Response to nitrogen depletion differentiates winemaking strains. Differential expression analysis revealed that 14 genes at T4 had higher expression levels in the environmental (06L3FF02, 06L6FF20) and commercial (AEB Fermol Rouge, Lalvin ICV D254, and Lalvin EC1118) strains than in J940047 and S288C strains. Most of these genes are required for utilization of poor nitrogen sources, indicating differences between the strains in the response to nitrogen depletion. The panels depict the relative transcript abundance of some of these genes in each strain.
