A membrane protein of the rice pathogen Burkholderia glumae required for oxalic acid secretion and quorum sensing

Molecular Plant Pathology, Volume 24, Issue 11, Page 1400-1413, November 2023., 2023
The quorum sensing‐regulated synthesis of oxalic acid by ObcAB is needed to prevent alkaline degradation of C8‐HSL quorum sensing signalling molecules and avoid alkaline toxicity. The DedA family protein DbcA is required for oxalic acid secretion. Abstract Bacterial panicle blight is caused by Burkholderia glumae and results in damage to rice crops ...

Herbicolin A production and its modulation by quorum sensing in a Pantoea agglomerans rhizobacterium bioactive against a broad spectrum of plant‐pathogenic fungi

Microbial Biotechnology, Volume 16, Issue 8, Page 1690-1700, August 2023., 2023
Herbicolin A biosynthesis is responsible for the strong antagonistic activities of the rhizosphere bacterium Pantoea agglomerans 9Rz4 against a broad spectrum of phytopathogenic fungi. Abstract Global population growth makes it necessary to increase agricultural production yields.

Pantoea ananatis carotenoid production confers toxoflavin tolerance and is regulated by Hfq‐controlled quorum sensing

MicrobiologyOpen, Volume 10, Issue 1, February 2021., 2021
Carotenoid production confers tolerance to toxoflavin and UV radiation in Pantoea ananatis. We proposed a model of carotenoid production for the previously reported regulatory network HfqArcZ → RpoS Ͱ ClpXP and that identified here, in which Hfq‐controlled quorum signaling derepresses EanR to activate RpoS expression, thereby initiating carotenoid ...

Modulation of host biology by Pseudomonas aeruginosa quorum sensing signal molecules: messengers or traitors [PDF]

, 2015
YesBacterial cells sense their population density and respond accordingly by producing various signal molecules to the surrounding environments thereby trigger a plethora of gene expression. This regulatory pathway is termed quorum sensing (QS).

Rhodotorula Mucilaginosa, a Quorum Quenching Yeast Exhibiting Lactonase Activity Isolated from a Tropical Shoreline

Sensors, 2014
Two microbial isolates from a Malaysian shoreline were found to be capable of degrading N-acylhomoserine lactones. Both Matrix Assisted Laser Desorption Ionization-Time of Flight-Mass Spectrometry and 18S rDNA phylogenetic analyses confirmed that these ...

Heterologous production of rhamnolipids in Pseudomonas chlororaphis subsp chlororaphis ATCC 9446 based on the endogenous production of N-acyl-homoserine lactones. [PDF]

Microb Biotechnol
The heterologous production of the biosurfactant rhamnolipids in Pseudomonas chlororaphis ATCC 9446 was attained by the expression of the P. aeruginosa genes coding for the RhlA, RhlB, and RhlC enzymes involved in their synthesis. The P. aeruginosa quorum sensing transcriptional regulator RhlR coupled with acylhomoserine lactones endogenous produced by

Effects of different N-acyl-serine lactone signaling molecules on the performance of anaerobic granular sludge

RSC Advances, 2022
Exogenous addition of acyl-homoserine lactone (AHL) signaling molecules can improve or inhibit the methane production performance of anaerobic granular sludge (AnGS) by quorum sensing (QS).

Gac two-component system in Pseudomonas syringae pv. tabaci is required for virulence but not for hypersensitive reaction [PDF]

, 2008
Pseudomonas syringae pv. tabaci 6605 causes wildfire disease on host tobacco plants. To investigate the regulatory mechanism of the expression of virulence, Gac two-Component system-defective mutants, Delta gacA and Delta gacS, and a double mutant, Delta

Quorum Sensing: suatu Sistem Komunikasi Bakteri Fitopatogen, Peranannya pada Proses Infeksi, dan Peluangnya sebagai Basis Pengembangan Strategi Baru dalam Pengendalian Penyakit Tumbuhan [PDF]

, 2009
Previously, it is thought that bacterium is an autonomous unicellular organism with no capacity for collective behavior. Now the paradigm has changed since there are communication between intercell bacteria.
