Abstract Soil salinity is a major limiting factor for agricultural crops, which increases their susceptibility to pathogenic attacks. This particularly relevant tomato (Solanum lycopersicum), salt-sensitive crop. Fusarium wilt, caused by Fusarium oxysporum f. sp. lycopersici, significant threat production in both greenhouse and field environments. study evaluated the tolerance, biocontrol, plant growth-promoting properties of Bacillus velezensis AF12 halotolerans AF23, isolated from soil affected underground fires selected resistance saline conditions (up 1000 mM NaCl). In vitro assays confirmed that strains produced siderophores, indole-3-acetic acid (IAA), proteases, exhibited phosphate solubilization under stress (100–200 AF23 synergistic interactions with AF12, inoculation either strain individually or combination significantly improved growth Bonny Best cultivar 200 stress, leading increased shoot root weight, enhanced chlorophyll content, higher total biomass. The biocontrol potential was plants infected F. oxysporum. Both strains, combined, biomass non-saline conditions, promoting reducing infection rates (100 Genomic analysis revealed harbored genes related salt promotion. conclusion, Bacillus demonstrated strong as bioinoculants enhancing providing protection against saline-affected soils.

The rhizospheric microorganisms of agricultural crops play a crucial role in plant growth and nutrient cycling. In this study, we isolated two Streptomyces strains, sp. LM32 LM65, from the rhizosphere Vitis vinifera L. We then conducted genomic analysis by assembling, annotating, inferring phylogenomic information whole genome sequences. strain had size 8.1 Mb GC content 72.14%, while LM65 7.3 71%. Through ANI results, as well phylogenomic, pan-, core-genome analysis, found that was closely related to species S. coelicoflavus, achromogenes subsp. achromogenes. annotated functional categories genes encoded both which revealed involved nitrogen phosphorus metabolism. This suggests these strains have potential enhance availability soil, promoting sustainability. Additionally, identified gene clusters associated with nitrate nitrite ammonification, nitrosative stress, allantoin utilization, ammonia assimilation, denitrifying reductase clusters, high-affinity phosphate transporter control PHO regulon, polyphosphate, These findings highlight ecological roles sustainable agriculture, particularly grapevine other crop systems.

Abstract Fungal infestation in maize reduces productivity by 80%, with leaf blight disease causing about 60% reduction grain yield. Numerous studies have shown the efficacy of synthetic chemicals reducing severity agro-systems, which was efficient but several negative impacts. Hence, there is an urgency to search for a more sustainable alternative similar or better efficiency. This study conceptualized select strain in vitro antagonistic activity against causative fungi and predict secondary metabolites produced through culture-dependent method whole genome sequencing approach. Maize pathogens, Bipolaris sp., Fusarium equiseti, Phoma were obtained from symptomatic leaves known cause diseases crops, antagonized Streptomyces sp. OP7. The OP7 isolated rhizosphere crop its cell-free supernatant extract showed antifungal phytopathogens tested. complete data Streptomyces revealed presence 16 biosynthetic gene clusters functional annotations implicating Streptomyces OP7’s capacity produce valuable agroactive compounds.
