Other claims from this paper (12)
- Intervention effect Artemisia absinthium essential oil had a toxic effect against Fusarium oxysporum Fol in vitro.
- Intervention effect Tomato seedlings from AEO-pretreated seeds grown hydroponically were protected against Fol.
- Intervention effect Disease symptoms (water and fresh weight loss, tissue necrosis, chlorosis) were less pronounced in AEO-treated tomato seedlings.
- Intervention effect AEO increased callose deposition and reactive oxygen species production on tomato seed surfaces.
- Intervention effect The essential oil seed coating primed a durable tomato seedling defense against the fungus at later stages of plant development.
- Intervention effect AEO treatment on seeds induced transcriptomic and metabolic changes in seedlings after 12 days.
- Observation Vanillic acid, coumarin and lycopene were induced in tomato in the presence of Fol.
- Observation Oleamide and an unknown metabolite of m/z 529 were induced in tomato in the presence of Fol.
- Intervention effect The StNRPD2 gene, involved in RdDM, was highly induced in the presence of AEO.
- Intervention effect The host methionine cycle was altered by AEO through high induction of S-adenosyl methionine transferases.
- Mechanism The authors suggest AEO treatment could induce de novo epigenetic changes in tomato, modulating the speed and extent of its immune response to Fol.
- Recommendation The authors propose the EO seed coating as a new strategy to prime durable tomato resistance.
