  • Description: <jats:title>Abstract</jats:title><jats:p>With &gt;7000 species the order of rust fungi has a disproportionately large impact on agriculture, horticulture, forestry and foreign ecosystems. The infectious spores are typically dikaryotic, a feature unique to fungi in which two haploid nuclei reside in the same cell. A key example is <jats:italic>Phakopsora pachyrhizi</jats:italic>, the causal agent of Asian soybean rust disease, one of the world’s most economically damaging agricultural diseases. Despite <jats:italic>P. pachyrhizi</jats:italic>’s impact, the exceptional size and complexity of its genome prevented generation of an accurate genome assembly. Here, we sequence three independent <jats:italic>P. pachyrhizi</jats:italic> genomes and uncover a genome up to 1.25 Gb comprising two haplotypes with a transposable element (TE) content of ~93%. We study the incursion and dominant impact of these TEs on the genome and show how they have a key impact on various processes such as host range adaptation, stress responses and genetic plasticity.</jats:p>
