Global Identification of Noncoding RNAs in S. cerevisiae

ABSTRACT: Genome-wide detection of novel non-coding RNAs in S. cerevisiae by modulating an RNase P pathway through the depletion of a component RPP1. Nearly 400,000 36-mer oligonucleotide probes, tiling the entire yeast genome including the mitochondrial chromosome with an average gap of 10 bases between two consecutive probes, were synthesized on glass slides using a mask-less array synthesizer. RNA samples for hybridizing to the arrays were extracted from a conditional lethal allele of S. cerevisiae created by placing the RPP1 gene under control of GAL10 promoter. It allowed the expression of RPP1 in galactose-containing culture medium but suppressed its expression in glucose-containing medium. A wild-type isogenic strain was used as a control. Both strains were initially grown in galactose-contai
