Researchers from Jiangsu Academy of Agricultural Sciences and Yangzhou
University in Chinadeveloped low glutelin rice using the CRISPR Cas9gene
editing system. Their findings are published in/Plant Science/.

Chronic kidney disease and phenylketonuria patients are required to
consume ricewith low glutelin content. Thus, one of the goals of rice
breeders is to come up with high-yielding rice varieties with low
glutelin and delicious taste.

The research team used CRISPR-Cas9 to simultaneously edit up to 7
genesinvolved in the production of glutelin in rice. Results showed that
two out of the nine edited lines had significantly lower glutelin
content, which is even reduced than low glutelin content cultivar LGC-1.
These two lines also have similar agronomic characteristics and
viscosity properties as the wild-type, indicating their potential as new
varieties or parental materials for breeding low glutelin rice.
