Interpretive Summary:

Technical Abstract: Microscopic observation of root disease onset and progression is typically performed by harvesting different plants at multiple time points. This approach prevents the monitoring of individual encounter sites over time, often mechanically damages roots, and exposes roots to unnatural conditions during observation. Here, we describe a method developed to avoid these problems and its application to study Fusarium oxysporum-Arabidopsis thaliana interactions. This method enabled the three-dimensional, time-lapse imaging of both A. thaliana and F. oxysporum using confocal and multi-photon microscopy and facilitated inquiries about the genetic mechanism underpinning root pathogenesis.
