Mechanism of Lysobacter enzymogenes resistance toward fungi induced by fungal-derived signal α-terpinene [PDF]

Applied and Environmental Microbiology
Bacterial-fungal interactions (BFI) are critical drivers of ecosystem functions, and their molecular mechanisms remain incompletely understood. Chemical signals are crucial mediators of microbial communication, but the signaling mechanisms of terpene ...

Clp is a “busy” transcription factor in the bacterial warrior, Lysobacter enzymogenes [PDF]

Computational and Structural Biotechnology Journal, 2021
Cyclic AMP receptor protein (CRP) is a well-characterized group of global transcription factors in bacteria. They are known to regulate numerous cellular processes by binding DNA and/or cAMP (a ligand called bacterial second messenger) to control target ...

LesR is a novel upstream regulator that controls downstream Clp expression to modulate antibiotic HSAF biosynthesis and cell aggregation in Lysobacter enzymogenes OH11 [PDF]

Microbial Cell Factories, 2017
Background Heat-stable antifungal factor (HSAF) is a polycyclic tetramate macrolactam secondary metabolite that exhibits broad-spectrum inhibitory activities against filamentous fungal pathogens. The native yield of this chemical is low.

Characterisation of the Antibiotic Profile of Lysobacter capsici AZ78, an Effective Biological Control Agent of Plant Pathogenic Microorganisms [PDF]

Microorganisms, 2021
Determining the mode of action of microbial biocontrol agents plays a key role in their development and registration as commercial biopesticides. The biocontrol rhizobacterium Lysobacter capsici AZ78 (AZ78) is able to inhibit a vast array of plant ...

Biosynthesis of the Polycyclic System in the Antifungal HSAF and Analogues from Lysobacter enzymogenes [PDF]

Angewandte Chemie, 2018
AbstractThe biocontrol agent Lysobacter enzymogenes produces polycyclic tetramate macrolactams (PoTeMs), including the antifungal HSAF. To elucidate the biosynthesis of the cyclic systems, we identified eleven HSAF precursors/analogues with zero, one, two, or three rings through heterologous expression of the HSAF gene cluster.

Diffusion Hammerstein Spline Adaptive Filtering Based on Orthogonal Gradient Adaptive Algorithm

IEEE Access, 2022
In this paper, we propose a class of nonlinear diffusion filtering based on Hammerstein function with the spline adaptive filter (HSAF) implemented by normalised version of orthogonal gradient adaptive (NOGA) algorithm over the distributed network ...

Identification of atypical T4SS effector proteins mediating bacterial defense

mLife, Volume 2, Issue 3, Page 295-307, September 2023., 2023
Abstract To remain competitive, proteobacteria use various contact‐dependent weapon systems to defend against microbial competitors. The bacterial‐killing type IV secretion system (T4SS) is one such powerful weapon. It commonly controls the killing/competition between species by secreting the lethal T4SS effector (T4E) proteins carrying conserved ...

Spatiotemporal variability in precipitation‐growth association of Betula nana in the Siberian lowland tundra

Journal of Ecology, Volume 111, Issue 9, Page 1882-1904, September 2023., 2023
The association between secondary growth of Betula nana and precipitation in the Siberian lowland tundra is regulated by (i) macro‐ (kilometre‐scale) and micro‐topographical (metre‐scale) gradients, (ii) colimitation between temperature and moisture and (iii) nonlinear responses to precipitation extremes.
