Carbon assimilation by Claviceps purpurea growing as a parasite. (1/48)

Carbon assimilation by Claviceps purpurea, growing as a parasite on cereals, has been investigated by supplying the host plant with 14CO2 in a closed system. The presence of the pathogen induced the plant to exude photosynthate which contained high levels of sucrose. During the period of 14CO2 supply, 14C was incorporated into the sucrose and so the path of carbon into the parasite could be traced. Hexoses, derived by the action of the fungal sucrase on sucrose, were assimilated by the pathogen and largely converted into polyols - mainly mannitol and, to a lesser extent, trehalose. The rate of carbohydrate metabolism decreased with maturation of the ergot, and also showed qualitative differences between the basal and apical regions of the ergot which were probably a function of nutrient supply.  (+info)

Identification and characterization of a tri-partite hydrophobin from Claviceps fusiformis. A novel type of class II hydrophobin. (2/48)

A new type of hydrophobin is encoded by an abundant mRNA of Claviceps fusiformis. The predicted amino-acid sequence of the protein, dubbed CFTH1, shows a putative signal sequence for secretion, followed by three class II hydrophobin domains each preceded by glycine/asparagine rich regions. SDS/PAGE analysis of 60% ethanol extractions of C. fusiformis mycelia from shaken cultures showed CFTH1 at the 50-55-kDa position. N-terminal sequencing of both untreated mature CFTH1 and of a fragment obtained by trypsin digestion revealed that CFTH1 is not processed between the hydrophobin domains. Mass spectroscopy showed a mass of about 36 500 Da, which is about 1500 Da higher than the mass predicted from the constituent amino acids, indicating post-translational modification but not glycosylation. Purified CFTH1 self-assembled at hydrophilic/hydrophobic interfaces and, after assembly at a water/air interface, it was found to be highly surface active. Antibodies raised against CFTH1 localized the protein in a mucilageous coat surrounding submerged vegetative hyphae in liquid shaken culture and, as a discrete layer of about 10 nm thickness at the surface of aerial hyphae of standing cultures, suggesting a role in the formation of aerial hyphae.  (+info)

Chemoraces and habitat specialization of Claviceps purpurea populations. (3/48)

We studied genetic variability of 100 isolates of Claviceps purpurea by using randomly amplified polymorphic DNA (RAPD), an EcoRI restriction site polymorphism in the 5.8S ribosomal DNA (rDNA), the alkaloids produced, and conidial morphology. We identified three groups: (i) group G1 from fields and open meadows (57 isolates), (ii) group G2 from shady or wet habitats (41 isolates), and (iii) group G3 from Spartina anglica from salt marshes (2 isolates). The sclerotia of G1 isolates contained ergotamines and ergotoxines; G2 isolates produced ergosine and ergocristine along with small amounts of ergocryptine; and G3 isolates produced ergocristine and ergocryptine. The conidia of G1 isolates were 5 to 8 microm long, the conidia of G2 isolates were 7 to 10 microm long, and the conidia of G3 isolates were 10 to 12 microm long. Sclerotia of the G2 and G3 isolates floated on water. In the 5.8S rDNA analysis, an EcoRI site was found in G1 and G3 isolates but not in G2 isolates. The host preferences of the groups were not absolute, and there were host genera that were common to both G1 and G2; the presence of members of different groups in the same locality was rare. Without the use of RAPD or rDNA polymorphism, it was not possible to distinguish the three groups solely on the basis of phenotype, host, or habitat. In general, populations of C. purpurea are not host specialized, as previously assumed, but they are habitat specialized, and collecting strategies and toxin risk assessments should be changed to reflect this paradigm shift.  (+info)

Metabolism of the germinating sclerotium of Claviceps purpurea. (4/48)

