In 2019, British and Austrian scientists have found that a gradual temperature rise of our planet can significantly reduce yields of some crops. Menopausal changes a particularly strong impact on corn, so it would be nice if it grew in the greatest possible number of regions of the Earth. However, this plant, like many other crops, does not tolerate low temperatures and in cold conditions rarely pleases a large harvest. However, American scientists dared to suggest that the increasing in maize production one of the natural enzyme, you can teach a plant to survive and produce a large harvest in almost any conditions.
The idea of a group of scientists led by Professor David stern has been written in the scientific journal Plant Biotechnology Journal. They have long studied the role of the natural enzyme ribulosebisphosphate (RuBisCO) in plant life and found out one interesting detail. It turned out that the more of this enzyme contains in plants, the more they grow and develop faster. Based on this, scientists have been suggested that forcing corn to produce more of this substance, they will be able to teach her to grow even in cold conditions.
How to accelerate the growth of plants?
To check whether it is possible to increase resistance of maize to cold by increasing in the concentration RuBisCO, scientists conducted an experiment. By editing the genes of plants , they created a strain of corn, which indeed produces more of the aforementioned substances than usual. Created plant was planted near the ordinary corn in container with variable temperature. The first plants for three weeks was grown at 25 degrees Celsius, but then the temperature for two weeks, reduced to 14 degrees and again raised to the original level.
Scientists explained this by the fact that in this way they recreated the conditions under which corn is planted in relatively warm weather and experiencing the cold period. Usually, if the corn is subjected to such temperature fluctuations, plant growth is greatly reduced and good yields from it is not expected. However, rich enzyme RuBisCO corn recovered relatively quickly from the drop in temperature and in contrast to the control plants gave a good harvest.
From this it follows that increasing the concentration of just one enzyme, scientists can develop varieties of plants that are perfectly adapted to cold conditions. Only here at the moment scientists do not know what crops can be subjected to such changes. For this you need to conduct other studies, except that the authors are not going to have that, at least in the near future. Instead, they want to do so in cold conditions the corn gave a stronger cob, because the result got them not completely.
