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.

An international team has succeeded in propagating a commercial hybrid rice strain as a clone through seeds with 95 percent efficiency. This could lower the cost of hybrid rice seed, making high-yielding, disease resistant rice strains available to low-income farmers worldwide. The work was published Dec. 27 in Nature Communications. 

Due to severe water shortages, rice acres planted in California plummeted by 37% from 2021 to 2022, according to numbers released recently by the U.S. Department of Agriculture's National Agricultural Statistics Service. But now, thanks to University of California researchers, growers have a new tool they could potentially use to cope with droughts and other environmental and socioeconomic changes.

Researchers at the University of California, Davis, have found a way to reduce the amount of nitrogen fertilizers needed to grow cereal crops. The discovery could save farmers in the United States billions of dollars annually in fertilizer costs while also benefiting the environment.

The research comes out of the lab of Eduardo Blumwald, a distinguished professor of plant sciences, who has found a new pathway for cereals to capture the nitrogen they need to grow.

Study of a rice field in Asia found that selective breeding and management decisions maintained crop yields despite climate changes, but those interventions weren’t enough to increase production to meet global demand, according to a paper from University of California, Davis.

Scientists at UC Davis have used CRISPR technology to genetically engineer rice with high levels of beta-carotene, the precursor of vitamin A. The technique they used provides a promising strategy for genetically improving rice and other crops. The study was published today in the journal Nature Communications.

The Foundation for Food and Agriculture Research has awarded more than $1.7 million to University of California, Davis, researchers to identify genes responsible for drought tolerance in rice and test a new energy-efficient food-drying process.

Ozone pollution threatens rice crop; researchers see hope

High levels of surface ozone are damaging rice yields at an alarming rate in China, the world’s largest agricultural producer and one of its most polluted nations, report researchers at the University of California, Davis, and in China.

For the first time, the research team identified a specific stage of the rice plant’s development as being vulnerable to ozone pollution, which they warn has the potential to impact the international rice market and compromise global food security.