The concentration of free amino acids, particularly alanine, altered as stromata developed on germinating sclerotia. Lipid reserves in the sclerotium provided the principal carbon and energy source, and the nutrients required for stomatal growth appeared to be provided by the sclerotial tissues immediately beneath the point of attachment of the stoma. Alkaloid did not disappear from the sclerotia during germination. Very high levels of polyol, particularly mannitol, were attained in the stromata as germination progressed; the synthesis of polyol was usually accompanied by that of soluble sugars, notably glucose. In an attempt to ascertain the role of mannitol in germination, the relationship between polyol and soluble sugars was investigated in excised stromata after their submergence in buffered media containing a variety of soluble carbohydrates. Mannitol was synthesized under these conditions by way of phosphorylated intermediates, and chiefly in the capitulum, after rapid, and probably passive, absorption of the exogenously supplied sugar. The tissues equilibrated rapidly with the supplied carbohydrate, whose concentration was maintained by further uptake whilst mannitol was being synthesized. The concentrations of assimilated glucose and synthesized mannitol tended toward the same value during incubation and the results suggested that the synthesis was compartmentalized within the stromata. Very little exogenously supplied mannitol was assimilated.  (+info)

The biotrophic, non-appressorium-forming grass pathogen Claviceps purpurea needs a Fus3/Pmk1 homologous mitogen-activated protein kinase for colonization of rye ovarian tissue. (5/48)

Claviceps purpurea is a common pathogen of a wide range of grasses and cereals that is able to establish a stable, balanced interaction with its host plant and is considered a biotroph. It does not form special penetration structures such as appressoria. To study the signaling processes involved in this special host-pathogen interaction, we have cloned a gene, cpmk1, encoding a mitogen-activated protein (MAP) kinase that shows significant homology to Fus3 of Saccharomyces cerevisiae and to pmk1 of Magnaporthe grisea. Using a gene-replacement approach, we isolated a Acpmk1 mutant and characterized it in detail. Loss of CPMK1 has no obvious effect on vegetative properties (such as growth rate, morphology, and conidia formation); however, infection tests on rye show that the mutant is unable to colonize rye tissue, i.e., it appears to be completely nonpathogenic. Complementation of the mutant with a wild-type copy of cpmk1 fully restores its pathogenicity, confirming that this MAP kinase is essential for infection of rye by C. purpurea. Transformation of the delta pmk1 mutant of M. grisea with a complete copy of cpmk1 (including the C. purpurea promoter) fully restored its ability to form appressoria and its pathogenicity on barley. Although both fungi drastically differ in their pathogenic strategies, this result indicates that the signal pathway involving CPMK1 is highly conserved.  (+info)

Thermoregulatory response of dairy cows fed ergotized barley during summer heat stress. (6/48)

Claviceps purpurea infects the seed heads of cereal grains and grasses and produces ergopeptine alkaloids that cause hyperthermia and agalactia in cattle during periods of heat stress. A field experiment was undertaken to examine the effects of ergopeptine alkaloids found in barley on thermal status of dairy cattle during periods of heat stress. Production end points were also measured to identify the effect of the change in thermal status. Contaminated barley screenings containing known levels of ergopeptine alkaloids were fed to lactating Holstein cattle (10 microg total ergopeptine alkaloids/kg BW/day) for 10 days during summer heat stress. Air temperature increased 14.4 C during the first 8 days of treatment and then declined the same during the last 2 days. Extreme daily values for rectal temperature and respiration rate, using averages of all animals, showed maximum increases of 2.3 C and 56.8 breaths/minute, respectively, during this period. Group afternoon milk production decreased 2 kg/day during the heat stress period, with no measurable change in feed intake. A greater level of hyperthermia occurred in cattle consuming the diet with ergopeptine alkaloids, with only marginal symptoms of ergot toxicosis reflected in feed intake and milk production. Therefore, the ergopeptine alkaloid dose used in this study represents a level for minimal induction of the ergot toxicity response.  (+info)

Physiological study of ergot: induction of alkaloid synthesis by tryptophan at the enzymatic level. (7/48)

The enhancement of ergot alkaloid production by tryptophan and its analogues in both normal and high-phosphate cultures is more directly related to increased dimethylallyltryptophan (DMAT) synthetase activity rather than to a lack of regulation of the tryptophan biosynthetic enzymes. Thiotryptophan [beta-(1-benzo-thien-3-yl)-alanine] is rather ineffective in the end product regulation of tryptophan biosynthesis, whereas tryptophan and 5-methyltryptophan are potent effectors. The presence of increased levels of DMAT synthetase in ergot cultures supplemented with tryptophan or thiotryptophan, and to a lesser extent with 5-methyltryptophan, suggests that the induction effect involves de novo synthesis of the enzyme. Thiotryptophan and tryptophan but not 5-methyltryptophan can overcome the block of alkaloid synthesis by inorganic phosphate. The results with thiotryptophan indicate that the phosphate effect cannot be explained merely on the basis of a block of tryptophan synthesis.  (+info)

