  abstract = {{A}frican strains of {X}anthomonas oryzae pv. oryzae contain fewer {TAL} effectors than {A}sian strains, and their contribution to pathogenicity is unknown. {S}ystematic mutagenesis of tal genes was used to decipher the contribution of each of the eight {TAL} effector paralogs to pathogenicity of {A}frican {X}. oryzae pv. oryzae {BAI}3. {A} strain mutated in tal{C} was severely affected in the production of disease symptoms. {A}nalysis of growth in planta upon leaf-clip inoculation showed that mutant bacteria multiplied only at the site of inoculation at the apex of the leaf, suggesting a requirement for tal{C} during colonization of vascular tissues. {S}uch tissue-specific effect of a tal mutant is a novel phenotype, which has not yet been characterized in other xanthomonads. {M}icroarray experiments comparing the host response of rice leaves challenged with {BAI}3({R}) vs. {BAI}3({R}){D}elta tal{C} were performed to identify genes targeted by {T}al{C}. {A} total of 120 upregulated and 21 downregulated genes were identified, among them {O}s11{N}3, which is a member of the {M}t{N}3/saliva family. {B}ased on semiquantitative reverse transcription-polymerase chain reaction and beta-glucuronidase reporter assays, we show that {O}s11{N}3 is directly upregulated by {T}al{C} and identify a {T}al{C} {DNA} target box within the {O}s11{N}3 upstream sequence.},
