Inter-plant Communication of Genome Instability in Radiation Exposed Arabidopsis

摘要

Bystander effect is the phenomenon of the response of naive hystanding cells or organisms to the stress experienced by neighboring cells or organisms. It is well documented for animal cells grown in vitro, and there are some reports of similar response on the level of the whole organism and even between stressed and non-stressed organisms. Here we present the evidence of the existence of communication between stressed and non-stressed plants. We show that naive plants neighboring plants exposed to X-ray or UVC exhibit similar increase in the frequency of homologous recombination as exposed plants. We present the evidence that communication signal is primarily airborne.
