Figure 4From: Phosphoribosyl pyrophosphate synthetase activity affects growth and riboflavin production in Ashbya gossypiiGrowth pattern of Δ prs2,4 and Δ prs3 mutant strains. Left, A. gossypii wild-type and prs mutant strains were grown in liquid MA2 rich medium. At the indicated time-points, mycelia were harvested and weighed. Data are represented as an average of mycelium dry-weight per volume of culture. Error bars represent SD. Right, colony photographs of the wild-type, Δprs2,4 and Δprs3 strains grown on solid MA2 rich medium during 48 hours.Back to article page
