Longitudinal monitoring of individual infection progression in .

The innate immune system is critical for infection survival. is a key model for understanding the evolution and dynamics of innate immunity. Current toolsets for fly infection studies are limited in throughput and, because of their destructive nature, cannot generate longitudinal measurements in individual animals.

The mode of expression divergence in fat body is infection-specific.

Transcription is controlled by interactions of -acting DNA elements with diffusible -acting factors. Changes in or factors can drive expression divergence within and between species, and their relative prevalence can reveal the evolutionary history and pressures that drive expression variation. Previous work delineating the mode of expression divergence in animals has largely used whole-body expression measurements in one condition.
