The exotic grass-fire cycle is degrading semiarid rangelands, such as the vast areas of shrub-steppe in North America now invaded by fire-promoting cheatgrass. Chemical- or bio-herbicides are sprayed onto soils to inhibit the invaders, but information on chemical- or bio-herbicide effects on plant communities is limited. We asked how the plant community responded to the bioherbicide Pseudomonas fluorescens strain ACK55 (Battalion Pro®) in comparison to the separate and combined effects of the most conventional pre-emergent chemical herbicide, imazapic (Plateau®), in two cheatgrass-invaded sagebrush-steppe sites. Plant community responses are compared with soil microbial community responses in the Larger Work, and soil microbial data are available in GenBank. Plant community responses are compared with soil microbial community responses in the Larger Work, and soil microbial sequence data were deposited to the NCBI Short Read Archive (BioProject PRJNA1254875).

,This dataset contains all raw data and R statistical code needed to reproduce the model fitting, model predictions, and data/model visualizations from the manuscript:,Lofton, L. W., Q. D. Read, H. L. Hamilton, A. E. Glenn, J. Hawkins, T. Mitchell, and S. E. Gold. Pyrrocidines A and B demonstrate synergistic inhibition of Fusarium verticillioides growth. Frontiers in Microbiology, in press. (UPDATE WHEN ACCEPTED),Fusarium verticillioides – a mycotoxigenic fungus and food safety threat – coinhabits maize kernels with Sarocladium zeae. This protective endophyte produces secondary metabolites of interest, pyrrocidines A and B, which inhibit the growth of F. verticillioides and specifically block fumonisin biosynthesis. Here, using pyrrocidine dose-response assays, we discovered a potent synergy between pyrrocidines A and B, where they functioned powerfully together to inhibit F. verticillioides growth. Further, results provided evidence that FvZBD1 confers partial tolerance to pyrrocidines, particularly pyrrocidine A, and that pyrrocidine functions through FvZBD1 to effectively eliminate fumonisin biosynthesis. Additionally, we showed that the FvABC3 (FVEG_11089) mutant, earlier described as hypersensitive to pyrrocidine, is particularly sensitive to pyrrocidine B. Thus, pyrrocidine A and B show different target specificity (FvZBD1 or FvABC3) and synergistic action.,The primary data analysis is a Bayesian generalized additive mixed model (GAMM) fit to the optical density data recorded at regular intervals from F. verticillioides strains grown in Bioscreen microtiter plates under different conditions, in a full-factorial design crossing strain (wild-type and two mutant strains) with multiple levels of pyrrocidine A and B concentration. The RMarkdown notebook imports the data, makes plots of the raw observations, fits the model to the data, and uses the posterior samples from the model to make predictions. Predictions are shown in graphical and tabular form, and evidence for effects is assessed using credible intervals of predictions, and Bayesian maximum a posteriori p-values (pMAP). A secondary analysis is presented of a dose-response assay: this is a frequentist linear model fit to a log-transformed concentration as a function of pyrrocidine type and concentration, followed by post-hoc comparisons within each pyrrocidine type. Again, results are presented in graphical and tabular form.,The following files are included:,,

The data being released were part of a project funded by the Section 40804 Ecosystem Restoration of the Bipartisan Infrastructure Law (PL-117-58) in support of advancing a national revegetation effort. Data included are from a series of DNA degradation experiments targeting the mitochondrial 16S rRNA gene of the European honeybee (Apis mellifera). This study sought to determine how various environmental conditions may affect eDNA left behind on flowers by bee visitation and thus the impact that may have on monitoring bees via eDNA. The experiments occurred in the laboratory and in the natural environment in 2022 and 2023 using store-bought potted or natural flowers spiked with Apis mellifera DNA. Flower samples were processed to elute DNA, DNA was extracted, and Apis mellifera quantified by qPCR. More information about the individual degradation experiments can be found in the Supplemental Information section.
