Other claims from this paper (14)

Intervention effect Rh-Est-C12 reduced wheat Z. tritici disease severity by 41%.
Intervention effect Rh-Est-C12 had only a slight effect on wheat leaf gene expression.
Intervention effect Rh-Est-C12 had only a slight effect on wheat leaf metabolite accumulation.
Observation 24 differentially expressed genes (DEGs) were recorded under elicitation modalities.
Observation 11 differentially accumulated metabolites (DAMs) were recorded under elicitation modalities.
Observation 25 DEGs were recorded under priming modalities.
Observation 17 DAMs were recorded under priming modalities.
Observation Most wheat transcript and metabolite changes were down-regulations.
Observation Only a few wheat DEGs and DAMs associated with pathogen resistance were identified.
Observation Wheat gene expression showed transient early regulation at 2 days after treatment.
Mechanism Authors infer wheat protection by Rh-Est-C12 mainly through direct antifungal activity.
Mechanism Authors infer a lesser contribution of induced wheat defenses to Rh-Est-C12 protection.
Observation Rh-Est-C12 did not cause major alterations in wheat metabolism.
Recommendation Authors highlight Rh-Est-C12 as a low-fitness-cost option to control Z. tritici.

Mark C. Derbyshire; Amir Mirzadi Gohari; Rahim Mehrabi; et al. Scientific Reports 2018. doi:10.1038/s41598-018-35223-8

Other claims from this paper (5)

Observation The ZtPpt deletion strains were non-melanised.
Observation The ZtPpt deletion strains were non-pathogenic on wheat.
Mechanism Lysine auxotrophy was the main contributing factor for loss of virulence of the ZtPpt-deficient fungus.
Intervention effect Loss of siderophore production or of melanisation caused no reduction in virulence.
Recommendation Ppt and the lysine biosynthesis pathway are proposed as potential targets for fungicides effective against Z. tritici.
