Homeostasis between the cytoplasmic plant hormone salicylic acid (SA) and its' inactive,vacuolar storage forms, SA-2-O-β-D-glucoside (SAG) and SA-β-D-Glucose Ester (SGE), regulates thefine-tuning of defense responses to biotrophic pathogens in Arabidopsis thaliana. This protocoldescribes a simplified, optimized procedure to extract and quantify...

Plant lipid transfer proteins are small soluble extracellular proteins that are able to bind and transfer a variety of lipids in vitro. Recently, it has been proposed that lipid transfer proteins may play a key role in plant defence mechanisms, especially during the induction of systemic acquired resistance. However, very little is known about...

Background: Interactions between pathogenic oomycetes and microbiota residing on the surface of the host plant root are unknown, despite being critical to inoculum constitution. The nature of these interactions was explored for the polyphagous and telluric species Phytophthora parasitica. Results: Composition of the rhizospheric microbiota of...

Vertebrate females transfer antibodies via the placenta, colostrum and milk or via the egg yolk to protect their immunologically immature offspring against pathogens. This evolutionarily important transfer of immunity is poorly documented in invertebrates and basic questions remain regarding the nature and extent of parental protection of...

The plant pathogen Phytophthora parasitica forms a biofilm on the host surface. The biofilm transcriptome is characterized by the expression of PPMUCL1/2/3 (PHYTOPHTHORA PARASITICA MUCIN-LIKE) genes, which we report here to be members of a new, large mucin-like gene family restricted to the oomycete lineage. These genes encode secreted proteins...

In this paper we describe our strategy to unravel the connection between plant defenses and plant resistance to pests. With tomato (Solanum lycopersicum) as the reference plant, our ambition is to screen different plant defense stimulators (SPD) and measure (i) the resulting protection leve! towards Phytophthora parasitica, Botrytis cinerea and...

Prior exposure to microbial-associated molecular patterns or specific chemical compounds can promote plants into a primed state with stronger defence responses. β-aminobutyric acid (BABA) is an endogenous stress metabolite that induces resistance protecting various plants towards diverse stresses. In this study, by integrating BABA-induced...

In nature, the organisation of microbial species into biofilms has a great influence on local environments and in human or plant diseases. This important trait of prokaryotes and eukaryotes is poorly understood while the knowledge of the related biological processes could constitute a novel base for controlling diseases. A study is developed on...

Root knot nematodes are obligate phytoparasites that invade the roots of important crop plants causing severe economic losses. Arbuscular Mycorrhizal Fungi (AMF) are soil borne microorganisms that establish mutualistic associations with the roots of most plants. AMF have been frequently indicated to help their host to attenuate the damage...
