NPR1 in Plant Defense: It's Not over 'til It's Turned over

Postpartum Hypertension: "It Ain't Over 'til It's Over".

Rice NRR, a negative regulator of disease resistance, interacts with Arabidopsis NPR1 and rice NH1.

Arabidopsis NPR1/NIM1 is a key regulator of systemic acquired resistance (SAR), which confers lasting broad-spectrum resistance. Over-expression of Arabidopsis NPR1 or the NPR1 homolog 1 (NH1) in rice results in enhanced resistance to the pathogen Xanthomonasoryzae pv. oryzae (Xoo), suggesting the presence of a related defense pathway in rice. We investigated this pathway in rice by identifying...

The stuck-at fault: it ain't over 'til it's over

The stuck-at fault model has existed for nearly 40 years [1]. In that time, it has been applied to a large number of interesting and challenging problems in the test area, including IC and board level fault modeling, test generation, failure isolation, and fault diagnosis. Back in the days of bipolar technologies, there often existed an isomorphism between instances of stuck-at faults and actua...

Evidence for an important role of WRKY DNA binding proteins in the regulation of NPR1 gene expression.

The Arabidopsis NPR1 gene is a positive regulator of inducible plant disease resistance. Expression of NPR1 is induced by pathogen infection or treatment with defense-inducing compounds such as salicylic acid (SA). Transgenic plants overexpressing NPR1 exhibit enhanced resistance to a broad spectrum of microbial pathogens, whereas plants underexpressing the gene are more susceptible to pathogen...

Nitric oxide-mediated maintenance of redox homeostasis contributes to NPR1-dependent plant innate immunity triggered by lipopolysaccharides.

The perception of lipopolysaccharides (LPS) by plant cells can lead to nitric oxide (NO) production and defense gene induction. However, the signaling cascades underlying these cellular responses have not yet been resolved. This work investigated the biosynthetic origin of NO and the role of NONEXPRESSOR OF PATHOGENESIS-RELATED GENES1 (NPR1) to gain insight into the mechanism involved in LPS-in...
