Molecular Plant Pathology, Volume 27, Issue 4, April 2026.This study revealed that the transcriptional regulator EmrR in Dickeya oryzae modulates virulence by regulating hrpL expression and c‐di‐GMP levels. It affects motility, biofilm formation, cellulase production and pathogenicity. EMSA and footprinting confirmed EmrR binds directly to the promoter of its target operon.

Methionine synthesis in Neurospora. The isolation of cystathionine [PDF]
, 1947 Among artificially produced biochemical mutants of Neurospora, those which have lost the ability to synthesize methionine form the largest class. At the present writing 87 occurrences of the methionineless character have been observed in this laboratory ...

mBio, 2017 Many proteobacteria utilize acyl-homoserine lactone quorum-sensing signals. At low population densities, cells produce a basal level of signal, and when sufficient signal has accumulated in the surrounding environment, it binds to its receptor, and ...

Molecular Mechanisms of Algicidal Bacteria in Controlling Harmful Algal Blooms: Advances in Bacteria‐Algae Interactions [PDF]
Environ Microbiol RepThis review elucidates the molecular mechanisms of algicidal bacteria, highlighting critical behaviours like chemotaxis, quorum sensing and extracellular vesicle release. It details how these actions disrupt algal cellular integrity, photosynthesis and calcium homeostasis, providing a theoretical foundation for controlling harmful algal blooms ...

[92] Homoserine dehydrogenase (Rhodospirillum rubrum) [PDF]
, 1970 Publisher Summary This chapter describes the assay, purification, and properties of homoserine dehydrogenase. Enzyme activity is measured spectrophotometrically by following the absorbance changes at 340 m μ due to the appearance or disappearance of the reduced pyridine nucleotide.

Global and Phylogenetic Distribution of Quorum Sensing Signals, Acyl Homoserine Lactones, in the Family of Vibrionaceae [PDF]
, 2014 Bacterial quorum sensing (QS) and the corresponding signals, acyl homoserine lactones (AHLs), were first described for a luminescent Vibrio species. Since then, detailed knowledge has been gained on the functional level of QS; however, the abundance of ...

One can’t stand on its own: Are non-luminescence traits necessary for V. fischeri colonization of E. scolopes? [PDF]
, 2012 Vibrio fischeri and Euprymna scolopes squid establish mutualistic symbiosis and select for each other in the natural environment. V. fischeri provides bioluminescent camouflage for E. scolopes while E. scolopes provides nutrients for V. fischeri.

Molecular Plant-Microbe Interactions, 2012 Many gram-negative bacteria use N-acyl-homoserine lactones (AHL) as quorum-sensing signals to coordinate their collective behaviors. Accumulating evidence indicates that plants can respond to AHL. However, little is known about the molecular mechanism of

Changes in the genetic requirements for microbial interactions with increasing community complexity. [PDF]
, 2018 Microbial community structure and function rely on complex interactions whose underlying molecular mechanisms are poorly understood. To investigate these interactions in a simple microbiome, we introduced E. coli into an experimental community based on a
