Usûl al-Fiqh antara Ahl al-Hadîth dan Ahl al-Ra’y

ISLAMICA: Jurnal Studi Keislaman, 2014
If there is any notion in which Islam is seriously concerned with more than anything else, it is the notion of freedom of expression. No doubt, Islam has recognized this and has even institutionalized it in the form of what popularly known as ijtihad.

LuxR solos in Photorhabdus species

Frontiers in Cellular and Infection Microbiology, 2014
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 ...

Negative regulation of violacein biosynthesis in Chromobacterium violaceum [PDF]

, 2017
In Chromobacteium violaceum, the purple pigment violacein is under positive regulation by the N-acylhomoserine lactone CviI/R quorum sensing system and negative regulation by an uncharacterized putative repressor.

Computational Exploration of Putative LuxR Solos in Archaea and Their Functional Implications in Quorum Sensing

Frontiers in Microbiology, 2017
LuxR solos are unexplored in Archaea, despite their vital role in the bacterial regulatory network. They assist bacteria in perceiving acyl homoserine lactones (AHLs) and/or non-AHLs signaling molecules for establishing intraspecies, interspecies, and ...

The rhizosphere: a playground and battlefield for soilborne pathogens and beneficial microorganisms [PDF]

, 2009
The rhizosphere is a hot spot of microbial interactions as exudates released by plant roots are a main food source for microorganisms and a driving force of their population density and activities.

Microfluidic study of the chemotactic response of Escherichia coli to amino acids, signaling molecules and secondary metabolites [PDF]

, 2015
Quorum sensing and chemotaxis both affect bacterial behavior on the population level. Chemotaxis shapes the spatial distribution of cells, while quorum sensing realizes a cell-density dependent gene regulation.

Quorum Sensing Activity of Hafnia alvei Isolated from Packed Food

Sensors, 2014
Quorum sensing (QS) is a mechanism adopted by bacteria to regulate expression of genes according to population density. N-acylhomoserine lactones (AHLs) are a type of QS signalling molecules commonly found in Gram-negative bacteria which have been ...

Insights into additional lactone-based signaling circuits in Streptomyces: existence of acyl-homoserine lactones and LuxI/LuxR homologs in six Streptomyces species

Frontiers in Microbiology
Acyl-homoserine lactones (AHLs), mediating pivotal physiological activities through quorum sensing (QS), have conventionally been considered limited to Gram-negative bacteria.

Quorum sensing signals of the grapevine crown gall bacterium, Novosphingobium sp. Rr2-17: use of inducible expression and polymeric resin to sequester acyl-homoserine lactones [PDF]

PeerJ
Background A grapevine crown gall tumor strain, Novosphingobium sp. strain Rr2-17 was previously reported to accumulate copious amounts of diverse quorum sensing signals during growth.
