Plants have a sophisticated mechanism for monitoring the production of new proteins. The „U1 snRNP“ complex ensures that the protein blueprints are fully completed. This is important because cells tend to halt the process prematurely. This type of quality control, so-called telescripting, was previously known to exist only in animal cells. A research team led by the Martin Luther University Halle-Wittenberg (MLU) has now shown that a similar process also occurs in plants. The study was published in the journal „Nature Plants“.
