Do Organic Amendments Foster Only Beneficial Bacteria in Agroecosystems?: The Case of Bacillus paranthracis TSO55

Plants, Journal Year: 2025, Volume and Issue: 14(7), P. 1019 - 1019

Published: March 25, 2025

Bacterial strain TSO55 was isolated from a commercial field of wheat (Triticum turgidum L. subsp. durum), under organic amendments, located in the Yaqui Valley, Mexico. Morphological and microscopical characterization showed off-white irregular colonies Gram-positive bacillus, respectively. The draft genome sequence this revealed genomic size 5,489,151 bp, with G + C content 35.21%, N50 value 245,934 L50 8, 85 contigs. Taxonomic affiliation that belongs to Bacillus paranthracis, reported as an emergent human pathogen. Genome annotation identified 5743 5587 coding DNA sequences (CDSs), respectively, highlighting genes associated indole production, phosphate potassium solubilization, iron acquisition. Further silico analysis indicated presence three CDSs related pathogenicity islands high pathogenic potential (77%), well multiple gene clusters antibiotic resistance. vitro evaluation plant growth promotion traits negative for production it positive but low (18%) siderophore production. biosynthetic cluster bacillibactin (siderophore) biosynthesis confirmed. Antifungal bioactivity evaluated against fungi (Alternaria alternata TF17, Bipolaris sorokiniana TPQ3, Fusarium incarnatum TF14) minimal fungal inhibition. An susceptibility assay resistance six antibiotics evaluated, up concentration 20 µg/mL. beta hemolysis result on blood agar reinforced TSO55's potential. Inoculation B. paranthracis seedlings resulted significant decrease root length (-8.4%), total height (-4.2%), dry weight (-18.6%), stem (-11.1%), (-15.2%) compared control (uninoculated) treatment. This work highlights importance analyzing microbiological safety amendments before application. Comprehensive genome-based taxonomic bioprospecting microbial species introduced soil by agricultural practices any inoculant will prevent introduction dangerous non-beneficial crops, which affect sustainability generate health risks plants humans.

Evaluating wheat response to biostimulants: a 25-year review of field-based research (2000–2024)

Frontiers in Sustainable Food Systems, Journal Year: 2025, Volume and Issue: 9

Published: March 28, 2025

Wheat, a staple crop, faces numerous challenges due to climate change and the increasing demand for sustainable practices. Biostimulants, which enhance plant growth resilience, have gained attention their potential improve wheat productivity in an environment-friendly manner. This study presents comprehensive bibliometric analysis of field-based research on wheat's response biostimulants under field conditions from 2000 2024. Analyzing 222 studies, reveals significant rise publications biostimulants, with annual rate 15.6%. Asia leads largest share (59.4%), followed by Europe (18.1%) Africa (11.6%). North America, South America Oceania fewer contributions. Additionally, institutions Pakistan, India Egypt rank as most productive this topic. Saudi Arabia stands out highest percentage international collaboration, at 91.7% between countries 100% among institutions. The findings reveal that significantly ability withstand abiotic stress, optimize nutrient uptake, overall health. Research is transitioning traditional organic methods microbial inoculants advanced biostimulant formulations, improved management, reduced environmental impact. However, gaps remain, particularly understanding combined effects multiple long-term impact soil synthesis trends lays groundwork advancing production, supporting food security agricultural resilience amidst challenges.

Growth regulation in bread wheat via novel bioinoculant formulation

BMC Plant Biology, Journal Year: 2024, Volume and Issue: 24(1)

Published: Nov. 4, 2024

Wheat (Triticum aestivum L.) is one of the most significant crops and backbone food security worldwide. However, low wheat production remains a substantial concern in global agricultural systems. It can be attributed to several factors, including adverse climatic conditions, plant disease poor soil quality. Recent efforts have explored bioinoculant applications as promising approach enhance yield, trying mitigate constraints essential for future security. This study tested talc powder, biochar, sugarcane bagasse farmyard manure carriers with two endophytic bacterial strains, Burkholderia phytofirmans PsJN Bacillus spp. MN54 was applied three varieties (Ujala-16, Zincol-16, Fathejang-16). The data recorded at seedling maturity growth stages plants. A pot experiment revealed improvements following application compared controls. Notably, combination biochar sp. exhibited pronounced effects, promoting internodal length, spike tiller number per plant, grain yield spikelets spike. Additionally, powder increased peduncle length Fathejang-16. These findings offer valuable insights into optimizing formulations improved practices, adapting climate change, contributing ensuring

Comparative Genomics of Different Lifestyle Fungi in Helotiales (Leotiomycetes) Reveals Temperature and Ecosystem Adaptations

Journal of Fungi, Journal Year: 2024, Volume and Issue: 10(12), P. 869 - 869

Published: Dec. 14, 2024

Helotiales, a diverse fungal order within Leotiomycetes (Ascomycota), comprises over 6000 species occupying varied ecological niches, from plant pathogens to saprobes and symbionts. Despite their importance, genetic adaptations temperature environmental conditions are understudied. This study investigates in infection genes substrate degradation through comparative genomics analysis of 129 Helotiales species, using the newly sequenced genomes Gyoerffyella rotula Anguillospora crassa. Key gene families such as cytochrome P450 enzymes, virulence factors, effector proteins, carbohydrate-active enzymes (CAZymes) were analyzed understand roles lifestyle adaptations, uncovering possible alternative mechanisms. Our findings reveal that fungi possess associated with nutrient acquisition, pathogenicity, symbiotic relationships strongly adapted cold environments might be impacted by global warming. On other hand, some demonstrate potential for adaptation warmer climates, suggesting increased activity response reveals adaptive mechanisms enabling thrive both warm environments. These provide valuable insights into success evolutionary resilience, which may facilitate ability transition between pathogenic, symbiotic, saprobic phases changing conditions.
