Developmental plasticity: a worm's eye view

Area of Science:

• Developmental Biology
• Environmental Science
• Genetics

Background:

• Phenotypic outcomes vary with environmental conditions across diverse species.
• Nutrient availability is a key environmental factor influencing development.

Purpose of the Study:

• To investigate the impact of environmental variation, specifically nutrient availability, on developmental traits.
• To advance the understanding of developmental plasticity using Caenorhabditis elegans.

Main Methods:

• Utilized Caenorhabditis elegans as a model organism for controlled environmental studies.
• Analyzed wild isolates to understand natural variation in response to food availability.
• Examined organismal, tissue-level, and molecular responses to environmental changes.

Main Results:

• Demonstrated developmental plasticity in response to nutrient variation in C. elegans.
• Identified tissues and molecular pathways mediating environmental translation into plastic responses.
• Observed behavioral changes associated with developmental plasticity.
• Showcased how early life starvation can influence adult physiological traits.

Conclusions:

• Caenorhabditis elegans is a powerful model for studying developmental plasticity and environmental influences.
• Environmental cues, particularly nutrient availability, profoundly shape development and physiology.
• Early life experiences can establish a physiological memory impacting later life stages.
