  abstract = {{B}acterial leaf streak ({BLS}) caused by {X}anthomonas oryzae pv. oryzicola was first reported in {A}frica in the 1980s. {R}ecently, a substantial reemergence of this disease was observed in {W}est {A}frica. {S}amples were collected at various sites in five and three different rice-growing regions of {B}urkina {F}aso and {M}ali, respectively. {S}ixty-seven {X}. oryzae pv. oryzicola strains were isolated from cultivated and wild rice varieties and from weeds showing {BLS} symptoms. {X}. oryzae pv. oryzicola strains were evaluated for virulence on rice and showed high variation in lesion length on a susceptible cultivar. {X}. oryzae pv. oryzicola strains were further characterized by multilocus sequence analysis ({MLSA}) using six housekeeping genes. {I}nferred dendrograms clearly indicated different groups among {X}. oryzae pv. oryzicola strains. {R}estriction fragment length polymorphism analysis using the transcriptional activator like effector avr{X}a7 as probe resulted in the identification of 18 haplotypes. {P}olymerase chain reaction-based analyses of two conserved type {III} effector ({T}3{E}) genes (xop{AJ} and xop{W}) differentiated the strains into distinct groups, with xop{AJ} not detected in most {A}frican {X}. oryzae pv. oryzicola strains. {X}op{AJ} functionality was confirmed by leaf infiltration on '{K}itaake' rice {R}xo1 lines. {S}equence analysis of xop{W} revealed four groups among {X}. oryzae pv. oryzicola strains. {D}istribution of 43 {T}3{E} genes shows variation in a subset of {X}. oryzae pv. oryzicola strains. {T}ogether, our results show that {A}frican {X}. oryzae pv. oryzicola strains are diverse and rapidly evolving, with a group endemic to {A}frica and another one that may have evolved from an {A}sian strain.},
