The 20 most labile mRNAs with their average difference (AD) intensities at each timepoint. Twelve of 20 have unknown or putative functions. High lability may be an indication of regulation at the level of RNA stability. This is known to be the case for cspA, which is extremely unstable at 37° but transiently stable after a shift to 15° (Goldenberg et al. 1996). The lability of cspG suggests that it may behave similarly. Numbers shaded in gray are below the 99% confidence detection threshold (see Methods). *Half-life represents an upper bound.
