Physiological and Molecular Plant Pathology 

TL;DR: SAR, likewise, is a generally occurring phenomenon, that engenders an enhancement of the defensive capacity of plants in response to necrotizing infections, associated with the development of systemic acquired resistance (SAR) against further infection by fungi, bacteria and viruses.

TL;DR: Two major models describing the origin of ROS in the oxidative burst are presented, namely: the NADPH oxidase system analogous to that of mammalian phagocytotic cells, and the pH-dependent generation of hydrogen peroxide by exocellular peroxidases.

TL;DR: The results suggest that the plant defense enzymes could be stimulated in cucumber roots which have been colonized by non-pathogenic rhizobacteria or in a compatible interaction between cucumber and P. aphanidermatum.

TL;DR: It is proposed that these cells can, first, by decompartmentation, rapid oxidation of their phenolic content, and the ensuing lignification and suberization of cells, and cell death, seal off infections or injuries at the immediate site of cellular penetration and if this defence should fail and the stress persist, these same processes promote the prolonged build-up of IAA and ethylene that cause a further metabolic cascade in outlying cells to produce a peridermal defence in depth.

TL;DR: In this article, random amplified polymorphic DNA assays were used to identify amplification products characteristic of either Fusarium culmorum or fusarium graminearum and selected fragments were cloned, sequenced and primer pairs were developed which permitted specific detection of F. graminearlyum using conventional PCR.
