The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.

Any process that increases the rate, frequency, or extent of sterigmatocystin biosynthesis. Sterigmatocystin biosynthetic processes are the chemical reactions and pathways resulting in the formation of sterigmatocystin, a carcinogenic mycotoxin produced in high yields by strains of the common molds.

Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways involving any antibiotic that contains the condensed beta-lactamthiazolidine ring system.

Any process that modulates the frequency, rate or extent of the formation of a cellular spore derived from the products of mitosis.

Any process that activates or increases the frequency, rate or extent of conidiophore development, a process that leads to the formation of a conidiophore. The conidiophore is a specialized hypha that extends aerially from the growth substrate and bears conidia, or asexual spores.

Any process that activates or increases the frequency, rate or extent of cleistothecium development, a process that leads to the formation of a cleistothecium. The cleistothecium is a closed sexual fruiting body that contains ascospores in linear asci, characteristic of some filamentous Ascomycete fungi such as members of the genera Aspergillus and Emericella.

Any process that modulates the frequency, rate or extent of gliotoxin biosynthetic process.

Any process that activates or increases the frequency, rate or extent of terrequinone A biosynthetic process.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
