Transcriptional levels of three different UPR-related genes at the different dilution rates. a PDF-C, and b UPP-C (presented as a comparison of transcript levels with the levels from the control GAP-C, log2 scale). P-values (t-test) were calculated for all the genes and conditions in order to determine the gene expression significance between producer clones (* significance level P ≤ 0.05)
