- Title
Plant development: An axis of auxin.
- Authors
Kepinski, Stefan; Leyser, Ottoline
- Abstract
The article presents a study related to plant development. In multicellular organisms, different kinds of cell are specialized for different tasks, reproduction, or light perception. Embryos have two distinct ends, which become apparent early on. A role for auxin in elaborating the embryonic axis has been suspected for many years, not least because polarity defects can be induced in embryos by blocking auxin movement. To follow the responses of embryos to auxin, the researchers introduced a gene for green fluorescent protein, attached to a synthetic control region that is activated by auxin.
