“…The growth of a Brassica seed crop in the open field bears a high risk for the occurrence of seed infections with Xcc. Inoculum can be present on leaves of an infected Brassica plants nearby the seed production fields (Silva et al, 2017), on alternative host plants including weeds (Krauthausen et al, 2011), and in crop debris in or on soil . Transmission of the pathogen from the inoculum sources may occur via aerosols, water splashes or by insects .…”

“…In light of the above information, it is crucial to emphasize that among the great array of microorganisms present on plants, phyllosphere bacteria stand out as a prominent category. These bacteria, which number in the thousands, serve an important role in preserving ecological balance and fostering plant health [12]. As one of their key tasks, they act as biological control agents, successfully controlling numerous plant diseases such as Xoo.…”

This study aimed to explore the potential of phyllosphere bacterial isolates as biological control agents against Xanthomonas oryzae pv. oryzae (Xoo). We isolated a strain exhibiting typical morphological and biochemical characteristics of Xoo, such as a yellowish, spherical colony, Gram-negative, and starch hydrolyzing ability. This isolate was shown to cause necrotic lesions on rice leaves, corroborating its pathogenic nature. Subsequently, we isolated ten diverse phyllosphere bacteria from rice plants. These isolates were characterized based on various morphological and biochemical attributes including colony shape, margin appearance, color, growth time, and the ability to fluoresce under UV light when cultivated on King's B medium. Crucially, none of these isolates induced a hypersensitive response in tobacco leaves, an initial indicator of their potential as safe biological control agents. In an antagonistic assay against Xoo, all the phyllosphere isolates demonstrated varying levels of inhibition, suggesting their potential role in biological control. Two isolates, PGM1 and PGM4, exhibited the highest antagonistic effects against Xoo. These findings provide preliminary evidence for the potential use of these phyllosphere isolates in managing bacterial leaf blight in rice, warranting further research to confirm their efficacy and safety under field conditions.

“…This rich diversity has been shown to possibly be linked to different production systems (Abrahamian et al, 2019 ; Klein-Gordon et al, 2021 ) and cultivated regions (Chen et al, 2021 ). Xanthomonas species are also an important component of the plant, rhizosphere and soil microbiomes (da Silva et al, 2021 ). The ability of this species to infect novel hosts and occur in different regions of the world has led to an increased research on such topics as host-pathogen interactions, virulence and pathoadaption.…”

Editorial on the Research Topic Emergence and re-emergence of plant diseases caused by Xanthomonas speciesThe emergence and re-emergence of plant diseases has increased noticeably in recent years. This has been attributed to climate change, monoculture and trade (Willocquet et al., 2020). An example is the occurrence of Xylella fastidiosa in different regions of the world (Almeida and Nunney, 2015). It was described as a "relatively obscure pathogen" in 2002 (Hopkins and Purcell, 2002), but 10 years later it is now considered a major threat to agriculture worldwide.Xanthomonas species are members of the Lysobacteriaceae (previously known as Xanthomonaceae), a family within the class Gammaproteobacteria. They have an extremely wide host range, infecting both monocotyledonous and dicotyledonous plants. The number of first reports of novel Xanthomonas species or pathovars has increased in recent years (Bansai et al., 2022; Dia et al., 2022) as has the appearance of more aggressive strains of known species (Chen et al.). The same host has also been shown to harbor both pathogenic and non-pathogenic strains (Cesbron et al., 2015;Fernandes et al., 2021;Ramnarine et al., 2022). Furthermore, Xanthomonas species have been shown to have increased their host and geographic range (Curland et al., 2020;Sigillo et al., 2021). Horizontal gene transfer has been identified as one potential mechanism favouring host-range evolution (Chen et al., 2018).Xanthomonas species can colonize novel hosts and inhabit unique ecological niches due to their extensive genomic diversity. This rich diversity has been shown to possibly be linked to different production systems (Abrahamian et al., 2019;Klein-Gordon et al., 2021) and cultivated regions (Chen et al., 2021).
