Time course of expression of all ubiquitin-coding genes in the UBI4 repeat variants during heat shock. a Time series of UBI4 expression in the repeat variants (carrying a UBI4 gene encoding either 0, 1, 2, 3, or 5 ubiquitin units) during a sustained heat shock (HS) at 44 °C. UBI4 transcripts were measured by real-time quantitative PCR (RT-qPCR) using primers that specifically anneal to one ubiquitin moiety allowing the measurement of the transcripts from each UBI4 repeat variant rather than the total number of ubiquitin moieties per transcript. Inset shows the expression of UBI4 at time point 0 (before HS) in the repeat variants. b Time series of UBI1, UBI2, and UBI3 expression in the UBI4 repeat variants during the HS at 44 °C. Primers specific for the ribosomal protein-coding region were used to distinguish between the different genes. a, b Data are mean of 2 biological replicates (and 2 technical replicates per sample) ± SD
