Gene expression change caused by CYS4 alleles


ABSTRACT: Each strain was grown overnight then diluted in fresh YPD to 10% v/v and grown for 3 hours at 30'C. Total RNA was isolated using an RNeasy mini kit, reverse transcribed, labeled with either Cy3 or Cy5, and hybridized to epoxy-coated slides with 6388, 70mer oligos (Qiagen-Operon). After an overnight hybridization, microarrays were scanned using a ScanArray Express laser scanner. Reference, a pool of total RNA from all samples, was used to contrast with each sample. Dye-swap was performed for one of the three replicates of each strain, where Cy3 instead of Cy5 was used to label the reference RNA.

The downstream consequences of a single quantitative trait polymorphism can provide important insight into the molecular basis of a trait. However, the molecular consequences of a polymorphism may be complex and only a subset of these may influence the trait of interest. In natural isolates of Saccharomyces cerevisiae, a nonsynonymous polymorphism in cystathione beta-synthase (CYS4) causes a deficiency in both cysteine and glutathione that results in rust-colored colonies and drug-dependent grow  ...[more]
