Dominant negative interference of AtNMD3 function causes pleiotropic morphogenetic defects.

<p><b>A</b>, <b>B</b>. Seventeen-day-old seedlings of wild-type Colombia (Col-0) (<b>A</b>) and AtNMD3ΔNES OE line (<b>B</b>) show similarities in the overall shape. <b>C</b> shows the dwarf phenotype of the AtNMD3ΔNES OE line (right). <b>D</b>. Enlarged image of inflorescence (Col-0 at left). <b>E</b> shows the rosette leaves of the AtNMD3ΔNES OE line having an obvious zig-zag margin. <b>F</b> to <b>I</b> show obviously elongated cells in both adaxial and abaxial leaf sides of the AtNMD3ΔNES OE lines (<b>H</b>, <b>I</b>), compared to Col-0 (<b>F</b>, <b>G</b>). <b>J</b>, <b>K</b> shows the petals of the AtNMD3ΔNES OE lines with less organized cells and no obvious vascular veins (<b>K</b>), compared to that of Col-0 (<b>J</b>). <b>L</b>, <b>M</b> shows reduced stamen of the AtNMD3ΔNES OE lines (<b>M</b>) compared to Col-0 (<b>L</b>). <b>N</b> and <b>O</b> show curved carpel cells of the AtNMD3ΔNES OE lines (<b>O</b>), compared to Col-0 (<b>N</b>). <b>P</b> shows enlarged seeds of the AtNMD3ΔNES OE lines. Bar = 100 µm.
