“…In particular, Anzalone et al (2021) found that 40% of the endophytic bacteria isolated from the tomato endorhizosphere in four tomato farms within the area from which our samples were taken belonged to the Enterobacteriaceae family. L. adecarboxylata has previously been shown to promote plant growth (Sarma et al, 2004;Shahzad et al, 2017) and to mitigate both abiotic (Kang et al, 2019(Kang et al, , 2021Ahmed et al, 2021) and biotic (Lee et al, 2023) stresses. AntiSMASH analysis revealed that the genome of the selected Leclercia strain contained a BGC for the production of enterobactin, a well-known siderophore with an extraordinary iron affinity (Raymond et al, 2003).…”

Despite their adverse environmental effects, modern agriculture relies heavily on agrochemicals to manage diseases and pests and enhance plant growth and productivity. Some of these functions could instead be fulfilled by endophytes from the plant microbiota, which have diverse activities beneficial for plant growth and health. We therefore used a microbiome-guided top-down approach to select ten bacterial strains from different taxa in the core microbiome of tomato plants in the production chain for evaluation as potential bioinoculants. These taxa included some that are commonly used as biofertilizers and biocontrol agents (PseudomonasandBacillus) as well as the less studied generaLeclercia, Chryseobacterium, Glutamicibacter,andPaenarthorbacter. When inoculated in the tomato rhizosphere, these strains promoted plant growth and reduced the severity of Fusarium Crown and Root Rot and Bacterial Spot infections. High-quality genomes for each strain were obtained using Oxford Nanopore long-read and Illumina short-read sequencing, enabling the dissection of their genetic makeup to identify phyto-beneficial traits. This yielded a comprehensive inventory of genes from each strain related to processes including colonization, biofertilization, phytohormones, and plant signaling. Traits directly relevant to fertilization including phosphate solubilization and acquisition of nitrogen and iron were also identified. Moreover, the strains carried several functional genes putatively involved in abiotic stress alleviation and biotic stress management, traits that indirectly foster plant health and growth. The gathered genomic information will be instrumental in planning the use of these bacteria individually or in consortia to enhance plant growth by coupling strains with different traits, effects, and mechanisms of action.

Hidden hunger is a significant social issue in numerous countries worldwide, causing the development of nutrition-related diseases among populations annually. Biofortification offers a sustainable solution as it combines methods of cross-breeding, genetic engineering, agriculture, and microbiology. The authors reviewed international studies in the field of microbial biofortification in order to assess the microbial potential to enh ance the essential element content in grain crops. The review featured relevant scientific articles published by foreign experts in Scopus, ScienceDirect, and Google Scholar in 1984–2024. The keywords included biofortification, wheat, rice, oats, growth stimulation, antagonism, and phytopathogen. The sources were processed in Zotero and VOSviewer. Nitrogen fixation and nutrient solubilization are the main mechanisms of microbial biofortification. Solubilization occurs as a synthesis of organic and inorganic acids, protons, siderophores, extracellular enzymes, and other secondary metabolites. Microorganisms can improve the expression of plant genes in terms of absorption and nutrient accumulation. They also affect root systems, facilitating the extraction of nutrients from the soil. The authors summarized laboratory and field studies on microbial biofortification of rice, wheat, and barley with iron, selenium, zinc, copper, manganese, nitrogen, phosphorus, and potassium. Biofortified growth-promoting microorganisms are a sustainable, reliable, and cost-effective approach to food security and hidden hunger issues. The review offers relevant information that can be used to develop new microbial preparations for the domestic agriculture.
