Physiological response of bacillus licheniformis NCIMB 8874to oligosaccharide elicitors
… of lower and higher concentrations of these elicitors to cultures of B. licheniformis did not have an elicitation effect on bacitracin A production, compared to the optimal reported elicitor concentration (100 – 300 mg L-1). HPAEC (high performance anion exchange chromatography) and TLC (thin …

Examination of potential elicitors of operant and respondent behaviors in smokers
… role of environmental stimuli that function as elicitors of physiological responses related to smoking. Basic research suggests that compensatory responses may play a role in drug tolerance and relapse. In one preliminary study assessing the role of compensatory responses to smoking stimuli …

Picture this: Smoking cues as conditional elicitors of compensatory responses in smokers
<p>The current study sought to extend previous research on conditional compensatory responses and illicit drugs to smoking and respondent conditioning by exposing ten adult smokers and nonsmokers to smoking and non-smoking related imagery. Pre- and post-slide show carbon monoxide (CO) levels were …

Identification and characterization of the activated defence response in the commercially important Agarophyte, Gracilaria Gracilis, following exposure to disease elicitors
… in gene expression following exposure to disease elicitors positively correlated to changes at the protein level.

People's perception of others' experienced emotions as a function of the others' status
… will experience following their encounter of the elicitors. In Study 1, participants rated the likelihood of high and low-status individuals encountering specific emotion-eliciting situations. As expected, participants considered lower status individuals as more likely to encounter the negative …

Frequency specificity of contralateral, ipsilateral and bilateral medial olivocochlear acoustic reflexes in humans
… patterns were sometimes skewed so that elicitors at frequencies above (0.5 kHz probe) or below (1 kHz probe) the probe frequency were most effective. In contrast to the wide frequency range of MOC effects from mid-level elicitors, for 1 kHz probes MOC-effect tuning curves (TCs) were …

Investigation of the effects of Elicitation and Quorum sensing on Monascus purpureus C322
… the production of these metabolites using biotic elicitors, such as oligomannuronate (OM), oligoguluronate (OG), and mannan oligosaccharides (MO) and quorum sensing molecules (farnesol, tyrosol, butyrolactone-I, linoleic acid) in M. purpureus C322. Fermentation processes were conducted in shaken …

The dynamics of molecular components that regulate aphid-plant interactions
… in the plant response to aphids. I found that elicitors present within aphids can evoke PTI/ETI defense responses. In Arabidopsis thaliana, perception of aphid elicitors requires the Leucine-Rich Repeat Receptor- Like Kinase (LRR-RLK) BAK1, which is required for multiple PTI responses via …

Manipulation of Anthocyanin Accumulation by Vaccinium Pahalae in Vitro
… and chitosan) and abiotic (FeEDDHA and CuSO4) elicitors resulted in significant enhancement of anthocyanin accumulation. Maximum anthocyanin production using the two most effective elicitors (90 muM FeEDDHA or 10 mg L -1 beta-glucan) was achieved when cultures were treated on day 3 …

Soybean aphid intra-biotype variability based on colonization of specific soybean genotypes, resistance responses of soybean genotypes to pathogen infection after the application of chemical elicitors, and resistance to charcoal rot identified in ancestral soybean germplasm
… management method is to treat plants with elicitors to induce host resistance. The objective of this research was to determine if elicitors, previously shown to elicit defense responses in other host-pathogen interactions, could induce resistance in soybean. Two soybean genotypes producing …

Temperature Induced Compatibility In The Host-pathogen Interaction Between Soybean And Phytophthora Megasperma Fsp Glycinea
… susceptible response to race 4 at 32(DEGREES)C. Elicitors from cell walls and culture filtrates of Phytophthora megasperma f. sp. glycinea reportedly stimulate glyceollin production. The effect of incubation temperatures on the production of elictors by the fungus was examined and activity in …

Dissecting the role of plant immunity in plant-aphid interactions
… aphid Myzus persicae contains several protein elicitors with varying molecular weights. These proteins are perceived by the plants Nicotiana benthamiana and Arabidopsis thaliana. In A. thaliana the perception of a 3 to 10 kDa elicitor fraction requires the leucine-rich repeat receptor-like …

Identification and characterization of an adenosine triphosphate binding cassette (ABC) transporter EcABCB1 involved in the transport of alkaloids in Eschscholzia californica
… by treatment with certain biotic and abiotic elicitors, which activates plant defense responses. Sanguinarine accumulated in the media is taken up into the cell through a potential active transport process. A large and widely distributed superfamily of proteins found in bacteria, fungi, plants …

Transformation of Gossypium hirsutum and Gossypium barbadense by Rhizobium rhizogenes: Hairy root induction and gossypol production
… media composition, temperature, and addition of elicitors and a signal transducer on culture growth rate and gossypol content were also monitored. The hairy root culture system developed by this project is a suitable model for studying gossypol biosynthesis and nematode resistance.

Elucidation of the Mechanism of Elicitation in Penicillium Chrysogenum: Systematic Approach to Study the Effect of Oligosaccharides on Production of Penicillin G
… of cytosolic calcium changes. The addition of elicitors showed a significant increase in the cytosolic Ca2+ compared to control cultures to which no elicitor was added (p < 0.001). The results found in this work aim to bring forward an understanding of the mechanism of action of elicitors in …

Molecular cloning, characterization, and expression of 3-hydroxy-3-methylglutaryl coenzyme a reductase gene from tomato
… induced in tomato cells treated with fungal elicitors and in stems, leaves, or roots stressed by wounding suggesting that the HMGz2 is a defense-related gene in tomato. Hybridization with a gene specific probe indicates that the HMG2 gene is induced specifically during defense responses and …

Risposte di resistenza a batteri fitopatogeni di importanti specie coltivate indotte da molecole segnale di diversa natura
… was compared with biofungicides and some abiotic elicitors to protect actively growing shoots of pear scions against fire blight. In both trials, IPV-BO G19 plus Na-alginate gave a high level of protection, three weeks after wound inoculation with E. amylovora. In pear leaf tissues treated with …

The role of abscisic acid in the defence response of tomato (Solanum lycopersicum) to the necrotrophic pathogens Botrytis cinerea and Erwinia chrysanthemi
… by recognition of endogenous plant cell wall elicitors. Both E. chrysanthemi and B. cinerea trigger the same type of defence responses in sitiens, which conflicts with the involvement of pathogen-specific elicitors. In addition, both pathogens produce great amounts of cell wall-degrading …

Thus, the second goal of my PhD research was aimed at determining whether GLRs are involved in the interaction between plants and pathogens. Gene expression changes of a number of candidate GLRs as well as pathogen growth was examined in …
