The novel elicitor AsES triggers a defense response against Botrytis cinerea in Arabidopsis thaliana

Hael-Conrad, V. ; Abou-Mansour, Eliane ; Díaz-Ricci, J.-C. ; Métraux, Jean-Pierre ; Serrano, Mario

In: Plant Science, 2015, vol. 241, p. 120–127

AsES (Acremonium strictum Elicitor and Subtilisin) is a novel extracellular elicitor protein produced by the avirulent isolate SS71 of the opportunist strawberry fungal pathogen A. strictum. Here we describe the activity of AsES in the plant-pathogen system Arabidopsis thaliana–Botrytis cinerea. We show that AsES renders A. thaliana plants resistant to the necrotrophic pathogen B. cinerea, both...

The microbiome of the leaf surface of Arabidopsis protects against a fungal pathogen

Ritpitakphong, Unyarat ; Falquet, Laurent ; Vimoltust, Artit ; Berger, Antoine ; Métraux, Jean-Pierre ; L'Haridon, Floriane

In: New Phytologist, 2016, p. -

We have explored the importance of the phyllosphere microbiome in plant resistance in the cuticle mutants bdg (BODYGUARD) or lacs2.3 (LONG CHAIN FATTY ACID SYNTHASE 2) that are strongly resistant to the fungal pathogen Botrytis cinerea. The study includes infection of plants under sterile conditions, 16S ribosomal DNA sequencing of the phyllosphere microbiome, and isolation and high coverage...

The inter-kingdom volatile signal indole promotes root development by interfering with auxin signalling

Bailly, Aurélien ; Groenhagen, Ulrike ; Schulz, Stefan ; Geisler, Markus ; Eberl, Leo ; Weisskopf, Laure

In: The Plant Journal, 2014, vol. 80, no. 5, p. 758–771

Recently, emission of volatile organic compounds (VOCs) has emerged as a mode of communication between bacteria and plants. Although some bacterial VOCs that promote plant growth have been identified, their underlying mechanism of action is unknown. Here we demonstrate that indole, which was identified using a screen for Arabidopsis growth promotion by VOCs from soil-borne bacteria, is a potent...

Production of reactive oxygen species and wound-induced resistance in Arabidopsis thaliana against Botrytis cinerea are preceded and depend on a burst of calcium

Beneloujaephajri, Emna ; Costa, Alex ; L’Haridon, Floriane ; Métraux, Jean-Pierre ; Binda, Matteo

In: BMC Plant Biology, 2013, vol. 13, no. 1, p. 160

Background: Wounded leaves of Arabidopsis thaliana produce reactive oxygen species (ROS) within minutes after wounding and become resistant to the pathogenic fungus Botrytis cinerea at a local level. This fast response of the plants to the wound is called wound-induced resistance (WIR). However the molecular mechanisms of this response and the signal cascade between the wound and ROS production...
