Figure 3: txtA and txtC gene expression and thaxtomin A production in S. scabies over time. txtA and txtC gene expression was monitored in S. scabies every 24 h over the course of 10 days using quantitative RT-PCR assays. Concurrently, thaxtomin A was quantifi ed in the growth medium using highperformance liquid chromatography. All data are presented as mean ± standard error (n = 4).
