Analysis of Poly(ADP-Ribose) Polymerases in Arabidopsis Telomere Biology
Figure 3
PARP1 and PARP2 negatively regulate expression of each other and PARP3.
qRT-PCR results for PARP1 (A), PARP2 (B), PARP3 (C), and BRCA1 (D) transcripts in seedlings treated with 3-AB and zeocin. All values were calculated relative to wild type seedlings that were not treated with either 3-AB or zeocin. DMSO = no 3-AB; nt = not treated with zeocin; z = zeocin treatment. Student’s two-tailed t-tests were used for statistical analysis. P-values <0.05 are indicated by symbols above the bars for the following comparisons: ‡ = mutant compared to wild type with the same treatment; * = untreated compared to zeocin treated for the same genotype and 3-AB status; § = DMSO compared to 3-AB treated for the same genotype and zeocin status.
