Dear Fatia Rizki Nuraini

Genes controlling the expression of the teleomorph and anamorph evolve at different rates and that the genes controlling expression of the teleomorph are more conserved than are those controlling the expression of the anamorph

Not all Trichoderma species necessarily form a teleomorph. It depends upon the species that you are referring to. Do you know which species you have? Also, the conditions under which the teleomorph forms (for species that do have a sexual stage) can be different for each species.

Hi: Some funguse can be induce the teleomorph stage by add some of the secondary metabolite that produced by this fungus, EXP. some species of Fusarium can be induce to teleomorph stage by add DON or Fumonosin or ZEN all of these is mycotoxins produced by Fusarium Genus, and i think Trichoderma spp one of the major Genus that produce mycotoxins, you should look for the mycotoxin that related to Trichoderma and inducing sexual stage,

Dear Fatia, 

As other colleagues have mentioned, not all conidial fungi have the ability to produce a sexual stage. Furthermore, those which do produce a sexual stage, can be either homothallic or heterothallic.

Homothallic fungi can produce sexual reproductive structures in the absence of a sexually compatible strain, but mating compatible strains is required to obtain a sexual phase in heterothallic species.

In general terms, it is easier to obtain a sexual stage on poor media which resemble the conditions in which the fungus grows in nature. For example, keratinophilic Onygenales commonly produce sexual stages on keratin-rich substrates such as sterilized feathers or hairs. If you have a fungus which is associated with decaying plant material, you can try water agar with sterilized fragments of straw, carnation leaves, etc., and poor media such as oatmeal agar or potato-carrot agar.

Success!
