PCR‐based procedures for detection and quantification of Staphylococcus aureus and their application in food
Aims: To evaluate the specificity of nuc targeted primers for PCR detection of Staphylococcus aureus in different food matrices and to establish a RTQ‐PCR procedure suitable for the routine…

The obtained results support the idea that callose, oxylipins, and the JA-signaling pathway are involved in Hx-IR against B. cinerea, and support the relevance of JA-Signaling for basal defense against this necrotroph in tomato.
Silencing of OPR3 in tomato reveals the role of OPDA in callose deposition during the activation of defense responses against Botrytis cinerea.
It is shown that in tomato plants, as in Arabidopsis, OPR3 determines OPDA availability for JA biosynthesis, and that an intact JA biosynthetic pathway is required for proper callose deposition, as its pathogen-induced accumulation is reduced in SiOPR3 plants.
Absence of the endo-beta-1,4-glucanases Cel1 and Cel2 reduces susceptibility to Botrytis cinerea in tomato.

The data reported in this work support the idea that enzymes involved in cell wall metabolism play a role in susceptibility to pathogens.
A Deletion in NRT2.1 Attenuates Pseudomonas syringae-Induced Hormonal Perturbation, Resulting in Primed Plant Defenses1[C][W]
The reduced susceptibility of nrt2 mutants seems to be a combination of priming of salicylic acid-dependent defenses and reduced sensitivity to the bacterial effector coronatine.
Hexanoic acid is a resistance inducer that protects tomato plants against Pseudomonas syringae by priming the jasmonic acid and salicylic acid pathways.

It is observed that Hx seems to inhibit stomatal opening in Planta in the presence of COR, which suggests that, on infection in tomato, this treatment suppresses effector action to prevent bacterial entry into the mesophyll.

Support for the action of the 9-LOX- and α-DOX-oxylipin pathways as modulators of hormone homeostasis was the observation that lox1 dox1 seedlings are hypersensitive to the growth-inhibitory effect of ABA and showed enhanced activation of A BA-inducible marker genes as compared with wild-type plants.
Priming for JA-dependent defenses using hexanoic acid is an effective mechanism to protect Arabidopsis against B. cinerea.
Preventive and post‐infection control of Botrytis cinerea in tomato plants by hexanoic acid
Interestingly, treatments with hexanoic acid at concentrations below the MFC in hydroponic solution prior to fungal inoculation significantly reduced necrosis area, suggesting an inducer effect of plant responses for hexanoi acid treatments at these concentrations.
