Sugar signaling modulates SHOOT MERISTEMLESS expression and meristem function in <i>Arabidopsis</i> Open
In plants, development of all above-ground tissues relies on the shoot apical meristem (SAM) which balances cell proliferation and differentiation to allow life-long growth. To maximize fitness and survival, meristem activity is adjusted t…

Growth history leaves a geometric trace in puzzle cells Open
Puzzle-shaped epidermal cells not only reduce mechanical stress during organ growth but also record the expansion history of the tissue in their outlines. By combining mechanical simulations with time-lapse imaging, we show that transition…

Sugar signaling modulates SHOOT MERISTEMLESS expression and meristem function in Arabidopsis Open
SUMMARY In plants, development of all above-ground tissues is controlled by the shoot apical meristem (SAM) which balances cell proliferation and differentiation to allow life-long growth. To maximize fitness and survival, meristem activit…

FERONIA and microtubules independently contribute to mechanical integrity in the Arabidopsis shoot Open
To survive, cells must constantly resist mechanical stress. In plants, this involves the reinforcement of cell walls, notably through microtubule-dependent cellulose deposition. How wall sensing might contribute to this response is unknown…

Research data supporting "Nitrate modulates stem cell dynamics in Arabidopsis shoot meristems through cytokinins" Open
Data is made of z-stacks (Format: Zeiss .lsm files that can be opened with Fiji (ImageJ)) obtained by confocal microcopy. Each file is a stack of a single meristem. Images were taken with a Zeiss LSM780 or with a Zeiss LSM700 confocal micr…

Nitrate modulates stem cell dynamics in <i>Arabidopsis</i> shoot meristems through cytokinins Open
Significance Plants generate organs throughout their life as a consequence of the maintenance of postembryonic stem cell niches in meristems. The molecular mechanisms controlling stem cell homeostasis and organ emergence in shoot meristems…

Nitrate modulates stem cell dynamics by regulating<i>WUSCHEL</i>expression through cytokinins Open
The shoot apical meristem (SAM) is responsible for the generation of all of the aerial parts of plants 1 . Given its critical role, dynamical changes in SAM activity should play a central role in the adaptation of plant architecture to the…
