The transcripts corresponding to two A. rabiei genes previously identified in response to oxidative stress (Ar125, Ar126) and the polyketide synthase pks2 were also found to be over-expressed during infection, but not pks1 and cps1 (Tenhaken et al., 1997; White and Chen, 2007; Akamatsu et al., 2010; Singh et al., 2012). The gene discussed is CPS1; the disease is infection.
