Scientists Optimize Prime Editing for Rice and Wheat

By | Agriculture, News, Plant Science

Many genetic and breeding studies have shown that point mutations and indels (insertions and deletions) can alter elite traits in crop plants. Although nuclease-initiated homology-directed repair (HDR) can generate such changes, it is limited by its low efficiency. Base editors are robust tools for creating base transitions, but not transversions, insertions or deletions. Thus, there is a pressing need for new genome engineering approaches in plants.

Photosynthesis varies greatly across rice cultivars—natural diversity could boost yields

By | Agriculture, IRRI, News

A team of researcher examined how 14 rice diverse varieties photosynthesize—the process by which all crops convert sunlight energy into sugars that ultimately become our food. Looking at a little-studied attribute of photosynthesis, they found small differences in photosynthetic efficiency under constant conditions, but a 117 percent difference in fluctuating light, suggesting a new trait for rice breeder selection.
