“…During the photosynthetic process, light energy is changed to chemical energy using Chl in chloroplast and stored as sugar bond 22 . In this study, we show that F m values increased in Zn-treated and NACtreated plants compared to Zn-untreated or NACuntreated plants, implying that GSH induced by NAC treatment might cause a higher efficiency in energy transfer from PSII to PSI 11 and might control physiological parameters (Fig. 2).…”

“…In particular, GSH scavenges reactive oxygen species and detoxifies toxic chemicals 19,20 . Despite the importance of GSH in ROS signalling, few studies have found that GSH contents control plant growth and development 11 . Glutathione level is regulated by ascorbate-GSH cycle (Halliwell and Asada pathway), thus it is expected that alterations of GSH contents may affect plant metabolic function and plant growth.…”

“…Glutathione level is regulated by ascorbate-GSH cycle (Halliwell and Asada pathway), thus it is expected that alterations of GSH contents may affect plant metabolic function and plant growth. In Arabidopsis, a loss-offunction mutation of light harvesting antenna (ch1-1 mutation) impairs GSH content in cells of leaf and shows depressed growth and development 11 . The current study however reveals that NAC application increases corn yield by modulating Zn-induced physiological parameters.…”

“…Eight treatments with five replicates were arranged according to a completely randomized design. Four Zn concentrations (0, 0.2, 1.5, and 3.0 ppm of Zn) were applied, with or without NAC (0 and 100 µM), which increased GSH content in the different cells of leaf 11 .…”

Glutathione (GSH), a non-protein molecule containing thiol groups affects plant growth and development. In this study, the effects of GSH on Zn-induced corn production were evaluated. Different Zn concentrations (0, 0.2, 1.5, and 3.0 ppm of Zn), with or without 100 µm of N-acetylcysteine (NAC), were arranged as a completely randomized design with 5 replications. Results show that neither NAC nor Zn affects plant height or leaf numbers. The treatment with NAC did not increase Zn-induced relative water content in leaves while enhancing Zn-induced photosynthesis rate (P n ) and photosynthetically active radiation. Zn-induced chlorophyll (Chl) contents and Chl fluorescence (F m ) were increased by the NAC treatment. In addition, corn showed an improve yield and cob length in NAC-treated plants in the presence of Zn. Taken together, this study suggests that NAC might improve some physiological functions to enhance Zn-induced corn production.
