Eleven new chlorinated cyclopentene derivatives, periconsins A-K, and a new diketopiperazine, periconzin, were found from Periconia sp. cultured in three different media by the one strain many compounds strategy. Additionally, the C-1 methyl hydroxylation of chlorinated cyclopentene was found for the first time in the host plant culture. The structures were identified by extensive spectroscopic analyses, electronic circular dichroism (ECD) and 13 C NMR calculations, and single-crystal X-ray diffraction. Compounds 3, 5, 7−11, 15, and 17 showed significant antifungal activities against the plant pathogens Periconia sp., Altemaria sp., and Nigrospora oryzae with MICs ≤2 μg/mL. Other compounds had antifungal activities with MICs ≤8 μg/mL. The antifungal structure−activity relationship of these metabolites indicated that the chlorine at C-5 can increase the activity, but the hydroxy group at C-1 lowered the activity.

“…In particular, we found significant increases in Burkholderia (many putative N‐fixers), as well as Rhidopila globiformis (Acetobactereaceae), a nitrogen‐fixer that may contribute to alternative N 2 ‐fixation via the vanadium‐dependent nitrogenase pathway (Imhoff et al ., 2018). By contrast, fungi exhibited increases in multiple putative pathogens after allelochemical addition (Wang et al ., 2021). These included an increase in prevalence of Gibberella , a known fungal pathogen (Bai et al ., 2021).…”

Summary Allelopathy is a common and important stressor that shapes plant communities and can alter soil microbiomes, yet little is known about the direct effects of allelochemical addition on bacterial and fungal communities or the potential for allelochemical‐selected microbiomes to mediate plant performance responses, especially in habitats naturally structured by allelopathy. Here, we present the first community‐wide investigation of microbial mediation of allelochemical effects on plant performance by testing how allelopathy affects soil microbiome structure and how these microbial changes impact germination and productivity across 13 plant species. The soil microbiome exhibited significant changes to ‘core’ bacterial and fungal taxa, bacterial composition, abundance of functionally important bacterial and fungal taxa, and predicted bacterial functional genes after the addition of the dominant allelochemical native to this habitat. Furthermore, plant performance was mediated by the allelochemical‐selected microbiome, with allelopathic inhibition of plant productivity moderately mitigated by the microbiome. Through our findings, we present a potential framework to understand the strength of plant–microbial interactions in the presence of environmental stressors, in which frequency of the ecological stress may be a key predictor of microbiome‐mediation strength.

“…As important ascomycetes, Nigrospora spp. are distributed worldwide and have a wide host range [23,24]. N. musae is a common member of this genus that can cause many plant diseases, such as fruit diseases in Musa × paradisiaca [25] and leaf diseases in Camellia sinensis [26].…”

Identification of the Pathogen Causing Leaf Spot in Zinnia elegans and Its Sensitivity to Five Fungicides

Zinnia elegans Jacq. is an important, globally cultivated ornamental plant. In August 2021, a leaf spot disease was observed in zinnia in Shibing County, Guizhou, China, with an incidence of approximately 60%. Pathogens were isolated and purified from the infected leaves by tissue isolation, and pathogen strain BRJ2 was confirmed as the pathogen causing the leaf spot. Based on morphology and ITS, TEF-1α, and TUB2 sequence analyses, the pathogen was identified as Nigrospora musae (McLennan and Hoëtte). The mycelial growth rate method was used to determine the in vitro toxicity of five fungicides to the pathogen. The results showed that 10% difenoconazole provided the strongest inhibitory effect on N. musae, with a concentration for 50% of maximal effect (EC50) of 0.0658 mg/L; 75% trifloxystrobin·tebuconazole had the second greatest effect, with an EC50 of 0.1802 mg/L. This study provides the first report that N. musae caused leaf spot disease in Z. elegans and provides important guidance for the effective prevention and control of this disease in Guizhou.
