Abstract Transcription activator-like effectors (TALEs) are proteins produced by plant pathogenic Xanthomonas spp. TALEs exhibit a conserved structure and have the ability to directly bind promoter region of host target genes where they activate transcription. in oryzae pv. ( Xoo ), causal agent bacterial blight (BB) rice, play important roles triggering resistance (ETI) susceptibility (ETS) fo...

To identify novel virulence associated genes in Xanthomonas oryzae pv. oryzae (Xoo), a Xoo isolate (XooIR42), obtained from north of Iran, was selected to generate a mini-Tn5 transposon mutation library. One mutant (XooM176) that indicated reduced virulence on rice plants, while grew similar to wild type was selected. This mutant had an insertion in a coding region with 96% amino acid identity ...
