Table 1 Spontaneous mutation rates

From: Rice UBC13, a candidate housekeeping gene, is required for K63-linked polyubiquitination and tolerance to DNA damage

Strain^a	Key alleles	Rate^b(×10^-8)	Fold increase^c
DBY747	Wild type	1.28 ± 0.30	1
WXY849	ubc13Δ	31.43 ± 9.48	24.55
WXY849/OsUbc13	ubc13Δ/OsUBC13 ^d	6.76 ± 0.33	5.28

^aAll strains are isogenic derivatives of DBY747.
^bThe spontaneous mutation rates are the average of at least three. independent experiments with standard deviations.
^cRelative to the wild type mutation rate.
^dOsUBC13 cloned in pGAD424, as used in the yeast two-hybrid assay.
