This dataset accompanies the manuscript titled "Disease Signatures in Whole Plants and Callus Culture of Arabidopsis thaliana Infected with the Fungal Plant Pathogen Fusarium graminearum" by McMullan et al. (to be submitted to Plant Cell, Tissue and Organ Culture). It includes quantitative measurements related to fungal infection severity and mycotoxin production in both whole plants and callus cultures of Arabidopsis thaliana. Three A. thaliana accessions with documented differences in susceptibility were assessed at 7, 14, and 21 days post-inoculation. Each file includes metadata for accession identity, timepoint, biological replicate, and the specific metric of interest. These datasets support analysis of host response dynamics and enable comparisons between whole-plant and callus-based systems for modeling plant-pathogen interactions. The data may also inform future work on phytosensor development and fungal secondary metabolite detection in simplified in vitro systems.

The following three files are included:
McMullan_et_al_ DON_Data_Markers_Infection_Plants_Callus_May_8_2025.csv
Contains deoxynivalenol (DON) concentration data collected from flower, seed, and callus tissues. DON is a mycotoxin produced by Fusarium graminearum and serves as a chemical indicator of pathogenic activity.
McMullan_et_al_ Ergosterol_Data_Markers_Infection_Plants_Callus_May_8_2025.csv
Reports ergosterol concentrations in callus tissues. Ergosterol is used as a biochemical proxy for fungal biomass and infection level. The data include accession, timepoint, replicate, and ergosterol measurements.
McMullan_et_al_ FAD_Data_Markers_Infection_Plants_Callus_May_8_2025.csv
Provides Fusarium-Arabidopsis Disease (FAD) visual rating scores for whole plants. These scores quantify visible disease symptoms, including wilting, chlorosis, and mycelial growth, across multiple accessions and timepoints.
