Phenolic-storing cells : keys to programmed cell death and periderm formation in wilt disease resistance and in general defence responses in plants?
TLDR
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.About:

Anatomical and chemical defenses of conifer bark against bark beetles and other pests.
TL;DR: This review focuses on bark defenses, a front line against organisms trying to reach the nutrient-rich phloem, and questions about their coevolution with bark beetles are discussed.

The oxidative burst in plant disease resistance
TL;DR: Emerging data indicate that the oxidative burst reflects activation of a membrane-bound NADPH oxidase closely resembling that operating in activated neutrophils, which underlies the expression of disease-resistance mechanisms.

Systemic resistance induced by rhizosphere bacteria
TL;DR: Rhizobacteria-mediated induced systemic resistance (ISR) is effective under field conditions and offers a natural mechanism for biological control of plant disease.

Phenolic Compounds and Their Role in Disease Resistance
TL;DR: This review addresses the problem of response localization and localization of phenolics relative to the sequential development of stages of disease that lead ultimately to resistance expression and initial demonstrations that phenols are significant components of the host.
