A signaling module controlling the stem cell niche in Arabidopsis root meristems. Curr Biol 19, 909-914.Stahl, Y., Wink, R.H., Ingram, G.C., and Simon, R. ( 2009 ). A signaling module controlling the stem cell niche in Arabidopsis root meristems. Curr. Biol. 19: 909 – 914 ....
Shoot stem cells signal back to the OC by secreting the CLAVATA3 (CLV3) dodecapeptide [2], which represses WUS expression [3]. However, the signals controlling homeostasis of the root stem cell system are not identified to date. Here we show that the differentiating descendants of distal ...
In Arabidopsis, lateral root cap (LRC) cells covering the meristematic zone are regularly lost through programmed cell death, while the outermost layer of the root cap covering the tip is repeatedly sloughed. Efficient coordination with stem cells producing new layers is needed to maintain a ...

root epidermal patterningvascular developmentDuring plant development, the frequency and context of cell division must be controlled, and cells must differentiate properly to perform their mature functions. In addition, stem cell niches need to be maintained as a reservoir for new cells. All of these...
Analysis of the Root System Architecture of Arabidopsis Provides a Quantitative Readout of Crosstalk between Nutritional Signals. 2014.

Using this method, we performed a direct measurement of cell division intervals within and around the root stem cell niche. The results reveal a short, steep gradient of cell division rates in proximal stem cells, with progressively more rapid cell division rates from quiescent center (QC), to...
The plant hormone auxin plays a critical role in the maintenance of root stem cell niches in Arabidopsis. We have recently reported that WUSCHEL-RELATED HOMEOBOX 5 (WOX5) transcription factor modulates free auxin production in the quiescent center (QC) of the root and its expression is inhibited...
Recent reports have shown that the molecular mechanisms involved in root stem-cell niche development in Arabidopsis thaliana are complex and contain severa
The growth of plant organs is influenced by a stream of the phytohormone auxin that flows from the shoot apex to the tip of the root1. However, until now it has not been known how auxin regulates the cell proliferation and enlargement that characterizes
