Recent reports have shown that the molecular mechanisms involved in root stem-cell niche development inArabidopsis thalianaare complex and contain several feedback loops and non-additive interactions that need to be analyzed using computational and formal approaches. Complex systems cannot be understood in...
In this review, the functions of receptor-like kinase signaling in regulating Arabidopsis root development will be examined in the areas of root apical meristem maintenance, regulation of epidermal cell fate, lateral root development and vascular differentiation.Frans E.

In the root stem cell niche, auxin function is mediated by the action of PLT proteins, which form a gradient from stem cell niche to elongation or differentiation zone15,16. On the other hand, cytokinin interacts with auxin in an antagonistic manner to regulate root development17,18. Auxin ...

KEY MESSAGE: The core regulators which are required for primary root growth and development also function in lateral root development or lateral root stem cell niche maintenance. The primary root systems and the lateral root systems are the two important root systems which are vital to the survival...
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 root cap protects the stem cell niche of angiosperm roots from damage. 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 co...
