Constitutive expression of <i>PeHAB1</i>confers ABA insensitivity in transgenic plants during seed germination and root growth development.

<p>(A) The emergence rate of green cotyledons from Col-0 and <i>PeHAB1</i> transgenic seeds plated on MS medium supplemented with different concentration of ABA. Approximately 100 seeds were used in each experiment. Error bars represent the standard deviation. (B-D) Col-0 and two independent <i>35S</i>::<i>PeHAB1</i> lines were germinated and grown in medium (MS) supplemented with 0.75 μM ABA. Photographs were taken after 14 days. (E-F) Root length in MS medium supplemented with 10 μM ABA and its correspondingly statistical analysis. Data means ±SE from three independent experiments (<i>n</i> = 30 seeds).
