Knowlegde about genes controlling natural variation for seed dormancy in Arabidopsis

The genetics of seed dormancy was studied in 7 recombinant inbred line populations and revealed map positions for 12 QTls. For one locus (DOG1) the underlying gen was cloned by a combination of fine mapping and mutant approaches. This gene encodes a bZIP transcription factor and knock out mutants show except for a complete lack of dormancy no other plant phenotype. This specificity makes it possible to use such a gen for the modification of seed dormancy either by marker assisted selection or by transgenic approaches.
