In GeneCycle: Identification of Periodically Expressed Genes

Description

This data set describes the temporal expression of 1444 genes (open reading frames) in the cell cycle of the bacterium Caulobacter crescentus.

Usage

Format

caulobacter is a longitudinal object containing the data from the Laub et al. (2000) experiment. Essentially, this is a matrix with with 1444 columns (=genes) and 11 rows (=time points)

Source

This data is described in Laub et al. (2000).
