It is shown that GAMT1 expression is also localized mostly to seed, suggesting a role in seed development and suggesting that the mature mutant seeds contained higher levels of active GAs than wild-type seeds.
Characterization of a petunia acetyltransferase involved in the biosynthesis of the floral volatile isoeugenol.

- BiologyThe Plant Journal
- 2007
Biochemical characterization of the protein encoded by this gene showed that it has acetyltransferase activity and is most efficient with coniferyl alcohol among the alcohol substrates tested, supporting the conclusion thatConiferyl acetate is the substrate of isoeugenol synthase.

The present study shows that induction of capsidiol production in the C. annuum is mediated by PLA2 activation.
Meso‐dihydroguaiaretic acid and licarin A of Machilus thunbergii protect against glutamate‐induced toxicity in primary cultures of a rat cortical cells
- C. Ma, So R. Kim, Jinwoong Kim, Y. C. Kim
- Biology, ChemistryBritish Journal of Pharmacology
- 1 November 2005
The results suggest that MDGA and licarin A significantly protect primary cultured neuronal cells against glutamate‐induced oxidative stress, via antioxidative activities.
Neuroprotective lignans from the bark of Machilus thunbergii.
Isoguaiacin, meso-dihydroguaiaretic acid, licarin A and (+)-guaiacIn had significant neuroprotective activities against glutamate-induced neurotoxicity in primary cultures of rat cortical cells at concentrations ranging from 0.1 microM to 10.0 microM.
