Summary: Xanthomonas gardneri is the common causal agent of bacterial spot affecting field tomatoes in Ontario, Canada. The spread during transportation and irrigation can influence pathogen movement. Contaminated transplanters may not be the main factor contributing to X. gardneri transmission under field conditions. Symptomatic seedlings in the transplanter can lead to transmission of X. gardneri. Management practices for bacterial spot in field tomatoes should consider irrigation practices and other factors influencing pathogen spread.

Summary: Imaging technology can provide insights into biological processes governing plant-pathogen interactions. The use of bioluminescent Xanthomonas hortorum pv. gardneri allows for quantification of infection processes in plants. Positive correlations were observed between bioluminescence signals emitted by Xg(b) and bacterial populations, as well as between X. hortorum pv. gardneri-inoculated tomato lines evaluated by bioluminescence imaging and tomatoes rated in the field using the Horsfall-Barrat Scale.

Summary: The study found that under irradiation conditions, all concentrations of dye solutions effectively inhibited bacterial growth, significantly reducing the amount of bacteria detected in seeds treated with different dyes. The dyes did not interfere with seed germination and seedling emergence, thus presenting a new seed treatment technique for controlling Xanthomonas gardneri in tomato seeds.

Summary: This study investigated the relationship between foliar and fruit resistance to bacterial spot disease in tomato. The results showed a weak relationship between foliar and fruit resistance, highlighting the need for further research to understand the mechanisms of fruit infection. In the meantime, scientists should be aware of the limitations of assessing only foliar damage.

Summary: The study found that the plant defense elicitor FytoSol can effectively prevent early blight, while 2,6-dichloroisonicotinic acid (INA) does not provide protection. FytoSol upregulated the gene expression of PR3 and downregulated the SA-related defense pathway, playing an important role in the control of early blight.

Summary: Plants can recognize pathogen-derived molecules and trigger systemic acquired resistance. This research evaluated the ability of crude lipopolysaccharide (LPS) from incompatible Xanthomonas strains to control tomato bacterial spot. The results showed that using crude LPS from host-incompatible strains can be a valuable asset to control the disease.

Summary: Flavonoids in plants have been shown to have pleiotropic effects in defense against abiotic and biotic stresses. This study investigated whether seed priming with rutin, a type of flavonoid, can enhance tomato resistance against the whitefly. The results showed that rutin seed treatment reduced the developmental rate and feeding efficiency of the whitefly, and was associated with increased flavonoid accumulation and expression of defense genes. These findings suggest that seed treatment with rutin can prime tomato resistance against the whitefly without affecting shoot growth.

Summary: Tomato, one of the most important vegetable crops worldwide, is affected by various pathogens that reduce yield and affect product quality. Studying the tomato-pathogen system can help us better understand the molecular mechanisms of disease resistance and improve crop yield and product quality. In this review, we provide an overview of recent studies on tomato transcription factors (TFs) involved in defense responses to pathogens, focusing on TF families that are abundant, important, and well-characterized.

Summary: This review provides the latest information on the defense responses of agricultural crops against Xanthomonas infection. Xanthomonas is a major bacterial genus that severely affects the productivity of economically important crops worldwide and is usually controlled using large quantities of copper-based chemicals, which have adverse environmental impacts. Advances in genomics and transcriptomics have allowed us to better understand the molecular interactions between crops and Xanthomonas. Understanding how crops respond to these infections is crucial for developing approaches to improve crop breeding and reduce productivity losses.

Summary: The study found that plants treated with INA and DPMP reduced the lesion lengths caused by bacterial canker disease and activated different molecular defense mechanisms. While both are linked to the Salicylic acid defense pathway, INA induced gene expressions of PR-5, WRKY33b, PAL, and WRKY70, while DPMP induced PR-1 and WRKY70.

Summary: Bacterial spot disease on peppers is caused by Xanthomonas species and leads to yield and quality loss. Greenhouse- and field-grown peppers are both susceptible to bacterial blight caused by xanthomonads. Developing pepper varieties resistant to Xanthomonas species is crucial for sustainable production. In this study, four wild pepper accessions of C. baccatum showed resistance to X. hortorum pv. gardneri strains, which can be used for resistance gene pyramidation in pepper.

Summary: The Bcl-2-associated athanogene (BAG) proteins play diverse functions in plant growth, stress response, and development. The SlBAG gene family in tomato was studied and 10 members were identified. SlBAG genes showed organ-specific expression patterns and were differentially expressed under multiple abiotic stresses. Heterologous overexpression of SlBAG9 increased the sensitivity of Arabidopsis to drought, salt, and ABA, resulting in the downregulation of stress-related genes and severe oxidative stress.

Summary: Bacterial spot caused by Xanthomonas spp. can lead to significant losses for tomato crops. Simonkolleite nanoparticles (SK-NPs) have shown potential for plant disease control. This study evaluated the inhibitory effects of SK-NPs (ZnOCl, ZnOCl:Ag, and ZnOCl:Cu at different concentrations) on X. hortorum pv. gardneri in vitro. The SK-NPs reduced bacterial growth, with a 5-hour exposure time being necessary for effective inhibition. Moreover, SK-NPs decreased bacterial presence on seeds without affecting germination. In plant applications, ZnOCl:Ag and ZnOCl:Cu effectively reduced disease severity. The use of SK-NPs ZnOCl:Ag and ZnOCl:Cu shows promise for managing tomato bacterial spot.

Summary: The study demonstrated that silicon supplementation in sorghum plants enhanced resistance to anthracnose disease by activating multiple processes involving hormone signaling pathways, particularly in auxin metabolism and homeostasis, hydrogen peroxide generation, and plant cell wall strengthening. Enhanced expressions of specific genes were observed in silicon-supplemented plants during the infection process of Colletotrichum sublineolum, leading to reduced fungal colonization and smaller foliar lesions when plant defense mechanisms were activated.
