|a The role of glutathione (GSH) in plant defense is an established fact. However, the association of GSH with other established signaling molecules within the defense signaling network remains to be evaluated. Previously we have shown that GSH is involved in defense signaling network likely through NPR1-dependent salicylic acid (SA)-mediated pathway. In this study, to gain further insight, we developed chloroplast-targeted gamma-glutamylcysteine synthetase (γ-ECS) overexpressed transgenic Nicotiana tabacum (NtGp line) and constructed a forward subtracted cDNA (suppression subtractive hybridization (SSH)) library using NtGp line as a tester. Interestingly, in addition to SA-related transcripts like pathogenesis-related protein 1a (PR1a) and SAR8.2 m/2l, 1-aminocyclopropane-1-carboxylate oxidase (ACC oxidase), a key enzyme of ethylene (ET) biosynthesis, was identified in the SSH library. Besides, transcription factors like WRKY transcription factor 3 (WRKY3), WRKY1 and ethylene responsive factor 4 (ERF4), associated with SA and ET respectively, were also identified thus suggesting an interplay of GSH with ET and SA. Furthermore, proteomic profiling of NtGp line, performed by employing two-dimensional gel electrophoresis (2-DE), corroborated with the transcriptomic profile and several defense-related proteins like serine/threonine protein kinase, and heat shock 70 protein (HSP70) were identified with increased accumulation. Fascinatingly, induction of 1-aminocyclopropane-1-carboxylate synthase (ACC synthase) was also noted thus demonstrating the active involvement of GSH with ET. Protein gel blot analysis confirmed the enhanced accumulation of ACC oxidase in NtGp line. Together, our data revealed that GSH is involved in the synergistic multiple steps crosstalk through ET as well as SA to combat environmental stress
