Project description:BY4741（Δyrr1）exhibited better vanillin tolerance to vanillin than that of wildtype strain. To assess transcriptional differences between these two strains. Yrr1p is a transcriptional factors which activated genes related to multidrug resistance.The transcriptome of BY4741 and BY4741（Δyrr1）under vanillin stress or vanillin free conditions were conducted,respectively
