Summary: The study found that P. polymyxa NSY50 could improve the growth of tomato seedlings and significantly reduce the incidence rate of Fusarium wilt. Transcriptomic analysis showed that defense-related genes were highly expressed in tomato seedlings pretreated with NSY50, and photosynthetic efficiency, sucrose metabolism, alkaloid biosynthesis, and terpene biosynthesis were significantly improved. These findings contribute to reducing the damage caused by Fusarium wilt and enhancing the disease tolerance of seedlings.

Summary: This study identified four plant growth-promoting fungi (PGPF) that have significant antifungal activity against tomato Fusarium wilt and can enhance the immune response of tomato plants. These fungi were able to reduce disease severity and protect infected plants, while also promoting the recovery and growth of both healthy and infected tomato plants.

Summary: The addition of biochars and nanoparticles with adsorbed bacteria alleviated damage from Fusarium infection in tomato and watermelon plants. Chitosan-coated mesoporous silica nanoparticles with adsorbed bacteria showed the greatest increase in chlorophyll content in infected plants. The overall effect on disease suppression was due to the antifungal effects of nanoparticles and biochars and the presence of plant-growth promoting bacteria.

Summary: This study found that Paenibacillus polymyxa strain NX20 has a strong inhibitory effect on the mycelial growth of Phytophthora capsici, a destructive oomycete pathogen. The main factor responsible for this antagonistic action is the lipopeptide fusaricidin. Fusaricidin impairs the plasma membrane structure and leads to cell death in P. capsici, inducing reactive oxygen species accumulation and inhibiting DNA/protein synthesis. RNA-Seq analysis showed that fusaricidin treatment can potentially affect plasma membrane integrity, transmembrane transport, energy metabolism, and signal transduction in P. capsici. Furthermore, fusaricidin exhibits good control efficacy against P. capsici on watermelon, pepper, and cherry tomato fruit.

Summary: The study investigated an antibiotic produced by Paenibacillus polymyxa 7F1. Response surface methodology was used to optimize the physicochemical parameters. The strain showed broad-spectrum activity against several plant pathogens and was identified based on 16s rRNA gene and gyrB gene sequencing. The optimal fermentation conditions for the antibiotic produced by Paenibacillus polymyxa 7F1 were determined to be a culture temperature of 38 degrees C, initial pH of 8.0, and culture time of 8 h.

Summary: This study evaluated the ability of a plant growth-promoting rhizobacterium to control tomato wilt disease caused by Fusarium oxysporum and promote plant growth. The results showed significant inhibition of fungal growth, protection of susceptible tomato cultivars, and promotion of plant growth and biomass production in both susceptible and tolerant cultivars. Further analysis revealed higher amino acid production and alterations in plant defense hormone levels, suggesting that the rhizobacterium reduces the effects of Fusarium wilt disease by modulating endogenous phytohormones and amino acid levels.
