Metagenomic Insight into the Associated Microbiome in Plasmodia of Myxomycetes.

During the trophic period of myxomycetes, the plasmodia of myxomycetes can perform crawling feeding and phagocytosis of bacteria, fungi, and organic matter. Culture-based studies have suggested that plasmodia are associated with one or several species of bacteria; however, by amplicon sequencing, it was shown that up to 31-52 bacteria species could be detected in one myxomycete, suggesting that the bacterial diversity associated with myxomycetes was likely to be underestimated. To fill this gap and characterize myxomycetes' microbiota and functional traits, the diversity and functional characteristics of microbiota associated with the plasmodia of six myxomycetes species were investigated by metagenomic sequencing.

Simple and Efficient Synthesis of -Succinimidyl-4-[F]fluorobenzoate ([F]SFB)-An Important Intermediate for the Introduction of Fluorine-18 into Complex Bioactive Compounds.

-succinimidyl-[F]fluorobenzoate ([F]SFB) is commonly prepared through a three-step procedure starting from [F]fluoride ion. A number of methods for the single-step radiosynthesis of [F]SFB have been introduced recently, including the radiofluorination of diaryliodonium salts and the Cu-mediated F-fluorination of pinacol aryl boronates and aryl tributyl stannanes, but they still have the drawbacks of lengthy product purification procedures. In the present work, two approaches for the direct labeling of [F]SFB from diaryliodonium (DAI) salt () and pinacol aryl boronate () are evaluated, with a major focus on developing a fast and simple SPE-based purification procedure.
