Bacillus amyloliquefaciens is a widely used plant growth-promoting rhizobacterium. To investigate its role and mechanisms in selenium (Se) biofortification in crops, a pot experiment with four treatments including no application of Se fertilizer and B. amyloliquefaciens (control), B. amyloliquefaciens application (BA), Se fertilizer application (Se), and combined B. amyloliquefaciens and Se fertilizer application (BA + Se) was conducted. The results showed that, BA + Se treatment significantly increased total biomass of tea seedling compared with control, BA and Se treatments. Additionally, compared with Se treatment, BA + Se treatment significantly increased the Se concentrations in root and leaf, and Se content in the whole tea seedling by 101.4%, 34.5%, and 149.5%, respectively; BA + Se treatment also significantly increased the soil exchangeable Se and total available Se concentrations. Compared with control, BA treatment upregulated the expression level of CsPHT1;2b; Se treatment upregulated the expression levels of CsSULTR1;1, CsSULTR1;2, CsPHT1;2a and CsPHT1;2b; BA + Se treatment upregulated the CsSULTR1;1 and CsPHT1;2a expression levels in tea seedling roots. The 16S rRNA indicated that BA and Se treatments had no effects on the diversity of rhizosphere bacterial community, but altered bacterial community composition. Soil pH was the most important environmental factor affecting rhizosphere bacterial community composition. BA + Se treatment significantly increased soil pH and the complexity of rhizosphere bacterial symbiotic network, compared with other three treatments. Furthermore, comparative analysis about rhizosphere soil properties and bacterial community composition and function between Se and BA + Se treatments, suggested that BA + Se treatment promoted soil Se availability by recruiting g_Sinomonas species and regulating the abundance of Se reductase in the rhizosphere.
Ammonia nitrogen (NH3-N) pollution poses a critical challenge to global aquaculture sustainability. Here, we report the isolation and characterization of Bacillus subtilis DM115, a novel probiotic strain that demonstrates exceptional NH3-N degradation capabilities in ornamental fish aquaculture. Under optimized conditions, DM115 achieved 98.45% NH3-N reduction within 24 h, while exhibiting broad-spectrum antimicrobial activity against major aquaculture pathogens with minimal antibiotic resistance. In vivo studies using koi (Cyprinus rubrofuscus haematopterus) revealed that DM115 not only effectively reduced NH3-N levels to 0.25 mg/L (99.37% efficiency) but also significantly enhanced fish survival (86.67%) through modulation of antioxidant enzyme activities and inflammatory response pathways. Our findings establish DM115 as a promising probiotic agent for sustainable aquaculture water quality management, offering an environmentally conscious alternative to conventional treatment methods.

I’d like to run trials on grafting European pear varieties on Bradford pear (Pyrus calleryana) and have a question.
Bradfords are extremely invasive where I’m at so I figured I’d try my luck at removing them from my local woods and using them as rootstock to grow food. Maybe in the future this could inspire people to do the same. It is known that P. calleryana is a compatible rootstock for most pear varieties, especially European pears.
Bradford’s are known to live only 15-20 years before they seemingly spontaneously explode under their own weight or little more than a gentle breeze. My question is if used as a rootstock, will the resulting union tree be limited to a 15-20 year lifespan? Is the lifespan of the Bradford a result of the tree inevitably destroying itself or is it genetic? I know other pear varieties can live well over 200 years. Thanks.
