5x increase in rice yields? New lines of CRISPR-created rice could help fight fungal rice pandemic decimating world's rice crop

Thanks to CRISPR, farmers may finally have a good defense against rice blast, a fungal disease so devastating, it’s known as the “cancer of rice.”The challenge: Rice provides more than 20% of the world’s calories, but every year, rice blast wipes out 10-30% of the world’s rice crops, making it a major threat to both global food security and economies that depend on rice production.“Blast is the most serious disease of plants in the world because it affects virtually all growing regions of rice and also because rice is a huge crop,” said Pamela Ronald, a distinguished professor in the Department of Plant Pathology at UC Davis.“The results from this study could help shore up food supply in the future.” Jenny MortimerWhat’s new? Ronald and an international team of researchers have now found a way to use CRISPR to make plants resistant to rice blast. In small field trials, their gene-edited rice plants yielded five times as much rice as controls when challenged

Multi-country effort helps develop gene-edited rice that both boosts yield and resists disease

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.Small-scale field trials in China showed that the newly created rice variety, developed through genome editing of a newly discovered gene, exhibited both high yields and resistance to the fungus that causes a serious disease called rice blast. Rice is an essential crop that feeds half of the world’s population.Guotian Li, a co-lead author of the study, initially discovered a mutant known as a lesion mimic mutant while working as a postdoctoral scholar in Pamela Ronald’s lab at UC Davis. Ronald is co-lead author and Distinguished Professor in the Department of Plant Pathology and the Genome Center.“It’s quite a step forward that his team was able to improve this gene, making it potentially useful for farmers. That makes it important,” Rona
