  abstract = {{P}ineapple ({A}nanas comosus ({L}.) {M}err.) is a non-climacteric tropical fruit whose ripening could be accompanied by oxidative processes and the concurrent activation of enzymatic and non-enzymatic reactive oxygen species ({ROS}) scavenging systems. {T}o better understand the variability of these processes among climatic environments or genotypes in pineapple, the temporal expression dynamics for genes encoding oxidative and antioxidative stress enzymes were analyzed by real-time {RT}-{PCR} during fruit development and ripening, among three cultivars: {Q}ueen {V}ictoria, {F}lhoran 41 and {MD}-2 hybrid, and in two climatic areas. {P}ineapple development and ripening involved changes in the levels of transcripts encoding for polyphenol oxidase and transcripts involved in the first steps of the phenylpropanoid pathway and in the balance of {ROS}, especially those encoding for ascorbate peroxydase and metallothioneins, regardless of the cultivar. {O}ur results confirm the same dynamic in gene expression from the two environmental crop areas, however climatic conditions influenced the level of the expression of the major transcripts studied that were linked to these oxidative and antioxidant metabolisms. {MT}3a and {MT}3b transcripts were not influenced by genetic factor. {T}he genetic effect was not significant on the various transcripts linked to the first steps of the phenylpropanoid pathway and to phenol oxidation, except 4{CL} ones. {I}n ripe pineapple, highly significant relationships were found between the contents in antioxidant metabolites, i.e., ascorbic acid and total phenolic compounds, and the transcript levels of genes involved in the enzymatic {ROS}-scavenging system and in the biosynthesis or regeneration of {ROS}-scavenging compounds, like phenylpropanoids, ascorbic acid, metallothioneins.},
