Analysis of Poly(ADP-Ribose) Polymerases in Arabidopsis Telomere Biology

Arabidopsis PARPs respond to genotoxic stress.
(A) Morphological and developmental defects of seedlings grown in increasing concentrations of MMS. Left panel: parp1 and parp2 single mutants. Right panel: parp1 parp2 double mutants. ku70 mutants were used as a positive control for MMS sensitivity. (B) qRT-PCR for PARP expression in wild type seedlings. Seedlings were either treated with 20 µM zeocin/0.6% DMSO or 0.6% DMSO (untreated) for 4 h. PARP3 expression was not detected. * = p-value <0.005 compared to untreated.
