Of the 64 plants screened, the ratio was 43 to 21 NptII positive to negative plants, which is consistent with a 3: In contrast, if suppression were due to transcriptional or post-transcriptional gene silencing, accumulation of the message would be reduced, suggesting transgene-associated suppression was not due to repression of endogenous PG mRNA transcription but to RNAi Brodersen and Voinnet, The right to obtain and reuse their personal data for their own purposes across different services.
