So while the fight continues to get GMO's labeled we have this:

Crop plants with DNA deletions are not GMOs

This study ushers in a new era in crop breeding. Plant geneticists will now be able to use TAL-nucleases to introduce precise, favorable modifications in any region of the genome. Remarkably, because Li and colleagues have bred out the TAL sequences, the resulting rice varieties lack any foreign DNA.

Instead of adding a sentence or two to the genome book, as is done by standard genetic modification (GM) approaches, they removed a few letters; the rice varieties they generated lack anywhere from 3 to 57 bases in their genomes (as in the Figure to the right from the Li paper). Thus, the rice plants generated by Li et al. do not contain extraneous DNA and cannot by any reasonable definition be considered “GMOs.”
