Large-Scale Analyses of Angiosperm Nucleotide-Binding Site-Leucine-Rich Repeat Genes Reveal Three Anciently Diverged Classes with Distinct Evolutionary Patterns.
Nucleotide-binding site-leucine-rich repeat (NBS-LRR) genes make up the largest plant disease resistance gene family (R genes), with hundreds of copies occurring in individual angiosperm genomes. However, the expansion history of NBS-LRR genes during angiosperm evolution is largely unknown. By identifying more than 6,000 NBS-LRR genes in 22 representative angiosperms and reconstructing their ph...
متن کاملCutting edge: Monarch-1: a pyrin/nucleotide-binding domain/leucine-rich repeat protein that controls classical and nonclassical MHC class I genes.
Proteins containing a limited number of N-terminal motifs followed by nucleotide-binding domain and leucine-rich repeat regions are emerging as important regulators for immunity. A search of human genome scaffold databases has identified a large family of known and unknown genes, which we have recently called the CATERPILLER (caspase recruitment domain, transcription enhancer, r(purine)-binding...
متن کاملA significant fraction of 21-nucleotide small RNA originates from phased degradation of resistance genes in several perennial species.
Small RNAs (sRNAs), including microRNA (miRNA) and short-interfering RNA (siRNA), are important in the regulation of diverse biological processes. Comparative studies of sRNAs from plants have mainly focused on miRNA, even though they constitute a mere fraction of the total sRNA diversity. In this study, we report results from an in-depth analysis of the sRNA population from the conifer spruce ...
متن کاملMutational analysis of the Arabidopsis nucleotide binding site-leucine-rich repeat resistance gene RPS2.
Disease resistance proteins containing a nucleotide binding site (NBS) and a leucine-rich repeat (LRR) region compose the largest class of disease resistance proteins. These so-called NBS-LRR proteins confer resistance against a wide variety of phytopathogens. To help elucidate the mechanism by which NBS-LRR proteins recognize and transmit pathogen-derived signals, we analyzed mutant versions o...
متن کاملGenome-wide identification and tissue-specific expression analysis of nucleotide binding site-leucine rich repeat gene family in Cicer arietinum (kabuli chickpea)
The nucleotide binding site-leucine rich repeat (NBS-LRR) proteins play an important role in the defense mechanisms against pathogens. Using bioinformatics approach, we identified and annotated 104 NBS-LRR genes in chickpea. Phylogenetic analysis points to their diversification into two families namely TIR-NBS-LRR and non-TIR-NBS-LRR. Gene architecture revealed intron gain/loss events in this r...
