Abstract
Changes in primary metabolism of lettuce, Lactuca sativa L. (cv. Cobham Green), induced by compatible interaction with the biotrophic oomycete pathogen Bremia lactucae Regel (race BL 16), under two intensities of illumination in the presence and absence of exogenous cytokinins were studied by chloro...

We investigated the basis for resistance to the downy mildew agent Hyaloperonospora arabidopsidis ex parasitica (Hpa) in a global sample of A. thaliana. We implemented a combined genome-wide mapping of resistance using populations of recombinant inbred lines and a collection of wild A. thaliana acce...

We describe for the first time the molecular mechanism of resistance to a carboxylic acid amide (CAA) fungicide. We identified a family of four cellulose synthase (CesA) genes containing conserved domains that are found in all processive glycosyltransferases. Phylogenetic analysis revealed their clo...

Abstract
Four isolates of Peronophythora litchii with resistance to carboxylic acid amide (CAA) fungicides were selected on fungicide-amended agar. These isolates had various levels of resistance, as evidenced by their resistance factor (RF), which is the 50% effective concentration (EC(50)) value of a parti...

Abstract
Methyl salicylate (MeSA), which is synthesized in plants from salicylic acid (SA) by methyltransferases, has roles in defense against microbial and insect pests. Most of the MeSA that accumulates after pathogen attack is synthesized by benzoic acid/SA carboxyl methyltransferase 1 (AtBSMT1). To inves...

Abstract
We have assessed the implication of the transcriptional regulator OCP3 in SA- and JA-dependent induced defenses. Through a series of double mutant analyses, we conclude that SA-dependent defense signaling does not require OCP3. However, we found that ocp3 plants are impaired in a Pseudomonas fluores...

Abstract
Dual epidemics are defined as epidemics developing on two or several plant organs in the course of a cropping season. Agricultural pathosystems where such epidemics develop are often very important, because the harvestable part is one of the organs affected. These epidemics also are often difficult...

Abstract
We showed that, as for ABA, the elicitor-induced stomatal closure is mediated by reactive oxygen species (ROS) production in guard cells. In plants, we observed that the protection against downy mildew induced by some elicitors is probably not due only to effects on stomatal movements or to a guard-...

Both plant and animal cells use PCD as a powerful weapon against biotrophic pathogens, including viruses, which draw their nutrition from living tissue. Thus, diverse biotrophic pathogens have evolved many mech...

These molecules, termed effectors, commonly target the host defense signaling pathway...
