Strain-specific polyketide synthase genes of Aspergillus niger

► In silico analyses were performed to the pks gene inventory of two A. niger genomes. ► A. niger CBS 513.88 harbors three pks genes that are not in A. niger ATCC 1015. ► We compare the results of the in silico analyses with the in vivo situation. ► An association between the An15g07920 pks gene and ochratoxin production was found.
