Research Progress of NPR in SA Signaling Pathways

doi:10.11924/j.issn.1000-6850.casb15100117

Abstract

Abstract: For a long time, salicylic acid (SA) is regarded as an endogenous signaling molecule and associated with several resistances in plants. NPR is the key factor in SA signaling pathways that can mediate the signal transduction pathways smoothly. In order to illustrate the research progress of NPR in recent years clearly, this paper introduced NPR origin and SA receptors, concluded coordinating relationship between NPR1 and its paralogs NPR3/NPR4, analyzed the mechanism of both SA signaling pathways and SA for improving resistances in plants as well. The authors concluded that even though the NPR played a significant role in SA signaling pathways, the mechanisms of plant resistance induced by SA was a sophisticated and complex network, the existing biomolecular techniques could not make function of NPR totally transparency. Moreover, transduction of various molecular was not the same in different plants or different parts of the same plant. Thus, all components with their function in this process should be further confirmed, and the integrated process also should be based on a detailed study of model plant.
