Rice is a staple food crop for more than half the world’s population, but most farmers don’t grow high-yielding varieties because the seeds are too expensive. Researchers from the University of California’s Davis and Berkeley campuses have identified a potential solution: activating two genes in rice egg cells that trigger their development into embryos without the need for fertilization, which would efficiently create high-yielding clonal strains of rice and other crops.

Researchers from the University of California, Davis, and an international team of scientists used the genome-editing tool CRISPR-Cas to create disease resistant rice plants, according to a new study published in the journal Nature June 14.
