“…These R genes are known to be induced only after infection by pathogens (Nair and Thomas, 2007;Peraza-Echeverria, 2008). In our study, we have found significantly higher differential expression patterns of NBS-LRR type RGAs in the root (wilt) diseaseresistant leaf samples compared to susceptible, symptomatic leaf samples for the 6 RGAs.…”

Coconut, an important crop of the tropics and subtropics, is susceptible to a variety of diseases and enhancing disease resistance has been the major goal of coconut breeding programs all over the world. Information on the presence and distribution of disease resistance (R) genes, which play a primary role in the detection of pathogens and the initiation of specific plant defenses, is scarce in coconut. In this study, RNA-Seq was used to generate the transcriptome of leaf samples of coconut root (wilt) disease-resistant cultivar Chowghat Green Dwarf. Comprehensive bioinformatics analysis identified 243 resistance gene analog (RGA) sequences, comprising 6 classes of RGAs. Domain and conserved motif predictions of clusters were performed to analyze the architectural diversity. Phylogenetic analysis of deduced amino acid sequences revealed that coconut NBS-LRR type RGAs were classified into distinct groups based on the presence of TIR or CC motifs in the N-terminal regions. Furthermore, qRT-PCR analysis validated the expression of randomly selected NBS-LRR type RGAs. The results of this study provide a sequence resource for development of RGA-tagged markers in coconut, which would aid mapping of disease-resistant candidate genes. In addition, we hope that this study will provide a genomic framework for isolation of additional RGAs in coconut via comparative genomics and also contribute to the deciphering of mode of evolution of RGAs in Arecaceae.

“…Upon pathogen perception the R-genes are induced with accumulation of higher transcript levels [33]. Our studies on the quantification of RGA RGPM 301 by qRT-PCR exhibited low level expression of transcript in the pearl millet highly resistant (IP18296) and highly susceptible (7042S) cultivars without pathogen challenge.…”

“…Among defense-related genes, those encoding nucleotide-binding site leucine-rich repeat proteins were found to be less represented in the Musa sequence (89 genes) compared to Oryza sativa (464 genes) and Vitis vinifera (459 genes) (D'Hont et al 2012). In banana an extensive isolation of resistance genes has been done (Miller et al 2008;Peraza-echeverria et al 2008). PTI (pathogen-triggered immunity)-related genes like chitin elicitor-binding protein (CeBiP) and the chitin elicitor receptor kinase (CeRK1), important components of the plant signaling pathway that recognizes chitin oligosaccharide, are expressed more in resistant cultivar than susceptible against Foc TR4 (Li et al 2012).…”
