The Arabidopsis NIMIN cycle – shaping PR gene expression in the course of systemic acquired resistance
Felix Maier, Meike Hermann, Ashir Masroor, Artur J. P. Pfitzner, Ursula M. Pfitzner

Abstract: Nonexpressor of Pathogenesis-Related Genes1 (NPR1) is a master regulator of
systemic acquired resistance (SAR). NPR1 is part of a transcription complex mediating salicylic
acid (SA)-induced expression of Pathogenesis-Related (PR) Protein1 genes through co-operation
between different proteins. TGA transcription factors link NPR1 to the PR-1 promoter region,
while NIMIN proteins control NPR1 activity. Based on gene expression analysis, protein-protein
interaction assays and functional in planta studies, we suggest that NIMIN3 suppresses PR gene
expression in unchallenged plants. NIMIN2 promotes transcription of early SA- and NPR1-
dependent genes, whereas NIMIN1 becomes active only after NIMIN2 by blocking SA- and
NPR1-dependent gene expression. The repressional block is relieved with increasing levels of SA
to yield strong, sudden and coordinate expression of the late SAR-induced PR genes.

Effect of nitrogen fertilisation of strawberry plants on the efficacy of defence-stimulating biocontrol products against Botrytis cinerea
ppe C. Nicot, Marc Bardin, François Debruyne, Magali Duffaud, François Lecompte, Laurent Neu and Michel Pascal

Abstract: Although Nitrogen (N) is a key component in many compounds implicated in hostpathogen
interactions, little is known on the possible effect of N fertilisation of the plant on the
efficacy of defence-stimulating biocontrol agents. In the present work we examined the effect of
five levels of N nutrition on the susceptibility of strawberry leaves to Botrytis cinerea and on the
protective efficacy of two biocontrol products presumed to induce plant defence mechanisms.
Two days after the application of the biocontrol products, batches of leaf discs were excised,
inoculated with B. cinerea and incubated in conditions conducive to disease development. Plant
fertilisation had a highly significant effect on disease development for both strains of B. cinerea
tested and it significantly influenced the efficacy of the biocontrol products. Possible hypotheses
and the relevance of these results for integrated protection are discussed.

Diversity in susceptibility of Botrytis cinerea to biocontrol products inducing plant defence mechanisms
Marc Bardin, Morgane Comby, Ruben Lenaerts and Philippe C. Nicot

Abstract: The development of plant defence stimulants to increase host resistance represents an
attractive alternative to fungicides for the protection of crops against plant pathogens. In this
study we evaluated the efficiency of 14 products presumed to induce plant defence mechanisms
against Botrytis cinerea on tomato and lettuce. Two days after the application of the products,
tomato and lettuce leaves were inoculated with B. cinerea and incubated in conditions conducive
to disease development. Out of 14 products tested, Serenade Max® (Bacillus subtilis QST713)
proved to have a significant protective efficacy against B. cinerea on both plants. To assess the
presence of low susceptibility to Serenade Max in populations of B. cinerea, the protective
efficacy of this product was evaluated against 20 strains differing in their geographic origin, host
of isolation and level of aggressiveness. To this end, tomato and lettuce leaves were treated with
Serenade Max two days before inoculation. The efficiency of the product was significantly
influenced by the isolate of B. cinerea tested with protection levels ranging from 40% to 86% on
tomato leaves and 0 to 80% on lettuce leaves. No correlation was observed between the level of
aggressiveness of B. cinerea strains and the protection provided by the biocontrol agent.

Characterization of Trichoderma harzianum T39-induced resistance of grapevine against downy mildew
Michele Perazzolli, Marco Moretto, Paolo Fontana, Alberto Ferrarini, Riccardo Velasco, Claudio Moser, Massimo Delledonne, Ilaria Pertot

Abstract: Downy mildew is one of the most destructive grapevine diseases and its control is
based on the application of fungicides. There is increasing interest to reduce reliance on
pesticides for disease control in viticulture and to focus on alternative methods, such as
biocontrol agents. In grapevine, Trichoderma harzianum T39 (T39) activates a plant-mediated
resistance and significantly reduces downy mildew symptoms. Our aim is to characterize the
molecular mechanisms activated by T39 in grapevine, in order to identify genes associated with
the induced resistance against Plasmopara viticola.

