Arabidopsis thaliana members of the CIA and ISC export machineries.
Protein names | AGI numbers | Phenotype(s) of mutant plants | Reference(s) |
---|---|---|---|
NAR1/GOLLUM | At4g16440 | Embryo lethal | Cavazza et al., 2008; Luo et al., 2012 |
CIA1 | At2g26060 | Embryo lethal | Luo et al., 2012 |
NBP35 | At5g50960 | Embryo lethal | Bych et al., 2008b |
AE7/ MIP18/CIA2 | At1g68310 | Strong allele is embryo lethal, weak alleles are viable but exhibit highly accumulated DNA damage and cell cycle arrest | Yuan et al., 2010; Luo et al., 2012 |
MET18/MMS19 | At5g48120 | No phenotype under standard growth conditions | Luo et al., 2012 |
DRE2/CIAPIN | At5g18400 | Embryo lethal | Bernard et al., 2013 |
TAH18/ATR3 | At3g02280 | Embryo lethal | Varadarajan et al., 2010 |
ATM3/ABCB7 | At5g58270 | Defects in root growth, chlorophyll content and seedling establishment | Kushnir et al., 2001; Kim et al., 2006; Bernard et al., 2009 |
ERV1/ALR | At1g49880 | Embryo lethal | Carrie et al., 2010 |
Except ATM3 and ERV1 which code for the two protein components of the ISC machinery, all other genes code for proteins of the CIA machinery. Yeast and human names have been indicated. ATM1 (At4g28630), ATM2 (At4g28620), AE7.2/AEL1 (At3g50845) and AE7.3/AEL2 (At3g09380) genes have not been listed here considering that they are not able to complement atm3 and ae7 mutants. There are putative additional CIA1 (At4g32990) and DRE2 genes (At5g18362) but, from EST or transcriptomic data, there is no evidence that they are expressed.