Mycotoxins and reproduction in domestic livestock. (8/48)

Molds are parasitic plants that are ubiquitous in livestock feedstuffs. Even though molds themselves reduce the quality of grains, their synthesis of chemical substances termed mycotoxins causes the greatest monetary loss to the animal industry. Five major mycotoxins that impair growth and reproductive efficiency in North America are aflatoxins, zearalenone, deoxynivalenol, ochratoxin, and ergot. Aflatoxins are produced by Aspergillus flavus and Aspergillus parasiticus. Consumption of grains containing aflatoxins by swine affects reproduction indirectly by reducing feed intake and growth. In swine, aflatoxins impair liver and kidney function, delay blood clotting, increase susceptibility to bruising, and interfere with cellular humoral immune systems. Ruminants are comparatively resistant to aflatoxicosis, but presence of aflatoxins in milk of dairy cows is closely monitored for human safety. Depending on environmental conditions, Fusarium roseum can produce either zearalenone or deoxynivalenol. Days 7 to 10 postmating seem to be a critical period of gestation for zearalenone to exert its detrimental actions on early embryonic development. Presence of deoxynivalenol in swine feedstuffs decreases feed intake, causes feed refusal, and induces occasional vomiting. Several species of Penicillium and Aspergillus produce ochratoxin, a mycotoxin that causes necrosis of kidney tissue. Ergot alkaloids produced by Claviceps purpurea on wheat can cause reproductive problems and are associated with lactational failure in swine. Various methods have been developed to remove mycotoxins from infected feedstuffs. Chemical analyses in laboratories as well as diagnostic kits suitable for use at the elevator or farm can be used successfully to identify which mycotoxins are present in suspect feedstuffs.  (+info)

Series/Report Number: COARC2016 Abstract: Ergot is an important disease of Kentucky bluegrass seed production in Oregon. The disease is caused by the fungal pathogen Claviceps purpurea, which infects flowers prior to fertilization resulting in the production of sclerotia rather than seed. Sclerotia are the overwintering structures of the fungus and produce airborne ascospores
Tim Evans, a veterinary toxicologist was called to ranch in Missouri recently to try to determine what might have killed 4 of their 20 cows. It turned out that the grass they were eating was infected with the mycotoxin ergot, made by Claviceps fungi. Chemically ergot is related to LSD and was linked to deadly human epidemics in the Middle Ages. Some historians believe that ergot was the cause of The Salem Witch Hunts and St. Anthonys Fire, in which people scratched until they bled, convulsed and hallucinated. The article continues by stating that ergot compounds cause arteries to constrict, causing labored breathing, elevated body temperatures and restricted blood supply to extremities.. In other news, Pharmatimes.com reports that 13% of Americans now take antidepressants. Do you see the same link that I do?. MY TAKE-if antidepressants were available during the middle ages, 100% of those suspected of being witches would have been on them. Yes, there are some antifungal properties in todays ...

Type 1 diabetes (T1D) results from autoimmune destruction of insulin-producing β cells in islets of Langerhans. Many genetic and immunological insights into autoimmune disease pathogenesis were initially uncovered in the context of T1D and facilitated by preclinical studies using the nonobese diabetic (NOD) mouse model. Recently, the study of T1D has led to the discovery of fatty acid esters of hydroxyl fatty acids (FAHFAs), which are naturally occurring hybrid peptides that modulate inflammation and diabetes pathogenesis, and a hybrid lymphocyte that expresses both B and T cell receptors. Palmitic acid esters of hydroxy stearic acids (PAHSAs) are the most extensively studied FAHFA. In this issue of the JCI, Syed et al. have shown that PAHSAs both attenuate autoimmune responses and promote β cell survival in NOD mice. Given the lack of effective T1D therapies and the paucity of known side effects of PAHSAs, this lipid may have therapeutic potential for individuals at risk for or newly ...