Diversity in the effect of an extract from Fallopia sachalinensis on isolates of cucurbit powdery mildews grown on melon
Marc Bardin, Annegret Schmitt, Philippe C. Nicot

Abstract: Powdery mildew caused by Podosphaera xanthii and Golovinomyces cichoracearum
is one of the principal diseases on cucurbit crops in temperate climates. In order to control this
disease, various biological methods, including induced resistance by the use of extracts from
Fallopia sachalinensis, have been identified. This study was conducted to characterise the
diversity of susceptibility to this plant extract among 52 isolates of P. xanthii and 5 isolates of G.
cichoracearum
collected from various cucurbit species in different production areas. To this end,
disks excised from melon leaves were soaked in a preparation of F. sachalinensis extract (1%
w/v) or in a control solution, inoculated with fresh conidia of powdery mildew 24 hours after
treatment and placed in a growth chamber. Ten days after inoculation, symptoms were rated in
classes based on a visual estimation of the leaf area infested by powdery mildew. Additionally,
spore production on the leaf disks was assessed. The plant extract significantly decreased the
severity of disease for all the powdery mildew isolates tested. On average, spore production was
only ca. 20% in presence of the plant extract relative to the untreated control. However, the
extent of the reduction in spore production varied widely among isolates.

Induction of resistance to Botrytis cinerea by ethylene is evolutionary conserved but ethylene inhibits vanillylnonanamide induced resistance
José Diaz, Rafael Carballeira, Javier Veloso and Tania García

Abstract: Ethylene is a plant hormone involved in resistance against pathogens, mainly
necrotrophs as Botrytis cinerea. In the present paper we demonstrate the ability of ethylene to
induce resistance against Botrytis cinerea and Phytophthora capsici in pepper. Jasmonic acid was
also able to induce resistance against B. cinerea, but salicylic acid was not. In order to test if this
ability to mediate resistance is evolutionary conserved, we tested ethylene in four plant species:
Phaseolus vulgaris (Leguminosae), Zinnia elegans (Compositae), Zea mays (Poaceae, a
monocotyledonous plant) and Polypodium vulgare (a fern). In all the cases ethylene caused
resistance against B. cinerea. In pepper, ethylene induced the expression of CaSC1, a
sesquiterpene cyclase involved in phytoalexin biosynthesis, and chitinase activity. Both CaSC1
and chitinase could be related to the observed resistance. Vanillylnonanamide is a pungent
compound present in some pepper fruits. This compound was also able to induce resistance
against Botrytis when exogenouly applied to pepper plants. The effect of vanillylnonanamide was
also tested in the tomato ethylene signalling mutant Never ripe, where the induction worked, but
in the wild type no induced resistance was observed. A similar result was obtained with salicylic
acid: it only induced resistance to Botrytis cinerea in Never ripe, but not in the wild type. These
results suggest a cross-talk between ethylene and salicylic acid in the vanillylnonanamide
induced resistance. A non pungent capsaicinoid analogue, the capsinoid vanillylnonanoate, was
also able to induce resistance against B. cinerea and P. capsici in pepper.

