Hydrogen peroxide sensitive 12(hps12)was screened from this library. Phenotype analysis indicated that hps12 had dwarf plant and shorter pod than wild type(WT). The cotyledon greening rate of hps12 was decreased after being treated with 4 mmol/L H_2O_2. Furthermore, the isolated leaves of hps12 mutants showed more obvious symptoms of senescence than WT under the treatment of 10 mmol/L H_2O_2. Genetic analysis suggested that hps12 was a monogenic recessive mutant.展开更多