Secalonic acids A, B, and C, are chiral dimeric tetrahydroxanthones closely related to ergoflavin and ergochrysin A that are collectively called ergochromes and belong to a class of mycotoxins initially isolated as major ergot pigments from the fungi Claviceps purpurea that grows parasitically on rye grasses. From early times and particularly in medieval Europe the consumption of grains containing ergot has repeatedly lead to mass poisonings known as ergotism which was caused by toxic ergot alkaloids and mycotoxins such as the ergochromes, due to contamination of flour by C. purpurea. Secalonic acid D the enantiomer of secalonic acid A is a major environmental toxin, isolated from the fungus Penicillium oxalicum, and is a major microbial contaminant of freshly-harvested corn which causes toxicity through contamination of foodstuffs.

Heterologously expressed MopA and the AHP domain catalyze Mn(II) oxidation.In order to increase expression of and aid in purification of the Mn-oxidizing protein as well as to determine the domain necessary for activity, mopA and the AHP domain of mopA (Fig. 1) were cloned and heterologously expressed in E. coli Rosetta 2. The operon containing the mopA gene in Erythrobacter sp. SD21 has not been characterized, and mopA may be the only gene in its operon. Upstream of mopA, there is a two-component system response regulator that has currently not been linked to Mn oxidation. Therefore, no additional genes were expressed with mopA. The full-length mopA gene was cloned into the modified pSpeedET expression vector carrying a C-terminal His tag and a gIII N-terminal signal sequence. Several constructs with the His tag on the N or C terminus, different lengths of the His tag, and different expression vectors were tested for activity, with the most stable Mn-oxidizing activity occurring when expressed ...

Unusual comQXPA-like loci.(A) Non-canonical unusual com system is present in B. cereus VD102, B. cereus BAG4X12 1, B. cereus MSX A1 and L. fusiformis ZC1. Note
The leaves and starchy, tuberous roots of some species are used as foodstuffs (e.g. sweet potato and water spinach), and the seeds are exploited for their medicinal value as purgatives. Some species contain ergoline alkaloids that are likely responsible for the use of these species as ingredients in psychedelic drugs (e.g. ololiuhqui). The presence of ergolines in some species of this family is due to infection by fungi related to the ergot fungi of the genus Claviceps. A recent study of Convolvulaceae species, Ipomoea asarifolia, and its associated fungi showed the presence of a fungus, identified by DNA sequencing of 18s and ITS ribosomal DNA and phylogenetic analysis to be closely related to fungi in the family Clavicipitaceae, was always associated with the presence of ergoline alkaloids in the plant. The identified fungus appears to be a seed-transmitted, obligate biotroph growing epiphytically on its host.[1] This finding strongly suggests the unique presence of ergoline alkaloids in some ...

