The picture shows a moment in the sample-collecting effort leading to thisPnas paper about a novel heat-tolerant CRISPR enzyme called IgnaviCas9. Exploring nature’s molecular diversity in extreme environmental conditions such as Yellowstone hot springs can yield exciting discoveries and applications.
Around 30% more grain. This is the result announced in PNAS by Chinese researchers that have made the most of CRISPR’s multiplexability in rice. By simultaneously targeting multiple genes, the editing technique is a boon for scientists struggling with plants’ genetic redundancies. Continue reading →
