Stability of E. coli mRNA in presence of hPNPase. Left panel. mRNAs extracted from exponential cultures at 37 °C of C-1a (pnp⁺; Ec), C-5691 (Δpnp; Δ) and C-6001 (PNPT1_Ec; Hs) were divided in four categories with decreasing stability (from 1, most stable, to 4, least stable). Significance of difference of the distribution was estimated with Pearson’s Chi-Square test. *****, P < 0.00001. Right panel. Distribution of mRNAs with lower (L), equal (=) or higher (H) stability in (i) C-1a (pnp⁺; Ec) than in C-5691 (Δpnp; Δ), Ec versus Δ; (ii) C-1a (pnp⁺; Ec) than in C-6001 (PNPT1_Ec; Hs), Ec versus Hs; and (iii) in C-6001 (PNPT1_Ec; Hs) than in C-5691 (Δpnp; Δ), Hs versus Δ. The figures on column sectors indicate thousands of genes belonging to each category.
