Plant Beneficial Bacteria as Bioprotectants against Wheat and Barley Diseases.

Wheat and barley are the main cereal crops cultivated worldwide and serve as staple food for a third of the world's population. However, due to enormous biotic stresses, the annual production has significantly reduced by 30-70%. Recently, the accelerated use of beneficial bacteria in the control of wheat and barley pathogens has gained prominence.

Lipopeptide-Mediated Biocontrol: Chemotaxonomy and Biological Activity.

lipopeptides (Ps-LPs) play crucial roles in bacterial physiology, host-microbe interactions and plant disease control. Beneficial LP producers have mainly been isolated from the rhizosphere, phyllosphere and from bulk soils. Despite their wide geographic distribution and host range, emerging evidence suggests that LP-producing pseudomonads and their corresponding molecules display tight specificity and follow a phylogenetic distribution.

Cyclic Lipopeptides Iturin and Fengycin Control Rice Blast Caused by in Potting and Acid Sulfate Soils by Direct Antagonism and Induced Systemic Resistance.

Rice monoculture in acid sulfate soils (ASSs) is affected by a wide range of abiotic and biotic constraints, including rice blast caused by To progress towards a more sustainable agriculture, our research aimed to screen the biocontrol potential of indigenous spp. against blast disease by triggering induced systemic resistance (ISR) via root application and direct antagonism. Strains belonging to the and group could protect rice against blast disease by ISR.

Cyclic lipopeptide-producing Pseudomonas koreensis group strains dominate the cocoyam rhizosphere of a Pythium root rot suppressive soil contrasting with P. putida prominence in conducive soils.

Pseudomonas isolates from tropical environments have been underexplored and may form an untapped reservoir of interesting secondary metabolites. In this study, we compared Pseudomonas and cyclic lipopeptide (CLP) diversity in the rhizosphere of a cocoyam root rot disease (CRRD) suppressive soil in Boteva, Cameroon with those from four conducive soils in Cameroon and Nigeria. Compared with other soils, Boteva andosols were characterized by high silt, organic matter, nitrogen and calcium.

sp. COW3 Produces New Bananamide-Type Cyclic Lipopeptides with Antimicrobial Activity against and .

species are metabolically robust, with capacity to produce secondary metabolites including cyclic lipopeptides (CLPs). Herein we conducted a chemical analysis of a crude CLP extract from the cocoyam rhizosphere-derived biocontrol strain sp. COW3.

Cyclic Lipopeptides Suppress the Rice Blast Fungus by Induced Resistance and Direct Antagonism.

Beneficial spp. produce an array of antimicrobial secondary metabolites such as cyclic lipopeptides (CLPs). We investigated the capacity of CLP-producing strains and their crude CLP extracts to control rice blast caused by , both in a direct manner and via induced systemic resistance (ISR).

Conformation and Dynamics of the Cyclic Lipopeptide Viscosinamide at the Water-Lipid Interface.

Cyclic lipodepsipeptides or CLiPs from are secondary metabolites that mediate a wide range of biological functions for their producers, and display antimicrobial and anticancer activities. Direct interaction of CLiPs with the cellular membranes is presumed to be essential in causing these. To understand the processes involved at the molecular level, knowledge of the conformation and dynamics of CLiPs at the water-lipid interface is required to guide the interpretation of biophysical investigations in model membrane systems.

Fluorescent Pseudomonas and cyclic lipopeptide diversity in the rhizosphere of cocoyam (Xanthosoma sagittifolium).

Cocoyam (Xanthosoma sagittifolium (L.)), an important tuber crop in the tropics, is severely affected by the cocoyam root rot disease (CRRD) caused by Pythium myriotylum. The white cocoyam genotype is very susceptible while the red cocoyam has some field tolerance to CRRD.
