Plant pathogens, therefore, must remain competitive within the microbiome to establish themselves within their host niche. <i>Magnaporthe oryzae</i>, the blast disease-causing ascomycete fungus, can infect economically important hosts including rice, barley, and wheat. We sought to identify barley-associated bacteria able to antagonize <i>M</i>. <i>oryzae</i> and to characterize the fungal transcriptional responses following confrontation to reveal antimicrobial self-defense mechanisms. From a library of 25 barley-associated bacteria, two strains were identified as moderate and strong antagonists. Through RNA-seq, we demonstrate large-scale transcriptional changes in <i>M</i>. <i>oryzae</i> during their confrontation. Common responses to both strains included an overrepresentation of genes encoding drug efflux transporters, hydrolases, signaling components, DNA repair, and oxidative stress responses. This indicates that <i>M. oryzae</i> prioritizes stress adaptation and detoxification. We did not observe a significant increase in secreted proteins of <i>M</i>. <i>oryzae</i> as part of the common response. However, significant strain-specific changes were observed, indicating that, independent of host plant, specific microbial antagonists are perceived by <i>M</i>. <i>oryzae</i>, leading to altered secretome profiles. Understanding these adaptive strategies provides insight into antimicrobial resistance mechanisms with respective parallels to drug- and fungicide-resistance mechanisms in the medical and agricultural context.

Major challenges impeding this strategy are the lack of understanding of which native members of the microbiome benefit the host and the molecular signaling events underlying these benefits. In this study, we isolated a strain of <i>Roseateles chitinivorans</i>, RcP500, corresponding to the most abundant bacterial taxon in the switchgrass root microbiome. Inoculation of roots with RcP500 promoted growth and induced systemic resistance (ISR) to Bipolaris leaf spot of switchgrass and closely related <i>Panicum hallii</i>. <i>R</i>. <i>chitinivorans</i> is also highly abundant in the rhizosphere and root microbiomes of maize and rice and enhanced the growth of these two plant species. Furthermore, RcP500 elicited ISR in maize against anthracnose leaf blight and southern corn leaf blight. Bioassays and root metabolite profiling in maize wild-type and jasmonic acid (JA)-deficient <i>opr7opr8</i> mutant plants revealed the requirement of JA-dependent processes in RcP500-elicited synthesis of the JA precursor, 12-OPDA (<i>cis</i>-(+)-12-oxo-phytodienoic acid), and an α-ketol, 9,10-KODA (9-hydroxy-10-oxo-12(<i>Z</i>)-octadecadienoic acid), two oxylipins previously implicated in ISR signaling. Xylem sap transfusion of RcP500-colonized plants to naïve receiver plants corroborated the role of JA in promoting these signaling intermediates. Whereas root JA synthesis was downregulated upon RcP500 colonization, gibberellic acid was induced, suggesting a potential mechanism behind the simultaneous growth promotion and ISR triggered by this bacterium. Overall, this study identified a novel rhizobacterium with a broad host range that promotes growth and systemic resistance across multiple plant species in a JA-dependent, ketol-driven manner.

However, the specific mechanism by which AR156 induces systemic resistance against <i>Ralstonia solanacearum</i> in tomatoes remains unclear. In this study, we focused on WRKY group I transcription factors and identified WRKY4, which is downregulated by AR156 induction. Further analysis confirmed that WRKY4 functions as a negative regulator in AR156-ISR against tomato bacterial wilt. Experimental results demonstrated that WRKY4 is localized in the nucleus and exhibits transcriptional regulatory activity. Subsequent screening revealed that WRKY4 directly targets the promoter region of the SSL3 (Strictosidine Synthase-Like) gene, which encodes a key synthase for metabolic precursors, and consequently suppresses its expression. Finally, we confirmed that WRKY4 negatively regulates SSL3 expression, contributing to AR156-ISR against tomato bacterial wilt as a key negative regulator.

Laurel wilt, caused by the recently introduced fungus <i>Harringtonia lauricola</i>, is one such lethal disease threatening both native ecosystems and avocado production. Previous transcriptomic analyses determined that a massive upregulation of pathogen genes involved in the uptake and metabolism of sulfur compounds occurs during host colonization. The creation of a loss-of-function mutant for pathogen-encoded HlCys3, a bZIP transcriptional regulator of alternative sulfur utilization, abolished colonization and disease. This phenotype was complemented genetically and chemically by reintroduction of the wild-type <i>Hlcys3</i> gene in the mutant and by exogenously supplying methionine during mutant infection, respectively. These findings establish pathogen sulfur metabolism as a basic compatibility factor for this disease. The role of basic compatibility was further explored by establishing the temporal-spatial and morphological dynamics of tree host colonization by <i>H. lauricola</i> in comparison with the nonpathogenic species <i>H. aguacate</i>. The nonpathogen was able to colonize Lauraceae hosts at and adjacent to the inoculation zone, similarly to the pathogen, but was unable to systemically colonize trees. Differences in these colonization patterns were not associated with the timing or magnitude of tylosis development at the infection point. These findings indicate that basic compatibility for niche occupation must be coupled with specific compatibility factors for systemic colonization and symptom development. Determining the universality of these findings in other vascular tree wilting diseases may suggest strategies for mitigating tree mortality in ecosystems and agriculture.
