How plants defend themselves from microbial infection is one of the most critical issues for sustainable crop production. Some TGA transcription factors belonging to bZIP superfamily can regulate disease resistance through NPR1-mediated immunity mechanisms in Arabidopsis. Here, we examined biological roles of OsTGA2 (grouped into the same subclade as Arabidopsis TGAs) in bacterial leaf blight resistance. Transcriptional level of OsTGA2 was accumulated after treatment with salicylic acid, methyl… 
OsbZIP75 positively regulates plant defense against the bacterial leaf blight pathogen Xanthomonas oryzae pv. oryzae
Results indicate that OsbZIP75/RF2a acts as a positive regulator of defense against Xoo.
OsbZIP81, A Homologue of Arabidopsis VIP1, May Positively Regulate JA Levels by Directly Targetting the Genes in JA Signaling and Metabolism Pathway in Rice
It is suggested that OsbZIP81 may positively regulate JA levels by directly targeting the genes in JA signaling and metabolism pathway in rice.
Expression Analysis of MaTGA8 Transcription Factor in Banana and Its Defence Functional Analysis by Overexpression in Arabidopsis
MaTGA8 may enhance the resistance of bananas to Foc TR4 by interacting with MaNPR11 or MaNPR4, and it is implied that the MaPR gene can be activated.

Functional analysis of rice NPR1-like genes reveals that OsNPR1/NH1 is the rice orthologue conferring disease resistance with enhanced herbivore susceptibility.
This study demonstrates that rice has evolved an SA-mediated systemic acquired resistance similar to that in Arabidopsis, and also provides a practical approach for the improvement of disease resistance without the penalty of decreased herbivore resistance in rice.
Alteration of TGA factor activity in rice results in enhanced tolerance to Xanthomonas oryzae pv. oryzae.
This study suggests that components of the (At)NPR1-mediated SAR defense response may be conserved between monocots and dicots, and suggests that rice TGA factors are involved in disease resistance responses.
Overexpression of a rice NPR1 homolog leads to constitutive activation of defense response and hypersensitivity to light.
Results indicate that NH1 may be involved in the regulation of SA in response to environmental changes, and indicates that rice has a disease-resistance pathway similar to the Arabidopsis SAR pathway.
Evidence for a disease-resistance pathway in rice similar to the NPR1-mediated signaling pathway in Arabidopsis.
This is the first demonstration that the Arabidopsis NPR1 gene can enhance disease resistance in a monocot plant and suggests that monocots and dicot plants share a conserved signal transduction pathway controlling NPR1-mediated resistance.
OsWRKY67 Plays a Positive Role in Basal and XA21-Mediated Resistance in Rice
It is suggested that OsWRKY67 positively regulates basal and XA21-mediated resistance, and is a promising candidate for genetic improvement of disease resistance in rice.
Overexpression of (At)NPR1 in rice leads to a BTH- and environment-induced lesion-mimic/cell death phenotype.
It is demonstrated that overexpression of (At)NPR1 in rice also triggers a lesion-mimic/cell death (LMD) phenotype, suggesting that (At), the central regulator of SAR in Arabidopsis, has multiple roles in plant stress responses that may affect its efficacy as a transgenic tool for engineering broad-spectrum resistance.
Enhanced disease resistance and hypersensitivity to BTH by introduction of an NH1/OsNPR1 paralog.
This study demonstrates an alternative method to employ a regulatory protein to enhance plant defence using an extra copy of NH3 driven by its own promoter (nNT-NH3) and may prove to be more practical for engineering resistance.
Rice WRKY45 plays important roles in fungal and bacterial disease resistance.
The results indicate the versatility and limitations of the application of this gene, and a universal role for WRKY45 in chemical-induced resistance, in rice.
Characterization of a salicylic acid-insensitive mutant (sai1) of Arabidopsis thaliana, identified in a selective screen utilizing the SA-inducible expression of the tms2 gene.
A genetic screen in Arabidopsis thaliana is developed that utilizes the Agrobacterium tumefaciens tms2 gene as a counter-selectable marker and suggests that the wild-type SAI1 gene acts as a positive regulator in the SA signal transduction pathway.
Identification of a novel rice bZIP-type transcription factor gene,OsbZIP1, involved in response to infection ofMagnaporthe grisea
Results indicate that the OsbZIP1 may function as a transcription factor and may play a role in salicylic acid-dependent signal transduction pathway for defense of rice against pathogens.
