Abundance of mRNAs of flowering-time and circadian-clock–regulated genes in <i>Arabidopsis</i> under long-day control (CK) and drought (DR) conditions.
<div><p>The expressions of <i>GI</i> (<b>A</b>), <i>FKF1</i> (<b>B</b>), <i>CO</i> (<b>C</b>), <i>FT</i> (<b>D</b>) were analyzed by real time-PCR in Ler-0 plants grown in LDs. For each gene, the first peak on the first day under CK conditions was standardized to a level of 1. Open and closed bars along the horizontal axis represent light and dark periods, respectively, measured in hours from dawn. Each experiment was done twice with similar results.</p>
<p>===/ /=== represents the 5-d recovery period with watering. * indicated a significant difference (P<0.05).</p>
<p>DR: Drought treatment began from the 10<sup>th</sup> day age and maintained for 10 days.</p></div
