Transcriptional and metabolic signatures of Arabidopsis responses to chewing damage by an insect herbivore and bacterial infection and the consequences of their interaction
(Frontiers Media, 2014-09-17)
Plants use multiple interacting signaling systems to identify and respond to biotic stresses. Although it is often assumed that there is specificity in signaling responses to specific pests, this is rarely examined outside ...
Primer modification improves rapid and sensitive in vitro and field-deployable assays for detection of High plains virus variants
(American Society for Microbiology, 2014-01)
A high consequence pathogen, High plains virus (HPV) causes considerable damage to wheat if the crop is infected during early stages of development. Methods for the early, accurate, and sensitive detection of HPV in plant ...
Oral re-vaccination of Eurasian wild boar with Mycobacterium bovis BCG yields a strong protective response against challenge with a field strain
(BioMed Central, 2014-04-26)
Background: Field vaccination trials with Mycobacterium bovis BCG, an attenuated mutant of M. bovis, are ongoing in Spain, where the Eurasian wild boar (Sus scrofa) is regarded as the main driver of animal tuberculosis ...
Ultrasensitive terahertz sensing with high-Q Fano resonances in metasurfaces
(AIP Publishing, 2014-10-27)
High quality factor resonances are extremely promising for designing ultra-sensitive refractive index label-free sensors, since it allows intense interaction between electromagnetic waves and the analyte material. Metamaterial ...
Recent studies in microbial degradation of petroleum hydrocarbons in hypersaline environments
(Frontiers Media, 2014-04-23)
Many hypersaline environments are often contaminated with petroleum compounds. Among these, oil and natural gas production sites all over the world and hundreds of kilometers of coastlines in the more arid regions of Gulf ...
Landowners' perceptions of risk in grassland management: Woody plant encroachment and prescribed fire
(Resilience Alliance, 2014)
Ecologists recognize that fire and herbivory are essential to maintaining habitat quality in grassland ecosystems. Prescribed fire and grazing are typically used on public reserves to increase biodiversity, improve grassland ...
σᴺ-dependent control of acid resistance and the locus of enterocyte effacement in enterohemorrhagic Escherichia coli is activated by acetyl phosphate in a manner requiring flagellar regulator FlhDC and the σS antagonist FliZ
(Wiley, 2014-08)
In enterohemorrhagic Escherichia coli (EHEC), sigma factor N (σᴺ) regulates glutamate-dependent acid resistance (GDAR) and the locus of enterocyte effacement (LEE); discrete genetic systems that are required for transmission ...
Probing the transition from an uncoupled to a strong near-field coupled regime between bright and dark mode resonators in metasurfaces
(AIP Publishing, 2014-08-27)
The coupling of multiple plasmonic resonators that sustain bright or dark modes provide intriguing spectral signatures. However, probing the onset of coupling effects while engaging the resonators with an increasing proximity ...
