Description
Proper developmental fidelity ensures uninterrupted progression towards sexual maturity and species longevity. However, early development, the time-frame spanning infancy through adolescence, is a fragile state since organisms have limited mobility and responsiveness towards their environment. Previous studies have shown that damage during development leads to an onset of developmental delay

Proper developmental fidelity ensures uninterrupted progression towards sexual maturity and species longevity. However, early development, the time-frame spanning infancy through adolescence, is a fragile state since organisms have limited mobility and responsiveness towards their environment. Previous studies have shown that damage during development leads to an onset of developmental delay which is proportional to the extent of damage accrued by the organism. In contrast, damage sustained in older organisms does not delay development in response to tissue damage. In the fruit fly, Drosophila melanogaster, damage to wing precursor tissues is associated with developmental retardation if damage is sustained in young larvae. No developmental delay is observed when damage is inflicted closer to pupariation time. Here we use microarray analysis to characterize the genomic response to injury in Drosophila melanogaster in young and old larvae. We also begin to develop tools to examine in more detail, the role that the neurotransmitter dopamine might play in mediating injury-induced developmental delays.
