摘要

Jasmonates (JAs) are signal molecules which elicit stress responses through JAs-responsive genes; they are also involved in developmental processes, including fruit growth and ripening. In the present study, methyl jasmonate (MJ) and n-propyl dyhydrojasmonate (PDJ) were applied to peach trees at the SI, S3 and S4 phases. In all cases, both chemicals inhibited climacteric ethylene production and delayed flesh softening leading to a ripening delay. A trascriptome profiling of JA-treated versus controlfruit indicated that MJ down-regulates genes positively involved in fruit ripening (for instance 1-aminocyclopropane-l-carboxylic acid oxidase and polygalacturonase) while up-regulates several defence-related genes, including allene oxide synthase (AOS)which is involved in JA biosynthesis, and cell wall-related genes.
