Bacterial signals N-acyl homoserine lactones induce the changes of morphology and ethanol tolerance in Saccharomyces cerevisiae

The bacterial quorum sensing signals N-acyl homoserine lactone (AHL) signals are able to regulate a diverse array of physiological activities, such as symbiosis, virulence and biofilm formation, depending on population density. Recently, it has been discovered that the bacterial quorum sensing (QS) signal molecules can induce extensive response of higher eukaryotes including plants and mammalian cells. However, little is known about the response of fungi reacting to these bacterial signals. Here we showed that Saccharomyces cerevisiae, as an ancient eukaryote and widely used for alcoholic beverage and bioethanol production, exposed to short-chain 3-OC6-HSL and long-chain C12-HSL appeared obvious changes in morphology and ethanol tolerance. AHLs could increase the frequency of cells with bipolar and multipolar buds, and these changes did not present distinct differences when induced by different types (3-OC6-HSL and C12-HSL) and varied concentrations (200?nM and 2?muM) of AHLs. Further investigation by flow cytometer displayed that the cells untreated by AHLs reduced cell size (decreased FSC) and enhanced intracellular density (increased in SSC), compared with the AHLs-induced cells after incubation 6?h. In addition, the long-chain C12-HSL could slightly increase the ethanol tolerance of S. cerevisiae while the short-chain HSL obviously decreased it. Our study would be valuable to further research on the interaction between prokaryotic and eukaryotic microbes, and be reference for industrial production of bioethanol.

Aromatic amino acid aminotransferases in plants

Aromatic amino acid aminotransferases (AAA-ATs) catalyze the reversible transamination reactions of proteinogenic and non-proteinogenic aromatic amino acids to corresponding keto acids and vice versa. The products of plant AAA-ATs serve as key precursors of many primary and secondary metabolites that are crucial for both plant and human metabolism and physiology. In most microbes, l-tyrosine (Tyr) and l-phenylalanine (Phe) aminotransferases (Tyr and Phe-ATs) catalyze the final steps of Phe and Tyr biosynthesis. On the other hand, plants use different pathways to synthesize Tyr and Phe via arogenate, in which prephenate-specific aminotransferases (PPA-ATs) catalyze the committed step in the plastids. Plant Tyr and Phe-ATs, unlike microbial counterparts, often prefer the reverse reactions and metabolize Tyr and Phe to their respective aromatic keto acids, which serve as precursors of various plant natural products (e.g. benzenoid volatiles, tocochromanols, plastoquinone, and tropane and benzylisoquinoline alkaloids). Unlike plastidic PPA-ATs, plant Tyr/Phe-ATs are localized outside of the plastids, have broad substrate specificity, and interlink Tyr and Phe metabolism. l-Tryptophan (Trp) aminotransferases (Trp-ATs) are involved in biosynthesis of the plant hormone auxin. Although significant advancement has been made on biochemical, molecular, and genetic characterizations of plant AAA-ATs, there are still many critical knowledge gaps, which are highlighted in the current review.

Natural products as mediators of disease

Covering: up to 2016 Humans are walking microbial ecosystems, each harboring a complex microbiome with the genetic potential to produce a vast array of natural products. Recent sequencing data suggest that our microbial inhabitants are critical for maintaining overall health. Shifts in microbial communities have been correlated to a number of diseases including infections, inflammation, cancer, and neurological disorders. Some of these clinically and diagnostically relevant phenotypes are a result of the presence of small molecules, yet we know remarkably little about their contributions to the health of individuals. Here, we review microbe-derived natural products as mediators of human disease.
