RNA-directed RNA polymerase 1 (RdR1) mediates the resistance of . . . Microarray analysis revealed the downregulation of ADC and ODC genes, which supply substrates for synthesizing the chemical defense compound nicotine; irRdR1 lines failed to accumulate nicotine after attack We conclude that RdR1 mediates herbivore resistance, and infer that the small RNAs produced by RdR1 are probably involved in orchestrating
RNA-dependent RNA polymerase 1 in potato - Nature Cellular RNA-dependent RNA polymerases (RDRs) catalyze synthesis of double-stranded RNAs that can serve to initiate or amplify RNA silencing Arabidopsis thaliana has six RDR genes; RDRs
NgRDR1, an RNA-dependent RNA polymerase isolated from Nicotiana . . . Here, a novel RDR gene was isolated from Nicotiana glutinosa, designated as NgRDR1 The full-length cDNA of NgRDR1 encodes a 1117-amino acid protein which harbors the five conserved regions in plant RDRs, including the most remarkable motif DbDGD (b is a bulky residue)
RNA-directed RNA polymerase 1 (RdR1) mediates the resistance of . . . We conclude that RdR1 mediates herbivore resistance, and infer that the small RNAs produced by RdR1 are probably involved in orchestrating some of the rapid metabolic adjustments required for plants to survive herbivore attack in their natural habitats
Herbivory-induced changes in the small-RNA transcriptome and . . . Silencing of RNA-directed RNA polymerase 1 (RdR1) makes Nicotiana attenuata highly susceptible to insect herbivores, suggesting that defense elicitation is under the direct control of small-RNAs (smRNAs)
