TLDR
Arabidopsis, a tractable genetic system, is shown to develop resistance to a bacterial and a fungal pathogen following 2,6-dichloroisonicotinic acid (INA) treatment and three proteins that accumulated to high levels in the apoplast in response to INA treatment were purified and characterized.Abstract:
Acquired resistance is an important component of the complex disease resistance mechanism in plants, which can result from either pathogen infection or treatment with synthetic, resistance-inducing compounds In this study, Arabidopsis, a tractable genetic system, is shown to develop resistance to a bacterial and a fungal pathogen following 2,6-dichloroisonicotinic acid (INA) treatment Three proteins that accumulated to high levels in the apoplast in response to INA treatment were purified and characterized Expression of the genes corresponding to these proteins was induced by INA, pathogen infection, and salicylic acid, the latter being a putative endogenous signal for acquired resistance Arabidopsis should serve as a genetic model for studies of this type of immune response in plantsread more

Significance of Inducible Defense-related Proteins in Infected Plants
TL;DR: The evolutionary conservation of similar defense-related proteins in monocots and dicots, but also their divergent occurrence in other conditions, suggest that these proteins serve essential functions in plant life, whether in defense or not.

A technique for radiolabeling DNA restriction endonuclease fragments to high specific activity
TL;DR: A technique for conveniently radiolabeling DNA restriction endonuclease fragments to high specific activity is described, and these "oligolabeled" DNA fragments serve as efficient probes in filter hybridization experiments.
A technique for radiolabeling DNA restriction endonuclease fragments to high specific activity
TL;DR: In this article, a technique for conveniently radiolabeling DNA restriction endonuclease fragments to high specific activity is described, where DNA fragments are purified from agarose gels directly by ethanol precipitation and are then denatured and labeled with the large fragment of DNA polymerase I, using random oligonucleotides as primers.
