MON 810 transgenic maize is the unique genetically modified (GM) maize approved for cultivation within the European Union.
Prior “omics” studies on MON 810 maize in comparison with non-genetically modified near-isogenic varieties has given a broad picture on the differences between transgenic and non-transgenic maize. microRNAs are small non-coding RNAs known to regulate gene expression of several genes. Here, in these study we aimed to find differences in expression of coding and non-coding genes caused by the presence of the transgene. For that, we have performed microarrays of mRNA and miRNAs from two pairs of maize (transgenic/ isogenic).
Interestingly, our results indicate possible “side effects” associated with the transgene integration into the host genome.
