Groups Scientists have created heat-resistant wheat

Groups Scientists have created heat-resistant wheat. A study by scientists from the University of Lancaster is published in The Plant Journal.

Smart thermostats in greenhouses tell air conditioners that they need to turn off after sunset to save energy. A similar process works in plants – it is called Rubisco or RCA. Its activation tells the plant enzyme responsible for growth the need to save energy after sunset.

In a new study, scientists found a way to activate RCA earlier – this will protect crops from the effects of high temperatures, because of which they usually dry out and die.

Naturally occurring wheat varieties Rca 1β has the isoleucine amino acid, which allows it to grow at temperatures up to 39 ° C, but lacks the Rubisco activation mechanism. At the same time, wheat Rca 2β can grow only at temperatures up to 30 ° C, but has a mechanism for activating the energy conservation mode.

Groups Scientists conducted experiments on E. coli E. coli strains, which, like wheat, contain the amino acids isoleucine and methionine. The study allowed the creation of a new version of Rca 2β wheat, which can grow up to 35 ° C, but at the same time uses the Rubisco mechanism.
