dc.description.abstractBACKGROUND: THE CUTICLE PLAYS AN IMPORTANT ROLE IN THE SURVIVAL OF PLANTS, AND IT IS IMPORTANT TO PRESERVE THE QUALITY OFFLESHYFRUITS LIKE SWEET CHERRY. PLANT HORMONES PLAY A ROLE IN CUTICLE FORMATION. IN THIS SENSE, JASMONATES HAVE BEEN SHOWN TO INDUCECUTICLE BIOSYNTHESIS, BUT UNTIL TODAY THIS HAS NOT BEEN DEMONSTRATED IN SWEET CHERRY FRUIT. THEREFORE, THE EFFECT OF EXOGENOUSMETHYL JASMONATE (MEJA) APPLICATION AT THE FRUIT SET STAGE ON THE EXPRESSION LEVELS OF CUTICLE SYNTHESIS-RELATED GENES AND THEWAX COMPOSITION OF THE ISOLATED CUTICLE WAS STUDIED IN DEVELOPING AND RIPE FRUITS OF SWEET CHERRY (PRUNUS AVIUM?BING?),RESPECTIVELY.RESULTS: MEJA TREATMENT RESULTED IN UP-REGULATION OF THE CUTICLE BIOSYNTHESIS-RELATED GENE EXPRESSION, SUCH ASPAWINA,PAWINB,PAKCS1,PAKCS6,PALACS1,PALACS2,PAWS, ANDPAWBC11. THESE GENES PLAY A VITAL ROLE IN THE ELONGATION AND TRANSPORT OF FATTYACIDS, AND WAX BIOSYNTHESIS. ANALYSIS OF CUTICULAR COMPONENTS IN RIPE FRUIT SHOWED AN INCREASE IN LONG-CHAIN LINEAR ALIPHATIC WAXCOMPOUNDS, PARTICULARLY C27, C28, C29, C30, AND C31 ALKANES.CONCLUSION: EXOGENOUS MEJA APPLICATION AT THE FRUIT SET STAGE OF SWEET CHERRY HAS A SIGNIFICANT EFFECT ON THE WAX COMPOSITION OFTHE RIPE FRUIT CUTICLE, PARTICULARLY IN TERMS OF ALKANE BIOSYNTHESIS. THE RESULTS OF THIS STUDY MAY PROVIDE INSIGHTS INTO THE REGU-LATION OF CUTICLE BIOSYNTHESIS BY JASMONATES AND BE USEFUL FOR IMPROVING FRUIT QUALITY AND STORAGE LIFE.© 2023 SOCIETY OF CHEMICAL INDUSTRY.
