Figure 5.

RNA decay profiles of single probes of glsF (ferredoxin-dependent glutamate synthase) - the longest gene (4.6 kb) in Prochlorococcus MED4. Single microarray probes are localized up to 1.2 kb (light blue lines), between 1.3 and 2.4 kb (green lines) and between 2.5 and 4.5 kb (orange lines) downstream of the start codon. The microarray signal intensity (expression) was normalized to time 0 h. Only probes with an expression value above 100 at time 0 h are shown.
