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.

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

TL;DR: SAR, likewise, is a generally occurring phenomenon, that engenders an enhancement of the defensive capacity of plants in response to necrotizing infections, associated with the development of systemic acquired resistance (SAR) against further infection by fungi, bacteria and viruses.

TL;DR: Analysis of the Arabidopsis mutant npr1 revealed that the antagonistic effect of SA on JA signaling requires the regulatory protein NPR1, indicating that cross-talk between SA and JA is modulated through a novel function of NPR1 in the cytosol.

TL;DR: This study shows that SA, JA, and ET play a primary role in the orchestration of the plant's defense response, but other regulatory mechanisms, such as pathway cross-talk or additional attacker-induced signals, eventually shape the highly complex attacker-specific defense response.
