ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

Potential of endophytic Beauveria bassiana against Coraebus (Coleoptera: Buprestidae) oak borers
This study demonstrates that an endophytic, oak‐associated strain of Beauveria bassiana exhibits adaptations to Quercus plants and potential against Coraebus boring beetles, supported by distinctive biological traits. Abstract BACKGROUND Oak borers in the genus Coraebus, including the bark‐ and the wood‐boring beetles C. florentinus and C. undatus, are

Diverse Bacterial PKS Sequences Derived From Okadaic Acid-Producing Dinoflagellates
Okadaic acid (OA) and the related dinophysistoxins are isolated from dinoflagellates of the genus Prorocentrum and Dinophysis. Bacteria of the Roseobacter group have been associated with okadaic acid producing dinoflagellates and have been previously ...

Identification by Genome Mining of a Type I Polyketide Gene Cluster from Streptomyces argillaceus Involved in the Biosynthesis of Pyridine and Piperidine Alkaloids Argimycins P [PDF]
Genome mining of the mithramycin producer Streptomyces argillaceus ATCC 12956 revealed 31 gene clusters for the biosynthesis of secondary metabolites, and allowed to predict the encoded products for 11 of these clusters.

This 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 ...

Tropinone synthesis via an atypical polyketide synthase and P450-mediated cyclization
Tropinone is an intermediate in the biosynthesis of tropane alkaloids. Here, the authors discovered the enzymes AbPYKS and AbCYP82M3, a non-canonical polyketide synthase and a cytochrome P450, that work sequentially to form tropinone from N-methyl-Δ1 ...

Isolation of a polyketide synthase gene from Dothistroma pini : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Molecular Biology at Massey University, Palmerston North, New Zealand [PDF]
Dothistromin is a polyketide derived mycotoxin, produced by Dothistroma pini, which is structurally related to aflatoxins produced by Aspergillus parasiticus and Aspergillus flavus. Southern blot analysis of D.

Chemical chain termination resolves the timing of ketoreduction in a partially reducing iterative type I polyketide synthase [PDF]
Synthetic chain terminators were used to capture the biosynthetic intermediates from a partially reducing iterative type I polyketide synthase, which is integrated into a multimodular biosynthesis enzyme.

Identification of Natural Isonitriles Through Ligation to an Azomethine Imine Probe
The azomethine imine (AMI)–isonitrile (NC) ligation allowed for the chemoselective detection of natural isonitriles in bacteria and fungi. The reactivity‐based screening establishes a new stereogenic center, thereby allowing for facile distinction between chiral and achiral isonitriles. The work also unraveled a unique reactivity of isonitriles bearing

Engineered transfer of the PKS/NRPS biosynthesis pathway of albicidin: A promising approach to overproduce this potent antibiotic [PDF]
Xanthomonas albilineans, which causes leaf scald disease of sugarcane, produces a highly potent pathotoxin and antibiotic called albicidin that was shown to inhibit DNA replication in both sugarcane proplastids and Escherichia coli.
