Abstract During laboratory evolution, replicate bacterial populations often follow similar trajectories, thus their evolution is potentially predictable.

The extent to typically depend coevolving partners remains poorly understood, since coevolution studied using small-scale experiments involving few species, making it challenging extract general trends. To address this knowledge gap, we study that occurred strains each 11 species were either evolved monoculture or multiple pairwise co-cultures.

Abstract Fungal infections of fresh fruits and vegetables (FFVs) can lead to safety problems, including consumer poisoning by mycotoxins. Various strategies exist control fungal FFVs, but their effectiveness sustainability are limited. Recently, new concepts based on the microbiome pathobiome have emerged offer a more holistic perspective for advancing postharvest pathogen techniques. Understanding role in FFV is essential developing sustainable strategies. This review examines current emerging approaches pathology. It reviews what known about initiation development FFVs. As promising concept, offers insights into basic mechanisms microbial The underlying uncovered being used develop relevant global antifungal will also focus technologies developed target members FFVs improve limiting mycotoxin contamination. Specifically, this stresses related that modifying interaction between include use consortia, genomic technology manipulate host community genes, databases, deep learning, artificial intelligence identify markers. Other programming behavior using synthetic biology, sRNA technology, phages, quorum sensing, quenching Rapid adoption commercialization these recommended further overall
