Interpretive Summary: Rust fungi have caused destructive plant epidemics, become more aggressive with new virulence and rapidly adapted to new environments, and are continually threatening to agriculture. With the rapid advancement of genome sequencing technologies and data analysis tools, genomics research on many of the devastating rust fungi have generated unprecedented insights into various aspects of rust biology. In this review, we first present a brief summary of the main findings in genomics of rust fungi related to variations in genome size and gene composition between and within species. Then we show how genomics of rust fungi promoted our understanding of its virulence and population dynamics. Albeit the great progress, many questions are still to be answered. Therefore, we introduce several perspectives with emphases on genome evolution and host adaptation of rust fungi. We believe that the comparative genomics and population genomics of rust fungi will provide further understanding of the rapid evolution of virulence and will make contribution to monitoring population dynamics for the disease management.

Technical Abstract: Rust fungi in Pucciniales have caused destructive plant epidemics, become more aggressive with new virulence and rapidly adapted to new environments, and are continually threatening to agriculture. With the rapid advancement of genome sequencing technologies and data analysis tools, genomics research on many of the devastating rust fungi have generated unprecedented insights into various aspects of rust biology. In this review, we first present a brief summary of the main findings in genomics of rust fungi related to variations in genome size and gene composition between and within species. Then we show how genomics of rust fungi promoted our understanding of its virulence and population dynamics. Albeit the great progress, many questions are still to be answered. Therefore, we introduce several perspectives with emphases on genome evolution and host adaptation of rust fungi. We believe that the comparative genomics and population genomics of rust fungi will provide further understanding of the rapid evolution of virulence and will make contribution to monitoring population dynamics for the disease management.
