Dr. Gregory P. Copenhaver co-authored a paper in Plant Cell with his collaborators at The University of Vienna that is titled “Meiotic DNA Repair in the Nucleolus Employs a Non-homologous End Joining Mechanism”. This paper shows how plants repair chromosomal breaks during meiosis in regions of the genome that contain large repetitive arrays. The arrays, which encode the RNA used to build ribosomes, form a unique compartment in the nucleus that processes meiotic breaks differently to ensure genome stability. You can read more here >>
