Increasing atmospheric CO levels have a variety of effects that can influence plant responses to microbial pathogens. However, these responses are varied, and it is challenging to predict how elevated CO (eCO) will affect a particular plant-pathogen interaction. We investigated how eCO may influence disease development and responses to diverse pathogens in the major oilseed crop, soybean.

Insertion sequences (IS) represent mobile genetic elements that have been shown to be associated with bacterial evolution and adaptation due to their effects on genome plasticity. In , the causative agent of whooping cough, the numerous IS elements induce genomic rearrangements and contribute to the diversity of the global population. Previously, we have shown that the majority of IS-specific endogenous promoters induce the synthesis of alternative transcripts and thereby affect the transcriptional landscape of .

Identifying the signatures of intestinal dysbiosis caused by common stresses is fundamental to establishing efficient health monitoring strategies for sea cucumber. This study investigated the impact of six common stress experienced frequently in aquaculture on the growth performance, intestinal homeostasis and microbiota of sea cucumber, including thermal (23°C), hypoosmotic (22‰ salinity), ammonium (0.5 mg/L NH -N), and nitrite (0.

The mucosal immune system, as the most extensive peripheral immune network, serves as the frontline defense against a myriad of microbial and dietary antigens. It is crucial in preventing pathogen invasion and establishing immune tolerance. A comprehensive understanding of mucosal immunity is essential for developing treatments that can effectively target diseases at their entry points, thereby minimizing the overall impact on the body.

Orally administered immunomodulatory lactobacilli can stimulate respiratory immunity and enhance the resistance to primary infections with bacterial and viral pathogens. However, the potential beneficial effects of immunomodulatory lactobacilli against respiratory superinfection have not been evaluated. In this work, we showed that the feeding of infant mice with CRL1505 or MPL16 strains can reduce susceptibility to the secondary pneumococcal infection produced after the activation of TLR3 in the respiratory tract or after infection with RVS.
