Summary: In addition to their biological functions, polysaccharides help Lactiplantibacillus plantarum resist harsh conditions. By analyzing transcriptional regulators, a new transcriptional inhibitor called LsrR was discovered, which represses polysaccharide synthesis. Overexpression of LsrR reduced the production of EPSs and CPSs in L. plantarum. However, alkaline shock proteins and an AI-2 related quorum-sensing regulator were found to recover polysaccharide synthesis by inhibiting LsrR activity. Polysaccharides increased the survival rate of L. plantarum during lyophilization and enhanced its tolerance to low pH and bile salts.

Summary: Two candidate genes (ZmbZIP113 and ZmTSAH1) controlling low-temperature germination ability were identified through QTL-seq and integrative transcriptomic analyses. The functional verification results showed that these two candidate genes positively regulated the low-temperature germination ability of IB030. Improving maize's low-temperature germination ability is crucial for increasing yield production.

Summary: This study investigated the effects of vacuum freeze-drying (VFD) on the adhesion and survival of Lactiplantibacillus plantarum 67. The results showed that VFD significantly decreased the adhesion and survival rates of L. plantarum 67, while protective agents (PAs) exerted protective effects. Proteomics analysis revealed that differentially expressed proteins (DEPs) related to adhesins and vitality were significantly affected by VFD.

Summary: This study investigated the effects of simulated oro-gastrointestinal transit stress on the adhesion and survival of Lactobacillus plantarum S7, a potential probiotic strain. Results showed that L. plantarum S7 had a higher survival rate under certain bile salt concentrations and its adhesion ability was enhanced after exposure to specific stress conditions. Furthermore, the expression of surface proteins and pathways related to oro-gastrointestinal transit stress were regulated in L. plantarum S7. Overall, L. plantarum S7 showed strong resistance to oro-gastrointestinal stress, making it a promising probiotic candidate.

Summary: This study screened bacteriocin-producing Lactiplantibacillus plantarum strains and found that L. plantarum Q7, L. plantarum F3-2, and L. plantarum YRL45 produced bacteriocins and inhibited common intestinal pathogens. These strains exhibited probiotic potential with tolerance to the gastrointestinal environment, colonization in the gut, and various degrees of anti-inflammatory activity and tight junction function in the intestinal barrier. L. plantarum YRL45 showed significant reduction in inflammatory response, while L. plantarum F3-2 protected the intestinal barrier.

Summary: Promoting exercise regimens that aim to enhance the quality of individual exercise experiences can be challenging. This study aimed to examine the mediation role of basic psychological needs in the relationship between preference for exercise intensity and enjoyment. The results indicated positive associations between intensity-traits and enjoyment, and negative associations with needs frustration variables.

Summary: Expanding stress tolerance and adaptation potential of primary producers is crucial for the restoration and management of aquatic ecosystems. This study identified key microbes and the pathway through which they enhance turbidity tolerance of primary producers using mesocosm experiments and multivariate statistical methods. The research found a significant decrease in the biomass of primary producers with increasing turbidity. Significant differences in microbial community under various turbidity pressures were identified, and key microbes that may expand the turbidity tolerance of primary producers were further identified. The structural equation model revealed the pathway through which microbial communities help primary producers cope with turbidity pressure by enhancing the microbial loop. These findings provide new insights and a theoretical basis for resisting turbidity stress and managing and restoring aquatic ecosystems.

Summary: This study explored the salt tolerance potential of 40 local wheat cultivars against 150 mM NaCl stress. The results showed that tolerant cultivars had less reduction in biomass, K+, and P, while experiencing a greater decline in Na+ due to reduced translocation and enhanced exclusion. Salt-tolerant cultivars showed efficient scavenging of reactive oxygen species through osmotic adjustment and accelerated antioxidant enzyme activities. The findings suggest that molecular techniques can be used to identify genes related to salt exclusion, osmotic adjustment, and photosynthetic activity for molecular breeding programs.
