Schematic of stem cell niche organization and maintenance in the plant shoot apical meristem (SAM) and root apical meristem (RAM).

<p>This conserved pathway involves feedback regulation of transcription by CLE dodecapeptides. The organizing center (OC) in SAM stem cell niche and the quiescent center (QC) in RAM stem cell niche are indicated in red in the diagram (Adapted from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0089241#pone.0089241-Murphy1" target="_blank">[3]</a>).</p

CLV3-QD localizes to the cell membrane of <i>Arabidopsis</i> root protoplasts.

<p>A. Bright field of control cells with QDs; B. fluorescent field of control cells incubated with QDs. After incubation, the probes were washed and no fluorescence was observed; C. Bright field of cells incubated with CLV3-QD probes; D. fluorescent field of C; after incubation, the probes were washed and a green fluorescent circle was observed at the membrane of the cells.
