Bacterial LuxR solos have evolved to respond to different molecules including signals from plants

Frontiers in Plant Science, 2013
A future challenge will be understanding the extensive communication that most likely takes place in bacterial interspecies and interkingdom signaling between plants and bacteria.

Fritz Scheffer Under National Socialism: Assessing His Political Involvement

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Aims This article examines the role of soil scientist Fritz Scheffer (1899–1979) under National Socialism and offers a critical assessment of his scientific, institutional, and political positioning between 1933 and 1945. It asks how Scheffer shaped his career within the tension between disciplinary specialization, political expectations, and ...

Presence of Acylated Homoserine Lactones (AHLs) and AHL-Producing Bacteria in Meat and Potential Role of AHL in Spoilage of Meat [PDF]

Applied and Environmental Microbiology, 2004
ABSTRACTQuorum-sensing (QS) signals (N-acyl homoserine lactones [AHLs]) were extracted and detected from five commercially produced vacuum-packed meat samples. Ninety-six AHL-producing bacteria were isolated, and 92 were identified asEnterobacteriaceae. Hafnia alveiwas the most commonly identified AHL-producing bacterium.

Field Studies on the Influence of High‐Voltage Direct Transmission Underground Cables on Soils Along the SuedLink Route in Southwest Germany

Journal of Plant Nutrition and Soil Science, EarlyView.
During regular operation of the SuedLink at a load ≤75 %, the average increase in temperature in the plowing horizon is expected to be less than 1.6°C in the soils along the route in Southwest Germany. ABSTRACT Background The SuedLink was planned as a high‐voltage direct‐current underground cable route. The construction itself is a massive intervention

Non-antibiotic quorum sensing inhibitors acting against N-acyl homoserine lactone synthase as druggable target [PDF]

, 2014
YesN-acylhomoserine lactone (AHL)-based quorum sensing (QS) is important for the regulation of proteobacterial virulence determinants. Thus, the inhibition of AHL synthases offers non-antibiotics-based therapeutic potentials against QS-mediated bacterial

The power of expressed humility: Early stage investors' reaction to humble entrepreneurs

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary We examine how entrepreneur‐expressed humility affects early stage investors' willingness to fund new ventures. In pitching contexts where investors rely on relational cues and implicit prototypes of entrepreneurs, we theorize three distinct pathways through which expressed humility shapes funding decisions. First, building on

Front-propagation in bacterial inter-colony communication

, 2018
Many bacterial species exchange signaling molecules to coordinate population-wide responses. For this process known as quorum sensing the concentration of the respective molecules is crucial. Here we consider the interaction between spatially distributed

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Identification of Unanticipated and Novel N-Acyl L-Homoserine Lactones (AHLs) Using a Sensitive Non-Targeted LC-MS/MS Method. [PDF]

PLoS ONE, 2016
N-acyl L-homoserine lactones (AHLs) constitute a predominant class of quorum-sensing signaling molecules used by Gram-negative bacteria. Here, we report a sensitive and non-targeted HPLC-MS/MS method based on parallel reaction monitoring (PRM) to ...

Patient‐derived surgical samples reveal the cellular and molecular signatures of glioblastoma infiltration in distinct radiological zones

Brain Pathology, EarlyView.
Integrated histological and transcriptional profiling of the glioblastoma periphery reveals clinically relevant tumor infiltration beyond MRI‐defined boundaries. MRI‐guided biopsies from contrast‐enhancing (CE), non‐contrast‐enhancing (nCE), edema (E), and radiologically normal (N) regions demonstrate that nCE areas frequently retain neoplastic and ...
