A behavioral perspective on the biophysics of the light-dependent magnetic compass: a link between directional and spatial perception?
(Company of Biologists Ltd., 2010-10)In terrestrial organisms, sensitivity to the Earth's magnetic field is mediated by at least two different magnetoreception mechanisms, one involving biogenic ferromagnetic crystals (magnetite/maghemite) and the second ... -
A simple model of circadian rhythms based on dimerization and proteolysis of PER and TIM
(CELL PRESS, 1999-11)Many organisms display rhythms of physiology and behavior that are entrained to the 24-h cycle of light and darkness prevailing on Earth. Under constant conditions of illumination and temperature, these internal biological ... -
Absence of Mycobacterium intracellulare and Presence of Mycobacterium chimaera in Household Water and Biofilm Samples of Patients in the United States with Mycobacterium avium Complex Respiratory Disease
(American Society for Microbiology, 2013-03-27)Recent studies have shown that respiratory isolates from pulmonary disease patients and household water/biofilm isolates of Mycobacterium avium could be matched by DNA fingerprinting. To determine if this is true for ... -
Abundance and Size Distribution of Particulate Matter Fractions Near a Caribbean Bank Barrier Reef
(Inter-Research, 1979)Recent research indicates that corals have the ability to occupy several trophic levels and that particulate matter (PM) appears to play a major role in meeting their daily energy requirements. A study was undertaken to ... -
Accurate human microsatellite genotypes from high-throughput resequencing data using informed error profiles
(2013-01)Repetitive sequences are biologically and clinically important because they can influence traits and disease, but repeats are challenging to analyse using short-read sequencing technology. We present a tool for genotyping ... -
Actin Filament Attachments for Sustained Motility In Vitro Are Maintained by Filament Bundling
(PLOS, 2012-02-16)We reconstructed cellular motility in vitro from individual proteins to investigate how actin filaments are organized at the leading edge. Using total internal reflection fluorescence microscopy of actin filaments, we ... -
Acyl-Homoserine Lactone Recognition and Response Hindering the Quorum-Sensing Regulator EsaR
(Public Library of Science, 2014-09-19)During quorum sensing in the plant pathogen Pantoea stewartii subsp. stewartii, EsaI, an acyl-homoserine lactone (AHL) synthase, and the transcription factor EsaR coordinately control capsular polysaccharide production. ... -
Adapting to Symptoms of Global Warming Rather Than Addressing the Cause
(Virginia Tech, 2006)In recent years, global warming has been ignored and scientists producing evidence supporting this hypothesis have been denigrated and even investigated. However, as irrefutable evidence showing that global warming was a ... -
Adaptive radiation along a deeply conserved genetic line of least resistance in Anolis lizards
(Wiley, 2018)On microevolutionary timescales, adaptive evolution depends upon both natural selection and the underlying genetic architecture of traits under selection, which may constrain evolutionary outcomes. Whether such genetic ... -
An aeroponic culture system for the study of root herbivory on Arabidopsis thaliana
(Biomed Central Ltd, 2011-03-10)Background Plant defense against herbivory has been studied primarily in aerial tissues. However, complex defense mechanisms have evolved in all parts of the plant to combat herbivore attack and these mechanisms are likely ... -
Algal periphyton growth on nutrient-diffusing substrates: an in situ bioassay
(Ecological Society of America, 1985)Differences in nutrient limitation for dominant species within an algal periphyton community were determined using additions of N and P supplied by nutrient-diffusing artificial substrates. Sealed clay flowerpots were ... -
The Alternaria alternata Mycotoxin Alternariol Suppresses Lipopolysaccharide-Induced Inflammation
(MDPI, 2017-07-20)The Alternaria mycotoxins alternariol (AOH) and alternariol monomethyl ether (AME) have been shown to possess genotoxic and cytotoxic properties. In this study, the ability of AOH and AME to modulate innate immunity ... -
The Alternaria genomes database: a comprehensive resource for a fungal genus comprised of saprophytes, plant pathogens, and allergenic species
(2015-03-25)Background Alternaria is considered one of the most common saprophytic fungal genera on the planet. It is comprised of many species that exhibit a necrotrophic phytopathogenic lifestyle. Several species are clinically ... -
Alternative translation initiation codons for the plastid maturase MatK: unraveling the pseudogene misconception in the Orchidaceae
(2015-09-29)Background The plastid maturase MatK has been implicated as a possible model for the evolutionary “missing link” between prokaryotic and eukaryotic splicing machinery. This evolutionary implication has sparked investigations ...
