Quorum Sensing Signal Synthesis May Represent a Selective Advantage Independent of Its Role in Regulation of Bioluminescence in Vibrio fischeri. [PDF]
The evolution of biological signalling systems and apparently altruistic or cooperative traits in diverse organisms has required selection against the subversive tendencies of self-interested biological entities.

An Evolving Perspective on the Pseudomonas aeruginosa Orphan Quorum Sensing Regulator QscR
Many Proteobacteria govern responses to changes in cell density by using acyl-homoserine lactone (AHL) quorum-sensing (QS) signaling. Similar to the LuxI-LuxR system described in Vibrio fischeri, a minimal AHL QS circuit comprises a pair of genes, a luxI-

Disalicylic Acid Provides Effective Control of Pectobacterium brasiliense
Bis(2-carboxyphenyl) succinate (disalicylic acid; DSA) is composed of two salicylic acids connected by a succinyl linker. Here, we propose its use as a new, synthetic plant-protection agent.

Short‐term hypercaloric diet induces blunted aortic vasoconstriction and enhanced vasorelaxation via increased nitric oxide synthase 3 activity and expression in
AbstractAimTo elucidate the role of the O2‐, H2O2 or NO pathways in aortic angiotensin (Ang)II‐induced vasoconstriction in Dahl salt‐sensitive (SS) rats compared with control SS‐13BN rats on a normal or hypercaloric diet.MethodsAortic function was assessed using wire myography in 16‐week‐old rats maintained on a normal diet or a 4‐week hypercaloric ...

LuxR solos in Photorhabdus species
Bacteria communicate via small diffusible molecules to mediate group-coordinated behavior, a process designated as quorum sensing. The basic molecular quorum sensing system of Gram-negative bacteria consists of a LuxI-type autoinducer synthase producing ...

Many gram-negative bacteria employ N-acylhomoserine lactones (AHL) to regulate diverse physiological processes in concert with cell population density (quorum sensing [QS]).

LuxR solo transcriptional regulators contain both an autoinducer binding domain (ABD; N-terminal) and a DNA binding Helix-Turn-Helix domain (HTH; C-terminal), but are not associated with a cognate N-acyl homoserine lactone (AHL) synthase coding gene in ...

Harvest Stage-Dependent Variation in Essential Oil Chemotype and Agronomic Yield of Parsley (<i>Petroselinum crispum</i> (Mill.) Fuss). [PDF]
Parsley (Petroselinum crispum) was harvested at four ontogenetic stages (Pet‐1 to Pet‐4; May–September) under Mediterranean field conditions. Harvest timing significantly affected both agronomic yield and essential oil (EO) composition. Biomass yield peaked at Pet‐4 (10,076 kg da−1); EO content was highest at Pet‐2 (0.70%). GC–MS identified 55 volatile
