Fig. 1From: Promoters from the itaconate cluster of Ustilago maydis are induced by nitrogen depletionClustered itaconate genes in U. maydis including trans-aconitate decarboxylase (tad1), a major facilitator superfamily transporter (itp1), an aconitate–Δ–isomerase (adi1), a mitochondrial tricarboxylate transporter (mtt1), and a transcriptional regulator (ria1) [17].
