Introduction
One of the main defense mechanisms is resistance (R) gene-mediated disease resistance. The majority of R genes characterized encode proteins that have a central nucleotide-binding region (NB) plus a C- terminal leucine-rich repeat (LRR).The NB-LRR proteins recognize the corresponding avirulence (Avr) effectors produced by the pathogen and activate defense responses. In most cases, these defense responses are accompanied by a hypersensitivity response (HR) in the infected cells, triggering the rapid production of reactive oxygen species (ROS).These defense responses are also associated with accumulation of salicylic acid (SA), which functions in the induction of numerous pathogenesis-related (PR) genes, and the establishment of systemic acquired resistance (SAR).SA is required in R gene-mediated defense signaling pathways. It is assumed that R proteins are present in an auto-inhibited state and are unable to activate defense responses in the absence of pathogens.
Function
NLS1 displays spontaneous lesions, specifically on leaf sheaths, with a developmental pattern. nls1-1D plants also exhibited constitutively activated defense responses, including extensive cell death, excess hydrogen peroxide and salicylic acid (SA) accumulation, up-regulated expressions of pathogenesis-related genes, and enhanced resistance to bacterial pathogens.
Expression
NLS1 encodes a typical CC-NB-LRR-type protein in rice and causes a S367N substitution in the non-conserved region close to the GLPL motif of the NB domain

Summary
In this study, we characterized the semi-dominant mutant nls1-1D (necrotic leaf sheath 1) of rice, which displays spontaneous lesions, specifically on leaf sheaths, with a developmental pattern. nls1-1D plants also exhibited constitutively activated defense responses, including extensive cell death, excess hydrogen peroxide and salicylic acid (SA) accumulation, up-regulated expressions of pathogenesis-related genes, and enhanced resistance to bacterial pathogens. Map-based cloning revealed that NLS1 encodes a typical CC-NB-LRR-type protein in rice. The nls1-1D mutation causes a S367N substitution in the non-conserved region close to the GLPL motif of the NB domain. An adjacent S366T substitution was found in another semi-dominant mutant, nls1-2D, which exhibited the same phenotypes as nls1-1D. Combined analyses of wild-type plants transformed with the mutant NLS1 gene (nls1-1D), NLS1 RNAi and over-expression transgenic lines showed that nls1-2D is allelic to nls1-1D, and both mutations may cause constitutive auto-activation of the NLS1 R protein. Further real-time PCR analysis revealed that NLS1 is expressed constitutively in an age-dependent manner. In addition, because the morphology and constitutive defense responses of nls1-1D were not suppressed by blocking SA or NPR1 transcript accumulation, we suggest that NLS1 mediates both SA and NPR1-independent defense signaling pathways in rice.
