this process is then measured, and the BOD value is calculated as the amount of oxygen required to completely oxidize the organic matter in the sample. Overall, BOD analysis is an important tool for assessing the quality of water and ensuring that it is safe for human consumption and other uses.
Amylose is a type of starch that is found in plants, particularly in grains such as wheat, rice, and corn. It is a linear chain of glucose molecules that are linked together by alpha-1,4-glycosidic bonds. Amylose is not easily digestible by humans, as it requires the action of digestive enzymes to break down the bonds between the glucose molecules. However, it can be broken down by bacteria in the large intestine, which can lead to the production of gases and other digestive symptoms. Amylose is also used in the production of certain types of medical devices, such as sutures and wound dressings, due to its ability to absorb and retain moisture.
