Transcriptomic and Functional Studies of the RGS Protein Rax1 in <i>Aspergillus fumigatus</i>

In the comparative transcriptomic studies of wild type (WT) and <i>rax1</i> null mutant strains, we obtained an average of 22,222,727 reads of 101 bp per sample and found that 183 genes showed greater than 2.0-fold differential expression, where 92 and 91 genes were up-and down-regulated...
