Secreted immune proteases "Required for Cladosporium resistance-3" (Rcr3) and "Phytophthora-inhibited protease-1" (Pip1) of tomato (Solanum lycopersicum) are both inhibited by Avirulence-2 (Avr2) from the fungal plant pathogen Cladosporium fulvum. However, only Rcr3 acts as a decoy co-receptor that detects Avr2 in the presence of the Cf-2 immune receptor. Here, we identified crucial residues in tomato Rcr3 that are required for Cf-2-mediated signaling and bioengineered various proteases to trigger Avr2/Cf-2-dependent immunity.

The Avr2-Rcr3 complex is recognized by receptor-like protein Cf-2, triggering hypersensitive cell death (HR) and disease resistance. Avr2 also targets Rcr3 paralog Pip1, which is not required for Avr2 recognition but contributes to basal resistance.

Materials And Methods: Nineteen young males participated in the study (age, 23 ± 3 years; height, 178 ± 6 cm; weight, 78 ± 15 kg). Participants completed a maximum oxygen uptake ([Formula: see text]) test and a gaming session, including AVGs ("Reflex Ridge," "River Rush," and "Boxing" for the Microsoft [Redmond, WA] Kinect™) and SVGs ("FIFA 14" [Electronic Arts, Burnaby, BC, Canada] and "Call of Duty" [Activision, Santa Monica, CA]).
