Abstract

Arecent report in PNAS by Asahina
et al. (1) addresses the fascinating
question of tissue repair
in plants. According to recent
suggestions, plants and animals might
share cellular mechanisms that allow regeneration
of tissues after damage (2).
However, plants and animals differ greatly
in their mode of development and their
ability to respond to damage-inducing environmental
factors (3). Terrestrial plants
cannot move their whole body in response
to environmental cues, and, because of
their cell walls, they also lack cellular mobility
within the plant. This means that
plants must regenerate damaged tissue
through cellular regeneration at the point
of damage. Traditionally, this regeneration
was considered to occur by dedifferentiation
of existing mature cells followed by
cell division to form callus and differentiation
to form the cellular constituents of
the new tissue, although details of this
process have been questioned recently
