Distinct life histories impact dikaryotic genome evolution in the rust fungus Puccinia striiformis causing stripe rust in wheat

B. Schwessinger, Y.-J. Chen, R. Tien, J. K. Vogt, J. Sperschneider, R. Nagar, M. McMullan, T. Sicheritz-Ponten, C. Sorensen, M. S. Hovmoller, J. Rathjen, A. Fejer Justesen

This study compares two isolates of the wheat rust fungus Puccinia striiformis with different life histories, finding that long-term asexual evolution leads to genome expansion, transposable element accumulation, and increased heterozygosity.
