“…Alternatively, thiamine may be directly involved in transcriptional regulation of pigment formation. This possibility is consistent with the findings in Schizosaccharomyces pombe and other fungi, in which thiamine controls its synthesis, phosphorylation, and transport, as well as developmental cellular processes (e.g., mating and zygote formation) (Fankhauser and Schweingruber, 1994;Fankhauser et al, 1995;Garraway and Evans, 1984;Schweingruber et al, 1991;Schweingruber and Edenharter, 1990;Tang et al, 1994). It is also interesting to note that compared to the remarkable, narrow-range repression of nmt1 transcription by thiamine in S. pombe (Maundrell, 1990), our results demonstrate that its phenotypic effect on pigmentation of U. hordei is observed at 10-fold lower levels.…”

“…This difference could reflect that efficient thiamine uptake requires expression of the thiamine transporter in low-thiamine media, whereas the thiamine biosynthetic genes can be fully repressed under these conditions. In S. pombe, the thiamine biosynthetic gene nmt1 ϩ is under control of two related transcription factors, Thi1 and Thi5, both of which are necessary for its full expression in media lacking thiamine (62)(63)(64). It is known that Thi1 is necessary for the expression of bsu1 ϩ (55) but the influence of Thi1 and Thi5 on thi9 ϩ awaits experimental clarification.…”
