简介
- Salicylic acid (SA) is an important signaling molecule of the plant immune system.
- In Arabidopsis thaliana, SA biosynthesis is indirectly modulated by the closely related transcription factors TGACG‐BINDING FACTOR 1 and 4 (TGA1 and TGA4, respectively). They activate expression of SYSTEMIC ACQUIRED RESISTANCE DEFICIENT1, the gene product of which regulates the key SA biosynthesis gene ISOCHORISMATE SYNTHASE 1.
- Since TGA1 interacts with the SA receptor NONEXPRESSOR OF PATHOGENESIS‐RELATED GENES 1 (NPR1) in a redox‐dependent manner and since the redox state of TGA1 is altered in SA‐treated plants, TGA1 was assumed to play a role in the NPR1‐dependent signaling cascade. Here, we identified 193 out of 2090 SA‐induced genes that require TGA1/TGA4 for maximal expression after SA treatment. One robustly TGA1/TGA4‐dependent gene encodes for the SA …
