| This study was carried out to understand the effect of low temperature($4^{circ}C$), heat shock($37^{circ}C$) and drought stresses on the growth and gene expression of Arabidopsis ATSIZ3(at1g08910) mutants. The seedling growth of SIZ3-mutants were markedly inhibited by the treatment of heat shock or chilling stresses. However, there was no significant differences between wild type and SIZ3-mutants in seeding fresh weight. As compared to wild type plants, SIZ3-mutants showed 63.9% inhibition of seedling fresh weight by the treatment of 10 days drought stress, suggesting that SIZ3 is involved in the resistance of Arabidopsis to drought stress. Base on RT-PCR analysis, expression of SIZ3 mRNA in the wild type showed 20% inhibition by chilling stress, 3.7 and 4.5 fold increase by the treatment of heat shock or drought stresses, respectively. |
