     This data set describes the temporal expression of 102 genes of
     _E. Coli_ after induction of the expression of SOD (recombinant
     human superoxide dismutase).

_F_o_r_m_a_t:

     'caulobacter' is a 'longitudinal' object containing the data from
     the Schmidt-Heck et al. (2004) experiment. Essentially, this is a
     matrix with with 102 columns (=genes) and 9 rows (=time points). 
     All expression levels are given in log2-ratios with respect to the
     first time point (i.e. the induction at time 0).

_S_o_u_r_c_e:

     The micoarray experiment was performed at the Institute of Applied
     Microbiology, University of Agricultural Sciences of Vienne. The
     data and the experiment is described in Schmidt-Heck et al.
     (2004).