Priming agent hexanoic acid-enhanced resistance in mandarin Fortune against Alternaria alternate
Eugenio Llorens, Gemma Camañes, Victoria Pastor, Leonor Lapeña and Pilar García-Agustín

Abstract: Previous research works by our group have demonstrated that hexanoic acid
(priming agent, Hx) induces resistance in Solanum lycopersicum and Arabidopsis
thaliana plants against Botrytis cinerea. Alternaria alternata is the cause of abandonment
of the hybrid mandarin Fortune (C. tangerina x C. clementina) due to Alternaria brown
spot damage. In this work, induced resistance against citrus plants has been assessed. In
order to study the mechanisms implied in IR-Hx against A. alternata, a histochemical
analysis was carried out to assess the effect of reactive oxygen species ROS and callose
deposition on production. We previously demonstrated that the number of infected leaves
and the diameter of infection diminished when treating citrus plants with hexanoic acid
1mM, and that the physiological parameters improved. A. alternata infection quickly
increased H2O2 and superoxide ions levels in tissues. However, the Hx priming agent
reduced the H2O2 level in leaves by at least four times on day 5 post-infection if
compared with control plants. Likewise, superoxide lowered in treated plants.
Furthermore, the priming agent seemed to considerably accumulate callose around the
necrotic area, which could delay the development of infection and induce a faster and
stronger accumulation of OPDA, JA-Ile and ABA. Hence, the obtained results support
the idea that oxygen species ROS, callose and the JA pathway could be involved in Hx-
IR in citrus plants against A. alternata.

Salicylic acid signals through two conserved domains in the C-terminal third of NPR1 and some NPR1-like proteins
David Neeley, Felix Maier, Artur J. P. Pfitzner and Ursula M. Pfitzner

Abstract: Nonexpressor of Pathogenesis-Related Genes1 (NPR1) is a master regulator of
systemic acquired resistance (SAR). NPR1 is part of a transcription complex mediating
salicylic acid (SA)-induced expression of Pathogenesis-Related (PR) Protein1 genes
through co-operation between different proteins. TGA transcription factors link NPR1 to
the PR-1 promoter region, while NIMIN proteins control NPR1 activity. The NPR1 gene
is expressed constitutively, and the protein is activated only in response to SA. From
yeast one-hybrid and yeast two-hybrid analyses, we conclude that the SA signal is likely
to target NPR1 directly. SA signal transduction occurs through two conserved domains in
the C-termini of NPR1 and some NPR1-like proteins. One domain comprises the pentaamino
acid motif LENRV. The other domain comprises the binding site for the SAinduced
NIMIN1 and NIMIN2-type proteins.

A specific homeostasis between callose and H2O2 is needed for an intact BABA-IR against P cucumerina
Victoria Pastor, Estrella Luna, Jurriaan Tonn, Pilar García-Agustín, Miguel Cerezo, Victor Flors

Abstract: Upon appropriated stimulus plants can activate basal defense mechanisms by reacting
faster and stronger to a biotic challenge reducing the chances for pathogen invasion. Among
many responses, the production of reactive oxygen species (ROS) and callose deposition are the
earliest events in defense. In the present work, we study the ROS and callose interplay during
β-aminobutyric acid (BABA)-induced priming against the necrotrophic fungus Plectosphaerella
cucumerina. Mutants affected in cell redox homeostasis show differences in callose depositions,
as well as in basal and induced defense responses. Our findings suggest that PAD2 which encodes
the enzyme that catalizes the first step of the synthesis of glutathion (GSH) plays a revelant role
in basal and induced resistance. On the other hand, the mutant rbohD, which shows low levels of
H2O2, has not altered its basal resistance but is blocked in BABA-IR. In conclusion, our findings
demonstrate that a specific redox regulation is necessary for BABA-IR against P cucumerina
which is dependent on PAD2 and RBOHD but not on VTC1 and CAT2.

Effect of environmental factors on the interaction plant – pathogen – Bacillus amyloliquefaciens S499
Ilaria Pertot, Taha Hosni, Lorenzo Pedrotti, Gerardo Puopolo, Emmanuel Jourdan, Marc Ongena

Abstract: Temperatures and water stress are generally considered the most detrimental
factors for survival and effectiveness of microbial biocontrol agents. The role played by
these environmental factors on the biocontrol activity of Bacillus amyloliquefaciens S499
has been investigated in this work. On this purpose, the effect of temperature on growth,
surfactin production and the ability to induce systemic resistance in plants have been
evaluated in vitro and in vivo.
