Performance of selected transgenic lines (L1 & L7) co-expressing <i>AtDREB2A</i>, <i>AtHB7</i> and <i>AtABF3</i> under mannitol-induced stress at seedling stage.

<p>The seedlings were exposed to mannitol (200 mM) for seven days and photographed (<b>a</b>). The seedlings were then allowed to recover from stress for 15 days (<b>b</b>). The relative root growth after stress (<b>c & d</b>) and recovery (<b>e & f</b>) was recorded. The bar represents the mean ± SE (n = 8) (student’s t test; *P<0.05 versus wild-type).</p>
