Do yeast cells dream of metabolic sheep?

Rainer Machné

The YRO cohorts were defined by Machné and Murray (2012) as a consensus between time series-based clusterings of transcriptome time series from a short period (Li and Klevecz 2006) and a CDC-coupled (Tu et al. 2005) oscillation.

Below, I show enrichment profiles with other yeast gene classifications, specifically the SGD's GO annotation, a classification of yeast genes into their pre-eukaryotic ancestry (Bogumil et al. 2014), and a classification of cell division cycle phase-specific expression (Spellman et al. 1998) (numbers are overlap counts, gray-scale indicates p-values from cumulative hypergeomtric distribution tests, where black is the minimal shown \(p\le10^{-10}\)), boxplots of the transcripts tRNA and adaptation indices (Man and Pilpel 2007), and t-test profiles of the proteins' amino acid compositions (numbers: t statistic; red: higher, blue: lower than average; color intensity indicates the p-values with full colors \(p\le10^{-10}\)).
