TL;DR: In this article, a yeast protein interaction screen with tobacco TGA2.2 as bait and an Arabidopsis thaliana cDNA prey library was performed and led to the identification of a member of the glutaredoxin family (GRX480, encoded by At1g28480).

TL;DR: A cauliflower mosaic virus (CaMV) 35S promoter derivative, which is tightly repressed by the Tn 10 encoded Tet repressor in a transient expression system as well as in transgenic plants has been constructed and provides a unique tool for regeneratingtransgenic plants carrying a repressed transgene.

TL;DR: The identification of Arabidopsis thaliana SCARECROW-like 14 (SCL14), a member of the GRAS family of regulatory proteins, as a TGA-interacting protein that is required for the activation of T GA-dependent but NPR1-independent SA- and 2,4-D–inducible promoters is reported.

TL;DR: In this article, the same transcription factors are essential for the activation of jasmonic acid and ethylene (ET)-dependent defense mechanisms that counteract necrotrophic pathogens: the tga256 triple mutant is impaired in JA/ET-induced PDF1.2 and b-CHI expression, which correlates with a higher susceptibility against the necrotroph Botrytis cinerea.

TL;DR: It is shown that NIMIN1 and NPR1 can be copurified from plant extracts, providing biochemical evidence for their interaction and strongly suggest that NimIN1 negatively regulates distinct functions of NPR1, providing a mechanism to modulate specific features of SAR.
