Title	Shedding light on plant proteolysis: genetically encoded fluorescent sensors as tools for profiling protease activities
Description	Proteolysis is a universal process, as proteases play a pivotal role in modulating numerous signaling pathways. By hydrolyzing peptide bonds within their target proteins, proteases control their fate and function. Understanding the temporal and spatial dynamics of proteolytic events, including the proteases that execute them, is crucial for elucidating their particular roles across diverse biological processes. In this study, we developed and characterized a set of genetically encoded Förster resonance energy transfer (FRET)-based reporters for the detection of various proteolytic activities in plants. Our sensors reliably reported the activity of specific proteases, exhibiting performance comparable to established detection systems. In addition, we engineered variants capable of detecting the spatial dynamics of metacaspase-triggered proteolysis after wounding and during programmed cell death in roots. The implementation of these tools in plant research opens new opportunities to explore proteolytic mechanisms with enhanced precision. We demonstrate the feasibility of the FRET-based sensors to detect various activities in vivo with high spatiotemporal resolution. Overall, these biosensors constitute a versatile toolbox for probing protease function within its native cellular context, paving the way for deeper insights into plant biology and signaling. This dataset includes a targeted shotgun proteomics experiment designed to identify the specific endoproteolytic cleavage products generated from the FRET(VRPR) biosensor.
