Genetic analysis of <i>hrs1-1</i> germination.

<p>Germination rate (TI, mean ± SD, each calculated using the measurements from triplicate samples) was used to compare the germination behavior of different genotypes. The datasets presented are each representative of at least three independent experiments. Based on multiple statistical comparisons, the means labeled by one or more identical letters do not differ significantly from each other (<i>P</i>≤0.05). (A) Comparisons of the germination rates of WT control, four single mutants (<i>hrs1-1</i>, <i>abi3-8</i>, <i>abi4-1</i> and <i>abi5-7</i>), and three double mutants (<i>hrs1-1abi3-8</i>, <i>hrs1-1abi4-1</i> and <i>hrs1-1abi5-7</i>) on 1/2 MS medium or those with two different concentrations of ABA. (B) Comparisons of the germination rates of WT control, two single mutants (<i>hrs1-1</i> and <i>abi1-2</i>), two double mutants (<i>hrs1-1abi1-2</i> and <i>hab1-1abi1-2</i>), and one triple mutant (<i>hrs1-1hab1-1abi1-2</i>) on 1/2 MS medium or those with two different concentrations of ABA. (C) The germination rates of WT control, four single mutants (<i>hrs1-1</i>, <i>abi3-8</i>, <i>abi4-1</i> and <i>abi5-7</i>), and three double mutants (<i>hrs1-1abi3-8</i>, <i>hrs1-1abi4-1</i> and <i>hrs1-1abi5-7</i>) on 1/2 MS medium or those containing two concentrations of NaCl. (D) The germination rates of WT control, two single mutants (<i>hrs1-1</i> and <i>abi1-2</i>), two double mutants (<i>hrs1-1abi1-2</i> and <i>hab1-1abi1-2</i>), and one triple mutant (<i>hrs1-1hab1-1abi1-2</i>) on 1/2 MS medium or those supplemented with two concentrations of NaCl.
