Plants that have been genetically engineered to produce additional amounts of NPR1's protein show extra resistance to attack by both a fungus and a bacterium, say researchers at Duke University in Durham, N.C.
NPR1, a key regulator, seems to marshal an army of other genes to fight pathogens.
The dream of a good-health gene glows particularly bright because scientists have already found genes similar to mustard NPR1 in major commercial crops, including corn, wheat, canola, and tobacco.
En la expresion de PR-1 por SA, existen dos posibles vias de senalizacion, una dependiente y otra independiente de NPR1 (Non-expresser of PR-1) (Clarke et al., 2000).
De forma similar, PAD4 y EDS1 son requeridos para la produccion de SA, y la expresion de estos es incrementada por SA y por otra parte, NPR1 controla los niveles de SA, pero responde a niveles altos de SA (Desveaux et al., 2004).
En los mecanismos de comunicacion cruzada se han identificado proteinas como la NPR1 y la glutaredoxina, que presentan un efecto antagonico al SA en la expresion de genes de respuesta a JA (Spoel et al., 2003); el factor de transcripcion WRKY70 activa genes de respuesta de SA y reprime genes inductores de JA, actuando como un interruptor molecular en estas dos vias (Li et al., 2004), y los factores de transcripcion ERF1 y MYC2 actuan como integradores de senales de las vias JA y ET y activan diferencialmente genes de defensa dependientes de JA (Lorenzo et al., 2003).
Variable coefficients for industrial NPR1 proximity variables were extremely sensitive to monitor selection.
This resistance required salicylate, but was independent of NPR1. Another study showed that a mutation in a putative Arabidopsis MAPKKK resulted in a mutant (edr1, improved disease resistance) with increased resistance to powdery mildew and Pseudomonas syringae without any phenotypic changes (Frye et al., 2001).

High-level expression of the Arabidopsis NPR1 gene, a positive regulator of the systemic acquired resistance signaling pathway, conferred enhanced resistance to a bacterial and fungal pathogen of Arabidopsis (Cao et al., 1998).
Uno de los genes candidatos para controlar la expresi on de algunos genes PR es el NPR1 en Arabidopsis.
The Arabidopsis NPR1 gene that controls systemic acquired resistance encodes a novel protein containing ankyrin repeats.
