fungal response to plant hormones

[Nora Plesofsky-Vig]

This is a question that was asked of me by a colleague who studies  
plants. Does anyone have experience with a mycelial fungus or yeast  
responding to the plant hormones gibberellic acid and/or indole  
acetic acid (auxin)? This question is being asked with the intention  
of possibly using a fungus to study hormonal effects. Any literature  
references would also be appreciated.

Thanks for answering.
