AtNHR2A and AtNHR2B: Two Players of the Plant Secretory Pathway Functioning in Biotic Stress Responses.

Phytopathology - 1 Apr 2026

Abstract excerpt

AtNHR2A (Arabidopsis thaliana nonhost resistance 2A) and AtNHR2B (nonhost resistance 2B) are immunity-associated proteins required for resistance to the nonadapted pathogen Pseudomonas syringae pv. tabaci (Pstab) that is unable to cause disease in wild-type Col-0 plants. The enhanced susceptibility of the Atnhr2b Atnhr2a double mutant suggests that these proteins function synergistically in plant defense. Both...
