Climate-associated genetic switches found in plants

Genetic variants that can act as switches directing structural changes in the RNA molecules that code for proteins in plants have been experimentally validated in plants for the first time. The changes to RNA structure can affect the molecule’s stability, how it interacts with other molecules, and how efficiently it can be translated into protein — all of which can impact its function and the traits of the plant.
