MetabolomicsBioinspired Rhamnolipid Protects Wheat Against Zymoseptoria tritici Through Mainly Direct Antifungal Activity and Without Major Impact on Leaf Physiology

Rhamnolipids (RLs), glycolipids biosynthesized by the Pseudomonas and Burkholderia genera, are known to display various activities against a wide range of pathogens. Most previous studies on RLs focused on their direct antimicrobial activity, while only a few reports described t...

TranscriptomicsImprinted expression of genes and small RNA is triggered by localized demethylation of the maternal genome in rice endosperm
We report that rice endosperm shows a specific hypomethylation of DNA in the maternal genome, preferring regions of high DNA accessibility. Maternally expressed imprinted genes are enriched for hypomethylation at putative promoter regions and transcriptional termini, and paternally expressed genes a...

MetabolomicsExtreme genome diversity and cryptic speciation in a harmful algal bloom forming eukaryote

Harmful algal blooms (HABs) of the toxic haptophyte Prymnesium parvum are a recurrent problem in many inland and estuarine waters around the world. Strains of P. parvum vary in the toxins they produce and in other physiological traits associated with HABs, but the genetic basis ...

GenomicsGenome-wide demethylation of Arabidopsis endosperm
Parent-of-origin-specific (imprinted) gene expression is regulated in Arabidopsis thaliana endosperm by cytosine demethylation of the maternal genome mediated by the DNA glycosylase DEMETER, but the extent of the methylation changes is not known.  Here we show that virtually the entire endosperm gen...

TranscriptomicsExtensive imprinted gene expression in Arabidopsis endosperm
Some flowering plant and vertebrate genes are expressed primarily or exclusively from either the maternal or paternal allele, a phenomenon called genomic imprinting. Flowering plant imprinted gene expression has been described primarily in endosperm, a terminal nutritive tissue consumed by the embry...

MetabolomicsAntiviral metabolite 3'-Deoxy-3',4'-didehydro-cytidine is detectable in serum and identifies acute viral infections including COVID-19

BACKGROUND: There is a critical need for rapid viral infection diagnostics to enable prompt case identification in pandemic settings and support targeted antimicrobial prescribing.

METHODS: Using untargeted high-resolution liquid chromatography coupled with...
