DESCRIPTION:Xanthomonas translucens pv. undulosa (Xtu) is the causal agent
  of wheat bacterial leaf streak (BLS)\, which has become an important dise
 ase in the Midwestern United States and elsewhere. We recently discovered 
 that Xtu strains differ in their avirulence on the Aegilops tauschii acces
 sion TA10105. A diverse set of Xtu strains was phenotyped on this accessio
 n\, and representative virulent and avirulent isolates were selected for w
 hole-genome sequencing. Comparative genomic analysis identified a single t
 ype III effector gene present exclusively in avirulent isolates. Targeted 
 disruption of this gene in an avirulent strain resulted in a susceptible r
 eaction on TA10105\, confirming its role in avirulence. To identify the co
 rresponding resistance gene\, an F₂ population derived from a cross betw
 een TA10105 and a susceptible A. tauschii line was developed and used for 
 genetic mapping. The resistance locus was mapped to chromosome 5D. (...)
