a

The CHR number corresponds to the chromatin remodeling gene number given in the Plant Chromatin Database (http://www.chromdb.org).

b

The name of the homolog is given or of the gene itself (underlined) whenever it has been previously characterized.

c

The response of the RNAi or both RNAi and mutant (in italics) plants to γ-irradiation (γ-IR) or UV-C (254 nm) is indicated as sensitive (S), resistant (R), similar to wild type (WT), or not determined (ND). The intrachromosomal recombination rate (ICR) is indicated as similar or reduced compared to WT. For GYMNOS, two mutant alleles and one RNAi line were tested and gave the same results. For At5g63950, only the mutant line was tested.
