Pre-symptomatic biophysical profiling as a candidate approach for early screening of cowpea mild mottle virus tolerance in common bean
This study demonstrates that OJIP chlorophyll a fluorescence profiling can detect pre-symptomatic photosynthetic disruptions in common bean as early as one day after inoculation with Cowpea mild mottle virus, offering a rapid, non-destructive tool for distinguishing tolerant from susceptible genotypes in breeding programs.
