Plant and animal PR1 family members inhibit programmed cell death and suppress bacterial pathogens in plant tissues.

ABSTRACT: A role for programmed cell death (PCD) has been established as the basis for plant-microbe interactions. A functional plant-based cDNA library screen identified possible anti-PCD genes, including one member of the PR1 family, designated P14a, from tomato. Members of the PR1 family have been subject to extensive research in view of their possible role in resistance against pathogens. The PR1 family is represented in every plant species studied to date and homologues have been found in animals, fungi and insects. However, the biological function of the PR1 protein from plants has remained elusive in spite of extensive research regarding a role in the response of plants to disease. Constitutive expression of P14a in transgenic tomato roots protected the roots against PCD triggered by Fumonisi
