A. nidulans purine transporters mutations

[Microbiologist]

I am working on the effects of the UV radiation in a strain of Aspergillus
nidulans in which has all 3 purine transporters (UpaA, UpaC, AzgA) have
total loss of function.

Are there any papers on this subject or is somebody else working on this
subject who wishes to discuss these things with me?

Please, contact me at nsophos at hotmail.com

Thank you!
