SSCP profiles of RT-PCR-amplified 16S rRNA sequences from total RNA extracted from the larvae of the second instar stage using SIP-RNA. Larvae had been fed with the leaves of tobacco plants grown in a 13CO2-atmosphere (+13C) or a control with normal atmospheric CO2 (−13C). Total RNA was separated on trifluoroacetate gradients separating 13C RNA from 12C RNA.
