Summary: C. elegans must distinguish pathogenic from nutritious bacterial food sources among the many bacteria it is exposed to in its environment1. Here we show that a single exposure to purified small RNAs isolated from pathogenic Pseudomonas aeruginosa (PA14) is sufficient to induce pathogen avoidance, both in the treated animals and in four subsequent generations of progeny. The RNA interference and piRNA pathways, the germline, and the ASI neuron are required for bacterial small RNA… 

Bacterial small RNAs and host epigenetic effectors of a transgenerational memory of pathogens in C. elegans

This work uses C. elegans and its bacteria to study the transgenerational RNA dynamics of an interspecies crosstalk leading to a heritable behavior, and identifies a small RNA RsmY, involved in quorum sensing from P. aeruginosa as required for initiation of PIDF.

Interspecies RNA Interactome of Pathogen and Host in a Heritable Defensive Strategy

A broad spectrum of tools can be applied for the identification of potential sRNA and mRNA targets of the interspecies RNA interaction that can be subsequently tested experimentally.

Within-species control reveals novel immune response genes in Caenorhabditis elegans

It is demonstrated that many aspects of worm behavior, health-span, longevity, food attraction, brood size, lifespan, and pathogen avoidance and survival are not affected in z11, and it is shown that the use of z11 as a control for transcriptomics analysis can increase the discovery power.

Horizontal and vertical transmission of transgenerational memories via the Cer1 transposon

It is found that C. elegans protects itself from pathogens by “reading” bacterial small RNAs and using this information to both induce avoidance and transmit memories for several generations, and these memories can be transferred to naïve animals via Cer1 retrotransposon-encoded capsids.

Small RNAs couple embryonic developmental programs to gut microbes

It is shown that Caenorhabditis elegans undergoes additional embryonic cell divisions in response to maternal gut microbes such as one producing the biopolymer γ-poly-DL-glutamic acid.

C. elegans: out on an evolutionary limb

The extensive molecular plasticity that is characteristic of immune defences in C. elegans is illustrated and some remarkable instances of lineage-specific innovation in innate immune mechanisms are highlighted.

Small RNA pathways in the nematode Ascaris in the absence of piRNAs

The authors compare Argonaute proteins and small RNAs from C. elegans and Ascaris, expanding the understanding of the conservation, divergence, and flexibility of Argonautes and small RNA pathways in nematodes.

bZIP transcription factor zip-2 mediates an early response to Pseudomonas aeruginosa infection in Caenorhabditis elegans

Zip-2, a bZIP transcription factor that is required for inducing irg-1, as well as several other genes, and is important for defense against infection by P. aeruginosa, are identified, indicating that zip-2 is part of a specialized pathogen response pathway that is induced by virulent strains of P.aerugin Rosa and provides defense against this pathogen.

Escherichia coli noncoding RNAs can affect gene expression and physiology of Caenorhabditis elegans

It is demonstrated that E. coli noncoding RNAs can regulate gene expression and physiological conditions of C. elegans and indicate that nonc coding RNAs might have interspecies ecological roles.

Caenorhabditis elegans SID-2 is required for environmental RNA interference

The identification and characterization of SID-2, an intestinal luminal transmembrane protein required for environmental RNAi in C. elegans is reported, which when expressed in theEnvironmental RNAi defective species Caenorhabditis briggsae, confers environmentalRNAi.

An in-depth transcriptional profiling of P. aeruginosa when grown at host-related temperatures identifies regulatory features of this organism whose products play a role in environmental adaption during infection and provides a reference transcriptional landscape for this pathogen.
