, an opportunistic foodborne pathogen, has a strong resistance to osmotic stress and desiccation stress, but the current studies cannot elucidate this resistance mechanism absolutely. A mechanosensitive channel MscM was suspected of involving to desiccation resistance mechanism of To investigate the specific molecular mechanism, the mutant strain (Δ) was constructed using the homologous recombination method, and the complementary strain was obtained by gene complementation, followed by the analysis of the difference between the wild-type (WT), mutant, and complementary strains. Compared to the wild-type bacteria (WT), the inactivation rate of the Δ strain decreased by 15.

Amid escalating challenges from global climate change and increasing environmental degradation, agricultural systems worldwide face a multitude of abiotic stresses, including drought, salinity, elevated temperatures, heavy metal pollution, and flooding. These factors critically impair crop productivity and yield. Simultaneously, biotic pressures such as pathogen invasions intensify the vulnerability of agricultural outputs.

Gram-negative bacteria possess an asymmetric outer membrane, where the outer leaflet consists of LPSs and the inner leaflet comprises phospholipids. , an opportunistic milk-borne pathogen that causes severe neonatal meningitis and bacteremia, displays diverse lipopolysaccharide (LPS) structures. As a barrier of the bacterial cell, LPSs likely influenced resistance to environment stresses; however, there are no research reports on this aspect, hindering the development of novel bactericidal strategies overcoming the pathogen's resilience.

Plasma membrane intrinsic proteins (PIPs), one sub-family of aquaporins (AQPs), are responsible for plant abiotic stress responses. However, little information is currently available about the stress responsiveness of the promoter in vegetable pea. In the present study, one novel promoter of which shared high similarity to the -type from other plants, was isolated.

Cork oak forests have been declining due to fungal pathogens such as . However, the preventive fungicides against this fungus have restricted use due to the deleterious effects on human health and the environment, prompting the need for sustainable alternatives. Here, we describe the antifungal activity of an aqueous extract of L.
