J Exp Bot. 2002;53:1283-304 pubmed..All these factors must be considered in order to evaluate the significance of glutathione as a signalling component during development, abiotic stress, or pathogen attack. ..
- Lebeau A, Reverchon S, Gaubert S, Kraepiel Y, Simond Côte E, Nasser W, et al. The GacA global regulator is required for the appropriate expression of Erwinia chrysanthemi 3937 pathogenicity genes during plant infection. Environ Microbiol. 2008;10:545-59 pubmed publisher..GacA might partly act by negatively controlling the expression of the pecT gene encoding the global repressor PecT, indicating a hierarchy in the pathways involved in the E. chrysanthemi regulatory network. ..
- Remy E, Meyer M, Blaise F, Chabirand M, Wolff N, Balesdent M, et al. The Lmpma1 gene of Leptosphaeria maculans encodes a plasma membrane H+-ATPase isoform essential for pathogenicity towards oilseed rape. Fungal Genet Biol. 2008;45:1122-34 pubmed publisher..Silencing experiments, expression analyses and phylogenetic studies allowed us to highlight the essential role assumed by the Lmpma1 isoform in L.maculans pathogenicity. ..
- Simon C, Langlois Meurinne M, Bellvert F, Garmier M, Didierlaurent L, Massoud K, et al. The differential spatial distribution of secondary metabolites in Arabidopsis leaves reacting hypersensitively to Pseudomonas syringae pv. tomato is dependent on the oxidative burst. J Exp Bot. 2010;61:3355-70 pubmed publisher..Overall, the study demonstrates that ROS availability influences both the amount and the pattern of infection-induced SM accumulation. ..
- Guinebretiere M, Nguyen The C, Morrison N, Reich M, Nicot P. Isolation and characterization of antagonists for the biocontrol of the postharvest wound pathogen Botrytis cinerea on strawberry fruits. J Food Prot. 2000;63:386-94 pubmed..5). The efficiency of the bacterial antagonists on fruit wounds was related to their growth and nutritional properties. ..
- Venisse J, Barny M, Paulin J, Brisset M. Involvement of three pathogenicity factors of Erwinia amylovora in the oxidative stress associated with compatible interaction in pear. FEBS Lett. 2003;537:198-202 pubmed..Two other pathogenicity factors of the bacteria, the HrpW effector and the capsule, do not seem to play any role in the elicitation of the oxidative burst nor in the protection of the bacteria. ..
- Galiana E, Fourre S, Engler G. Phytophthora parasitica biofilm formation: installation and organization of microcolonies on the surface of a host plant. Environ Microbiol. 2008;10:2164-71 pubmed publisher..They may affect plant-pathogen interactions by serving as reservoirs for pathogenic microorganisms, as protecting niche against host defences or as structures for infecting populations...
- Navarro L, Jay F, Nomura K, He S, Voinnet O. Suppression of the microRNA pathway by bacterial effector proteins. Science. 2008;321:964-7 pubmed publisher..These results provide evidence that, like viruses, bacteria have evolved to suppress RNA silencing to cause disease. ..
- Desprez Loustau M, Vitasse Y, Delzon S, Capdevielle X, Marcais B, Kremer A. Are plant pathogen populations adapted for encounter with their host? A case study of phenological synchrony between oak and an obligate fungal parasite along an altitudinal gradient. J Evol Biol. 2010;23:87-97 pubmed publisher..Phenotypic plasticity was the major cause of the observed variation in the phenology of the fungal populations. ..
- Dubreuil Maurizi C, Vitecek J, Marty L, Branciard L, Frettinger P, Wendehenne D, et al. Glutathione deficiency of the Arabidopsis mutant pad2-1 affects oxidative stress-related events, defense gene expression, and the hypersensitive response. Plant Physiol. 2011;157:2000-12 pubmed publisher..Together, our results indicate that the pad2-1 mutation is related to a decrease in GCL protein and that the resulting glutathione deficiency negatively affects important processes of disease resistance. ..
