Exogenous Application of ENOD40 and CEP1 Peptides Boosts Symbiotic Signaling Gene Expression and Productivity in Common Bean.

ABSTRACT: Small signaling peptides play crucial roles in the regulation of legume-rhizobia symbiosis, yet their potential as exogenous biostimulants remains largely unexplored. In this study, we evaluated the effects of foliar application of the synthetic peptides ENOD40 and CEP1 on common bean (Phaseolus vulgaris) under both greenhouse and field conditions. Using a factorial design, we examined gene expression patterns, nodulation parameters, and yield-related traits in response to peptide treatments alone or in combination with Rhizobium. Results showed that ENOD40 and CEP1 significantly enhanced the transcription of key symbiotic signaling genes (PvENOD40, PvSYMRK, PvCCaMK, PvCYCLOPS, PvVAPYRIN) and modulated defense-related genes (PvAOS,
