Transcriptional responses to glutaminyl tRNA synthetase Gln4p depletion in Saccharomyces cerevisiae

A tet-off strain of Saccharomyces cerevisiae was constructed in which the GLN4 glutamine tRNA synthetase gene was placed under control of a doxycycline-regulated promoter. The transcriptional responses to Gln4p tRNA synthetase depletion were assessed by growth of the strain in the presence, or absence, of doxycycline (1 µg/ml). A control, wild-type strain was similarly treated with doxycycline or left untreated as a reference. Each strain/condition RNA isolation was performed using triplicate independent biological samples A, B and C. Overall design: Total RNA samples were extracted from control, or GLN4 tet-off yeast growing in the presence or absence of doxycycline, and the RNA subjected to Illumina RNA-seq.
