    ..These results indicate that NPR4 is required for basal defense against pathogens, and that it may be implicated in the cross-talk between the SA- and JA-dependent signaling pathways. ..

    ..Finally, we discuss the fundamental similarities and differences between dimerization networks within the context of bZIP factor evolution. ..

    ..The salicylic acid (SA) response factor TGA3 binds ARR2, and mutation of TGA-binding cis-elements in the Pr1 promoter abolished cytokinin- and ARR2-dependent ..

    ..Additionally, ROXY1 affects later petal morphogenesis, probably by modulating other TGA factors that might act redundantly during differentiation of second whorl organs. ..

    ..Six TGA family members were tested and shown to differentially interact with NPR1: TGA2 and TGA3 showed strong affinity for NPR1; TGA5 and TGA6 exhibited weaker affinity; and TGA1 and TGA4 displayed little or no ..

    ..Coupled with observations that the DNA binding activity of TGA factors is deregulated in npr1 plants, the results suggest that NPR1-mediated DNA binding of TGA2 is critical for activation of defense genes. ..
