On the other hand, the possibility that gamma-glutamyl cycling be implicated in the response to oxidative stress might be inferred by some previous reports (Masi et al., To better investigate the relationship between oxidizing stress conditions and GGT-driven glutathione degradation, apoplastic fluid proteins were extracted from leaves of the ggt1 mutant following ultraviolet B (UV-B) treatment (Trentin et al., ggt1 silencing, the mutation itself resulted in reduced expression of a number of plasma-membrane associated genes (cys-rich, leucine-rich secretory proteins) involved in signaling and assigned to response to stimulus as per the gene ontology
