UV mutagenesis‐enhanced Streptomyces nogalater produces a novel streptothricin‐like compound with strong activity against cabbage soft rot

open access: yesPest Management Science, EarlyView.
UV mutagenesis of Streptomyces sp. KRA0514‐6 yielded HL‐3, a novel streptothricin‐like compound (C17H29N7O8) with N‐methylglycine replacing β‐lysine, achieving 100% cabbage soft rot control at >1 ppm concentration. Abstract BACKGROUND A total of 1000 soil‐derived actinomycetes were isolated and screened for antibacterial activity against Pectobacterium

An indole dimer antifungal metabolite from a rice seed endophyte inhibits ergosterol biosynthesis in fungal pathogens

open access: yesApplied and Environmental Microbiology
The increasing prevalence of fungal phytopathogens and the widespread emergence of fungicide resistance necessitate the development of alternative antifungal strategies with reduced environmental impact. Here, we report the isolation and characterization

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Fungal infection affects sexual signalling and mate choice in the sugarcane borer

open access: yesEcological Entomology, EarlyView.
Fungus‐infected Diatraea saccharalis females exhibit enhanced attractiveness to males in wind tunnel assays. Fungal infection alters the pheromone profile of females, increasing the relative abundance of Z9‐16: Ald, a minor but behaviourally active component of the species' sex pheromone blend.

Structural and thermodynamic analyses of a novel β‐1,2‐glucan binding mode in the ABC transporter solute‐binding protein Chy400_4166 from Chloroflexus aurantiacus

open access: yesThe FEBS Journal, EarlyView.
Cyclic β‐1,2‐glucan (CβG)‐associated solute‐binding protein of type I ABC transporter was originally identified in Chloroflexus aurantiacus, a phototrophic bacterium. Crystal structures in complex with CβGs revealed unique binding modes that are fundamentally distinct from that of the short β‐1,2‐glucooligosaccharides‐binding protein.

Insights into tandem dioxygenases—copper radical oxidases in fungal Phytopathogens of the Colletotrichum acutatum species complex

open access: yesThe FEBS Journal, EarlyView.
In Colletotrichum acutatum species complex, conserved ring‐cleavage dioxygenases located adjacent to AA5_2 enzymes were investigated as potential redox partners. Biochemical analyses identified the dioxygenases as intradiol‐cleaving enzymes preferentially oxidizing methyl‐substituted catechols, while AA5_2 enzymes displayed weak alcohol oxidase ...

Phytopathogen emergence in the genomics era

open access: yesTrends in Plant Science, 2015
Phytopathogens are a global threat to plant agriculture and biodiversity. The genomics era has lead to an exponential rise in comparative gene and genome studies of both economically significant and insignificant microorganisms. In this review we highlight some recent comparisons and discuss how they identify shared genes or genomic regions associated ...
