To summarize, this study showed that JA is able to protect date
palm seedlings against Bayoud disease through, at least in part, the
induction of peroxidase and polyphenoloxidase activities. Further
investigations on the transcriptional expression of the genes
encoding these enzymes after elicitation with JA are in progress.
A quantification of the endogenous jasmonic acid is also needed to
clarify its implication in the signaling pathways during date palm
resistance to Bayoud.
