In a study most of the plants saw augmentations of more than 20%; one strain improved by a third. Those numbers could make a big difference in a world at risk of losing farmland to climate change
Save time by listening to our audio articles as you multitaskUnderstanding how plants do this is scientifically fascinating. It also offers the possibility of changing not just the look and size of members of the vegetable kingdom, as humans have been doing for ten millennia, but also their inner workings.
The latest experiments with soya were designed to put those worries to rest. Dr Long and his colleagues took the genetic troika from their tobacco experiments and inserted it into Maverick, a soya cultivar that is reasonably easy to manipulate genetically. The vagaries of such manipulation mean that the same genes added to the same plant do not always give the same result, so the researchers created a range of strains. In 2020 they planted eight of them on the university’s farm.
In their new, recumbent pose the plants’ leaves were piled on top of each other, rather than waving free. Those above got more light all the time; those below, less. None saw much by way of variation. Such efforts are not restricted to soya. Rice and wheat are other possibilities. Work aimed at putting the technology into seeds of these crops and others, which can then be provided to farmers—in particular, poor farmers—will be taken on by Gates Ag One, a company owned by the Bill & Melinda Gates Foundation, which helps fund Dr Long’s lab.
