Conserved cluster synteny between the gliotoxin cluster of A. fumigatus and the orthologous cluster of Neosartorya fischeri . The predicted gene cluster is indicated with a red bar. The left border of the Afu6g09650 cluster shows a small increase in intergenic distance while the right border shows a large change in intergenic distance. Both borders are examples of interspecies cluster synteny. Red bar indicates experimentally determined cluster boundary (Afu6g09630 - Afu6g09740). Blue bar indicates SMURF boundary prediction (Afu6g09580 - Afu6g09740) and green bar indicates the antiSMASH-predicted boundary (Afu6g09520 - Afu6g09745).
