TL;DR
Scientists used CRISPR-Cas9 to improve rice yield by modifying a specific gene without affecting grain quality.
Contribution
A transgene-free CRISPR-Cas9 method for increasing rice yield by over 20% is introduced.
Findings
CRISPR-Cas9-mediated knockup of OsDREB1C increased rice yield by over 20%.
The modification did not compromise grain quality in the resulting plants.
Homozygous plants were transgene-free, supporting safe crop improvement.
Abstract
This study presents a CRISPR-Cas9-based strategy for engineering structural variations in the OsDREB1C gene in rice, leading to a yield increase of over 20% without compromising grain quality. The resulting homozygous plants are transgene-free, highlighting the potential of this approach for precise and effective crop improvement.
