Summary: In this study, the influence of carbohydrates and nitrogen sources on the production and selectivity of four different polyketides produced by Fusarium solani was investigated. Different combinations of carbohydrates and nitrogen sources showed varying effects on production yields and selectivity. Maximum yields did not necessarily correlate with high selectivity, which is important for easier purification steps.

Summary: The study focused on identifying differentially expressed secondary metabolites in resistant and susceptible cultivars of pea and their impact on the growth and mycotoxin biosynthesis of two different Fusarium species. It was found that certain metabolites could inhibit the pathogen's growth, while a higher level of one metabolite actually enhanced the growth of a specific Fusarium strain. Additionally, these metabolites were effective in inhibiting the biosynthesis of certain mycotoxins, regardless of the pathogen's ability to produce toxins.

Summary: Fusarium head blight (FHB) is a fungal disease that causes economic losses and reduces grain quality in cereals, such as wheat. The study analyzed 216 wheat samples infected with FHB using LC-MS/MS and found that certain mycotoxins/metabolites, including deoxynivalenol (DON) and zearalenone (ZEN), were highly prevalent. The co-occurrence of mycotoxins/metabolites was high, and their potential toxic effects should be considered. The results highlight the importance of analyzing modified and emerging mycotoxins/metabolites in future mycotoxin monitoring programs.

Summary: As we approach the post-antibiotic era, the need for new antimicrobial compounds is urgent. Microorganisms have been a rich source of antibiotics, but the rediscovery of known antibiotics and the limited accessibility of most microorganisms in the environment have prompted the exploration of natural microbial communities using novel approaches. This review discusses how sequence-based analyses have revealed the abundant potential for secondary metabolite production in soil, marine, and host-associated microbiomes, with a focus on non-ribosomal peptides and polyketides. However, the complexity of natural microbiomes and the lack of standardized methodology pose challenges in comparing different biomes. Nevertheless, even commonly sampled microbiomes hold promise for discovering novel natural products, and the development of approaches to harness the vast biosynthetic diversity of natural microbiomes for the procurement of new antibiotics is discussed.

Summary: The Caribbean region is a hotspot of biodiversity, and many organisms in this area produce polyketides through the biosynthetic pathway of PKS. These polyketides have shown biological activities against parasites, cancer, fungi, and bacteria. Researchers have summarized about 90 polyketide compounds isolated in the Caribbean from 1981 to 2020.

Summary: This study investigated the effects of Fusarium mycotoxins on wheat metabolism, revealing that plants exhibit a local defense response when exposed to toxins, potentially triggered by eavesdropping on the presence of the fungus. The research suggests that mycotoxins may initiate a plant defense mechanism and operate on multiple organs in response to fungal presence.

Summary: 6-methylsalicylic acid (6-MSA) is a small polyketide produced by fungi through horizontal gene transfer, serving as a metabolic hub for the production of various complex compounds. The most significant metabolite derived from 6-MSA is the mycotoxin patulin. Other important products include terreic acid and yanuthones. The aculin biosynthetic pathway demonstrates the most advanced modification of 6-MSA, involving non-ribosomal peptide synthase and terpene cyclase. This review summarizes the pathways originating from 6-MSA, gene clusters involved, and resulting biosynthetic pathways.

Summary: Fusarium mangiferae causes the economically significant mango malformation disease (MMD) on young mango trees and seedlings, leading to crop losses. Additionally, it produces secondary metabolites (SMs) that may contaminate the harvest. This study identifies the impact of the H3 K9-specific histone methyltransferase FmKmt1 on the expression of FmPKS8, a previously unknown polyketide synthase. The biosynthetic gene cluster (BGC) of FmPKS8 is determined, and its activity is linked to the production of fusamarins.

Summary: The plant pathogenic fungus Fusarium graminearum was found to produce a new cyclic hexapeptide named fusahexin, and a biosynthetic model for it was proposed based on the structure of fusahexin and the domain architecture of NRPS4. NRPS4 gene cluster plays a significant role during infection and oxidative and osmotic stress, making it an important pathogen in plant infection.

Summary: In the past two decades, whole-genome sequencing has greatly impacted genetic research in various kingdoms, including fungi. With the advancement of third-generation long-read DNA sequencing, highly contiguous assemblies can be obtained, but the challenge lies in extracting high molecular weight DNA, particularly from species with cell walls like fungi. Developing efficient extraction and purification methods is crucial for obtaining quality DNA for sequencing, and the study successfully demonstrated two straightforward methods for extracting high quality, high molecular weight DNA from filamentous ascomycetes, resulting in complete and contiguous assemblies for haploid fungal genomes.

Summary: Apiospora and Arthrinium have undergone significant changes in phylogenetic affiliation in the past decade. They have recently been divided into two separate clades, with Apiospora being the majority and several species changing from Arthrinium to Apiospora. The first genome annotation was available in 2020, revealing the high potential for novel secondary metabolite production in these unexplored genera. This review presents the current knowledge of 269 secondary metabolites isolated from these fungal genera, highlighting compounds with known biological or toxic effects.

Summary: This study demonstrates the influence of phoenicin and its dimer on the capacity performance of phoenicin as a negolyte in a redox flow battery. The biosynthesized fungal quinone mix of phoenicin shows the ability to store four electrons per phoenicin molecule in a redox flow battery negolyte. A detailed analysis is conducted to understand the chemical stability of phoenicin in an alkaline environment.

Summary: The production of renewable energy from solar panels and windmills has been growing rapidly in recent years. However, a major obstacle in the green transition is the need for cost-efficient energy storage to fully exploit their potential. A promising solution is the use of redox flow batteries (RFBs) with quinones as electron carriers. Currently, quinones derived from crude oil are used, which does not align with the goal of sustainable energy production from renewable sources. Recent research has shown that filamentous fungi have great potential for quinone production, and a proof-of-concept RFB using fungal-produced quinones has been developed. We discuss the challenges that need to be addressed before fungal-produced quinone RFBs can be applied in the green transition.

Summary: In this study, researchers sequenced 93 Penicillium isolates and established a species phylogeny and pangenome. They found that approximately half of the genes are shared among 98 or more isolates. They also discovered 15 lateral gene transfer events that have played a role in the evolution and adaptation of these fungi. This comprehensive characterization of the Penicillium genus surpasses single-reference genomes and captures the genetic variation.

Summary: This study investigates the life cycle and metabolome of the pathogenic fungus Fusarium graminearum, which has significant impacts on agriculture and human health. A previously unknown polyketide from the PKS2 gene cluster was identified and named fugralin A and B. Functional characterization showed that these compounds are not produced during infection and do not affect pathogenicity or visual growth. The compounds are volatile, suggesting potential functions for further investigation.
