Saccharomyces cerevisiae grown in nitrogen depletion with MTP priming

ABSTRACT: Multi-targeting priming (MTP) for genome-wide gene expression assays provides selective targeting of multiple sequences and counter-selection against undesirable sequences. We demonstrated superior performance of two MTPs compared to oligo-dT microarray profling and RNA tag sequencing the response of Saccharomyces cerevisiae to nitrogen deficiency and profiling Neurospora crassa early sexual development. Priming with MTPs in addition to oligo-dT resulted in higher sensitivity, a greater number of well-measured genes, more genes significantly differentially expressed, and a greater power to detect meager differences. Saccharomyces cerevisiae S288c was grown on two different media.

<h4>Background</h4>Complementary approaches to assaying global gene expression are needed to assess gene expression in regions that are poorly assayed by current methodologies. A key component of nearly all gene expression assays is the reverse transcription of transcribed sequences that has traditionally been performed by priming the poly-A tails on many of the transcribed genes in eukaryotes with oligo-dT, or by priming RNA indiscriminately with random hexamers. We designed an algorithm to fin  ...[more]
