Pathogenesis‐related proteins played a pioneering role 50 years ago in the discovery of
plant innate immunity as a set of proteins that accumulated upon pathogen challenge. The …

The members of the pathogenesis-related protein 1 (PR-1) family are among the most
abundantly produced proteins in plants on pathogen attack, and PR-1 gene expression has …

A great deal of research has been focused on the isolation, characterization, and regulation
of expression of pathogenesis-related proteins since the discovery that several of the PR …

The hypersensitive reaction to a pathogen is one of the most efficient defense mechanisms
in nature and leads to the induction of numerous plant genes encoding defense proteins …

Inducible defense-related proteins have been described in many plant species upon
infection with oomycetes, fungi, bacteria, or viruses, or insect attack. Several types of …

Pathogenesis-related (PR) proteins form a heterogeneous family of plant proteins that are
likely to be involved in defense and are inducible by pathogen attacks. One group of PRs …

Expression of pathogenesis-related protein 1a (PR-1a), a protein of unknown biochemical
function, is induced to high levels in tobacco in response to pathogen infection. The …

Pathogenesis-related proteins (PRs) are plant proteins produced in leaves in response to
infection by pathogens including viruses, viroids, fungi and bacteria. Information on the …

An overview of the evolution of knowledge on the nomenclature, classification, induction,
occurrence, functions, and role of pathogenesis-related proteins (PRs) is presented …

In incompatible host-pathogen interactions, damage caused by the pathogen remains
restricted as a result of the plant's defensive response. Most effective is the hypersensitive …
