Some species of Cactaceae from the Sonoran Desert are characterized by a determinate growth pattern of the primary root, which is important for rapid lateral-root formation and seedling establishment.

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 ...

Journal of Experimental Botany, Vol. 46, No. 282 (JANUARY 1995), pp. 19-25 (7 pages) DNA synthesis in cell nuclei and organelles in the root apical meristem of rice was analysed by anti-BrdU ...

WEST LAFAYETTE, Ind. – A Purdue University study has uncovered mechanisms that lead to stem cell formation and maintenance in plants. The findings may one day allow scientists to manipulate stem cell ...

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, ...

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 ...

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 ...

A close-up of the maize shoot apical meristem, a pool of plant stem cells being studied by plant biologist Michael Scanlon as part of a $1.8 million 5-year continuing NSF grant. Disclaimer: AAAS and ...

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 ...

Imagine if our bodies could grow new organs throughout our entire lives. Plants do this constantly, thanks to tiny, powerful ...
