Mapping the Functional Landscape and Viral Diversity of 2A Peptides

2A peptides are short (~18 to 22 amino acid) sequences utilized by a subset of RNA viruses to process their polyproteins in an unusual co-translational event known as StopGo or ribosome skipping. This process involves ribosome pausing at a conserved C-terminal D(V/I)ExNPGP motif, followed by peptidyl-tRNA hydrolysis of the nascent peptide-tRNAGly, and continued translation from the downstream…

Delaying cherry blossom to reduce frost damage

Climate change is causing many fruit trees to flower earlier, increasing their exposure to damaging late spring frosts. A study led by the University of Göttingen shows that the plant growth regulator ethephon can delay flowering in Kordia, a sweet cherry variety, potentially protecting blossoms and developing fruitlets from frost.
