From: l-Methionine repressible promoters for tuneable gene expression in Trichoderma reesei
Transcriptional profile of selected l-methionine repressible genes. Transcript levels of the six most highly regulated genes of the transcriptome analysis were tested following the addition of different amounts of l-methionine (0–1 mM) to a 48 h old wheat straw culture of T. reesei QM9414. The expression was correlated to that of a sample taken just before the addition of l-methionine and normalized on tef1.
