- Intervention effect Methyl jasmonate induced sesquiterpene production in Cabernet Sauvignon grape cell cultures.
- Intervention effect Jasmonic acid activated sesquiterpene synthesis.
- Intervention effect Adding salicylic acid to MeJA prevented sesquiterpene production.
- Intervention effect Two terpene synthases were upregulated after MeJA treatment.
- Intervention effect Two terpene synthases were upregulated after JA treatment.
- Observation Tannin and stilbene pathway genes responded differentially to treatments.
- Intervention effect Tannins accumulated to higher levels in MeJA treated cells.
- Intervention effect Tannins accumulated to higher levels in JA treated cells.
- Intervention effect Tannin pathway key gene expression was over twofold higher with MeJA than control and MeJA plus SA.
- Intervention effect Tannin pathway key gene expression was over twofold higher with JA than control and MeJA plus SA.
- Observation Stilbenes accumulated in all three treatments.
- Association Stilbene levels correlated mostly with STS2 expression.
- Association Several transcription factors had expression patterns matching induction patterns for the three pathways.
