University of Erlangen-Nürnberg: If there’s one thing potato plants don’t like, it’s heat. If the temperature is too high, potato plants form significantly lower numbers of tubers or sometimes none at all.
Biochemists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) in Germany have now discovered the reason why. If the temperature rises, a so-called small RNA blocks the formation of tubers.
The scientists have now successfully switched off this small RNA and have produced potato plants that are more resistant to high temperatures, which is an important contribution to securing crop yields in the future in view of climate change.
They have presented their results in the journal Current Biology published by Cell Press.
