Genetic Technology (Precision Breeding) Bill

Neil Hudson Excerpts

2nd reading
Wednesday 15th June 2022 Commons Chamber

[George Eustice]

We have considered these matters in great depth. We ran a consultation. The overwhelming view of scientists are that these precision-breeding techniques, which do not achieve or do anything that could not be achieved through natural breeding processes, are not in fact GMOs. That is our view. That is why we are bringing this Bill forward today. As the hon. Lady knows, there will no doubt be a debate about these matters in both Houses as the Bill progresses.

Precision breeding techniques give us the ability to produce plant varieties with particular traits far more efficiently than was ever possible with conventional breeding. This opens up huge opportunities for our farmers and growers to produce nutritious food with a lower environmental impact.

Precision breeding techniques can improve crop resistance to diseases, reduce the need for pesticides, increase crop yields, improve resistance to climate change, promote drought resistance and reduce the need for fertilisers.

[Dr Neil Hudson (Penrith and The Border) (Con)]

I do not believe that people need to fear this technology. This is not about creating Frankenstein’s monster or introducing DNA from another species. From developing disease resistant crops to bird flu resistance in poultry to PRRS—porcine reproductive and respiratory syndrome —resistance in pigs, there are significant benefits, including: for food security; for the environment; and importantly, for animal health and welfare. Ultimately, there are also significant benefits for public health, as we are reducing medicines and therefore tackling things such as antimicrobial resistance. Does the Secretary of State agree that, ultimately, this can be a win, win, win for food security, animals and people?

[George Eustice]

My hon. Friend, who knows a great deal about animal welfare issues in particular, raises some very important points. He will know that livestock breeders have long selected traits for polled cattle, for instance, so that they can avoid the need for mutations such as dehorning. It is also the case, as he says, that these new techniques offer the potential for us to breed poultry that is naturally resistant to avian flu, which is a major challenge, and some other issues that I will come on to.

[Dr Hudson]

Hear, hear!

[Katherine Fletcher]

Quite. That is a mouthful, but the key here is “transgenic”. We were putting a gene from Escherichia coli—E. coli—into an itty-bitty nematode worm, an animal, and making a cross-species C. elegans. Those little guys were effectively harnessing natural stress repair mechanisms to produce something that we could measure easily.

I was a scientist; I was fascinated by that, but it did not always sit brilliantly with me, and the mechanisms that were used to produce that transgenic environment were at best embryonic and new. It was effectively taking DNA material in vectors such as plasmid, and pebbledashing a target DNA area. We did not know where it was going to land, and we had a lot of wastage where bits of DNA were going in the wrong place. That is not what the Bill is about, and I look forward to going into that in more detail.

[Dr Hudson]

We have heard concerns that people feel that an exogenous species of DNA would be coming in. Does my hon. Friend agree that this technology is not about that? This is not about an external species coming in, and perhaps the Bill could be tightened up by clarifying that, which would appease some of people’s potential fears.

[Katherine Fletcher]

Yes. If the Bill contained a way of opening up the transgenic debate, be that in plants or animals, it would not enjoy my support.

While I have put on a lot of weight since the mid-1990s, science has also massively moved on. In response to the intervention by the hon. Member for Brighton, Pavilion (Caroline Lucas), this is a bit like comparing a 1997 diesel car with modern zero-emissions vehicles. Yes, they both have wheels, go along in a straight line and are called cars, but the two things are completely different. The British public were right to be cautious at the time, but let us explain why this is different. We now know the genome sequences of other target species and plants, and we have exact tools that are effectively like clever genetic snippers that will go along a genome and only cut in the exact place. There is confidence and science behind that point. We then insert something that, as my hon. Friend the Member for Penrith and The Border (Dr Hudson) highlighted, comes from the same species. If we have wheat that does not taste nice but is good at growing in dry conditions, why can we not give it that dry condition gene, so that it tastes nice and is nutritious and can help feed the third world? There are scientists chomping at the bit to have a go at that—I really cannot wait.

As part of my undergraduate degree I went to Rothamsted and saw the scale that has to be put in place for traditional breeding techniques—think fields and fields and fields. Variant 1 has been crossed with variant 2 in a modern way, but it then needs to be tested, because in traditional breeding techniques we basically take the whole genome, throw it up in the air and ask nature to pick one variant out of two. That means we are looking at multiple generations to try to keep the tasty wheat, as well as the dry, coarse wheat. This is a fantastic opportunity to use fewer resources while doing that research, and to use fewer resources from the environment.

Let me highlight some of the extremely exciting opportunities that I have pulled out of the literature: disease-resistant wheat that needs less pesticide, as mentioned by the Secretary of State; tomatoes with a little extra vitamin D; wheat with reduced asparagine to ensure that people are not exposed to carcinogens, especially if, like me, they cannot cook properly and always burn everything; or chickpeas with high protein levels that help those who are making an environmental choice by being vegan or vegetarian. The possibilities for health, climate, environment, farming and our planet are as endless as the natural variation within species that had Darwin so fascinated. We must do this, and I totally support the Bill.
