Genome Sequencing and Evolutionary Analysis of Marine Gut Fungus Aspergillus sp. Z5 from Ligia oceanica.

Aspergillus sp. Z5, isolated from the gut of marine isopods, produces prolific secondary metabolites with new structure and bioactivity. Here, we report the draft sequence of the approximately 33.8-Mbp genome of this strain. To the best of our knowledge, this is the first genome sequence of Aspergillus strain isolated from marine isopod Ligia oceanica. The phylogenetic analysis supported that this strain was closely related to A. versicolor, and genomic analysis revealed that Aspergillus sp. Z5 shared a high degree of colinearity with the genome of A. sydowii. Our results may facilitate studies on discovering the biosynthetic pathways of secondary metabolites and elucidating their evolution in this species.
