Article Title: Aflatoxin Biosynthesis Is a Novel Source of Reactive Oxygen Species—A Potential Redox Signal to Initiate Resistance to Oxidative Stress?
Figure Lengend Snippet: Analysis of transcript levels in 7 h germlings. A. parasiticus SU-1, AFS10, and Δ veA were grown on YES solid media and spores were collected at 5 days. Germlings were grown from fresh spores in GMS liquid medium for 7 h, frozen in liquid nitrogen, and stored at −80 °C. RNA was extracted from germlings using grinding and sonication as described in Methods. RT-PCR was performed on total RNA treated with RNAse-free DNAse I with primers specific for each gene ( Table 3 ). PCR products were separated on a 1% agarose gel by electrophoresis. Citrate synthase, a constitutively expressed gene, was used as a positive control. gDNA, genomic DNA.
