Comparative analysis of seed germination and root length between AaPP2C1-OX and wild type Arabidopsis. (a) Seed germination rate of AaPP2C1-OX Arabidopsis higher than wild type. (b) Statistics of seed germination rate. (c) The root length of AaPP2C1-OX Arabidopsis longer than wild type in the presence of the indicated ABA concentrations is shown. (d) Statistics of root length. (e) Reduced expression of ABA-inducible genes in AaPP2C1 overexpression Arabidopsis. The mRNA levels of the indicated genes were determined by Q-PCR analysis using total RNAs isolated from 10 μM ABA-treated plants for 3 h. SD (standard deviation) indicates three independent tests. , -test.
