TLDR
The effect of 6-furfurylaminopurine (kinetin) on the HR of potato tubers challenged with Phytophthora infestans was investigated and a hypothetical model linking senescence and HR physiology via oxidative damage is briefly presented.About:

Evolution of Hormone Signaling Networks in Plant Defense
TL;DR: In this article, the authors explore the evolution of defense hormone signaling networks by combining the model plant-based knowledge about molecular components mediating phytohormone signaling and cross talk with available genome information of other plant species.
Journal ArticleDOI
Markers for hypersensitive response and senescence show distinct patterns of expression.
TL;DR: The result indicates that although there is evidence of some cross-talk between both cell death pathways, spatial and temporal characteristics of activation for these markers during hypersensitive response and senescence are distinct, which indicates that these markers are relatively specific for different cell death programs.

Ecology of Microbial Saprophytes and Pathogens in Tissue Culture and Field-Grown Plants: Reasons for Contamination Problems In Vitro
TL;DR: This comparison and the measured reduction in contamination after improvements in working practices in the laboratory, conclusions can be drawn about the importance of the explant and the laboratory as sources of contamination.

TL;DR: A novel transgenic approach enabling autoregulated cytokinin synthesis in response to pathogen infection showed that cytokinins mediate enhanced resistance against the virulent hemibiotrophic pathogen Pseudomonas syringae pv tabaci.

Colorimetric Method for Determination of Sugars and Related Substances
TL;DR: In this article, a method was developed to determine submicro amounts of sugars and related substances using a phenol-sulfuric acid reaction, which is useful for the determination of the composition of polysaccharides and their methyl derivatives.

Rapid Stimulation of an Oxidative Burst during Elicitation of Cultured Plant Cells: Role in Defense and Signal Transduction
TL;DR: The results suggest that H(2)O(2), implicated as a second messenger of hormone-stimulated metabolic changes in some animal cells, also plays an important role in inducing subsequent defense responses such as phytoalexin production.
Journal ArticleDOI
The role of free radicals in senescence and wounding.
TL;DR: Several lines of evidence suggest that degradation of lipids in senescing membranes and the ensuing release of free fatty acids initiate oxidative deterioration by providing substrate for lipoxygenase, and membranes are primary targets of free radical damage.

Volatile Products of the Lipoxygenase Pathway Evolved from Phaseolus vulgaris (L.) Leaves Inoculated with Pseudomonas syringae pv phaseolicola
TL;DR: Results demonstrate that during plant defense responses against microbial attack, several lipid-derived compounds are produced by the plant, some of which possess antimicrobial activity and conceivably are involved in plant disease resistance.
