Functional characterization of SOR1, a gene required for resistance to photosensitizing toxins in the fungus Cercospora nicotianae.

abstract：:Homologous recombination repairs discontinuities in DNA including single-strand gaps (SSGs) and double-strand breaks (DSBs). This commentary describes how the RecBCD and RecF pathways might be exchangeable for the repair of their respective DSB and SSG canonical substrates. In particular, I will discuss how the RecBCD...
