Identification of the polyketide synthase gene responsible for the synthesis of tanzawaic acids in Penicillium steckii IBWF104-06.

Microorganisms have been used as biological control agents (BCAs) in agriculture for a long time, but their importance has increased dramatically over the last few years. The Penicillium steckii IBWF104-06 strain has presented strong BCA activity in greenhouse experiments performed against phytopathogenic fungi and oomycetes. P.
