Can we engineer life? 4.7 Plant gene technology, cisgenesis
In cisgenesis, we insert new DNA in a stable form into plant DNA, just like in transgenesis. The difference being that in transgenesis, the new DNA originates from another species, in cisgenesis from a plant with which the acceptor plant can crossbreed. Researchers from Plant Research International at Wageningen UR have been arguing for almost
Can we engineer life? 4.6 Golden rice
Golden rice symbolizes the protracted trench war between proponents and opponents of modern biotechnology. The Swiss Ingo Potrykus of ETH Zürich is the golden man behind the golden rice. With great ardour he defends this controversial rice, and attacks the opponents of gene technology. With his colleague Peter Beyer of Freiburg University he developed the
Can we engineer life? 4.5 Novel plant breeding techniques
Plants have large and complicated genomes. Therefore, until recently, the insertion of foreign DNA was a kind of roulette: where will DNA be modified, will the insertion work, and will there be side effects? But by now, techniques have much improved and totally novel plant breeding techniques have been developed, carrying names like ZFNs, TALENs
Can we engineer life? 4.4 Plant gene technology, modern techniques
Modern techniques are in very rapid development. We can now analyse the most complex DNAs down to the level of individual base pairs, knowledge that will enable us to continue to produce enough food in times of climate change. And we get an increasing number of techniques to our disposal that make use of this
Can we engineer life? 4.3 Plant gene technology, history
Ever since mankind developed agriculture, we try to selectively breed plants in order to secure enough and good food. Our capabilities to purposely engineer plant genomes have increased a lot over the past few decades. There are many applications of plant gene technology now, and opportunities abound. And we won’t grow food crops with an
Can we engineer life? 4.2 Plant gene technology: Bt aubergines
Anyone attached to Greece (and I am one of them) knows moussaka, one of the most traditional dishes of the Greek kitchen. I have mixed feelings on it, even though I love all ingredients of this oven dish with aubergines as main ingredient. How come? Many Greek chefs add cinnamon to the dish, in addition
Can we engineer life? 4.1 Hunger in the world increases
In September 2017, the FAO released a report on hunger in the world. According to this report, in 2016 11% of the global population experienced hunger, i.e. 815 million people, 38 million more than in the preceding year. This is rather shocking, as the rise comes after a gradual decline in the preceding decade. All
Can we engineer life? 4.8 Plant gene technology, the photosynthesis boost
Photosynthesis is one of the most important biological processes on earth, if not the most important one: no life without photosynthesis! The Rubisco enzyme plays a key role in this process. But from the viewpoint of modern agricultural science, the photosynthesis process is far from perfect. So commentators devoted much hyperbolic praise on a publication
