Project description:1. Supplementation of cultures of Eremothecium ashbyii with ribitol leads to a twofold increase in riboflavin formation compared with unsupplemented cultures or those supplemented with ribose or ribulose phosphate. Addition of unlabelled ribitol decreases the incorporation of [1-(14)C]ribose into riboflavin, indicating that free ribitol is preferred to ribose for incorporation into riboflavin. 2. The enzymes ribitol kinase, d-ribose reductase, d-ribose 5'-phosphatase and GMP nucleosidase were demonstrated in the cell-free extracts. Ribitol induces the formation of ribitol kinase. The enzyme is activated in vitro by the flavinogenic purines, guanine and xanthine. d-Ribose reductase shows a specific requirement for NADPH and forms free ribitol from ribose. 3. The activities of ribitol kinase, ribose 5'-phosphatase and GMP nucleosidase reach their maximal values before riboflavin formation reaches a maximum. 4. [U-(14)C]GMP is taken up intact by the culture of E. ashbyii and is incorporated into riboflavin as well as into a blue fluorescent compound. The radioactivity from this compound is incorporated into riboflavin by the cell-free extract of E. ashbyii.

Project description:The genus Eremothecium belongs to the Saccharomyces complex of pre-whole-genome duplication (WGD) yeasts and contains both dimorphic and filamentous species. We established the 9.1-Mb draft genome of Eremothecium coryli, which encodes 4,682 genes, 186 tRNA genes, and harbors several Ty3 transposons as well as more than 60 remnants of transposition events (LTRs). The initial de novo assembly resulted in 19 scaffolds, which were assembled based on synteny to other Eremothecium genomes into six chromosomes. Interestingly, we identified eight E. coryli loci that bear centromeres in the closely related species E. cymbalariae. Two of these E. coryli loci, CEN1 and CEN8, however, lack conserved DNA elements and did not convey centromere function in a plasmid stability assay. Correspondingly, using a comparative genomics approach we identified two telomere-to-telomere fusion events in E. coryli as the cause of chromosome number reduction from eight to six chromosomes. Finally, with the genome sequences of E. coryli, E. cymbalariae, and Ashbya gossypii a reconstruction of three complete chromosomes of an Eremothecium ancestor revealed that E. coryli is more syntenic to this ancestor than the other Eremothecium species.
