AtXPB1 and AtXPB2: DNA sequences ~90% identical. Linked repeats. atxpb1 mutants:
hypersensitive to MMS, UV-C and HOCl, developmentally delayed, low seed viability, loss of
germination synchrony. Suggests NER is required for removal of lesions during seed storage,
germination and early plant development (Costa et al., 2001)
Gene isolation: Liu et al. (2003). uvh6-1 (missense) mutants are more sensitive to UV-B and UVC (Harlow et al., 1994), small and yellow and have a partial defect in the repair of 6-4
photoproducts (Jenkins et al., 1997; Liu et al. 2003). T-DNA insertion mutants exhibit recessive
lethality (Liu et al., 2003). Gene expressed in all tissues examined (Liu et al., 2003)
At3g61420 and are At1g55750 >80% identical at nt level
Identification of mutant: Jenkins et al., (1995). Gene isolation: Liu et al. (2001). Mutation confers
sensitivity to UV-C, continuous light, H2O2 and ionising radiation and exhibits early senescence
and reduced seed yield. Expressed in all tissues examined
Identification of mutant: Jiang et al. (1997), Hefner et al. (2003). Gene isolation: Hefner et al.
At3g05210
(UVR7/AtERCC1) (2003). Mutants are sensitive to gamma radiation (unlike human homolog), MMC, UV-B, MMS
(slightly) and exhibit 'gamma plantlet' response: irradiated seed germinate normally but the
production of first true leaves is substantially delayed. Like atrad1 mutants, atercc1 mutants
exhibit defective recombination (Dubest et al., 2004)
Identification of mutant: Harlow et al. (1994). Gene isolation: Gallego et al. (2000) Liu et al.
At5g41150
(AtRAD1/UVH1) (2000) Fidantsef et al. (2000). Gene expressed in all tissues examined. Mutants are sensitive to
ionising radiation, MMC, UV-B and UV-C. Mutants exhibit greatly reduced homologous
recombination in the presence of non-homologous overhangs (Dubest et al., 2002). atrad1 mutants
exhibit 'gamma plantlet' response: irradiated seed germinate normally but the production of first
true leaves is substantially delayed (Harlow et al., 1994; Jiang et al., 1997; Hefner et al., 2003).
AtLIGI: Taylor et al. (1998). Complements yeast cdc9 mutant. Expression induced by UV-B (West

The BCD5 and AtBRCA1 encoded proteins are related to both BRCA1 and BARD1 and may be
derived from an ancient progenitor of both. AtBRCA1 is expressed in all organs tested and
transcript levels are increased (up to 800-fold) by ionizing radiation (Lafarge and Montane, 2003).
AtBRCA1 exhibits E3 ubiquitin ligase activity (Stone et al., 2005). BRCA1 mutats are defective
in somatic recombination and MMC sensitive (Block-Schmidt 2011)
AtBRCA2(IV) and AtBRCA2(V) interact with AtRAD51 and AtDMC1. Plants in which both of
the AtBRCA2 genes are silenced exhibit partial sterility and meiotic defects (including the absence
of pairing, synapsis and bivalent formation, defects in anaphase I and II and chromosome
fragmentation) these phenotypes were Spo11 dependent (Siaud et al., 2004)

Some sensitivity to MMC (Block-Schmidt etal., NAR, 2011)
AtRad50 is expressed in all tissues examined, with high transcript levels in tissues containing
many dividing cells (Gallego et al., 2001). atrad50 mutants are sterile and hypersensitive to MMS
(Gallego et al., 2001), and exhibit somatic hyper-recombination (Gherbi et al, 2001), progressive
telomere shortening, and (in cell culture) enhanced cell death (Gallego and White, 2001). The
AtRad50 protein interacts in planta with AtMRE11 (Daoudal-Cotterell et al., 2002)
Identified as homologue: Hartung and Puchta (1999). atmre11 mutants exhibit developmental
defects, including infertility, hypersensitivity to MMS and X-rays, lengthened telomeres, somatic
chromosome instability and Spo11-dependent chromosome fragmentation during meiosis
(Bundock and Hooykaas, 2002, Puizina et al., 2004). Protein interacts in planta with AtRad50
(Daoudal-Cotterell et al., 2002).

AtKu70 interacts with AtKu80; transcript accumulates in response to DSBs (Tamura et al., 2002).
atku70 mutants are hypersensitive to MMS and ionising radiation and exhibit increased telomere
length (Bundock et al., 2002; Riha et al., 2002). AtKu70 is required for telomeric C-rich strand
maintenance (Riha and Shippen, 2003)
At1g48050 more similar to Ku70
AtKu80 interacts with AtKu70; transcript accumulates in response to DSBs (Tamura et al., 2002).
atku80 mutants exhibit telomere lengthening, although telomerase activity per se is not increased
significantly (Gallego et al., 2003). Mutants are hypersensitive to ionising (but not UV) radiation
and exhibit reduced T-DNA intergration frequency (Friesner and Britt, 2003)
Encodes ATP-dependent DNA ligase; expression induced by UV-B and gamma irradiation;
protein interacts with AtXRCC4 (West et al., 2000). Mutants are hypersensitive to ionising (but