The ergoline d-lysergic acid diethylamide (LSD) is one of the most potent psychedelic drugs. 1-Acetyl-LSD (ALD-52), a derivative of LSD containing an acetyl group on the indole nitrogen, also produces psychedelic effects in humans and has about the same potency as LSD. Recently, several other 1-acyl-substitued LSD derivatives, including 1-propanoyl-LSD (1P-LSD) and 1-butanoyl-LSD (1B-LSD), have appeared as designer drugs. Although these compounds are assumed to act as prodrugs for LSD, studies have not specifically tested this prediction. The present investigation was conducted to address the gap of information about the pharmacological effects and mechanism-of-action of 1-acyl-substituted LSD derivatives. Competitive binding studies and calcium mobilization assays were performed to assess the interaction of ALD-52, 1P-LSD, and 1B-LSD with serotonin 5-HT2 receptor subtypes. A receptorome screening was performed with 1B-LSD to assess its binding to other potential targets. Head twitch response ...
Archives of General Psychiatry, 1962; 6 (203-213). .pdf version. Since the hallucinogenic properties of D-lysergic acid diethylamide (LSD-25) were accidentally discovered by Hoffman in 1943 there has been wide experimentation with the drug designed to test its properties both as a psychotomimetic and as a therapeutic agent. It has been considered by some investigators as having great value in revealing the nature of the schizophrenic state and thereby advancing the understanding that leads to progress in therapy. However, other investigators, while acknowledging the undoubted psychic effects of the drug, insist that the LSD experience cannot be equated with naturally occurring psychosis. (fn 1) It is not the first psychopharmaceutical agent to be used as an adjunct to psychotherapy; most of its predecessors were greeted with equal enthusiasm by some because of their action in unlocking the gates of repression and thus leading to disinhibition and catharsis. In fact, according to Hoch, careful ...
glycosides having antibacterial activity using Koenigs-Knorr glycosylation reaction. On the whole, 28 ricinoleic acid glycosides were developed and their antibacterial activities were analysed. Seven of them were found to show promising wide spectrum antibacterial activity against gram positive bacteria.. Among the 7 compounds, two compounds namely mannopyranosyl- and the arabinofuranosyl derivatives were found to be effective against various non-clinical/clinical, overexpressed/resistant strains of Staphylococcus aureus and other gram positive bacteria such as Bacillus subtilis and Micrococcus luteus. It was found that the presence of sugar and its structure and the methyl ester protection of the carboxylic moiety of ricinoleic acid are responsible for these compounds to be bioactive.. Now industries looking for other potential compounds with antibacterial activity could go for these ricinoleic acid glycosides.. Wish to know more about Ricinoleic Acid - see here.

Several fungi in two different families--the Clavicipitaceae and the Trichocomaceae--produce different profiles of ergot alkaloids, many of which are important in agriculture and medicine. All ergot alkaloid producers share early steps before their pathways diverge to produce different end products. EasA, an oxidoreductase of the old yellow enzyme class, has alternate activities in different fungi resulting in branching of the pathway. Enzymes beyond the branch point differ among lineages. In the Clavicipitaceae, diversity is generated by the presence or absence and activities of lysergyl peptide synthetases, which interact to make lysergic acid amides and ergopeptines. The range of ergopeptines in a fungus may be controlled by the presence of multiple peptide synthetases as well as by the specificity of individual peptide synthetase domains. In the Trichocomaceae, diversity is generated by the presence or absence of the prenyl transferase encoded by easL (also called fgaPT1). Moreover, relaxed

R. Gažák, P. Sedmera). A series of dimers of antiparkinsonic ergot alkaloids (terguride, pergolide) and of a clavine (pyroclavine) was prepared and fully spectrally characterized. The new compounds were tested for their antiparasitic and immunomodulatory activities. Some dimers were found to be active against the causative agent of malaria, , namely against its strains resistant to chinin. New compounds are free of negative effects and the toxicity threshold is 2 - 3 orders lower than the active concentration. These compound constitute new in the development of novel antimalarial drugs.. New cyclic oligomers of ergot alkaloids were synthesized. This is an entirely new class of ergot alkaloid derivatives.. ...
Prenyl transfer reactions occur ubiquitously in nature and play an important role in primary and secondary metabolism in all domains of life. Prenylated secondary metabolites including indole alkaloids usually demonstrate improved biological and pharmacological activities and thus makes them to promising candidates for drug discovery and development. Important producers of such bioactive compounds are fungi of ascomycetes and bacteria of actinomycetes. The transfer reactions of a prenyl moiety from prenyl diphosphate, primarily dimethylallyl diphosphate (DMAPP), onto indole derivatives including tryptophan are mainly catalyzed in nature by the members of the dimethylallyltryptophan synthase (DMATS) superfamily. In the last years, remarkable progress has been achieved in their biochemical, molecular biological, and structural characterization, especially for DMATS enzymes from fungi. The major challenge of this thesis is to provide a better understanding of the catalytic features of these enzymes ...

Im enamored with Pink Muhly grass, and got some seeds to try next year. I tried the Dalea purpurea and it grew but when I planted them outside they disappeared, Im not sure why. I might try them again. I got some pink pussytoes and put it in a dry sunny place, I cant say it spread much but it is still alive. I think I did put newpaper under mulch near them so maybe they couldnt spread well. I also like the short red peonies that dont flop, they look great.. ReplyDelete ...
