However, accumulation of these furanoterpenoids in uninfested parts of weevil-infested storage roots is poorly characterized. Here we identified ipomeamarone and its precursor, dehydroipomeamarone, in weevil-infested sweetpotato storage roots and confirmed the identities of the compounds by LC-MS, LC-MS/MS, and NMR analysis.

Bioactivated fertilizers are a promising solution to enhance digestate solid fraction's fertilizing properties with an ad hoc microbial consortium and reach yields comparable to chemical fertilization (CF), thus combining circular economy with an upgraded organic agriculture. This study designed a new granulated formulation, obtained using a vacuum drying process at the industrial level, for an improved <i>Trichoderma</i>-activated digestate's solid fraction. This granulation aimed to improve both management operations and <i>Trichoderma</i> activity. After a greenhouse experimentation, yields obtained from the activated digestate (56 ± 7 g FW plant^-1) were similar to the one obtained with CF (62 ± 9 g FW plant^-1). Additionally, the bioactivated digestate gave yield production that were 21-30% higher yield than that of digestate alone. Microbial activation further led to higher nutritional values with an increment in the lycopene content between 8.8% and 15.8%. A metagenomic analysis further highlighted the persistence of <i>Trichoderma</i> in the tomato rhizosphere and its ability to establish positive interactions with other beneficial rhizospheric microorganisms.

Regarding target PFAS extraction efficiency, EPA method 1633 also demonstrated superior performance at environmentally relevant low concentrations. At higher PFAS concentrations in plant tissues, no single method clearly dominated; however, EPA method 1633 remained consistently reliable and was never significantly outperformed by the other two methods. Overall, EPA method 1633 is recommended as the default method for routine analyses at typical environmental PFAS levels, with MTBE-NaOH method preferred when accurate isotopic correction based on EIS recovery is critical in highly contaminated plant samples. A cost comparison of these three methods further supports the preference for EPA Method 1633 and MTBE-NaOH method for plant-tissue analyses.

CuO NPs effectively inhibited the biofilm formation of <i>R. solanacearum</i> at various stages of maturity (24, 48, and 72 h) by damaging the cellular morphology and reducing the extracellular polysaccharide (EPS) and protein content of bacteria within biofilms. The motility activities of <i>R. solanacearum</i>, including swimming, swarming, and twitching, were significantly inhibited upon exposure to CuO NPs. Furthermore, we confirmed that both two-dimensional and three-dimensional structures of mature biofilms (at 24 h) were disrupted, as determined by confocal laser scanning microscopy (CLSM), atomic force microscopy (AFM), and scanning electron microscopy (SEM), revealing a scattered morphology and a disrupted surface topology pattern. Importantly, the quantitative reverse transcription polymerase chain reaction (qRT-PCR) was employed to assess the transcriptional levels of genes related to biofilm formation and virulence in <i>R. solanacearum</i> stems following treatment with CuO NPs.
