My Lords, I am a member of the Secondary Legislation Scrutiny Committee and I can assert that the committee is supportive of the purposes of this statutory instrument. However, the committee has been critical of the presentation of the instrument, as indeed it has been of the presentation of a large number of instruments. I find the objections of the anti-GM lobby to this statutory instrument to be wide of the mark. Its specific objections to the instrument may be disposed of readily as can its wider objections to genetically modified crops.
The main objection that has been raised against the instrument is that it gives no justification for the claim that a genetic modification effected by gene editing could have occurred naturally. In fact, the statement has a very precise meaning. It means that nothing is introduced into the genome by editing it. Only the genes already present in the organism—or crops, which we are actually talking about—will be subject to the editing. The crops will have at least two copies of the gene and, in many cases, there may be more copies. Wheat, for example, has three copies of its genome. Some of the genes may be of a wild variety and others may be of a cultivated variety. The purpose of gene editing would be to ensure the plant has a homogeneous genetic endowment of the cultivated variety. The presumption is that this will lead to a more fruitful crop.
A project aimed at homogenising the genome via selective breeding might take many years and is liable to be time-consuming and expensive. It bears repeating that the process of gene editing will not introduce any alien material into the plant. This fact serves to negate one of the wilder alarms of the anti-GM lobby, which warns that alien genetic material will be introduced into other plants by inadvertent pollination. There are, in fact, no such alien genes to be guarded against.
Another false alarm of the lobby is that genetically modified crops might propagate rampantly, thereby despoiling the natural environment. The truth of the matter is that cultivated crops are largely incapable of self-propagation. This is surely true of cereal crops, which require threshing to release their seeds. Other crops, if they do succeed at reproducing without human intervention, are liable to die out after one or two generations. I believe that we can confidently dispose of the objections to this instrument. It proposes the alleviation of some burdensome restrictions, which have been impeding research programmes in plant science and agricultural science.
