s pathogens are distinct from other bacterial pathogensTo additional probe the specificity of intergenerational responses to tension, we also sought to ascertain if the substantial adjustments in pathogen resistance and gene expression observed in C. elegans offspring from parents exposed to the bacterial pathogen P. H-Ras Storage & Stability vranovensis had been specific to this pathogen or part of a general response to bacterial pathogens. We previously identified that the transcriptional response to P. vranovensis in F1 progeny is distinct from the response to P. aeruginosa (Burton et al., 2020). To additional probe the specificity of this intergenerational response, we initial screened wild bacterial isolates from France (Samuel et al., 2016) as well as the Uk (Supplementary file five) for all those that are possible all-natural pathogens of C. elegans and that also intergenerationally have an effect on C. elegans survival or development rate. From this analysis, we identified a brand new Pseudomonas isolate, Pseudomonas sp. 15C5, exactly where parental exposure to Pseudomonas sp. 15C5 enhanced offspring HSP70 Gene ID growth rate in response to future exposure to Pseudomonas sp. 15C5 (Figure 4A). This intergenerational impact resembled C. elegans intergenerational adaptation to P. vranovensis and we found that parental exposure to either isolate of Pseudomonas protected offspring from future exposure for the other Pseudomonas isolate (Figure 4A ). To test if Pseudomonas sp. 15 C5 was a new isolate of P. vranovensis or perhaps a distinct species of Pseudomonas, we performed both 16 S rRNA sequencing and sequenced the gene rpoD of Pseudomonas sp. 15C5. From this analysis, we discovered that Pseudomonas sp. 15C5 is not an isolate of P. vranovensis and is most similar to Pseudomonas putida 99.49 identical 16 S rRNA and 98.86 identical rpoD by BLAST (Supplementary file 6). These final results indicate that parental exposure to numerous various Pseudomonas species can safeguard offspring from future pathogen exposure. We note, nevertheless, that other pathogenic species of Pseudomonas, including P. aeruginosa, did not cross defend against P. vranovensis (Burton et al., 2020), indicating that not all pathogenic species of Pseudomonas result in the exact same intergenerational in offspring pathogen resistance. As well as these intergenerational adaptive effects, we also identified two bacterial isolates that activate pathogen esponse pathways, Serretia plymutica BUR1537 and Aeromonas sp. BIGb0469 (Samuel et al., 2016; Hellberg et al., 2015), that resulted in intergenerational deleterious effects (Figure 4C ). Parental exposure of animals to these possible bacterial pathogens did not intergenerationally defend animals against P. vranovensis (Figure 4–figure supplement 1). We conclude that parental exposure to some species of Pseudomonas can safeguard offspring from other species ofBurton et al. eLife 2021;10:e73425.
