Fitness costs of mutations affecting the systemic acquired resistance pathway in Arabidopsis thaliana.

Genetics - 1 Dec 2004

Heidel Andrew J, Clarke Joseph D, Antonovics Janis, Dong Xinnian

Abstract excerpt

This study investigated the fitness effects of four mutations (npr1, cpr1, cpr5, and cpr6) and two transgenic genotypes (NPR1-L and NPR1-H) affecting different points of the systemic acquired resistance (SAR) signaling pathway associated with pathogen defense in Arabidopsis thaliana. The npr1 mutation, which resulted in a failure to express SAR, had no effect on fitness under growth chamber conditions, but...
