On the left, an Arabidopsis plant is shown, with the growing shoot tip indicated by the orange line. The orange box shows a top view of the shoot tip at higher magnification, with the shoot meristem ...

Many external factors determine the growth of a plant. Light, nutrient and water supply, temperature, and the availability of carbon dioxide. In particular, sudden environmental stress, such as heat, ...

The key to three-dimensional plant architecture lies in precise control over the orientation of cell division. Plant cells divide periclinally to grow radially—leading to thickening—while anticlinal ...

Arabidopsis thaliana shoot apical meristem with multiple flowers radiating out from centre at different stages of development (left) and the shoot apex under a scanning electron microscope where the ...

In Arabidopsis, SEU and SLK2 are redundant components of a regulatory complex that is proposed to promote shoot apical meristem (SAM) formation during embryogenesis. Expression analysis indicates that ...

WEST LAFAYETTE, Ind. — Pools of stem cells in the apical meristems of plants are key to continued growth and development. Understanding how these stem cells are maintained and balanced against ...

Mutations drive evolution, but they can also be risky. New research led by plant biologists at the University of California, Davis, published Nov. 10 in Proceedings of the National Academy of Sciences ...
