Abstract. [...] Key Result Our study shows that NBS domains faithfully predict whole gene structure and can be divided into two major groups. Group I NBS domains contain group-specific motifs that are always linked with the TIR sequence in the N terminus. Significantly, Group I NBS domains and their associated TIR domains are widely distributed in dicot species but were not detected in cereal databases.Expand
Comparative analysis of NBS domain sequences of NBS-LRR disease resistance genes from sunflower, lettuce, and chicory.
TLDR
Recent evolution of NBS sequences within the Asteraceae family are addressed and a comparison to the Arabidopsis thaliana genome is extended, suggesting that NBS families in the Aster family are ancient, but also that gene duplication and gene loss events occur and change the composition of these gene subfamilies over time. Expand
Bioinformatics Analysis of NBS-LRR Encoding Resistance Genes in Setaria italica
TLDR
The results show the duplication of NBS-LRR genes in Setaria italica is related to their gene structure, and the largest R-gene family among plant genomes and play an important role in plant disease resistance. Expand
Full-genome analysis of resistance gene homologues in rice
TLDR
Members of phylogenetic subgroups of the class 2 NBS–LRR genes mapped to as many as ten different chromosomes indicate that they were duplicated by many independent genetic events that have occurred continuously through the expansion of the NBS-LRR superfamily and the evolution of the modern rice genome.

Analysis of TIR- and non-TIR-NBS-LRR disease resistance gene analogous in pepper: characterization, genetic variation, functional divergence and expression patterns
BackgroundPepper (Capsicum annuum L.) is one of the most important vegetable crops worldwide. However, its yield and fruit quality can be severely threatened by several pathogens. The plantExpand
Genome-wide analysis of NBS-encoding disease resistance genes in Cucumis sativus and phylogenetic study of NBS-encoding genes in Cucurbitaceae crops
TLDR
The NBS-encoding genes in Cucurbitaceae crops are shown to be ancient, and NBS -encoding gene expansions (especially the TIR family) may have occurred before the divergence of Cucorbitaceae and Arabidopsis. Expand
Isolation and analysis of resistance gene homologues in sweetpotato
TLDR
These new RGH sequences provided a resource of candidate genes and molecular markers for disease resistance research in sweetpotato and enabled the exploration of RGH diversity enables resistance gene evolutionary study and may facilitate the isolation of new and functional alleles. Expand
Evolution of the number of LRRs in plant disease resistance genes
TLDR
The evolutionary rate of the number of LRRs relative to the synonymous divergence in the NBS domain sequences is estimated by a maximum likelihood method assuming the single stepwise mutation model and the results of simulation significantly deviated from the observed data. Expand
Comparative analysis of resistance gene analogues encoding NBS-LRR domains in cotton.
TLDR
The allotetraploid genome of cotton, after separating from its diploid parents, experienced polyploidisation, natural and artificial selection, hybrid necrosis, duplication and recombination which became the reason to shed off and evolve new genes for its survival and influenced the development of genomic architecture that make it susceptible to diseases and pathogens as compared to donor parents.

Plant disease resistance genes encode members of an ancient and diverse protein family within the nucleotide‐binding superfamily
TLDR
The nucleotide binding site (NBS) is a characteristic domain of many plant resistance gene products and its wide distribution in the plant kingdom and their prevalence in the Arabidopsis and rice genomes indicate that they are ancient, diverse and common in plants. Expand

TLDR
Phylogenetic analysis suggests that a small number of NBS-LRR sequences existed among ancient Angiosperms and that these ancestral sequences diversified after the separation into distinct taxonomic families. Expand

Rapid reorganization of resistance gene homologues in cereal genomes.
TLDR
The authors' data suggest a dramatic rearrangement of R gene loci between related species and implies a different mechanism for nucleotide binding site plus leucine-rich repeat gene evolution compared with the rest of the monocot genome. Expand
Receptor-like Genes in the Major Resistance Locus of Lettuce Are Subject to Divergent Selection
TLDR
The patterns of variation support the predicted structure of LRR regions with solvent-exposed hypervariable residues that are potentially involved in binding pathogen-derived ligands. Expand
The Arabidopsis downy mildew resistance gene RPP5 shares similarity to the toll and interleukin-1 receptors with N and L6.
TLDR
The organization of repeated units within the leucine-rich repeats encoded by the wild-type R PP5 gene and an RPP5 mutant allele provides molecular evidence for the heightened capacity of this domain to evolve novel configurations and potentially new disease resistance specificities. Expand
Isolation of a superfamily of candidate disease-resistance genes in soybean based on a conserved nucleotide-binding site.
TLDR
The conserved N- or RPS2-homologous NBS sequences and their positional associations with mapped soybean-resistance genes suggest that a number of the soybean disease- Resistance genes may belong to this superfamily. Expand
Three Genes of the Arabidopsis RPP1 Complex Resistance Locus Recognize Distinct Peronospora parasitica Avirulence Determinants
TLDR
Evidence is presented suggesting that the RPP genes at this locus are subject to the same selective forces that have been demonstrated for structurally different LRR-type R genes. Expand
The I2C family from the wilt disease resistance locus I2 belongs to the nucleotide binding, leucine-rich repeat superfamily of plant resistance genes.
TLDR
Members of a new multigene family, complex I2C, were isolated by map-based cloning from the I2 F. o. Expand
The Tomato Cf-2 Disease Resistance Locus Comprises Two Functional Genes Encoding Leucine-Rich Repeat Proteins
TLDR
The C-terminus of Cf-2 carries regions of pronounced homology to the protein encoded by the unlinked Cf-9 gene, and it is suggested that this conserved region interacts with other proteins involved in activating plant defense mechanisms. Expand
The L6 gene for flax rust resistance is related to the Arabidopsis bacterial resistance gene RPS2 and the tobacco viral resistance gene N.
TLDR
The L6 rust resistance gene from flax was cloned after tagging with the maize transposable element Activator and the truncated product of L6, which lacks most of the leucine-rich C-terminal region, is similar to the truncation product that is predicted from an alternative transcript of the N gene. Expand
A Mutation within the Leucine-Rich Repeat Domain of the Arabidopsis Disease Resistance Gene RPS5 Partially Suppresses Multiple Bacterial and Downy Mildew Resistance Genes
TLDR
A mutation in the Arabidopsis RPS5 gene is isolated that indicates that the LRR region may interact with other plant proteins, and it is speculated that it may interacts with a signal transduction component shared by multiple R gene pathways. Expand
