  abstract = {{T}he evolution of new variants of plant pathogens is one of the biggest challenges to controlling and managing plant diseases. {O}f the forces driving these evolutionary processes, global migration events are particularly important for widely distributed diseases such as potato late blight, caused by the oomycete {P}hytophthora infestans. {H}owever, little is known about its migration routes outside {N}orth {A}merica and {E}urope. {T}his work used genotypic data from population studies to elucidate the migration history originating the {C}olombian {P}. infestans population. {F}or this purpose, a dataset of 1,706 {P}. infestans genotypes was recollected, representing {N}orth and {S}outh {A}merica, {E}urope, and {A}sia. {D}escriptive analysis and historical records from {N}orth {A}merica and {E}urope were used to propose three global migration hypotheses, differing on the origin of the disease ({M}exico or {P}eru) and the hypothesis that it returned to {S}outh {A}merica from {E}urope. {T}hese scenarios were tested using approximate {B}ayesian computation. {A}ccording to this analysis, the most probable scenario (posterior probability = 0.631) was the one proposing a {P}eruvian origin for {P}. infestans, an initial migration toward {C}olombia and {M}exico, and a later event from {M}exico to the {U}nited {S}tates and then to {E}urope and {A}sia, with no return to northern {S}outh {A}merica. {I}n {C}olombia, the scenario considering a single migration from {P}eru and posterior migrations within {C}olombia was the most probable, with a posterior probability of 0.640. {T}he obtained results support the hypothesis of a {P}eruvian origin for {P}. infestans followed by rare colonization events worldwide.},
