Rhizophores arise from angle meristems located at shoot branch points in many species of Selaginella and produce roots at their distal ends. We reinvestigated the origin and development of rhizophores ...

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 ...

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 ...

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 ...

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 ...

Plant stem cells, as in animals, are maintained in specialized microenvironments, which are known as stem cell niches, where local signals from organizer cells act to prevent stem cell differentiation ...
