Abstract

Using a zinc finger nuclease (ZFN) that creates a site-specific DNA double-strand break (DSB) at the endogenous ADH1 locus, we provide genetic evidence that histone H2AX and DSB-induced small RNAs modulate DNA repair by both non-homologous end-joining (NHEJ) and homologous recombination (HR) in the model plant Arabidopsis thaliana.

Keywords: Arabidopsis thaliana; DNA double-strand break (DSB) repair; H2AX; Small RNA; Zinc finger nuclease (ZFN).
