Disciplinary IBC area 03: "Structure and Development, Including Functional Aspects"

Symposium 03-22:

"Physiological and ecological aspects of responses to internal and environmental cues"

Organizer: Ariel Novoplansky, Ben-Gurion University of the Negev, Israel.

The organization and adaptations of plants involve pronounced developmental plasticity. This is required both because the environment is unpredictable and must be dealt with without movement and because of the constant changes of the relations between the organs of the developing plant. There is good evidence, from varied systems, that these two aspects of plasticity depend on the very same mechanisms, but this evidence has hardly been discussed and summarized.

Keywords:

Information processing and integration, phenotypic plasticity, internal state, external conditions, organization, differentiation, external and internal signals, hormones, signal perception, environmental cues, predicting future conditions.
