Animal phylogeny: Root and branch surgery
Our view of how-many phyla relate to each other is being radically revised by molecular phylogenetics. For example, arthropods and annelids are no longer placed together, but are now considered to be in separate clades. The new tree has important ramifications for developmental biology and genomics.

15 صفحه اولSean Morrison: A root and branch approach to stem cells
T hroughout life, stem cells maintain themselves by dividing to produce one or two daughter stem cells with an identical developmental potential. Although this self-renewal process is fundamental to all types of stem cells, the precise mechanism varies between different tissues and stages of development. Sean Morrison examines the self-renewal of different types of stem cells to understand how ...
متن کاملControl and Kinetics of Branch Root Formation in Cultured Root Segments of Haplopappus ravenii.
Branch root formation required only the presence of minerals, sucrose as a carbon source, and an auxin. The number of primordia formed was a function of auxin concentration. With naphthaleneacetic acid at 0.1 mg/l, up to 60 or more branches were formed per centimeter of Haplopappus ravenii root segment. Under our conditions, pea root segments formed only five or six branches per centimeter, but...
