ABSTRACT Salinity is a major threat to global agricultural productivity of staple crops such as wheat. Although microbial‐based solutions hold promise for alleviating salinity stress, practical implementation is hindered by insufficient mechanistic characterization of bioinoculants and their interactions with plants.

Mutasynthesis and Antibiotic Activity of Mupirocin Analogues
A mutasynthetic strategy was developed to prepare pseudomonic acid analogues, and their antimicrobial activities were evaluated against five bacterial strains. Feeding studies with mutant strains of Pseudomonas fluorescens revealed that C7‐desepoxy‐PA‐B was metabolised to C7‐PA‐C with loss of the 8‐hydroxyl group, but no fatty acid chain extension ...

Syntheses of Conjugated Pyrones for the Enzymatic Assay of Lovastatin Nonaketide Synthase, an Iterative Polyketide Synthase [PDF]
Lovastatin nonaketide synthase (LovB, LNKS) is an iterative type I polyketide synthase (PKS) from Aspergillus terreus that produces dihydromonacolin L (2), the biosynthetic precursor of lovastatin (1), from acetyl CoA, malonyl CoA, and S ...

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 ...

Dissection and Engineering of Modular Polyketide Synthase Extender Unit Specificity Motifs
Motif‐level engineering of acyltransferase domains in polyketide synthases enables programable extender unit selectivity. Cooperative mutations and motif exchanges reprogram substrate preference, enabling the incorporation of non‐native extender units and expanding polyketide structural diversity, with gains in activity and product yield.

Intratumoral Microbiota in Tumor: Current Understandings and Future Perspectives
Intratumoral bacteria are emerging as active regulators of cancer evolution rather than bystanders. This review outlines how tumor‐resident microbes drive tumor initiation and growth by inducing genomic instability, epigenetic reprogramming, oncogenic signaling, and chronic inflammation, while promoting metastatic spread via invasion, angiogenesis ...
