Genetic insights help rice survive drought and flood
Plants — they're just like us, with unique techniques for handling stress. To save one of the most important crops on Earth from extreme climate swings, scientists are mapping out plants' own stress-busting strategies.
A UC Riverside-led team has learned what happens to the roots of rice plants when they're confronted with two types of stressful scenarios: too much water, or too little. These observations form the basis of new protective strategies.
“This one crop is the major source of calories for upwards of 45 percent of humanity, but its harvests are in danger,” said Julia...

New research estimates economic losses due to congestion, inefficiencies
Between wildfires, drought, a trade war and the COVID-19 pandemic, the last few years have been hard on California farmers. But recent research by agricultural economists from UC Davis and the University of Connecticut suggests that economic losses to California agriculture from recent supply chain disruptions may have an even greater economic impact.
In an article titled “‘Containergeddon' and California Agriculture,” researchers estimate that there was a 17% decline in the value of containerized...

Armyworms can be a serious pest in rice. The worms can eat the rice foliate or panicles, and cause yield reductions.
In 2015, a severe outbreak of armyworms caught rice growers by surprise, resulting in yield losses. In a 2018 survey conducted by UC Cooperative Extension, rice growers reported average yield losses in 2015 ranging from 4% to 12%. Since UCCE began a monitoring program in 2016, rice losses to armyworms have been rare, according to Luis Espino, UC Cooperative Extension rice farming systems advisor in Butte and Glenn counties.
To safeguard the rice crop against the pests, UCCE began conducting...

A UC Cooperative Extension specialist says there isn’t enough scientific evidence to warrant consumers making changes to their diets nor to their children’s diets based on recent media reports about levels of arsenic in rice. The issue arose from an analysis by Consumer Reports of white and brown rice from around the world and rice products like rice cereal, rice milk and rice pasta.
“In virtually every (rice) product we tested, we found measurable amounts of total arsenic,” said the article.
However, Carl Winter, UC Cooperative Extension specialist in the...

Imagine if rice – yes, that semiaquatic species that is typically cultivated under partially flooded conditions – could be both flood- and drought-tolerant. Such a rice variety would benefit rice growers and consumers worldwide and would be less vulnerable to weather extremes that may result from global climate change.
Now UC Riverside experiments demonstrate that such rice is already here. Genetics professor Julia Bailey-Serres’ research group reports in a recent issue of
