RNA gel blots showing alterations to SBEII and GBSS mRNA abundance in transgenic plants. (A)
SBEII mRNA abundance in tubers from plants transformed with a SBEII overexpression construct (1047 lines). (B)
GBSS mRNA abundance in tubers from plants transformed with a GBSS RNAi construct (1041 lines). Wild-type (WT) and empty vector transformants (EV) are shown for comparison. Ethidium bromide (EtBr) staining of RNA (with contrast reversed) was used to confirm the equivalency of loading.
