Integrated transcriptomic and proteomic analysis of Arabidopsis thaliana exposed to glutathione unravels its role in plant defense

The role of glutathione (GSH) in plant defense has long been known in addition to its substantial role in stress tolerance and antioxidant signalling. In this study, molecular analysis of GSH fed Arabidopsis thaliana, exhibiting enhanced GSH content and stress tolerance potential, was performed to e...

Zusammenfassung:	The role of glutathione (GSH) in plant defense has long been known in addition to its substantial role in stress tolerance and antioxidant signalling. In this study, molecular analysis of GSH fed Arabidopsis thaliana, exhibiting enhanced GSH content and stress tolerance potential, was performed to explore the intricate position of GSH in the plant defense signaling network. Microarray data revealed the differential regulation of 653 transcripts of which 379 were upregulated and 274 were downregulated by 2-fold or more (p
