Summary: This study evaluated the impact of plant growth-promoting rhizobacteria (PGPR) on cucumber fruit growth and quality. The results showed that inoculation with PGPR improved various growth parameters and fruit quality, contributing to reducing costs, decreasing pollution, and achieving global food safety and security.

Summary: This study analyzed the structure of the viral satellite RNA of cucumber mosaic virus TA-Tb using the SHAPE method. Through optimization, the RNA structure was clearly elucidated, revealing the presence of non-structured, single-stranded flexible regions, particularly prominent at nucleotide positions 145 to 200. These findings provide insights into the mechanism by which satCMV TA-Tb regulates the pathogenicity and replication of its helper virus.

Summary: STV showed a synergistic effect with CMV or PepMV in co-infections, leading to increased virus titer and plant symptoms. However, an antagonistic interaction was observed between CMV and PepMV in co-infections, which was abolished by the presence of STV in triple-infections, restoring the CMV titer and plant symptoms. The expression of miRNAs and vsiRNAs varied depending on the virus combination, with differential regulation of important functions.

Summary: Two isolates TS4 and TS6 from tomato rhizosphere were found to possess different plant growth-promoting properties such as enzyme production and hydrogen sulfide (H2S) production. The colonization potential of TS4 and TS6 in the tomato rhizosphere was studied and it was observed that they had strong colonization ability. In greenhouse studies, these isolates showed positive influence on tomato growth. In summary, TS4 and TS6 are efficient plant growth-promoting rhizobacteria that can be used for high-yield cultivation in sustainable agriculture.

Summary: New technologies are being sought to enhance soil biodiversity and increase crop production while reducing the use of scarce resources to mitigate threats posed by climate change, population growth, and desertification. Challenges still remain in facilitating the delivery of plant-growth-promoting bacteria in the soil, including survival, precise delivery, competition with indigenous soil microorganisms, and soil structure.

Summary: This study examines the effects of plant-growth promoting rhizobacteria (PGPR) on host-vector-pathogen interactions. Soil-drench applications of PGPRs to tomato seedlings showed increased root length and biomass in host plants, delayed colonization of CLso pathogen transmitted by the potato psyllid, and changes in psyllid behavior and progeny sex ratio. Based on the results, PGPR may have practical use in commercial tomato production.

Summary: In this study, CRISPR-Cas9 was used to create ago2a, ago2b, or ago2ab mutants in tomato. The results showed that AGO2a plays an important role in the antiviral immune response in tomato, while AGO2b does not.

Summary: CGMMV, a seed-borne virus causing costly diseases in the vegetable trade worldwide, has limited genetic sources for resistance in cucurbits. RNA interference-based technologies, such as amiRNA and syn-tasiRNA, effectively prevented the occurrence and accumulation of CGMMV in cucumber plants, providing a basis for preventing and treating seed-based viral infections.

Summary: This study successfully enhanced the growth and yield of cherry tomato seedlings by incorporating technologies such as LED lights, plant growth promoting rhizobacteria (PGPR), and arbuscular mycorrhiza fungi (AMF). The optimal lighting conditions were LEDs at 200 mu mol/m(2)/s with a ratio of R60:B40 and 20 h/d exposure. Inoculation with specific PGPR and AMF significantly improved the health index and biomass of the tomato seedlings.

Summary: Vegetable production is an important economic activity in Ethiopia, but it is less developed compared to food grain production, requiring improvement through innovative technologies. Concerns such as soil fertility and atmospheric pollution should be addressed, and the use of plant growth promoting rhizobacteria is recommended for optimizing vegetable production.

Summary: Cucumber mosaic virus (CMV) is a widely distributed and genetically variable virus. High-throughput sequencing was used to analyze the genomes of 14 Slovak CMV variants from different plant hosts. A total of three CMV variants were found in Papaveraceae species, which were previously not well-described as CMV natural hosts. Phylogenetic analysis divided the Slovak CMV isolates into two genetically distinct groups, Ia and II. The SL50V variant with a divergent RNA2 sequence may be a reassortant variant. Satellite CMV RNA was also identified in four samples, but its role in observed symptoms could not be determined due to complex infections with different viruses in the original hosts.

Summary: The study conducted a four-year survey in Serbia from 2012 to 2015 to examine the genetic diversity of cucumber mosaic virus (CMV) isolates infecting tomato, as well as the presence and diversity of their satellite RNAs (satRNAs). The results showed that CMV-infected tomato plants exhibited severe symptoms, and analysis of CMV CP sequences revealed heterogeneity, falling into two subgroups. Additionally, the study identified the presence of heterogeneous Serbian CMV satRNAs variants, including necrogenic and non-necrogenic variants.

Summary: This study found that the effects of rhizobacteria on different tomato cultivars varied, with Tres Cantos plants producing larger fruits with more lycopene but less biomass after inoculation, while cherry plants showed no change in biomass but higher lipid peroxidation.

Summary: Autophagy plays a crucial role in plant responses to virus infection by degrading viral components and attenuating disease symptoms. Its induction is regulated by salicylic acid and suppressed by the CMV virulence factor 2b. Autophagy provides resistance against CMV by reducing viral RNA accumulation in an RNA silencing-dependent manner.
