Key Points

Promoter editing generated stay-green perennial ryegrass, enhancing its forage quality and heat tolerance.
The modification of the NOL gene led to significant improvements in grass quality amidst high temperatures.
Editing the chlorophyll b reductase gene’s promoter contributed to the stay-green phenotype and better stress response.
These findings support the use of genetic modification for developing crops resilient to climate change.

Implication

Editing the promoter of the NOL gene improves forage quality and heat tolerance in perennial ryegrass, suggesting potential for agriculture.

Abstract

Editing the heat-responsive motif of the promoter of a chlorophyll b reductase gene, NON-YELLOW COLORING 1-like (NOL) generated stay-green perennial ryegrass mutants with improved forage quality and heat tolerance.
