摘要： Cowpea ( Vigna unguiculata (L.) Walp) is prone to water loss and shriveling after harvest. Sodium nitroprusside (SNP) as a generator of nitric oxide acts as a senescence retarding agent. In this study, the influence of SNP on cowpea senescence during storage at 15 degrees C for 8 d has been investigated. SNP treatment (0.3 mM) decreased the mass loss and maintained the hardness, total chlorophyll, and vitamin C content of the cowpeas. SNP suppressed the expression of the genes involved in ethylene signaling ( SAM1 , ETR2 , ERFs ), cell wall disassembly ( PE2 , PL5 , PG ), and the lignin synthesis genes ( 4CL , CCR , and CAD ), while inducing the expression of defense and resistance -related genes ( KCS , ABCG , BAK1 , PR -4 , and CpPR3 ). The major differentially accumulated metabolites in SNP -treated cowpeas were flavonoids, phenolic acids, and alkaloids. SNP -induced differentially expressed proteins that are involved in lignification (4CL, CAD, and POD), texture -related processes (PL5, PE, and EG), and disease resistance (PBSI, PR1, and SCP). Overall, the study revealed that SNP -generated NO suppressed ethylene signaling, inhibited lignin accumulation, regulated wax, suberin, and cuticle biosynthesis, and enhanced defense processes, resulting in higher -quality cowpeas than those of the untreated controls.
