Nodulin cleavage by the cysteine protease CYP35 promotes soybean root nodule senescence.

Abstract excerpt

In legumes, symbiotic root nodules undergo senescence in response to developmental or environmental cues. This process determines the maintenance and nitrogen-fixing capacity of the root nodules, but the molecular mechanisms underlying its initiation are poorly understood. The cysteine protease CYP35 is a positive regulator of nodule senescence in soybean (Glycine max), but its substrates remain unknown. Here, we...
