Abstract

Importance: is the causal agent of the destructive blast disease, which caused massive loss of yield annually worldwide. The fungus diverged into distinct clades during adaptation toward the two rice subspecies, Xian/ and Geng/. Although the role of TEs in the adaptive evolution was well established, mechanisms underlying how TEs promote the population divergence of remain largely unknown. In this study, we reported that TEs shape the population divergence of by differentially regulating gene expression between Xian/-infecting and Geng/-infecting populations. Our results revealed a TE insertion-mediated gene expression adaption that led to the divergence of population infecting different rice subspecies.
